The math most Hunchly users miss
$4.99 = 10 court-ready exhibits = $0.499 per exhibit
Keep your Hunchly subscription for investigation. Add one $4.99 SnapPack per year and never again hand an attorney an MHTML file. Losing a single case because opposing counsel picked apart your local hash costs more than a decade of ProofSnap.
Read this first
Keep Hunchly for the investigation phase.
Continuous browsing log, search, tags, Maltego graph analysis — that workflow is Hunchly’s strength. We’re not asking you to cancel it.
If any case you touch could end in court — add ProofSnap.
- ✓One-click seal of the specific page you will hand an attorney.
- ✓Bitcoin blockchain timestamp — public, non-repudiable, no vendor needed to verify.
- ✓eIDAS qualified timestamp for EU courts (27-state legal presumption).
- ✓Provenance Certificate — answers deepfake challenges before they start.
- ✓$4.99 for 10 exhibits. Used once a year, it pays for itself.
Hunchly and ProofSnap solve different jobs on the same investigator's desk. Hunchly (acquired by Maltego in May 2025, $129.99/year single user) silently captures every page you browse as MHTML with SHA-256 hashes and timestamps — a brilliant forensic OSINT investigation audit trail. ProofSnap is a self-serve Chrome/Edge extension that captures one page on demand and seals it into a self-verifying ZIP with Bitcoin blockchain timestamp, RSA-4096 digital signature, Provenance Certificate with 8 anti-deepfake checks, video of the capture process and an ISO/IEC 27037 chain of custody.
ProofSnap ships from $4.99 one-time (SnapPack, 10 captures), $8.99–$28.99/mo or $18.99/license/mo Company. The Bitcoin blockchain timestamp ships on SnapPack, Professional and Enterprise; Essential ($8.99/mo) is the non-blockchain tier. Enterprise ($28.99/mo) adds an eIDAS qualified timestamp from an EU Qualified Trust Service Provider — satisfying FRE 902(13) and 902(14) self-authentication by qualified-person certification.
Pick Hunchly
for the investigation phase — log everything, search later, document every rabbit hole.
Pick ProofSnap
for the exhibit phase — seal the specific page as a vendor-neutral, blockchain-stamped, eIDAS-ready ZIP you hand to an attorney.

The attack surface
Three ways opposing counsel can challenge Hunchly-only evidence
None of these attacks destroy Hunchly as an investigation tool — but they are why forensic experts pair it with a blockchain-anchored sealer for exhibits. Same arguments, whether you lose the motion or not.
Local-only seal
“The investigator could have modified the MHTML, then re-hashed and re-signed with their own GPG key — the file would still look legitimate.”
Hunchly hashes (SHA-256) and signs (GPG, using a key pair generated on the investigator’s own machine) every MHTML capture. That proves integrity and authorship after the seal — but the private key never leaves the investigator’s laptop, so anyone who has it can re-seal modified content. A skilled expert on cross-examination can pick this apart in two questions.
ProofSnap counter
The manifest hash is anchored to the Bitcoin blockchain via OpenTimestamps — an independent, public record that cannot be backdated or re-signed after the fact.
No timestamp authority
“The date stamp came from your own computer. What stops you from changing the system clock?”
Hunchly’s timestamp is locally generated — reliant on the investigator’s NTP sync, machine time, and good faith. In an EU court no independent authority has attested to when the capture was made.
ProofSnap counter
Enterprise plan issues an eIDAS qualified timestamp from an EU Qualified Trust Service Provider (Article 41 legal presumption in all 27 member states).
Vendor & format familiarity
“The judge has never opened an MHTML file. The expert must come testify about the software before we can even look at the content.”
Every exhibit becomes a mini-tutorial. Attorney cost climbs. Opposing counsel delays. If the expert witness is unavailable or if Maltego changes Hunchly’s output format, your old captures get harder to defend.
ProofSnap counter
Self-verifying ZIP — PDF screenshot, ISO/IEC 27037 forensic log, vendor-neutral .ots and .tsr files any expert re-checks with standard tools. Judge opens the evidence.pdf.
One opposing-counsel win on authentication can torpedo a case. $4.99 buys 10 exhibits that close all three attack surfaces. If a case never goes to court, SnapPack credits never expire.
Get a SnapPack — $4.99 one-timeThe exhibit your attorney actually needs
You get an email from the attorney at 4 p.m.: “I need Exhibit A tomorrow morning — the Twitter post from last Tuesday.” Here is how each tool handles it.
Hunchly path
- 1Open Hunchly Dashboard at
localhost:8080, search case history for the tweet URL. - 2Export the MHTML file and copy the SHA-256 hash manually.
- 3Send MHTML + hash to the attorney. Attorney asks: “What is MHTML and how do I open it in court?”
- 4Attorney drafts an affidavit explaining Hunchly, MHTML and the hashing workflow; you may be called as a fact witness.
- 5Opposing counsel: “The hash only proves integrity after it was computed — nothing proves the MHTML was not modified before.”
ProofSnap path
- 1Open the Twitter post in Chrome or Edge exactly as the public saw it.
- 2Click Capture in the ProofSnap side panel. 30 seconds later you have a ZIP.
- 3Send the ZIP to the attorney. Inside: full-page screenshot, HTML, video of the capture, SHA-256, RSA-4096 signature, Bitcoin blockchain
.otsproof, eIDAS.tsr(Enterprise), Provenance Certificate, ISO/IEC 27037 forensic log, chain of custody. - 4Attorney signs an FRE 902(13) / 902(14) certification using the ZIP contents. No MHTML primer required.
- 5Opposing counsel: “The blockchain timestamp is public, the signature is RSA-4096, the Provenance Certificate answers deepfake. Moving on.”

