BrrainyA second brain that
actually thinks.
Brrainy remembers everything you work on and gives it back to every AI you use.

As of nowKeep pricing usage-based through the beta cohort. This supersedes the older annual-first launch note; the original remains linked as historical context.
Why this exists
You keep explaining
yourself to software.
You told it on Tuesday. In a different thread, in a different tool. But nothing you said survived the closed tab — so tomorrow you type it all again.
The models keep getting smarter. The forgetting never got fixed.
We ship the beta on Friday.
Pricing stays usage-based.
Priya owns the launch checklist.
Do not touch the billing migration.
“Sorry — remind me what you’re working on and what you decided?”
How it works
Never explain yourself twice.
You do not organise anything. You do not search for anything. It just keeps up.
While you work
Everything, connected
One memory underneath it all.
Your apps and assistants send what happens. Brrainy sends back the context they need. You never move anything by hand.
Ask anything
Answers with receipts.
Ask in plain language. Watch it search your actual sources and answer from them — never from a guess.

What you get
It comes to you.
No dashboard to check. No search box to remember to use.
You wake up already caught up.
A short brief written overnight from everything that moved yesterday - decisions, risks, and the one thing to do next.
Today needs three decisions
Pricing stays usage-based through the beta cohort. The older annual-first note is preserved as superseded context.
Launch risk remains ownership: two beta tasks still have no assignee before Friday's review.
Next move: send the investor update after the launch owners are confirmed.
Wherever you think
It is already where you are.
Five ways in, plus 26 apps that sync themselves. You never open a “memory app” — it meets you where the thought happened.
Capture without leaving what you are doing.
One hotkey, anywhere on your Mac. It also watches your clipboard and folders, so the things you never stop to save get saved anyway.

One assistant’s memory
Why not just leave it there?
An assistant can remember its own chats. Brrainy is the memory those chats, agents, and your own key share.
Across assistants
Capture includes chats from other assistants, and ambient capture on the desktop.
Same memory for agents
Agents connect through MCP into that same space-scoped memory.
Your key
A wallet, and you can bring your own key. Plans are Free, Pro, Team, Pro Plus, and Enterprise.
Questions
Straight answers.
What is Brrainy?
Brrainy is a memory layer that works across every AI assistant you use. It captures what you work on, strips the noise, organises it into your own space, and gives it back when it is relevant - so you stop re-explaining yourself to every new chat.
How do I keep my context when I switch between ChatGPT and Claude?
One memory, read by every assistant. The browser extension captures conversations automatically from ChatGPT, Claude, Gemini, Perplexity, DeepSeek and Grok, and because the MCP server is hosted over HTTP, any MCP-capable assistant or agent connects to that same memory. Switching models stops costing you your context, because the context never lived inside the model.
How is this different from ChatGPT's built-in memory?
ChatGPT's memory works inside ChatGPT. It does not travel to Claude or Gemini, and you cannot take it with you. Built-in memory is free and needs no setup, which Brrainy does not match - you connect your sources first. What you get for that is one memory every assistant reads, that stays yours when you change tools.
Can I use my own OpenAI or Anthropic API key?
Yes, on every plan including Free. Bring-your-own-key is honoured across all five paid operations - chat, embeddings, reranking, OCR and speech-to-text - not chat alone. Indexing a large corpus is the expensive part, and that is the part most tools keep billing for.
Can my AI agents read the same memory?
Yes, over MCP. There are exactly two tools, brain_recall and brain_remember, so an agent can look something up or write something back without a sprawling API surface. Humans and agents read the same space-scoped memory.
Humans and agents.
One memory. Your rules.
Stop re-explaining yourself to software. Start compounding what you already know.
Kept separate
Personal stays personal. Work stays at work.
Your own key
Bring your own AI key, or just use ours.
