Local-first
Audio and transcripts never leave your Mac.
Live todayWhy it works
Good prompts are long prompts. Context, constraints, examples. That's a lot of typing for a chat box. Penwright lets you brief the model the way you'd brief a person, in 30 seconds of talking.

Write a launch email for a productivity app. Audience: Mac power users. Tone: confident, not salesy. CTA: Download for Mac.
In the wild
Three moments in ChatGPT where Penwright pays for itself.
The quick reply
Press the hotkey, speak the reply, Penwright types it cleanly into the open ChatGPT window. Three seconds instead of three minutes.
The long-form message
Three minutes of speaking turn into a structured ChatGPT message, cleaned, with paragraphs, in the right tone. No typing cramp.
The recurring template
Save your ChatGPT standard replies as snippets, expand them by voice. The local dictionary learns your names, companies, acronyms.
Day one: setting Penwright up for ChatGPT.
- Install Penwright
macOS 13 or later. Grab the .dmg from the download page, drop it in Applications, open.
- Pick your hotkey
Default is ⌘⇧Space. If Spotlight is in the way, set a conflict-free shortcut right away.
- Seed your ChatGPT dictionary
Drop in the names, companies, codenames that show up in your daily ChatGPT threads. Penwright will get them right from day one.
- Dictate your first ChatGPT message
Open ChatGPT, click into a text field, hold the hotkey, speak. Release. The cleaned version lands in the field.
Frequently asked
- Does Penwright work in ChatGPT?
- Yes. Penwright types wherever your cursor lands in a text field, including ChatGPT. There's no separate ChatGPT integration; Penwright uses macOS' standard text insertion.
- Are my ChatGPT messages sent to the cloud?
- No. Transcription and cleanup run locally on your Mac (EuroLLM 1.7B with Metal). If you flip Settings → AI & Style to Claude or OpenAI, then yes, but only when you explicitly activate it, and a visible CLOUD badge stays on while it is.
- Does Penwright understand ChatGPT-specific jargon?
- Decent out of the box, perfect with your own dictionary. Add company names, people names, codenames once in Settings. Penwright will type them correctly into ChatGPT from that moment on.
- Do I need a fast internet connection?
- No. Once the models are installed, Penwright works offline. Ideal for travel, airports, long calls.
In ChatGPT, typing is the real tax.
Three to four times faster with voice. The math gets uncomfortable fast.
