Sparkle: AI Dictation Keyboard

Sparkle is a voice-to-text keyboard that runs entirely on your device. No internet. No cloud. No subscription. What you say stays on your phone.

PAUSE TO THINK
Most dictation cuts you off after one second of silence. Sparkle waits. Take a breath. Collect your thoughts. It's still listening.

BUILT FOR LONG PROMPTS
Dictate into Gemini, Claude, Perplexity, or any AI app. Stop typing essays with your thumbs. Speak your thoughts, then send.

KEEPS YOUR HEADPHONES QUIET
Other apps pipe ambient noise through your AirPods while you dictate. Sparkle uses your iPhone's mic directly. Your noise cancellation stays on, no weird echo.

WORKS EVERYWHERE
Messages, Notes, Email, Slack, WhatsApp, Notion, Obsidian. If it has a keyboard, Sparkle works there.

ONE BUTTON
That's the whole interface. Tap to record, tap to stop. No menus, no modes, no confusion. Swipe left to delete words. Swipe right for Enter.

NO TIME LIMITS
Speak for as long as you need. Sparkle transcribes in chunks as you go, saving each piece to disk immediately. No "recording limit reached" nonsense.

NEVER LOSE A WORD
Phone call interrupts? Saved. Siri pops up? Saved. App crashes? Saved. Your last 20 transcriptions are backed up to History. We built a 5-layer safety net because losing a 20-minute voice memo is unacceptable.

WORKS IN BACKGROUND
Switch apps while transcribing. Check a reference. Copy a link. The mic keeps running. Designed to stay active in the background.

TWO MODELS
Fast (English only) at 147MB. Multilingual at 632MB with 99 languages. Models download once from Apple's servers, then work offline forever.

PRIVATE BY DESIGN
No accounts. No analytics. No tracking. Processing happens on-device using Apple's Neural Engine. We literally cannot see your transcriptions.
