Hey Product Hunt — Josh from OpenWhispr here 👋
OpenWhispr is on iPhone and iPad, and today we’re bringing it to Product Hunt.
It’s 100% open source, with local models that let you transcribe on your device for free, without usage limits or an account.
Right now, you can:
• Write with your voice in any app
• Draft messages with your voice assistant
• Adjust your writing’s tone to match your vibe
• Record and transcribe conversations
• Sync your notes with desktop on Pro
• Choose on-device transcription, OpenWhispr Cloud or your own API key for supported workflows
Already on Pro? Just sign in. Mobile is included. On-device transcription stays free and unlimited; the voice assistant uses Cloud or your own API key.
For the developers here: on-device transcription uses NVIDIA’s Parakeet through FluidAudio and Apple’s Core ML and Neural Engine, plus OpenAI’s Whisper through whisper.rn/whisper.cpp. The app chooses the engine based on your selected languages and downloaded models.
Speaker labeling runs locally too. Saved voice profiles help recognise familiar speakers across recordings: strong matches get a name automatically, while uncertain matches become suggestions you can confirm. The profiles and matching stay on your device.
Give it a try and tell us what works, what doesn’t, or what you’d like us to add. We’re here to improve it with you.
Thanks for being early,
Josh and the OpenWhispr team
Josh, leaving uncertain speaker matches for someone to confirm is a nice detail. A wrong name in a transcript can be harder to notice than a wrong word. Congrats on the iOS launch!
@oleksii_sekundant Appreciate it! Let me know if you need any help setting it up!
Congrats on the iOS launch, Josh! Nice to be launching alongside you today. We're launching Benson too: https://www.producthunt.com/products/benson-2. Would appreciate a comment or some support if you've got time today. Hope it's a great launch day!
Ive been using Openwhispr a lot on my linux and I absolutely love it, excited to see it come to my Iphone!!
@anas_chhilif love to here it! Give it a try and let me know what you think :)
Loving this, what model would you suggest for best accuracy on M4 Max chip machine but without having to start noisy fans
@suki_buildz Thanks Suki! On an M4 Max I'd run:
Dictation: Cohere Transcribe 2B, our most accurate local model. Pick your language instead of Auto, because Auto means English. If you want something lighter, Orukeet is close behind.
For meetings: I would use the same Cohere model, and pick your meeting language before you record. For long recordings you can try Parakeet Unified EN (or Orukeet for other European languages).
Cleanup + voice assistant: Gemma 4 26B MoE, with "Keep model loaded" on. Use the same model in every tab.
Ooh, does this work if you switch languages mid-sentence?
@chrissylim Yes! We have Parakeet v3, which supports switching. It’s worth trying, though accuracy when switching mid-sentence can vary. I would recommend Cloud with auto-detect. Let me know if you need help setting it up!
