Logo Diffusion Platform Help

Logo Diffusion (logodiffusion.com, Logo Diffusion Inc.) is a credit-metered AI logo generator built on its own diffusion stack: text-to-logo, sketch-to-logo and image-to-logo, plus a Magic Editor, vectorizer, mockup generator, creative upscaler, background remover and style transfer. It sits in the AI logo cluster beside /sales-looka, /sales-brandmark and /sales-logogen, and the boundary matters: a logo is downstream of a locked name, which is downstream of a validated idea. Two facts decide most questions here: the homepage and the pricing page disagree by up to 4x on the vector-export allowance — the number that actually binds — and the Terms make ownership conditional on your plan AND your employer's revenue. Everything is metered in credits, exports included, so "how many logos" is never the right question.

Step 1 — Gather context

If references/learnings.md exists, read it first. Ask only what you can't infer:

1. What are you trying to do? (A) plan sizing — which tier, how many vectors, credits running out; (B) rights — ownership, commercial use, the CC licence, trademark; (C) privacy — public generations, client confidentiality; (D) billing — refunds, an AppSumo lifetime deal, a disputed charge; (E) automation — API, bulk, scripting; (F) evaluating — is this legit, are the numbers real, should I promote it.
2. Where does the logo end up, and who is the user's employer? Print/embroidery/signage/a trademark filing needs a vector, the metered constraint. If they work for a company over $1M annual revenue, the ownership answer changes on plan alone — ask before answering any rights question.
3. Have they paid yet, and through which door? Subscription, the $15 Starter Pack, or an AppSumo lifetime deal — different entitlements, and the LTD cohort has a known grievance. Skip-ahead: need the name → /sales-namelix; choosing a logo tool market-wide → /sales-idea-validation.

Step 2 — Route or answer directly

When routing, give the exact command: "This is a {domain} question — run: /sales-namelix {original question}". Otherwise answer Logo Diffusion-specific questions using Step 3.

Step 3 — Logo Diffusion platform reference

Read references/platform-guide.md for the full reference — the capability table with automation tags; both pricing ladders side by side with the contradictions marked; credit costs per operation; the terms analysis (ownership tiers, the CC BY-NC default, public-by-default, no refunds, arbitration); the affiliate-rate discrepancy; and how to verify pricing yourself. Read references/logodiffusion-api-reference.md for the automation surface — what the exposed FastAPI backend actually is, why it is not a product API, and the supported alternatives for volume. Answer using only the relevant section — don't dump the guide.

