Work, learn, live. All smoother. TomTrove is a personal assistant built on your own notes: in any app, select what you don't get to explain it, polish what you wrote with one key, and turn meeting notes into minutes. It works from what you gave it, and shows which notes it used.
Making sense of an email or wording a reply well should take seconds.
The result appears right in the app you're in. No need to explain the background: it looks in your knowledge base and shows which notes it used.
No switching windows, no pasting text into a chat box to ask again.

They need the quote by Thursday and sound a bit rushed. Reply today.

Select a message someone sent you: see what it means, the tone, what they want, and a few suggested replies.

Write what you want to say and press once. Pick natural, formal or casual, and it replaces your text in place.

Clipboard history, quick replies and your notes. Search, press Return, and it pastes. Clipboard history works without an account.

Lease · clause 7: give 30 days' written notice to move out.
Explain, polish and plugins pick the few relevant notes from your knowledge base each time. What isn't there doesn't get invented.
Write a note, paste a long text and have it split, add a web link or a PDF / Word / Markdown file, or just drag it into the Mac window.
When your knowledge base is used, the result lists which notes, so you can check.
When an old and a new note cover the same thing, the newer one is used.
Who you are, who you talk to, the tone you like, and rules like "no exclamation marks with clients". Polish follows them.
Plugins add actions below your explain and polish results. Install them from the Plugin Store in the Mac app; before installing, you see exactly what data each one can read.

TomTrove reads your notes to be useful, so here is exactly where they go.
Your account and notes are stored on Hetzner servers in Nuremberg, Germany. The model that searches your knowledge base runs on that same server, not with a third party.
When you explain or polish, only the selected text and the few relevant notes are sent to the AI providers (xAI, Microsoft Azure OpenAI). Never sold, never used for ads.
Passwords, card numbers and keys are masked before anything is saved, and replaced with placeholders before the AI sees them.
Before installing, you see what data a plugin can read, such as the selected text, relevant notes or About me. Anything not listed is off limits.
Delete any note in your knowledge base and turn clipboard sync off. To delete your whole account, email us and it's done within 30 days.

No switching windows, no copy and paste: select in the app you're in, press one key, and drop the result right back. It also knows your notes, shows which ones it used, and doesn't invent what isn't there.
