Parlin vs Superwhisper. Both local. One is paid once.
Parlin and Superwhisper both turn speech into text on your Mac instead of on a server, which is why people compare them. The differences are what happens after transcription and how you pay: Parlin bundles an on-device cleanup model, meeting notes with speaker labels, live translation, and link transcription for $39 once; Superwhisper charges a subscription, with a lifetime option, and its AI cleanup runs through an API key you bring from OpenAI, Anthropic, or Groq.
Where they are the same
Both apps listen when you hold a key, transcribe on the Mac's own chip, and paste the result into whatever app has the cursor. Both work offline once their speech models are downloaded. Both transcribe audio files. If your only need is private push-to-talk dictation, either one does the job, and you should pick on price and on what else you want from the app.
Where they differ
Cleanup is the first fork. Raw transcription gives you 'um so I think we should uh ship it monday'. Cleanup turns that into a sentence. Parlin downloads a small language model once and runs it on the Mac's GPU, so cleanup is on-device and included. Superwhisper's AI modes call a cloud model through your own API key, which means an account with a provider, usage billing on top of the subscription, and your text leaving the Mac for that step.
The second fork is scope. Parlin records meetings and produces speaker-labeled notes, a summary, and action items; translates as you talk; and turns a YouTube, Instagram, or TikTok link into a transcript you can caption or remix. Superwhisper is focused on dictation and file transcription.
The third is billing. Parlin is one purchase that covers every update to version 1 and up to three of your own Macs. Superwhisper is a monthly or yearly subscription, or a lifetime tier, and any AI cleanup adds provider usage fees. Prices change, so check both sites the day you decide.
Who should pick Superwhisper
If you already pay for an OpenAI or Anthropic API key and want cleanup from a large cloud model rather than a small local one, Superwhisper's approach may suit you. It has been in the market longer and has a wide set of community modes. If you prefer to rent software month to month, that is also a fair reason.
Who should pick Parlin
If you want the whole voice workflow on one Mac with nothing to configure and nothing recurring: dictation into any app, cleanup that never leaves the machine, meeting notes, translation, and link transcription. Parlin's English engine scores about 98% on clear speech in the published LibriSpeech benchmark and returns text in roughly 0.2 seconds; the numbers and the models are on the technical details page.
