Types into the apps you already use. No plugin, no extension, nothing to configure.
Three keys.
One voice workspace.
Speak anywhere on your Mac. One key types what you say, one answers from what you have told Tyne, and one turns a spoken coding task into a prompt your agent can run. All three run on-device, in whatever app has focus.
Fn
Dictate
Hold Fn and talk. Parakeet transcribes on your Mac, S1-mini fixes punctuation, fillers and self-corrections, and the finished text is pasted once at your cursor.
⌥ Space
Ask Tyne
Ask a question, say “log it” to file a thought, or edit the text you have selected. Answers come from your encrypted Vault, filed under the right project.
⌥ ⇧ Space
Speak to Prompt
Describe a coding task out loud. Project Brain adds what Tyne remembers about the repo and compiles a prompt for Claude, Codex or Cursor.
Your second brain isn't a messy folder of files.
It’s a structured database.
Forget nested folders of loose Markdown files. Tyne keeps what you say, log and decide in one SQLCipher database, vault.enc, encrypted with a 256-bit key held in your Keychain. It is indexed for full-text search and entity lookup, and organised by project.
Screen & Circle context
Optional local window OCR (auto-purged after 15 days) plus Circle to Search to ask about any selected region on screen.
Project Brain & Vault
Decisions, constraints, and notes filed per project inside vault.enc, powering Ask Tyne and Speak to Prompt.
Meeting intelligence
Whisper Large Turbo + SpeakerKit transcribe microphone, system audio, or both on your Mac with speaker labels and action items. No bot joins.
Why use Tyne?
It types what you say, remembers all of it, and acts on it, without anything leaving your Mac.
Fn key
Hold it, speak, let go. Finished text lands at your cursor.
Every app
Mail, Slack, Notion, Xcode, Terminal. No plugin, no extension.
Ask your past
Ask about anything you have logged, decided or said in a meeting. A local model answers from your encrypted Vault without leaving the app you are in.
⌥ Space
“What tolerance did Marcus specify?”
→ ±0.05 mm
AES-256
SQLCipher vault with a 256-bit key in your Keychain. We can’t read it, and neither can anyone else without your Mac.
Action, not just text
Say “remind me to push the build at 5” or “book a sync with Sarah”. Tyne drafts the Calendar event or Reminder, and nothing happens until you approve it.
→ Calendar · Reminders
It cleans up after you
Filler and false starts are gone before the text lands. Variable names, file paths and flags come through exactly as you meant them.
Um, so, merge fixAuthFlow on Tuesday, no, Thursday.
No screen required
Talk through AirPods while you walk. A soft chime means Tyne is listening, and the pill shows where your words went.

Transparent when cloud-assisted.
Your voice is transcribed on your Mac, cleanup runs on a local model, and your Vault database stays on your disk. Choose strict Local Only mode or Balanced cloud synthesis.
Raw audio never leaves your Mac
Parakeet-TDT (dictation) and Whisper Large Turbo + SpeakerKit (meetings) run on Apple Silicon. Audio is never uploaded in any mode.
One encrypted SQLCipher vault
Notes, Atlas documents, and search indexes live in vault.enc and encrypted local blobs. The 256-bit key stays in your macOS Keychain.
Local Only vs Balanced mode
In Local Only mode (Free, Plus, or toggled on Turbo), S1-mini and Loom 3B handle everything offline. In Balanced mode on Turbo, only the text excerpts, anonymized web query, or selected screen region needed for a specific Ask/Atlas/Circle request are sent through our zero-retention gateway.
