Your typing, amplified.
WriteAmp reads what you've typed and predicts what comes next — as inline ghost text in any app. Press Tab to accept.
Type. Predict. Accept.
Three keystrokes separate a thought from a sentence. WriteAmp finishes the thought — you decide what to keep.
Type naturally
Keep typing in any app — Notes, Mail, Slack, VS Code, anywhere. WriteAmp watches in the background, locally, with no lag.
See the suggestion
After a brief pause, the next few words appear in subtle gray ghost text right at your cursor. No popup, no interruption.
Tab to accept
Press Tab for the next word, ` for the whole thing. Esc to dismiss. Or just keep typing — it goes away.
Adapts to where you write.
WriteAmp detects which app you're in and adjusts the tone automatically. Mail gets formal sentences. Slack stays casual. Code stays verbatim. You can override per-app once and it remembers.
- Auto-detects Mail, Slack, Notes, VS Code, Terminal, and 20+ apps
- Per-app profiles for max words, stop sequences, insertion mode
- You stay in flow — WriteAmp picks the right voice

yeah sounds good, lets do

Encrypted on-device, capped at 100 sessions, opt-in
Learns the words you actually use.
Opt-in personalization extracts the names, code terms, and phrases you type often, then quietly injects them into suggestions. Encrypted with AES-GCM, capped at 100 sessions, and deletable with one click.
- Bigrams, trigrams, named entities — all encrypted with a Keychain key
- Off by default — you turn it on, you turn it off, no questions asked
- 100 session cap prevents unbounded growth

Your keystrokes never leave.
No cloud. No analytics. No model calls. No telemetry. The model runs on your Mac's GPU, your text stays in your apps, and WriteAmp doesn't even have a server to phone home to.
Encrypted history
Personalization data is AES-GCM encrypted with a Keychain-stored key, on disk and at rest.
No tracking
Zero analytics SDKs, zero crash reporting, zero "phone home". You can verify with a network sniffer.
No cloud sync
No account. No login. No sync. Your settings live in ~/Library/Application Support/WriteAmp/.
On-device inference
A 270M model running on Apple Silicon GPU completes 80-120 tokens/sec. No server round-trip.
"It's the first autocomplete that actually feels like autocomplete should — invisible until you need it, then obvious in hindsight."
