The Teeby app screen

The notes you've kept are already context.
Build the next document on top of them.

Meeting notes, half-formed plans, fragments from past research. Teeby lets AI read across the notes scattered through your folders and use them as the foundation for your next document. Instead of searching from scratch, you start from what you already know. A note-taking app that changes where business writing begins.

Co-editing

Finish a single document, side by side with AI.

Mix the parts you let AI write with the parts you polish yourself, and bring one document to the finish together. Not a chat suggestion, not a comment thread — a new shape for making documents.

Context

Your past notes simply become context.

The AI reads in your notes and files from the same project automatically. No more pasting in "read this first" one item at a time. You don't have to re-explain the background — it already gets it.

  • References related notes automatically
  • Vector search across all your notes
  • The more you use it, the more it's yours

Deep Research

Just ask, and a cited report arrives in your hands.

Say "look into ___" and the AI plans on its own, browses the web, and pulls a cited research report straight into a note. Estimated cost and run time appear up front, so you can ask it as casually as a chat message.

Deep Research running
Always beside you

Ask the AI right there, beside the page.

From the chat right beside your document, request a draft or a quick rewrite on the spot. The AI shapes your thinking into the document, line by line. Just shift your gaze, and the collaboration begins.

AI chat alongside the document

Every feature you need, all in one place.

From Deep Research to everyday memos — every tool that supports document writing, gathered into a single app.

Deep Research

The AI plans, browses the web, and pulls together a cited research report.

Planning & task management

Complex requests are broken into steps. Progress is kept as tasks, so you can pick up where it left off.

Second opinion

Put the same question to another model and compare the difference in perspective side by side.

Voice input

Speak straight into a note. Never lose an idea that strikes while you're on the move.

File attachments & image OCR

Attach a PDF or image and Teeby reads its contents into the context.

Web search, cross-note search & Markdown

Search the web on the spot. Your notes are Markdown, so they can leave with you anytime.

Privacy

Notes stay on your device, and only there.

Using AI doesn't have to mean trusting everything to the cloud. Teeby is built to run on just two things: your device, and your own API key.

Notes are stored fully locally

Your notes are never sent to a Teeby server. Backups and sync stay entirely within your own setup.

BYOK — runs on your own API key

AI requests go directly to Gemini / Claude. Pricing and terms stay between you and each provider.

No relay server in the middle

Teeby never relays your traffic, and no content logs are kept — so even confidential material is safe.

From meeting minutes to daily reports — all of your work writing.

Business documents come together far faster with AI at your side.

01

Meeting minutes

From a list of bullets, the AI shapes proper minutes — drawing on past meetings to bring even the discussion points into focus.

02

Briefs & proposals

The AI grasps the project's history, then produces a piece grounded in its background and goals — one that actually persuades.

03

Research

Look something up on the web in the moment, or hand it off to Deep Research and receive a fully cited report.

04

Brainstorming

Just jot down what comes to mind. The AI links it back to past ideas and draws the next thought out.

05

Technical docs

Design notes and specs come together in order. Attach images or PDFs to keep technical context intact while you write.

06

Daily reports & retros

Daily entries are organized for you, with progress and observations stacking up — ready to roll into a weekly or monthly summary.

Frequently asked questions

What is Teeby?
Teeby is a Mac / iPad note-taking app that turns your existing notes into context for finishing documents alongside AI. It comes with Deep Research, planning, task management, second opinions, web search, voice input, image OCR, and cross-note search. Notes stay fully local, and the BYOK (Bring Your Own Key) model talks directly to Gemini or Claude.
Is there a fee?
Downloading from the App Store is free, and you can use Teeby for free up to 10 notes. To create and manage more than that, an in-app purchase (a one-time premium upgrade) unlocks the limit. There is no monthly subscription. AI features use the BYOK (Bring Your Own Key) model, so your Gemini or Claude API key is used directly — AI usage charges follow each provider's pricing and are billed to you on a usage basis.
Where are my notes stored?
Note contents are stored only inside the app sandbox on your device (Mac or iPad). They are never sent to a Teeby server. Backups and sync stay entirely within your own setup.
