HashShot anchors every screenshot to public blockchains the moment it's captured — giving courts, law firms, and enforcement agencies mathematical proof that an image hasn't been altered.

The HashShot ecosystem

Two tools that turn a screenshot
into court-admissible proof.

A capture surface for everyday use, and a verification app that any third party can run to confirm an image hasn't been touched.

Capture & hash, in one click.

Every screenshot is hashed locally with SHA-256 and anchored to a public ledger before it ever leaves your machine. Tamper-evident from the moment of capture.

Bulk verification, at evidence scale.

Point HashShot at a folder of any size and it re-derives every hash, checks it against the on-chain record, and flags anything that's been altered. Built for law firms, courts, and enforcement agencies.

How it works

Four steps. No proprietary trust.

HashShot leans on math and public infrastructure, not on the company. Anyone — opposing counsel included — can independently verify the proof.

01 · Capture
A screenshot is taken.
From the extension or any HashShot-aware tool. Pixels are committed locally before any network call.
02 · Hash
SHA-256 is computed in the browser.
The raw image bytes are reduced to a 64-character fingerprint. The image itself never has to leave your device.
03 · Anchor
The hash is written to a public ledger.
Once a block confirms, the timestamp and the fingerprint are mathematically frozen — nobody can change either, ever.
04 · Verify
Anyone can re-derive the hash.
Drop the file into the verification app, or check the block on any explorer. The hashes match, or they don't.
Built for evidence workflows

Drop in a folder. Walk out with a defensible record.

The HashShot Verification App is a desktop tool that watches a folder, re-derives every screenshot's hash, and produces a CSV-ready evidence log — without uploading a single image.

Where HashShot is used

Proof for a world where images can be re-written in seconds.

Generative tools have collapsed the cost of fabrication. Cryptographic anchoring restores a single, unforgeable source of truth — the hash, fixed in public, at the moment of capture.

IP infringement & counterfeit takedowns
Time-stamp infringing listings, posts, and stores the moment you find them — before the defendant gets a chance to scrub the page.
< 60s
Capture to anchor
Regulatory disclosure & compliance
Prove what a public-facing dashboard, T&Cs, or pricing page said on a given day — even if it has since been quietly edited.
SHA-256
Cryptographic chain
Internal investigations
Preserve workplace-conduct evidence, harassment screenshots, and chat-app messages with a chain of custody that doesn't rely on the investigator's word.

Law enforcement & OSINT
Open-source intelligence is only as good as its provenance. HashShot fixes the source — and the time of capture — beyond dispute.
Public ledger
Independently auditable

Capture evidence.
Prove integrity.

Install the extension in under a minute. Every screenshot you take from then on is a defensible record — by default.
