I think we should restructure the API to support batch operations — it'll make the mobile client much faster.
Features

Built for how you think.

No friction. No setup. A tool that gets out of the way and lets you speak.

01

Floating pill, always ready

A minimal capsule that floats above every window. No dock icon, no menubar clutter — just a single hotkey away whenever you need it.

02

Three recording modes

Toggle, hold-to-record, or re-paste last. Fully rebindable — tune it to how your brain works.

⌥Space Toggle recording
⌥R Hold to record
⌥V Re-paste last
03

Auto-paste, zero interruption

Crisper captures which app you were in before recording. When done, it pastes directly back — Slack, Notion, VS Code, anywhere.

04

Full transcript library

Every recording saved with its source app, timestamp, and word count. Search, filter, pin, replay — your personal voice archive.

Two-stage AI polish

Crisper's speech model transcribes with unmatched accuracy. A local Crisper model then fixes grammar, removes filler words, and makes it sound intentional.

06

Audio playback with scrubbing

Replay any recording with an interactive waveform. Scrub to any point, compare what you said to what was transcribed.

07

Fully customizable hotkeys

Visual key-capture UI. Record any combination, changes take effect immediately. No app restart required.

How it works

From thought to text in seconds.

The entire pipeline runs on your Mac. Fast, private, and invisible.

01 — Speak

Press and speak

Hit ⌥Space or hold ⌥R. The waveform confirms you're being heard. Say anything — notes, emails, code comments.

02 — Transcribe

On-device transcription

Crisper's speech model runs entirely on your Mac via CoreML, converting audio to raw text with state-of-the-art accuracy.

AI refines the text

Crisper's on-device language model cleans up the raw transcript — grammar, filler words, repetitions — while preserving your voice.
