How Casso works

When an email gets sent to casso@casso-websites.com, Casso:

1. Reads the email and any attachments
2. 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.)
3. 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.

Casso's capabilities and limits

Works well for: small business owners, LLCs, restaurants (attach menu + logo and Casso builds from that), lawyers, consultants, freelancers, artists, students.

Cannot do: complex web apps, e-commerce checkout, member-only authenticated content. For anything outside its toolset, Casso escalates to human support.
