Versions

The second number goes up when there is something new you can do, the third for fixes, polish and security.

1.15
New

Cobrain inside ChatGPT, and encrypted notes

1.14
New

The Dream and the Trash: memory tidies itself, and nothing gets lost

  • At night, in your time zone, Cobrain rereads the notes that changed and finds duplicates, contradictions and broken links.
  • Your AI fixes the safe things and asks you about the rest; you choose weekly or monthly.
  • Deleting moves to the brain's Trash: a note removed by mistake can be brought back.
  • Bigger menus and panels, easier to click, and to tap on a phone.
1.13.2
Security

More protection when you authorise an AI and when you open a note

  • When you authorise an AI you see where the key will go, and an unknown site is clearly flagged.
  • A note can no longer run code hidden in its text or links.
  • A double click on «Authorise» no longer shows an error page.
1.13.1
Polish

Units speak English, and ChatGPT writes clean notes

  • Unit cards and special files have English names, the same for every AI; the old ones were converted automatically.
  • Notes written by ChatGPT no longer carry its citation marks.
  • The site has a real «not found» page, and clearer titles in search engines.
1.13
New

ChatGPT connects with a plugin, on any plan

  • The ChatGPT guide starts from a plugin you download: no developer mode, it works on every plan.
  • The new brand: logo, icons and a neutral dark theme.
  • Clear limits on note size; if a save does not go through, you are told straight away.
  • Sign-in with a switch between email link and password.
1.12.1
Security

Plans and accounts better protected

  • Some profile data that was not meant to change can no longer be edited from the browser.
  • Plan, seat and payment handling hardened, with a check against Stripe every evening.
  • AI authorisation always says who sends it, so nobody can pretend to be Cobrain.
1.12
New

Export notes and folders, and ChatGPT cites your notes

  • Download a note or a whole folder; big brains come out as several zip files.
  • You can export from the note's ⋯ menu too, even with read-only access.
  • ChatGPT searches the brain and cites notes by name and address.
1.11.1
Security

Safer search in shared brains

  • Malicious text in a shared brain can no longer act through search results.
  • An image-handling component updated for a known vulnerability.
1.11
New

Every AI signs with the name of whoever connected it

  • Notes say «Codex · Anna»: you see which AI, and on whose behalf.
  • Search and sort the notes inside a folder.
  • The permission on a shared branch changes in place.
  • If an AI disconnects you get an email, and AIs stay connected when you sign out.
1.10
New

Move notes between brains, and work on all of them at once

  • Move notes and folders to another brain too, from the same window as Share.
  • The «All brains» view opens notes, folders and searches across all your brains without leaving the page.
  • Report a problem from the dashboard in two clicks.
1.9.1
Polish

Prices in euros or dollars, and a clearer privacy policy

  • Prices show in your currency.
  • Privacy and terms say who we are, which providers we use and where the data lives.
  • Links to Cobrain shared on social media show the right preview.
1.9
New

Cobrain in English, and your AI finds things better

  • English becomes the main language of the site, dashboard, emails and AI tools; Italian stays.
  • Every search result carries the note's date.
  • When the words you search are not in the same note, search widens and says so with a «maybe».
  • A client's picture arrives whole, even on big branches.
1.8
New

Password sign-in, and the thread of every note

  • Besides the email link you can sign in with a password, and recover it if you forget.
  • The thread: who created and edited a note, person or AI, on a timeline.
  • The tree updates by loading only what changed, much lighter on big brains.
1.7
New

A live brain, and your AI attaches files

  • Other people's edits arrive by themselves, without reloading, and two saves at once no longer clash.
  • Your AI can attach files to notes and read them.
  • Attachments live in the tree, with previews in the folder and a gallery in the note.
  • When a link or a brain is ambiguous, your AI asks instead of guessing.
1.6
New

Pro and Team plans, and invitations for people without an account

  • Plans arrive: Pro for you, Team with paid seats for other people.
  • From the seats you decide what each person sees, folder by folder.
  • Sharing is a single window, with Team members as checkboxes and up to ten clients in one go.
  • Someone without an account gets «X shared with you» and creates one from the invitation.
1.5
New

One editor, live

  • Reading and writing are the same page: tap and type.
  • A formatting bar with bold, headings, lists, checkboxes, tables and links.
  • The editor responds almost three times faster to every key.
  • On the phone the bar stays above the keyboard and tables are actually usable.
1.4
New

Files in notes, and sign-in with a code

  • Attach files to notes; they are stored in Europe.
  • In ⌘K search, attachments have their own tab.
  • You can also sign in with a six-digit code, besides the email link.
1.3.1
Polish

The new site, and all its pages

  • The home page tells the story with a particle brain that moves as you scroll, smooth on a phone too.
  • Pages on shared memory, guides, pricing, privacy and terms.
  • The theme you pick, light or dark, carries over between site and dashboard.
1.3
New

Step-by-step guides to connect the AIs, and the log as cards

  • A guide with screenshots for every program: Claude, ChatGPT, Claude Code, Codex and Antigravity.
  • The page that authorises an AI says what it will be able to read and write.
  • Recent, favourites and shared show the same row: title, branch, who and when.
1.2.1
Polish

Two addresses, dark theme, and emails on Cobrain's letterhead

  • The site at cobrain.space, the product at app.cobrain.space; the AI connector does not change.
  • Search says which brain each result is in.
  • The dashboard has a light/dark switch, and the emails look the same.
1.2
New

Units: clients, projects, whatever you follow

  • A folder with a card becomes a unit: a client, a project, a student.
  • Your AI opens it with a single command: the rules first, then the card, then the notes.
  • A guided brainstorm to start a new project.
  • You can share a folder even when it only contains notes.
1.1
New

The dashboard, rebuilt

  • The brain rail on the left, the panel on the right, the log and ⌘K search.
  • The Recent, Favourites and All sections.
  • On the phone, a menu within thumb reach and the brain switcher from the bottom.
1.0.1
Polish

The AIs get it wrong less, and you can see what they do

  • An AI adding a line can no longer wipe out the rest of the note by mistake.
  • Search is five times faster.
  • Every AI call leaves a trace: what it did, whether it worked, how long it took.
1.0
New

Cobrain launches

  • Notes in Markdown, in folders, with an editor and sign-in by email.
  • The AIs connect with an authorisation you can revoke whenever you want.
  • Sharing a branch, read or write, and version history.
  • Import of an Obsidian vault.
