Every AI tool starts from zero — it knows everything public and nothing about you. ThoughtStack is your personal context layer: capture your thinking once, and every tool you use answers with your context, in your voice.

Capture anything
Forward an email, save it straight from a chat, or jot it in the app. Two seconds, wherever the thought happens.
It compounds
ThoughtStack distils what you save into connected insights. The more you add, the sharper your context gets.
Use it everywhere
Connect once via MCP. Claude, ChatGPT, Cursor — every tool you use answers with what you know.
Under the hood: everything you capture is distilled into connected, searchable context — private to you, owned by you.
Stop re-explaining yourself
Every new chat starts cold. With ThoughtStack connected, your tools already know your positions, your projects, and how you think.
Write like you, at scale
Our LinkedIn app drafts posts from your actual ideas, in your actual voice — not generic AI filler that sounds like everyone else.
Resurface what you forgot
That sharp observation from two years ago shows up exactly when it becomes relevant again. Your past thinking keeps working for you.
Not locked inside one chatbot's memory. Not training someone else's model. A context layer you own and carry with you — to every tool, and whatever comes after them.
