Quickstart
Go from zero to your first AI-powered document edit in 5 minutes.1. Create an account
Sign up at use.superdocs.app with Google or email/password. Free plan includes 500 operations per month — an operation is one AI request that modifies, analyzes, or searches a document (uploads/parsing and exports are free; very large edits count one operation per 25 sections changed). Full definition and examples: Plans & Usage.2. Create an API key
- Click the gear icon in the app to open Settings
- Go to the API Keys tab
- Click Create API Key and give it a name
- Copy the key immediately — it’s only shown once

Building an autonomous agent? You can skip the UI entirely. One call to
POST /v1/agents/signup returns a working key with no human in the loop. See For AI Agents.3. Make your first request
You choose the
session_id. It’s any string you pick, not a value the server assigns or returns. There’s no “create session” call: the first request that uses a new string starts that session, and reusing the same string continues it. Pick something stable per document or per user (e.g. user_123_draft-contract). See Sessions.4. Read the response
response— The AI’s reply explaining what it diddocument_changes.updated_html— The full updated document HTML. Render this in your editor.usage— How many operations you’ve used this month
5. Continue the conversation
Reuse the samesession_id to keep editing. The server keeps your document between turns, so on a follow-up you send just the message. No need to re-send document_html:
When to re-send
document_html: only when you changed the HTML outside of chat. For example, the user edited the document in your own editor and you want the AI to see those edits. Then send the full current HTML (exactly as your editor has it, data-chunk-id attributes intact) and it replaces the server’s copy. If chat is the only thing touching the document, omit document_html on every turn after the first. See Documents.Next steps
