Workspace
A workspace is a Matrix room. Members of the room are collaborators.
Sign in to Matrix
Uses matrix-js-sdk loaded from the browser. Credentials are kept in this device's local storage only.
Need an account? Sign up at hyphae.social.
PROVeo endpoint
Backend webhook handles redaction, Archive.org upload, and Matrix media sync.
You'll be asked per-upload; this just sets the default.
Claude API
Powers Chat answers grounded in your sources and the per-claim Research button. The key is stored only in this browser's localStorage and sent directly to api.anthropic.com with anthropic-dangerous-direct-browser-access. Web search, the system message, and per-source toggles live in the right-hand panel of the Chat tab.
Chat memory
When a passphrase is set, your live chat is encrypted and persisted in this browser's localStorage so it survives reload. The passphrase never leaves this device. Leave blank to keep chat in memory only.
Offline / local only
Keep working without Matrix. Log and sources stay in this browser.
Signed in as
Pick a Matrix room to use as this workspace. Anything saved here can be synced to the room as encrypted events.
Loading rooms…
Active workspace:
Invite by Matrix ID (e.g. @bob:hyphae.social). They'll see the invite in their Matrix client and can accept to join this workspace room.
Or share an invite link. Anyone with the link can sign in (or sign up at hyphae.social) and join this workspace.
For collaborators without a Matrix account:
  1. Open the invite link.
  2. Sign up for a free Matrix account at hyphae.social.
  3. Return to the link and sign in — the workspace will join automatically.
Establishing key…
Optional: set a shared passphrase for this room. The passphrase never leaves your device — every member must type the same string. This overrides auto-key sharing and protects against a malicious homeserver that could otherwise see the auto-exchanged key.
You've been invited to a workspace
Workspace:
Already have a Matrix account?
Sign in below — we'll join the workspace room for you automatically.
No Matrix account yet?
A Matrix account is a federated identity — one account can join workspaces on any Matrix server. Hyphae runs the recommended server for PROVeo collaborators.
Sign up in three steps:
  1. Open hyphae.social/register and create an account.
  2. Verify your email if prompted.
  3. Come back here, sign in with your new @you:hyphae.social credentials, and you'll join the workspace.

    Claude web research
    Claude proposes corroborating evidence from the live web. Each candidate is snapshotted to Archive.org before it enters the review queue — you approve before it binds to the claim.
    Claim under research
    Stored only in this browser's localStorage. Sent directly to api.anthropic.com with anthropic-dangerous-direct-browser-access.
    Archived snapshots are permanent on Archive.org. Approve the proposal in the review queue to bind it to the claim.
