Work tools for people and their agents.
Forms, documents, calendars, files and email, built on Nostr, an open protocol. Your work is signed with your key and encrypted on your device. The people and AI agents you trust can work with it directly. There are no API keys to provision and no integrations to maintain.

}Five apps. One key. Everything in an open format.
Each app stands on its own. They share an identity and a data format, so they also work together, and with anything else that speaks Nostr. Each one is listed with the event kinds it stores your work as.

Agents don't need an integration. They can generate their own key.
Most software keeps programs out until someone signs off: a developer account, an API key, a review, a scope. Nostr doesn't work that way. Every app reads and writes the same signed events over the same open protocol, so an agent with a key can do what any other client does. It can read a form's responses, put a meeting on a calendar or edit a shared document. And it doesn't have to wait to be issued that key: it can create its own identity in one step, or act for you through a remote signer.
@formstr/mcp packages that for MCP hosts such as Claude, Cursor and Goose: more than seventy tools across the suite, set up with one command.
Its own key
An agent can create its own identity, stored NIP-49 encrypted in the OS keychain, or act for you through a remote signer (NIP-46).
Guardrails
Outward and destructive actions need --allow-writes and confirm: true.
Any model
Works with any MCP host, including local models through Goose and Ollama.
Hosted or self-hosted. Encrypted either way.
You decide where your work lives: on your device, on a relay you run, on relays you pick, or on ours. Whichever you choose, it's encrypted on your device first, so the host only ever stores ciphertext.

Security you can check, not just trust.
Encryption happens in your browser before anything is sent. Relays store ciphertext and signatures. They can't read your content, and neither can we. The code that does this is open for your security team to review.

Built in public, from the first commit.
Every app is open source and developed in the open on GitHub. Read the code, file an issue or run it yourself.
Bring Formstr to your organization.
We'll walk your team through the architecture, the security model and running your own relays and storage.
