An Always-On AI Notetaker? This Startup Thinks You Can Just Use Your Phone

The show floors of CES 2026 are awash with AI-powered notetaking and companion devices that listen to everything around you so you can go back and have a computer remember a conversation you just had. The folks at Thine think somebody else already got the hardware right, and all they need to give you is the app.

Pratyush Rai, the CEO of Thine, said in an interview that he decided to create an app for Apple’s iPhone because the functions he would’ve needed to create a device, like a pin, a ring or a necklace, already existed in the phone’s microphone and Siri functions.

“What we have realized is we should not try to solve a problem both from a hardware standpoint and a privacy standpoint that Apple has already solved for,” he said.

The iPhone streams live audio while it waits for you to say “Hey Siri,” and Thine uses that same function to capture and transcribe the conversations you have. Its microphone also has very good noise cancellation — something a new hardware company would have to work to perfect on its own.

From there, Thine takes over, training an AI model on those transcripts so you can ask questions like, “What did that AI executive tell me the other day at CES?” It will respond like a typical chatbot would, with a summary of that conversation. At CES, I watched as Rai asked Thine to recall the conversation we first had about the app two weeks earlier, and it provided accurate and pretty thorough highlights.

Rai said Thine doesn’t store the audio recordings of your conversations. The exact transcripts aren’t available right now, but the company is working on a new version that will provide those transcripts and allow you to upload them into your own chatbot, kind of like if you ran the Voice Memos app all the time and just kept the transcriptions. Rai said the decision to allow people to access verbatim transcripts came after feedback from users of competing AI notetaking devices, who said they really wanted the actual transcriptions. 

For now, a fully functional Thine app is an expensive subscription: $200 per month. Rai said the target audience is executives and tech founders who want to keep track of all of their networking conversations. But he expects prices to come down significantly with scale, including as the AI models and software improve. Already, he said, those improvements allow the company to prepare the version that just offers transcriptions for around a dollar a month. 

The big expense remains long-term storage — and keeping it secure. Rai said having those old conversations accessible by the AI model is essential to reduce hallucinations, when AI makes stuff up to fill the gaps in its context. When you’re trying to recall conversations you actually had with real people, you don’t want the AI’s best guess at what you talked about. You need the truth. 

Being able to get that is key to Rai’s goal of creating an AI tool that helps you have better connections not with the chatbot, but with other people. He doesn’t want people to build relationships with Thine, but with each other. “This is not something we ever imagine with Thine,” he said.
