Atomic Presence
In the face of deepfakes and malicious edits, defend your authenticity with a cryptographic hash chain and digital signatures.
Works offline
Atomic Presence is a technical defense tool for interviewees, journalists, and legal evidence scenarios, centred on giving video and audio verifiable integrity.
In the deepfake era, verifiable authenticity is what’s actually scarce#
Lowering the barrier to video and audio production is mostly a good thing. The problem is that fabrication, re-editing, and context-stripping get cheaper at the same time, so “I recorded it” has drifted away from “I can prove this is how it really happened.” Atomic Presence steps into that gap: it lets you start building a verifiable evidence chain the moment you hit record.
The situations it’s designed for are the ones where you’d worry about the footage being challenged later: interviews, witness accounts, whistleblowing, contested scenes, any context where a recording might get disputed, re-cut, or forged. Casual everyday capture sits outside its target.
How it differs from ordinary recording tools#
Most recording tools think “record the file first, worry about preservation later.” Atomic Presence weaves hash chains, dynamic QR codes, and digital signatures into the capture flow while it’s happening. Verifiability is the core of the product from the start, not a patch bolted on afterwards.
That makes it feel more like a technical defense tool for risk scenarios. You may not reach for it every day, but when you do need it, you’ll want it already installed, with a workflow you already know, rather than scrambling to assemble tools in the moment.
Why four protection levels: different risks, different costs#
The protection levels correspond to real scenario differences. Sometimes you only need to signal “this is being recorded” to the other party; sometimes you need something closer to evidence-grade integrity verification. Having intermediate steps lets the tool sit inside actual workflows instead of offering only a crude on/off switch.
For journalists, legal professionals, citizen journalists, and anyone who regularly needs a clean record of a conversation, this is valuable. What helps them is a recording tool with fewer ambiguous zones; more filters and beauty modes won’t.
Privacy and offline are part of credibility#
A tool that claims to stand for authenticity loses credibility if its core data handling depends heavily on external servers. Atomic Presence keeps the critical computation on-device, partly for privacy and partly to reduce external dependencies inside the evidence chain itself. The fewer third parties your material passes through, the easier it is to explain later what did and didn’t happen to it.
If you want a recording tool that has a better chance of convincing others when a dispute breaks out, Atomic Presence is worth getting familiar with before you need it.
