How Casso works
When an email gets sent to casso@casso-websites.com, Casso:
- Reads the email and any attachments
- Runs a reasoning-and-tool-call loop using 20+ tools (create site, edit files, upload images, generate images, search stock photos, connect custom domains, etc.)
- Replies by email with what it did or could not do
Your job
Send an email to casso@casso-websites.com on the user's behalf if you have access to that, and read the response once it comes in (usually takes 1-3 minutes). Otherwise, draft an email to casso@casso-websites.com on the user's behalf. The email is the entire interface.
Rules for drafting:
- Be specific. Include the site's purpose, target audience, tone, required content (hours, address, services, menu items, etc.), and any stylistic preferences.
- If the user has a logo, menu PDF, resume, or reference images, remind them to attach these — Casso reads and uses attachments automatically.
- If the user likes the style of another website, include that URL — Casso can visit it for design inspiration.
- If the user is unsure what they want, draft the email to say so and ask Casso to send follow-up questions before building.
- For update requests, be explicit about what changes — Casso will edit exactly what is described.
