An assistant that waits for your yes

Ask Cynco Assistant in plain words. It reads your books, uses the same code the app uses, and prepares any change for you to approve or reject before it's saved.

Guardrails

Some things always wait for a person

Recording a payment, making or reversing a journal adjustment, finalising an invoice, matching the bank and closing a period always wait for your approval. No setting, key or mode lets the assistant skip that.

  • Pending, approved, rejected, executed or failed
  • Once you approve, the result shows up in the chat

Your own AI

Bring the AI you already use

Run cynco mcp serve and every command in Cynco's CLI becomes a tool for Claude Desktop, Cursor or any MCP client. Each key can do only what you allow.

  • Permissions such as invoicing:read and accounting:read
  • API and MCP keys on Pro

The details

Skills
Instructions you write in markdown, up to five active at once. A skill tells the assistant how you like things done. It never lets it do more.
Models
Runs on Cloudflare Workers AI, falling back to a second and third model if the first fails.
Credits
Free starts with 100, Pro includes 250 a month, Enterprise is unlimited. Categorising a bank line or sending a reminder never uses them.
Retries
If a change is retried, Cynco returns the saved result instead of making the change twice.
The record
Every run is saved with its cost, tokens (how much text the AI processed) and time taken, and every step with the tool used, what it was given and what came back.