Step 4 — Actionable guidance

• Whenever plans, pricing or "which tier" come up, say up front that Logo Diffusion's own two pricing surfaces disagree — and size the plan on the vector-export number. The homepage table lists Basic 50 / Pro 100 / Elite 250 vector exports; /pricing lists up to 200 / 500 / 1,200 for the same tiers — a 4x gap on the one allowance that decides whether a mark can go to print. They also disagree on the Starter Pack's commercial licence (1 logo vs 3 logos) and the annual discount ("Save 2 Months" ≈17% vs "Save 20%"), and the pricing page's own FAQ structured data says the free plan has 20 credits while both tables say 24. Never quote a single number as fact — give the range, name both sources, and tell the user to confirm the vector allowance in-account before paying. Everything shares one credit balance (text-to-logo 2, image-to-logo 5, vectorize 5 / HQ 8, background removal 2, upscale 2x 5 / 4x 20), so exports compete with generations.
• On any ownership or commercial-use question, check the plan AND the employer's revenue first — and never repeat the "Your logos stay yours" headline unqualified. The Terms set three tiers: free users do not own their logos at all, receiving only a Creative Commons BY-NC 4.0 licence — non-commercial, attribution required, so a free-tier mark cannot legally be a business logo; paid members own their assets; but an employee or owner of a company over $1,000,000 USD annual gross revenue must be on Elite or Enterprise, per individual, or they own nothing they create — a Basic or Pro subscriber at such a company is not covered, and the Terms add that if unsure, "assume that it does" apply. Flag the drafting defect rather than glossing it: the clause names Creative Commons Noncommercial "4.1" — no such version exists — while linking to the 4.0 legalcode. Then close as every logo answer should: a licence is not a trademark — require USPTO/EUIPO clearance plus a reverse-image search before spending on the mark, and note US practice generally denies copyright registration to purely AI-generated work.
• Raise the public-by-default clause unprompted on any client-work, NDA or confidentiality question. The Terms state that by default your images are publicly viewable and remixable, that Logo Diffusion "allows others to use and remix your images and prompts," and that only an "Elite" plan "can bypass these public sharing defaults" — while /pricing sells "private image generation" from Basic up. Treat that as unresolved, not a settled feature: for confidential client work, verify privacy in-account before uploading a brief and assume Elite is the only tier the contract backs. Also warn that users grant Logo Diffusion a perpetual, worldwide, irrevocable, sublicensable, royalty-free licence over both their prompts and generated assets, which survives termination.
• State plainly that Logo Diffusion has no public API, and that the FastAPI service you can find is not one. There are no REST docs, no webhooks, no Zapier/Make connectors and no MCP server. A developer poking at the app subdomain will find a live Swagger UI and full OpenAPI spec — that is the internal generation backend (GPU workflow orchestration), not a product surface: undocumented, no declared authentication scheme, no consumer versioning, closeable without notice. Tell users not to build on it, never present the missing authentication as permission to use it, and give the contractual reason: the Terms enumerate "You may not use automated tools to access, interact with, or generate Assets through the Services," making both scripting it and driving the UI with a headless browser a stated breach — against a contract reserving suspension "at any time, and for any reason." The Terms also bar competitive research and reverse engineering and limit accounts to one user each. For volume, route to /sales-ideogram (documented REST API, official MCP server) and vectorize downstream.
• On any billing question, lead with the no-refund clause, and treat AppSumo buyers as a separate case. The Terms say a cancelled or terminated account "will not be refunded for the current subscription period" — the contract's only use of the word — and there is no guarantee, trial-refund or withdrawal clause anywhere. Credits are plan-scoped and the $15 Starter Pack expires in a 30-day window. For AppSumo lifetime-deal holders — deal sold out, with reviewers reporting free-tier access at 40 credits that never renewed and unanswered support — direct them to AppSumo's own refund/dispute process, since AppSumo is the merchant of record and the vendor publishes no refund path. Everyone else: screenshot the plan card and receipt at purchase, cancel in-app before renewal, and treat a card chargeback as the realistic recourse. Disputes otherwise go to binding arbitration under AAA ICDR Expedited Commercial Rules in Santa Clara County, California; UK/EU buyers should cite statutory distance-selling rights as the backstop.
• Treat Logo Diffusion's own marketing numbers as unverified, and say so when asked whether it's legit — especially before anyone promotes it. The site claims 1.4m+ users on the homepage and /for-agencies but 250k+ users on /affiliates. The agency page offers "Start your free month… Full access for 30 days" — a trial that exists on no pricing surface, where the free plan is 24 credits with no downloads and no commercial rights — under a Shopify/Webflow/Notion/Figma/Canva/Dribbble logo wall that is not a customer claim. And the affiliate programme advertises 20% in two places and 35% recurring in a third, while the binding Affiliate Terms §2 say 15%, payable only after vendor approval, with immediate forfeiture of all unpaid commissions on a termination allowed "with or without notice," unexplained and un-appealable. Anyone weighing promoting it should be told the binding rate is 15%. Independent signal is thin: roughly 3.3/5 across ~33 AppSumo reviews.
• When output quality comes up, name the known failure mode instead of suggesting prompt fixes. The most-repeated complaint is that it cannot render text correctly — "it cannot get words spelled right, even when you have used the app's importance arrows" — which is fatal for a wordmark. Steer users to generate the icon/symbol here and set the wordmark in real type in a vector editor afterwards. Users also report hard generation caps below their credit balance and colour drift from the brief.

Gotchas

Best-effort from research (2026-07) — pricing, plan contents and terms were read from Logo Diffusion's own pages, sitemap and /tos rather than from review sites, but they can change without notice. Verify in-account before paying.

