# Binderwork

> Share decks with page-by-page analytics, send documents for e-signature and hire your first people, in the app or by asking ChatGPT or Claude. Free and open source under AGPL-3.0, hosted or on your own server.

Binderwork is the AI-native, open-source alternative to DocuSign and DocSend, and to Ashby for a startup's first hires. It is free and open source (AGPL-3.0-or-later): hosted at https://app.binderwork.com, or on your own server. It covers deck sharing with page-by-page analytics, email gates, watermarks and data rooms (instead of DocSend), e-signatures with signing order, templates, bulk send, reminders and sealed, timestamped PDFs with a certificate of completion (instead of DocuSign), hiring with a careers page, a pipeline board and offers signed in the same place (instead of Ashby), Y Combinator's post-money SAFE, closing a round, the SAFE register, the cap table and employee paperwork.

It works from ChatGPT, Claude, Claude Code, Cursor and VS Code through one MCP server, from a CLI and over REST. Anything that reaches another person (a link, an envelope, a SAFE) waits for a person to approve it in Binderwork; an assistant cannot send it alone.

## FAQ

### Can it really replace DocuSign and DocSend?

For a startup's everyday work, yes: decks shared with page-by-page analytics, email gates, watermarks and data rooms, and documents signed with signing order, templates, bulk send, reminders and a sealed certificate of completion. DocuSign and DocSend do more for large companies, such as qualified electronic signatures, CRM integrations and enterprise compliance programs; each comparison page lists where they are better.

### Is it really free?

Yes. The software is open source under AGPL-3.0 with every feature in it, and hosted Binderwork is free, with what that includes written down on the pricing page. Binderwork never charges a fee tied to a signature, a closed round or a share transfer.

### Are the signatures legally binding?

Binderwork follows the evidence practices of the US ESIGN Act and UETA: consent to sign electronically, an explicit Sign step, a seal with a timestamp that shows any later change, and a full audit trail. In the EU these are simple electronic signatures. Some documents, such as wills, can't be signed electronically at all. This is not legal advice.

### Do investors and signers need an account?

No. Readers open the link in their browser, after giving or confirming their email if you ask for it. Signers sign on a phone or a laptop without signing up.

### What does my assistant see, and can it send things on its own?

It sees what it asks Binderwork for while you chat, such as a document's title, who read it or who has signed. Anything that reaches another person waits for your tap in Binderwork. Binderwork itself doesn't send your documents to an AI model, and nothing you upload trains one.

### Can I run it myself?

Yes, that is the point of the license: it runs on one Linux server with Postgres, and LibreOffice for Word files. The source opens to everyone with the first public release; until then, hosted Binderwork is free and every record exports in open formats.
