OpenBrainA place to think.
Write daily notes and project context directly. Rich text, selection formatting and autosave keep the writing flowing.
Your thoughts.
With somewhere to go.
A calm workspace for the human. A structured memory for the agent. Connected notes, projects, tasks and sources make both a little more useful.

Illustrative workspace with synthetic content.
THE HUMAN SIDERoom to think.
Room to think.
Tools to move forward.
A place to make progress.
Pin and order projects, choose icons and colors, and switch Card or List views. Subprojects and a compact Kanban or Next up list keep work focused.
A place to find it again.
Browse notes, sources, projects and images. Use collections to group notes and images, with image tags, details and fullscreen browsing.
Your next thought is close.
Press ⌘K to find notes, sources, projects, tasks and images. One contextual New dialog adds the next piece.
Answers with somewhere to point.
Ask your knowledge a question. Follow the evidence back to the original source, and keep the context behind an answer.
Your context travels with you.
A native SwiftUI iPhone app and a working private ChatGPT integration share the same records as the web workspace.
STRUCTURE WHEN IT HELPSA project.
A project.
Not a filing problem.
Start with the notes. Put the next tasks below. Give a piece of work its own subproject when it needs a separate focus.
Explicit project scope lets you view just this project or include its subprojects. Collections group notes and images across the work, without duplicating them.

IMAGES WITH CONTEXTMore than a pile
More than a pile
of thumbnails.
Browse project images and images from your notes in the shared Library. Add details and tags, group them in collections, and open a fullscreen viewer with keyboard navigation.
The image stays connected to where you use it. A project gallery is a useful view of your images—not another isolated bucket.
THE AGENT SIDEBring your AI.
Bring your AI.
Keep your context.
The private ChatGPT integration can find and work with your knowledge today. The same domain model powers web, iPhone, REST and both MCP transports.
Scoped, revocable identities, approval flows and version checks give agent work clear boundaries. Clients need configuration, and permissions decide what each identity can do.

UNDER THE HOODA vector database.
A vector database.
And the context around it.
Semantic search is part of the story. Reliable memory also needs original evidence, a shared data model, predictable writes and a way to inspect what changed.
Approved sources→Processing worker→PostgreSQL + pgvector→Web · iPhone · AI
Words and meaning.
1,536-dimensional embeddings with cosine similarity, PostgreSQL full-text search and GIN indexes. Hybrid ranking adds entity matches and recency to retrieve relevant context.
From source to knowledge.
A PostgreSQL-backed worker normalizes and processes captures. Validated AI outputs enrich the knowledge layer while preserving the original source and provenance IDs.
Keep the receipts.
Source-linked answers, revision history, export and Trash keep the record inspectable. Row-level security, scoped identities and version-conflict checks protect access and edits.
One model. Many doors.
Next.js web, native SwiftUI iPhone and thin MCP adapters use one shared REST and domain backend. Your notes and project state remain canonical across clients.
IN YOUR POCKETA native app.
A native app.
The same brain.
The SwiftUI iPhone app brings Today, Projects, Tasks, Library and Ask together. Edit rich notes, browse sources and images, search your workspace and pick up the next task.
It’s a private build, not an App Store release. Server operations need a connection; foreground and pull-to-refresh keep views current. It is not a full offline-sync client.