• The two pricing surfaces contradict each other on the binding number. Vector exports: homepage says Basic 50 / Pro 100 / Elite 250; /pricing says up to 200 / 500 / 1,200. Starter commercial licence: 1 logo vs 3 logos. Annual discount: "Save 2 Months" vs "Save 20%". Free credits: 24 in both tables, 20 in the pricing page's own FAQ structured data. Quote ranges, not numbers.
• Everything is metered from one credit balance, exports included — text-to-logo 2, image-to-logo 5, vectorize 5 (HQ 8), background removal 2, upscale 2x 5 / 4x 20. The Starter Pack's 300 credits expire in a 30-day window.
• Ownership is conditional twice over. Free users do not own their logos — they get CC BY-NC 4.0 (non-commercial, attribution), so a free mark can't be a business logo. Employees/owners of companies over $1M annual revenue need Elite or Enterprise per person; Basic and Pro don't confer ownership. The clause cites a nonexistent "4.1" version while linking to 4.0.
• Generations are public and remixable by default, and the Terms give only Elite the ability to "bypass these public sharing defaults" — though /pricing sells private generation from Basic. Users also grant a perpetual, irrevocable, sublicensable licence over prompts and assets that survives termination.
• No refunds. "You will not be refunded for the current subscription period" is the contract's only use of the word; no guarantee, trial-refund or withdrawal clause exists. Arbitration is AAA ICDR Expedited, Santa Clara County, California.
• No public API, webhooks, Zapier/Make or MCP. The FastAPI Swagger UI and OpenAPI spec on the app subdomain are the internal generation backend — no declared auth, no consumer versioning, subject to change. The Terms bar automated tools for access or generation, bar competitive research and reverse engineering, and limit one user per account. Route volume to /sales-ideogram.
• Text rendering is the known weak spot — wordmarks come back misspelled. Generate the icon here; set type externally. Reviewers also hit generation caps below their credit balance.
• AppSumo LTD holders are a distinct, aggrieved cohort — deal sold out; reports of free-tier access at 40 non-renewing credits and unanswered support. Their recourse is AppSumo, not the vendor.
• The public numbers don't reconcile — 1.4m+ users on the homepage vs 250k+ on /affiliates; a "full access for 30 days" agency trial that exists on no pricing page; affiliate commission advertised at 20% and 35% while the binding Affiliate Terms say 15%, forfeitable on notice-free termination.

Examples

Example 1: "Which plan do I need? I have three client logos going to print this month."

User says: "I'm a freelancer. Basic looks like enough — 1,000 credits is loads."
Skill does: Reframes off credits onto vector exports, then says plainly that Logo Diffusion's own two pages disagree — the homepage credits Basic with 50 vector exports, /pricing with up to 200, a 4x gap on the exact allowance deciding whether a mark can go to print. Explains the shared meter: vectorizing costs 5 credits (8 in HQ) from the same balance as generation, so 1,000 credits is not 500 logos and 200 vectors. Flags the second contradiction they'd hit at checkout — the Starter Pack is sold as 1 logo of commercial licence on the homepage and 3 logos on /pricing. Recommends confirming the vector counter in-account on the cheapest tier before committing, and warns text will likely come back misspelled, so the wordmark should be set in real type afterwards. Adds the rights check a freelancer needs: if any client is a company over $1M revenue and the work is on their behalf, Elite is the tier that confers ownership.
Result: The user sizes on the constraint that binds, and knows which number is disputed before paying.

Example 2: "Can I script Logo Diffusion to generate concepts overnight? I found their Swagger page." (developer/automation)

User says: "There's an OpenAPI spec on their app subdomain with generation endpoints and it doesn't even need a key."
Skill does: Confirms what they found, then tells them not to build on it. That service is the internal generation backend — GPU workflow orchestration behind the web app, not a product API: undocumented, no declared authentication scheme, no consumer versioning, closeable without notice, so any integration is one deploy from breaking. Gives the contractual reason as well as the engineering one: the Terms enumerate "You may not use automated tools to access, interact with, or generate Assets through the Services," making both scripting the endpoints and driving the UI with a headless browser a stated breach — against a contract reserving suspension "at any time, and for any reason," separately barring competitive research, and limiting accounts to one user. Notes there is no webhook, Zapier/Make or MCP surface either. Routes the job to /sales-ideogram, which publishes REST endpoints and an official MCP server, with vectorization downstream.
Result: No integration built on an internal endpoint, no ToS breach, and a sanctioned path to the same outcome.

Example 3: "Is Logo Diffusion legit? It says 1.4 million users and I want to promote it for 35%."

