The AssinaJá assistants

There are two assistants inside AssinaJá, and neither needs installing or connecting: they are already there. One explains a document to you before you sign it; the other places the signature zones from a description you write.

Then there is a third route, which is the opposite one: instead of using the platform’s assistant, connect yours — Claude.ai or ChatGPT — and drive AssinaJá from the conversation you already have open.

Inside AssinaJá

Explain this document

On the signing screen, the Explain this document button opens the AI Reviews panel beside the document, where you ask whatever you like about what you are about to sign. You must be signed in, and once you have signed the conversation becomes read-only. Step by step in Ask questions about a document.

Auto AI — it places the zones for you

In step 3 of the sending wizard, the Auto AI tab places the signature zones from a description you write, and shows the plan — under I will apply — before it touches the document. It places zones; it does not send. Step by step in Prepare a document with AI.

What the two have in common

They spend from the same token balance, ask for the same acceptance, send the document text to an external AI provider, and neither signs nor sends — the detail is in AI on the platform.

Connect your own assistant

If you would rather work from Claude.ai or ChatGPT, AssinaJá runs an official MCP server: the assistant prepares documents, checks what is still unsigned and fetches the signed PDF, with the access of the API key you choose. What it is, and what it is never given, is in What MCP is.
