Sealed by default
Vocert assembles each recording from verifiable parts — hashed, chained and signed the instant it's written, then transcribed and triaged automatically.

From a consent-aware record screen to sealed, reviewable evidence — here's exactly what Vocert looks like. Drag the slider or use the arrows.
Trusted when it counts
No setup, no stealth. Open the app, get consent, and tap record — Vocert handles the rest, and so far people love it.
The timestamped highlights are wild — I found the one sentence that mattered in seconds instead of scrubbing an hour of audio.
Finally a recorder where I can actually show the file wasn't edited. The signed receipt sold me.
Started a recording from my Apple Watch in a meeting and it just appeared on my phone. Felt like magic.
The consent prompt knowing my region's rules is a really thoughtful touch. It nudges you to do it right.
Speaker-labeled transcripts out of the box. I read the conversation instead of replaying it five times.
Calm, clean, dark UI. It doesn't feel like a creepy spy app — which is exactly the point.
Re-transcribing an old import gave me a cleaner result months later. The original audio never changed though — love that.
Free to start and genuinely useful on day one. Hard to beat that.
The hash chain breaking if anything's altered is exactly the guarantee I wanted from a recorder.
How it works
Four things Vocert does the instant you hit record — so the file holds up when you need it to.
Every chunk is hashed, chained and signed — alter one second and the whole chain breaks.
Speaker-labeled, searchable transcripts come back automatically — read, don't scrub.
Timestamped observations — threats, coercion, fraud — surfaced as flags, never conclusions.
Start on your wrist, finish on your phone — a recording is always one tap away.
03:48 — flagged observation, tap to inspect the sealed span.
