What Taac actually does
An AI-native notes app for the Mac. The whole point: you can talk to your own notes, and none of it leaves the machine.Everything runs on-device — chat, semantic search, meeting transcription. No API keys, no account, no Ollama to install first. It looks at the Mac, picks models that fit, and downloads them in the background.Answers cite the notes they came from, so you can jump straight to the source instead of trusting a summary.1. Note editor — rich text and raw Markdown2. Spaces — up to five, fully isolated

Why Taac
AI is genuinely useful for your notes. Today you just get to pick your poison.
Poison 1
The convenient way
Cloud AI note apps send everything you write to someone else's servers. Your journal, your meeting notes, your half-formed ideas — all uploaded, logged, and used to train who-knows-what.
Poison 2
The private way
Running AI locally today means wrestling with terminals, Ollama, model files and API configs just to ask a question. Great if you're an engineer with a weekend to spare. Useless for everyone else.
Taac
Both, actually
Download the app, click the features you want, and the models install themselves in the background. That's it. No cloud, no command line, no compromise — and Taac is tuned to run on a normal Mac, not a $5,000 workstation.
Proof, not a promise
Your notes and recordings never leave your device.
Every model — chat, search, transcription, summarization — runs locally on your Mac. Your notes stay on your filesystem as plain Markdown. Take Taac on a plane and it still works.
The only two times Taac uses the network
- Downloading the AI models, once, up front.
- The auto-updater checking GitHub for new versions.
Neither one sends a single word of your notes anywhere — but I'm not going to claim “zero network” when that isn't literally true.
Features
Five things Taac does, all on your machine.
Keep scrolling — they come one at a time.
01Chat with your notes
02Search by meaning
03Meeting notes, on-device

Search by meaning, not keywords
Searching “vacation plans” finds your note about a trip to Italy — even though it never says “vacation.” Try it on eight sample notes:

Type to search your notes
03record
Meeting notes, on-device
Record a call — mic plus system audio, so Zoom, Teams and Meet all work. Taac transcribes it, tells speakers apart, and writes a clean summary with checkable action items, all offline. Live transcription on Apple Silicon; switch to “media” mode for lectures.
04markdown
A writing experience you'll actually like
A rich Markdown editor with a live WYSIWYG mode and a raw-Markdown mode, one click apart. Images, code blocks with syntax highlighting for ~25 languages, links, lists — and it auto-saves as you type.
05spaces
Organized the way you think
Up to five fully isolated Spaces — work, personal, a side project — each with its own name and icon. Nest notes in folders, drag & drop to reorganize, and open several notes at once in tabs.

Zero-setup AI
Taac installs its own brain, and picks one that fits your Mac.
Most local-AI tools hand you a shopping list of models and a terminal. Taac detects your hardware and picks the right models automatically — hiding anything that won't run well. Pick the features you want and everything downloads in the background, with progress you can pause and resume. No Ollama. No API keys. No config files.

roadmapConsolidation & bug-fixing
Polish and stability.
Windows release
Same app, more machines.
Linux release
Right after Windows.
Sync across your devices
Open-source and self-hostable, up in one click.
Mobile companion app
Your notes in your pocket, synced privately.
AI-powered to-do lists
Turn notes and meetings into things that get done.
Sync is self-hostable on purpose — syncing your devices shouldn't mean handing your notes to us.
Before you download
Taac just hit 1.0. Here's where the rough edges are.
Taac is young, so expect the occasional bug.
This is the first release and it's under active development. If something crashes or freezes, that's not you doing it wrong — it's early software. Open an issue; it's the fastest way to get it fixed.
The first indexing can be slow.
Import a big pile of notes and Taac has to index all of them for semantic search. After that it’s incremental — only changed notes get re-indexed, in the background — so you never wait like that again.
“Offline” has two exceptions.
Downloading the models needs a connection, once, and the auto-updater pings GitHub for new versions. Neither ever sends your notes anywhere.
Yes, Taac is an Electron app.
I built Taac on a stack I know well and can support properly, instead of chasing a lighter one I'd be learning as I went. In daily use I haven't hit memory issues — but if you do, tell me right away.
FAQ
The questions everyone asks.
Taac is a free, open-source note-taking app for macOS with AI built in. You can chat with your notes, search them by meaning and turn recorded meetings into summaries — and every one of those models runs on your own Mac rather than in the cloud. Notes are stored as plain Markdown files on your filesystem.
No. Chat, search, transcription, speaker detection and summaries all run locally on your Mac, and your notes are stored on your own filesystem. Taac works with your Wi-Fi off — the only time it talks to the network is to download AI models and check for app updates.
No. There is no terminal, no config file and no account to create. You download the app, click the features you want, and the models install themselves in the background. If you can install a Mac app, you can use Taac.
None of them. Taac ships its own inference stack and downloads its models itself, in the background, the first time you enable a feature. There is nothing to install alongside it and no key to paste — if you can install a Mac app, you have done the whole setup.
An Apple Silicon Mac (M1 or newer) with 16 GB of RAM, on macOS 14+. Taac detects your hardware and picks models that run well on it — no guesswork.
Yes and yes. Taac is free and open source under the AGPL-3.0 license.
Chat runs on Qwen3.5 4B. Semantic search uses EmbeddingGemma 300M with a Qwen3 reranker. Meeting notes use Whisper and Qwen3-ASR with speaker diarization. Taac picks the size of each model to match your Mac, and you can delete any of them later.
On disk, you only download what you use: Chat is ~2.7 GB, Smart Search ~0.9 GB, and Meeting Notes is optional (~0.5–2.5 GB depending on quality). You can delete any model you no longer need. RAM is handled for you — Taac loads a model only while a feature is actually running and unloads it as soon as you are done, so an idle Taac is a notes app, not a few gigabytes sitting in memory. It also picks model sizes that fit your Mac in the first place.
Obsidian keeps your notes local but leaves the AI to plugins and your own API keys. Notion AI is the opposite trade: excellent AI, and every word you write goes to their servers. Apple Notes has neither the AI nor the Markdown. Taac is the combination — local Markdown files, AI that works out of the box, and nothing uploaded. It imports from Apple Notes, Obsidian and Joplin if you want to move.
Yes. Taac records the microphone and system audio together, so any call playing through your Mac is captured — Zoom, Teams, Meet or anything else. It then transcribes the recording on-device, separates the speakers, and writes a summary with action items. The audio is never uploaded.
Yes — Taac imports from Apple Notes, Obsidian and Joplin, with a preview before anything is added to a space.
Not yet — Taac is macOS-only today. Windows and Linux are next on the roadmap.
Yes. Once your models are downloaded, everything works with no internet connection.
