One box for every thought. Search that finds what you meant. An AI that starts from what you wrote, and agents whose work waits for your approval. Notes, tasks, projects and people, in one open-source workspace.
One confirmation now, one sign-in link when your spot opens. Nothing else.
Why it exists
Good ideas end up split between a notes app that can't think and an AI chat that can't remember. Brain Portal keeps a durable copy of everything you capture, and gives the AI that copy to work from.
The product
Six parts of one workspace, built on the same records, so nothing is copied between apps.
Type, paste or dictate into the Brain Bar. It works out whether you wrote a task, a note, a reminder, a decision, a link or a question, and files it.
Notes are indexed by meaning as well as by words. Ask what you decided about pricing and get the note where you decided it.
Open a chat on any note, task or capture. The answer streams back already holding that item, its project, your highlights on it and your closest related notes.
Send a task, note or project to a background agent. The result arrives as a draft in your review queue, where you approve it, ask for changes or reject it.
People and companies are picked out of what you write, matched against who you already know, and given a timeline of every mention and every real conversation.
Tasks, projects and a daily operations view built on the same records. Health ratings always say why, and forecasts only appear when there is recent pace to base them on.
Highlight to instruct
Highlight a passage and the colour says what you want done with it. Every AI that later reads the note gets the same meanings, so a review answers your markup without you writing a prompt.
Try a colour. Each has a keyboard shortcut in the editor.
Our onboarding takes four screens. Most people quit on the second one, where we ask for a phone number. Removing it is the obvious fix.
Edit: Rework this, it's not right yet
Your AI, your rules
AI here is something you configure and can audit, not a black box bolted on.
Connect OpenRouter in one click, or paste an OpenAI or Claude key. The owner of an instance can also use their ChatGPT plan. Keys are encrypted at rest and never shown again.
Everyday jobs, deep analysis, image reading and search each get their own model, chosen from a live catalog. A retired model is skipped instead of breaking.
A usage log lists what each AI call was for, which model answered, the tokens it read and wrote, and whose key paid.
If your key fails, it says so. It moves on only to your own backup keys, and only to the server's key if you allowed that.
Write down your values, tone and boundaries once. Background agents read them on every job.
Works with your AI tools
A built-in Model Context Protocol server with 59 tools, 8 resources and 4 prompts, over local stdio or HTTPS. Your agents search what you wrote, save what you just decided, and read your day before they answer.
Each key has only the permissions you tick, its own rate limit and an optional expiry. Revoke it and it stops at once.

Everything else
All of it shipped and in the app today. Nothing on this list is a roadmap item.
Markdown editor
Markdown shortcuts, a toolbar that stays put on mobile, and a cursor that stays centred as you type.
Note lenses
See the same note as a chart, timeline, checklist or table. Rules pick the view and say why.
[[Wikilinks]]
Links between notes are recorded as connections in the background.
Spell check
On or off per device.
Board and calendar
Kanban board, day and week calendar, and a backlog to drag from.
Recurring tasks
Finishing one schedules the next.
Project trees
Projects inside projects, with health ratings and insights.
Collaborators
Invite editors and viewers to a project.
Intake triage
Loose captures get a suggested home with its reasons. Nothing is filed until you confirm, and every step can be undone.
One page a day
Ten entry categories, and a monthly compilation of the month's entries.
Nothing typed is lost
Entries are saved on your device first and sent when you are back online.
Attachments
Images, PDFs, Word, Excel and audio. Text is extracted, audio transcribed and images described, so all of it is searchable.
Large uploads
Big files go straight to storage instead of failing at a size limit.
Share with another account
Give someone on the same instance view or edit access. Remove them and access ends at once.
Public links
A read-only page for any note. Turn it off or issue a new link at any time.
Installable app
Add it to your home screen on a phone or computer.
Works offline
Pages you have opened stay readable. Notes, tasks and quick captures made offline sync when you reconnect.
Voice
Dictate in browsers that support speech input. Uploaded recordings are transcribed.
Email you can act on
Mark a task done or snooze a reminder straight from the email, with undo.
Needs you
The home screen leads with what is waiting on you, and shows nothing when nothing is.
Agent batches fold up
When an agent writes forty notes, your feed shows one line you can open, not forty rows.
Notifications
In-app and email: due dates, a daily digest and an optional weekly AI report.
It tells you when it breaks
Background failures show up in plain language, with a report you can copy to whoever runs the server.
Export
Download everything as a ZIP of Markdown files, Obsidian-compatible if you like.
Highlights travel
Exported highlights keep their meaning as text, since Markdown has no colour.
Trust
Every claim below links to the file that does it. A privacy page can say anything; source code has to run.

Straight answers
Better you hear it here than find it after you've moved your notes in.
No native mobile apps
It is an installable web app. It works on phones, but it is not in an app store.
Voice depends on your browser
Live dictation uses the browser's speech input, so it works in Chrome and Safari but not everywhere.
Meaning search covers notes
Notes are searched by meaning. Captures, tasks and files are found by their words.
AI is not free to run
AI features need a key: yours, or one the person running this instance provides. Their provider's data policy applies.
Early access
It is in active development (version 0.x). Things change, and some edges are rough.
How joining works
Leave your email. You'll get one confirmation, and nothing else until your spot is ready.
Spots are opened by hand, a few at a time. Your account is created then.
Use the emailed link, or type the six-digit code on any device. No password to set.
FAQ
You get one confirmation email. When your spot opens, your account is created and you get a second email with a sign-in link. Nothing else is sent to your address.
Yes. The full source is public under the AGPL-3.0 license. You need a database (Turso / libSQL), an email account to send sign-in links, and an AI key.
OpenRouter, OpenAI or Claude, with a model you choose for each job. You can connect your own key unless the person running this instance has turned personal keys off; without one, AI runs on the key they provide, if they allow it. A usage log shows every call.
Brain Portal does not train models. When an AI feature runs, the relevant text is sent to the AI provider that was connected, and that provider's data policy applies. If that matters to you, connect a provider whose policy you trust, or run it yourself.
Yes. Settings exports everything as a ZIP of Markdown files, readable in any editor and compatible with Obsidian.
Yes. It includes a Model Context Protocol (MCP) server, over local stdio or HTTPS, with keys you scope and can revoke.
