- Graph — on a shared graph, collaborators' cursors and selection rings move live on the canvas, the same way Whiteboard already worked.
- Database — the header now shows the avatar stack when others are viewing the same record, completing the fleet-wide presence rollout.
- Apps — switching to Spanish in Settings → Language now updates chrome in twelve apps live (no restart): Code editor, Browser, Preview, Chat, Agent, Contacts, Mailbox, Books, Theme editor, Form designer, Automations, and Files.
Previous releases
-
Live presence avatars now show in Tasks, Chat, Journal, Calendar events, Graph, Code editor, Preview, and Books — plus browser tab fixes and Settings polish.
-
Live presence — when you share a board or a note, you now see your collaborators' cursors and avatars in real time. Plus a per-site trust switch for the in-app browser and an instant light/dark shell.
-
A task or event reminder now fires even if the app wasn't running when it came due — it catches up the next time you open Brainstorm. Plus a fix for list numbers going missing in composers.
-
Removing someone really removes them: when you take a collaborator off a shared note, page, or channel, they can no longer read anything you write afterward — access removal is now enforced by encryption, not just policy. Plus a PDF crash fix.
-
Small fixes on the back of the sharing release: your own name shows up instead of "Anonymous", a couple of rough edges smoothed, and a fix for a harmless console error in Tasks.
-
Invite teammates to any note or collection, give them Editor or Viewer access, and edit together — changes sync live, end-to-end encrypted, with the relay never seeing your content. Viewers are now truly read-only.
-
A quality release: task and calendar reminders now fire even when the app is closed, duplicate alerts are gone, synced attachments can be cleaned up server-side, and every known dependency vulnerability is patched.
-
Semantic search arrives — an on-device model finds your notes by meaning, not just keywords. Plus a background-activity center, six new dashboard widgets, a richer chat composer with @-mentions, and editor templates.
-
A fixes release for the public beta — status and select cells now edit as a type-or-pick list, the calendar and preview render cleanly, chat messages stay out of the file browsers, and the assistant shows real titles instead of internal ids.
-
A polish release for the public beta — the PDF viewer now fits the page on open, text fields and buttons line up on one control scale across apps, and the entity inspector reads as a tidy property sheet.
-
The first public beta of Brainstorm — a local-first desktop where your apps, your files, and your AI all run on your own machine, with optional end-to-end encrypted sync across devices.
