Content stays on your Mac
Dictation, transcripts, meeting audio and local indexes are processed and stored on your machine.
Included at launchWhy it works
Slack rewards short messages because typing is expensive. With Penwright, that economics flips: the response that would have taken three messages becomes one well-formed reply, complete with bullet points and the right tone for the channel.

okay so my take on the launch is we should push it a week because the docs arent ready and we havent run the migration on staging yet

My take on the launch: push it a week. Two reasons. The docs aren't ready, and we haven't run the migration on staging yet.
In the wild
Three moments in Slack where Penwright pays for itself.
The quick one
Click into a Slack text field, hit the hotkey, speak. The clean text is in before you would have typed it.
The long one
Three minutes of speaking become structured text with paragraphs and punctuation. No typing cramp, no reformatting.
The recurring one
Standard replies live as snippets and expand from a spoken trigger. The dictionary keeps names, companies and acronyms spelled right.
Day one: setting Penwright up for Slack.
- Install Penwright
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 dictionary
Drop in the names, companies and codenames you use every day. Penwright will get them right from day one.
- Dictate your first Slack message
Open Slack, click into a text field, hold the hotkey, speak. Release. The cleaned version lands in the field.
Frequently asked
- Does Penwright work in Slack?
- Yes. Penwright types wherever your cursor lands in a text field, including Slack. There's no separate Slack integration; Penwright uses macOS' standard text insertion.
- Are my Slack messages sent to the cloud?
- No. Transcription and cleanup run locally on your Mac, Metal-accelerated. If you add your own Claude or OpenAI key in Settings, then yes, but only when you explicitly activate it, and a visible CLOUD badge stays on while it is.
- Does Penwright understand Slack-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 Slack 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 Slack, typing is the real tax.
Three to four times faster with voice. The math gets uncomfortable fast.

Privacy
Privacy by architecture, not by policy.
Penwright does not need your spoken content to provide the product. Audio, transcripts and local indexes stay on your Mac, and you can verify the network traffic yourself.
Data minimisation by default
Penwright's servers handle accounts, licences and billing, not the audio or transcripts you create on your Mac.
Included at launchNo audio or text upload endpoint
The Penwright API has no route for your dictation audio or transcripts. A server cannot leak content it never receives.
Included at launchVerify every claim
Use any network monitor you trust. The security page documents the traffic you should, and should not, see.
