JompterAn OpenWhispr alternative built around your coding agent.
OpenWhispr is open-source dictation with local or cloud models, meeting notes and AI chat, on more platforms than we cover. Jompter is narrower on purpose: it builds the prompt a coding agent needs — your words, your screen and your screen recording — on your Mac.
Free for 7 days · up to 10,000 words · no card · Apple Silicon, macOS Ventura+
Dictation gives you words. Coding agents need context.
Prompts, not just text.
Your words land in the prompt with the screenshot you took mid-sentence and the screen recording of the bug — one Markdown prompt your coding agent reads for itself.
Your agent reads it directly.
Jompter's MCP server hands prompts, screenshots and to-dos to Claude Code, Cursor, Codex and OpenCode — no copy and paste.
It sees what you see.
Box, point at or blur part of a screenshot before it's sent, or record the flicker and let Jompter keep the key frames with your transcript.
Context that persists.
Plans keep the error, the screenshots and what you tried, so the follow-up is one line added — not the whole story re-explained.

Speak the bug. Snap the screen. Paste one prompt.
Your words, the annotated screenshot and the key frames from a recording land in one Markdown prompt, ready for Claude Code, Cursor or ChatGPT.
- Voice, on-device. Whisper, Parakeet and Nemotron transcribe on Apple Silicon — no audio leaves your Mac.
- Screens, redacted. Annotate with pen, arrow, box, text or blur before anything is shared.
- Copied in one click. Markdown and images together, straight into your agent.
