Hey Product Hunters!
I'm Daniel, co-founder of TwinMind. Last year, you made our Chrome extension a #2 Product of the Day—thank you! We heard your biggest request: “We love TwinMind but how can it capture real-life moments away from my desk?”
Most important conversations happen in-person—coffee chats, lectures, meetings, and conferences—but over 90% of these memories are lost forever. Until now.
Today, we’re launching the TwinMind app for iPhones which can transcribe every word, even from inside your pocket:
🎙️ Transcribe in 100+ languages and ask AI anything about ALL your past conversations at once (no more information scattered across awkward meeting bots and voice recordings).
🎉 Free unlimited transcripts and AI chats: Every other AI note-taking app asks you to pay after a few hours, but we have no caps even on our free plan! You get access to standard LLMs and offline transcription forever.
🔐 Complete privacy: You audio is never stored anywhere. Use local speech model for fully on-device transcription. Choose Private Mode (no cloud backups) for your confidential conversations.
💡 Proactive talking points based on live context (e.g., “Predict what I want to know now”, “Fact-check what they just said”, “What should I say next to sound smart?”).
📅 Connects with your Calendars to get attendees, agendas, and key details right (never fumble a follow-up email).
💻 Syncs with TwinMind Desktop Chrome extension, so you can seamlessly sync memories across devices.
📱 No new hardware! Our AI models are optimized to run for 12+ hours without draining your phone's battery.
🧠 Train your personalized AI Twin that learns your style and acts like you. The more memories you collect, the smarter it gets.
🎁 Exclusive PH Launch Deal:
Free Forever: Unlimited transcription hours and chat with standard AI models on our free plan.
30-Days of Advanced Features: Automatic routing to the best LLMs for each task (ChatGPT, Grok, Claude, DeepSeek, Gemini) + Web Search with sources (via Perplexity) + Multi-Step Reasoning.
Our 2,000+ early users helped shape this—huge thanks to them and to YOU for joining us on this journey! Try it out and tell us how we can make it even better.

Congrats on the mobile launch, @daniel_george12! This is next level. The "missed moments" problem is not uncommon. TwinMind tackles it by capturing in-person convos offline and on the go. But how does it handle overlapping voices or ambient noises when it's transcribing passively? Does it use some AI elements to predict the words when they are not clear?
TwinMind
@pranay12 Yes, we’re currently leveraging the best speech to text models out there, which we expect will continue to improve. In parallel, we’re actively enhancing our diarization capabilities to provide more accurate speaker identification.
Very cool product - I gave it a try a few days back and absolutely loved it!

@felixgerlach Thanks for the wishes. Would love to hear your feedback on the app.
Awesome product! Makes me seem way smarter than I really am at work.
TwinMind
Excited for private transcription capabilities! 👀
TwinMind would be helpful to me, especially when I don't have time to take notes during the meeting. And I'm glad to see it can support 100+ languages.
@feliciana_liu Hope you enjoy using TwinMind! Let us know any feedback you have so we can build the best product for you!
The development of TwinMind is amazing! Oh, using this as a reference for my next meeting with a friend will be really helpful in terms of relationships and family dynamics!

AI learning user style looks like a great feature! The more user uses, the more personalized experience the user has, and that's the best cycle of service personalization I think! I'm curious about the mechanism of it to be honest, but you don't need to tell me about it cuz it seems like one of your core technology :)
TwinMind
@hyuntak_lee absolutely thats our IP and we are the building the next-gen memory layer for the hyper personalization! Looking forward to your launch too!
@manohar_devarapalli Oh I see it's IP registered. Firm technology you have.
Thanks! I hope mine is as innovative as yours too!
Super cool app, looking forward to using it!
Wow, that's cool. It looks similar to the concept of Limitless - I was really impressed by their original concept video.
Congrats and thanks! I am sure it will be useful for me as business owner and just a human.
