What makes mybrain different
A brain that knows you - not a chatbot that forgets.
Compounds automatically
mybrain only learns what's genuinely new. Every conversation adds to a growing knowledge graph — no duplicates, no noise. The longer you use it, the more precisely it knows you.
Your knowledge, your data
Upload documents, share context, connect your tools. Everything you teach mybrain lives in your personal vault - encrypted, searchable, and yours forever. Export it anytime.
Switch models, keep your memory
GPT, Claude, Gemini, Grok, DeepSeek. mybrain works with all of them. Your memory and context travel with you no matter which model you're using.
The brain that grows
Value that compounds over time.
Every conversation leaves a trace. Every document adds context. The longer you use mybrain, the more it knows about you.
Tell mybrain your name, your job, your goals. It captures everything and starts building your personal map.
mybrain starts detecting patterns. It notices what you care about, who matters, and what's missing - and asks one smart question to fill the gap.
The knowledge graph deepens. mybrain tracks how your world changes — when facts evolve, old ones are superseded not forgotten. Synthesis surfaces patterns across everything you've shared.
An irreplaceable thinking partner. It knows who matters most, what's changed, and what gaps still exist — and keeps getting sharper without you doing anything extra.
Always up to date

The brain that improves itself.
mybrain only extracts what’s genuinely new. No duplicates. No noise. A knowledge graph that compounds with precision — automatically, with zero effort from you.
Daily Synthesis
Connects dots across your vault, converts recurring patterns into concept nodes, and persists insights into the knowledge graph permanently.
Gap Detection
It knows what it doesn't know. mybrain identifies missing context about people and projects - and fills the gaps over time.
Proactive Context
When something is missing, mybrain asks one targeted question at the right moment. Like a colleague who actually pays attention.
Key Truth Elevation
Facts that appear repeatedly across your conversations get elevated as “Key Truths” - they appear as gold nodes in your brain graph and are weighted more heavily in every chat. The things you care about most rise to the top, automatically.
Control & Privacy
Not locked into any provider.
Your brain vault is your memory layer. It's encrypted, exportable, and designed to stay separate from whichever model you're using. We don't train on your data - ever.
Dedicated instance
Your brain runs on its own server, completely isolated from every other user.
Encrypted at rest
All stored data is encrypted. Your memories, your documents, your API keys.
Zero training
Your conversations never touch a training pipeline. We don't learn from your data.
Export anytime
Download your entire brain as an Obsidian vault whenever you want. No lock-in.

Managed infrastructure.
mybrain isn't a wrapper around a chat API. It's managed personal AI infrastructure - a dedicated instance per user, permanent storage, and a memory system that compounds over time.
Dedicated AI instance per user
You don't share compute with anyone. Your brain runs on its own isolated Fly.io machine - your data never touches another user's environment.
16 models, one memory
Switch between GPT, Claude, Gemini, Grok, Llama, Mistral, and more mid-conversation. Your context and memory carry across every model switch.
Obsidian-compatible vault
Your brain is stored as structured markdown in Cloudflare R2 — scoped to your user ID. Permanently yours.
Automatic knowledge extraction
After every conversation, an LLM pass extracts facts, people, projects, and decisions - adding them to your graph without you lifting a finger.
Daily brain synthesis
Once a day, mybrain reads everything it knows and generates new insights, detects knowledge gaps, and identifies key truths - automatically making the graph richer.
Proactive Context
mybrain notices what it doesn't know and asks one targeted question at the right moment - like a colleague who pays attention. Toggle on or off in Settings.
App connections with memory
Connect Gmail, Calendar, and more. Each integration adds real nodes to your brain - contacts, events, topics - and syncs as you use those apps.
Developer API
Every memory in your brain is queryable via REST API. Ask questions, add facts, search by semantic similarity. Build apps on top of your own intelligence.
