Flint vs AudioPen
Updated 11 September 2026 · Prices checked 11 September 2026
AudioPen takes a spoken ramble and hands back cleaned-up written text. Flint records, transcribes on your phone, and reformats the result into a structured note. The jobs overlap enough that people end up choosing between them.
The differences that actually decide it are the payment model, where the audio is processed, how long a single recording can be, and how many devices you want it on. This page goes through each one.

One payment against a renewal date
Flint is $11 to $16 depending on where you buy it, paid once. AudioPen Prime is $33 for three months, $99 for a year, or $159 for two years, which works out at $11.00, $8.25, and $6.63 a month respectively.
AudioPen's monthly rate is low, but it is a rate. Over two years the gap is roughly $159 against a single payment under $16. If you take one voice note a week, that gap is the whole decision.
Where your audio goes
Flint transcribes on the phone. The audio is not uploaded by default, and recording works with the network off entirely.
AudioPen sends the recording to its servers to transcribe and rewrite it. That is an ordinary trade for most notes and a hard stop for interviews under an NDA, clinical material, or anything covered by a confidentiality agreement.
The fifteen minute ceiling
AudioPen caps a single recording at 15 minutes. For its core use, talking through one idea, that is plenty.
It is not plenty for a lecture, a one hour interview, or a long call. Flint has no per recording cap, so length is the cleanest dividing line between the two: if your recordings routinely run past a quarter of an hour, AudioPen is not built for them.
Tidy prose against a structured note
AudioPen's output is a cleaned-up version of what you said, in prose, with a few style options. It is good prose.
Flint's output is a note: a summary, a list of key points, or a format you define yourself and reuse every time. If you want the same seven headings on every client call, that is a Flint job. If you want one tidy paragraph out of a two minute ramble, AudioPen does it better.
Platform reach is AudioPen's win, and it is not close
AudioPen runs on iOS, Android, Chrome, Mac, and Windows. You can capture a thought from whichever machine you happen to be at.
Flint is a phone app. There is no desktop app and no web app, so if half your thinking happens at a laptop, Flint simply is not there for it. This is the strongest reason to pick AudioPen instead.
Which one should you pick?
It runs in Chrome and on Mac and Windows. Flint has no desktop or web app at all, so half your captures would have nowhere to go.
Rewriting loose speech into clean prose is the job it was built for, and it does it better than a note formatter does.
AudioPen caps a single recording at 15 minutes. Flint has no per recording limit, so lectures and hour long interviews still work.
Transcription happens on the phone and audio is not uploaded by default. AudioPen processes every recording on its servers.
One payment of $11 to $16 against AudioPen's $99 a year, or $159 for two years.
You can define your own output format and reuse it. AudioPen gives you tidy prose with a few styles, not a template you control.
Record it once, keep it forever.
Flint records, transcribes on device, and formats the result into a note. One payment, no subscription, no account required.
