The Best AI Note Taker Apps for Your Phone
Some of the most important conversations happen away from a laptop: a client lunch, a site visit, a hallway decision. The right phone app turns them into notes as reliably as a video call.

The best AI note taker app for iPhone and Android in 2026 is Hedy. It records in-person conversations on either platform, shows live coaching on the phone or an Apple Watch, and on recent iPhones and capable Android phones can run the whole AI pipeline on the device. Otter.ai is the most established cloud option, Circleback has the most generous free plan, TwinMind is built for all-day capture, and Plaud is the pick if you would rather carry a dedicated recorder.
We ranked apps that run natively on both iPhone and Android and can record an in-person conversation with the phone's microphone, then judged them on what you get afterwards: transcript quality in a noisy room, how quickly notes arrive, whether anything works without signal, and what the free plan really allows. Tools whose mobile app only plays back meetings recorded elsewhere are excluded, as is Fathom, whose phone app has been announced but has not shipped.
Hedy
Editor's Pick On-DeviceAI meeting coach with full on-device AI and real-time intelligence
The only meeting assistant among the 28 we tested with a built-in option to run its entire AI pipeline (transcription, summaries, and real-time coaching) on-device on supported hardware, making it the privacy and reliability leader for 2026.
Otter.ai
CloudReal-time transcription and agentic meeting AI for teams
A powerful, increasingly agentic cloud platform for teams who prioritize collaboration and live AI over on-device privacy.
Circleback
CloudMeeting notes with or without a bot, unusually clean action items, and deep automation hooks
One of the best-executed notetakers in the mid-market, with excellent transcription and action items, and now a real free plan and a $15 entry price to prove it on.
TwinMind
CloudAI second brain that captures and remembers your conversations
A fast-improving second-brain app with strong transcription and bot-free capture on phone and desktop, held back mainly by cloud-dependent AI and thin integrations.
Plaud.ai
HardwareAI voice recorder hardware with a full software platform
Once an in-person-only recorder, Plaud has grown into a capable hardware-plus-software platform with a desktop app, an AI agent, and a Team plan, though its AI still runs in the cloud.

Recording From Your Phone, Done Right
In-person audio is harder than a video call. A Zoom call hands the notetaker a clean, separate audio stream. A café table hands it clattering cups, cross-talk, and a speaker two metres away. Place the phone flat in the middle of the table with the microphone unobstructed, and expect speaker labels to be less reliable than on a call. Every app on this list does better with a short test in the room you will actually use.
Battery and signal are the practical limits. A two-hour workshop on cellular data can drain a phone and still leave you waiting for the upload. Apps that transcribe on the device avoid the upload entirely. Hedy's Local AI runs on iPhone 15 Pro and newer and on Android phones with a supported GPU and about 8 GB of memory, so the recap can be ready before you leave the building. TwinMind falls back to a smaller on-device transcription model without signal. For a dedicated device that never competes with your phone's battery, Plaud's recorders are the alternative, though they need a paid or device-linked plan to transcribe.
A phone on the table is not consent. In-person recording feels informal, which is exactly why it causes trouble. Several US states, including California, require everyone's agreement to record a confidential conversation, and under GDPR one participant's consent never covers the others. Say you are recording, and say what the notes will be used for. Our guide to in-person notetakers covers the etiquette in more detail.
