Own your thoughts. Choose your AI.
What’s the big idea?
A private home for every thought worth keeping.
Capture ideas, memories, reflections, questions, and the things you do not want to lose. Search them yourself, or let the AI assistant you already use help — only if you invite it in.
- Idea
A notebook that remembers for me — and lets an assistant help without owning any of it.
- Memory
The kitchen in the old flat, rain on the window, nobody in a hurry.
- Question
What would I work on if nobody was watching the numbers?
- Decision
Say no to the March contract. Protect the mornings.
Fictional samples. Your thoughts are never shown publicly.
Capture anything
Save an idea, memory, concern, reminder, or a note about your day without choosing a rigid format first. A thought can become structured later.
Find it later
Postgres full-text search across titles, content and summaries, plus tags, dates, collections, people, projects, and explicit relationships.
Private by design
Authentication is required, every row is isolated per account, and you can export or permanently delete everything you have stored.
Bring your own assistant
WTBI stores the memory. You choose the intelligence.
There is no model inside WTBI — no summarizer, no auto-tagger, no subscription to a provider you did not pick. Instead, WTBI can be connected to an assistant you already use. Add WTBI in ChatGPT or Claude, sign in once to approve it, and from then on you can ask your assistant to save a thought or find one — while the archive itself stays here, with you.
- An assistant gets a short list of actions — never the run of your account
- You decide what each connection may do: read only, or read and write
- Every action is written to an activity log only you can see
- Cut access off at any time; the thoughts stay exactly where they are
- Summaries and tags sit beside your words — your original text is never rewritten