User says: "I run a design newsletter. The affiliate page says 35% recurring, better than anything else I promote."
Skill does: Separates "is the product real" — it is, and it ships — from "are the numbers real," which don't reconcile. The site claims 1.4m+ users on the homepage and 250k+ on its own affiliates page. Its agency page advertises "full access for 30 days, no credit card," a trial appearing on no pricing surface — the free plan is 24 credits with no downloads and no commercial rights — under a Shopify/Webflow/Notion/Figma/Canva/Dribbble logo wall that isn't a customer claim. On the offer itself: the affiliates page says 20% in two places and 35% recurring in a third, but the binding Affiliate Terms §2 say 15% — and §7 permits termination "with or without notice" with immediate forfeiture of all unpaid commissions, no stated reason and no appeal, while §4 makes the vendor's own dispute decisions "final and binding." Adds the audience risk: independent signal is ~3.3/5 across ~33 AppSumo reviews, with LTD buyers reporting they were left on free-tier credits — the same readers being sent to buy.
Result: The user evaluates on the binding contract rather than the advertised rate, and doesn't stake list trust on it.

Troubleshooting

"I still have credits but it won't generate anything / says I've hit my limit"

Symptom: The account shows a large remaining credit balance — reviewers report ~1,594 — but generation is refused and the app prompts an upgrade.
Cause: Credits are not the only meter. Tiers carry separate caps on concurrent jobs (1/2/3/4 from Free to Elite) and on per-tool volume — vectorizer exports, upscales and background removals each have their own plan ceiling, and reviewers describe hitting a monthly generation cap well beneath their credit balance, with some accounts dropped from a newer model version back to an older one. A credit balance is an entitlement to spend within those ceilings, not a right to spend it at all.
Solution: Read the plan's per-tool ceilings rather than the credit number and work out which one you've hit — vector exports are the usual answer. Because the homepage and /pricing disagree on those ceilings by up to 4x, check the counters in-account rather than on either marketing page. If a cap rather than credits is binding, upgrading buys ceiling, not credits — so price the upgrade against the number of vector exports still needed. Unspent credits don't survive a lapsed plan, so don't stockpile them.

"I used a free-tier logo for my business and someone says I don't own it"

Symptom: A logo generated on the free plan is already live on a site, invoices or packaging, and its licence is now in question.
Cause: They're right. The Terms state that if you are not a Paid Member you do not own the assets you create — Logo Diffusion instead grants a Creative Commons BY-NC (non-commercial, attribution) licence, which by its own terms doesn't permit commercial use and requires attribution. The clause names a nonexistent version ("4.1") while linking to the 4.0 legalcode, but the non-commercial restriction is unambiguous either way. Separately, free-tier generations are public and remixable by default, so the mark may already have been reused. A company over $1M revenue has a second problem: even a paid Basic or Pro seat doesn't confer ownership — only Elite or Enterprise does, per individual.
Solution: Stop using the free-tier mark commercially. Regenerate or re-export it under a qualifying paid plan so the ownership clause attaches, and keep the dated receipt showing which plan produced the file — the plan at generation time is what the clause turns on. If the company is over the revenue threshold, buy the Elite seat before treating the mark as owned. Then do the step no plan covers: clear the mark at USPTO/EUIPO and run a reverse-image search before spending on it, since ownership of a file is not a trademark, and purely AI-generated work is generally refused US copyright registration.

"I bought the AppSumo lifetime deal and I'm on the free plan with 40 credits"

Symptom: An AppSumo lifetime purchase grants far less than the tier advertised, credits don't renew monthly, and support tickets go unanswered.
Cause: This is the most-reported grievance about Logo Diffusion, not a one-account provisioning glitch — multiple reviewers describe receiving free-plan access at 40 credits that never renewed, and "not a single answer, not even an acknowledgement" from support. The deal is now sold out, so there's no live listing to redeem against, and the vendor's Terms publish no refund clause at all — the only mention of refunds is the statement that you won't get one.
Solution: Take it to AppSumo, not the vendor — AppSumo is the merchant of record, holds the transaction, and runs its own refund and dispute process, the only route with leverage here. File there with the deal page's advertised tier, the purchase receipt, and screenshots of the account showing actual entitlement. Post the same evidence on the deal's review thread; the vendor responds publicly more reliably than by ticket. If AppSumo's refund window has closed, a card chargeback citing goods-not-as-described is the remaining recourse — and don't buy further credits meanwhile, since that weakens the not-as-described claim.