Cheapest court-grade entry
$4.99 — 10 court-ready ZIPs, $0.499 per exhibit
ProofSnap SnapPack ships the full court-grade bundle (screenshot + HTML + SHA-256 + RSA-4096 signature over manifest + Bitcoin blockchain timestamp + Provenance Certificate + ISO/IEC 27037 chain of custody) at $0.499 per exhibit, one-time purchase, no subscription. Hunchly’s locally-signed MHTML (SHA-256 + GPG .sig) at $129.99/yr has a different job — but when the attorney asks for a sealed exhibit with an independent timestamp, this is the floor.
Who added ProofSnap to their Hunchly workflow
Most of these professionals paid for ProofSnap the day after an authentication fight. Buying SnapPack before your first challenge is the cheap option.
OSINT analysts supporting litigation
Hunchly logs the whole investigation. ProofSnap seals the specific page that ends up in the complaint, deposition exhibit or trial binder — so the attorney is not the one explaining MHTML to the judge.
Private investigators
Deliver attorney clients a self-verifying ZIP they can forward to opposing counsel unchanged. No “please install our tool to view this.”
Cross-border / EU investigators
eIDAS qualified timestamps carry legal presumption of accuracy in all 27 EU member states (Article 41). Hunchly's local timestamps do not. Critical for Germany, France, Italy and Spain.
Journalists publishing screenshots
Source protection aside, the capture needs to survive a defamation threat. Bitcoin blockchain timestamp + Provenance Certificate + RSA-4096 signature is a better story than “trust us.”
Brand protection & anti-counterfeit
Counterfeit listings, rogue marketplaces, infringing ads — preserve specific SKUs with a court-ready ZIP for takedowns, DMCA, Amazon Brand Registry, and marketplace escalations.
HR & workplace investigations
Anti-deepfake Provenance Certificate gives accused employees nowhere to argue “that screenshot is AI-generated.” Blockchain timestamp closes the “backdated” objection.
What does a ProofSnap capture actually contain?
One ZIP. Self-verifying. Hand it to any digital-forensics expert — they can re-check the hashes, signature and timestamps without trusting ProofSnap. This is what Hunchly's MHTML does not provide.

“But Hunchly is the OSINT standard…”
“Bellingcat uses Hunchly.”
Correct — for investigations. Bellingcat's workflow is mostly documentation of open-source research, not courtroom exhibits. Where Bellingcat's findings do hit court (Mueller investigation, MH17, war crimes tribunals), prosecutors typically re-package evidence through a forensic chain of custody that looks very much like what ProofSnap produces out of the box.
“My team is already on Maltego.”
Keep Maltego and Hunchly for graph analysis and case management. ProofSnap sits outside the workflow at the one point where you need a sealed, vendor-neutral exhibit — it does not compete with Maltego's transform ecosystem.
“Hunchly's SHA-256 is enough.”
A local SHA-256 proves integrity after the hash was computed. It does not prove the page was not altered before being captured — and a locally-generated timestamp has no independent authority. Bitcoin blockchain and eIDAS qualified timestamps solve both problems with no vendor dependency.
Also looking at PageFreezer, Page Vault or WebPreserver?
Short read of the other court-capture tools so you don’t waste time running five separate trials.
PageFreezer
Enterprise compliance archiving
Continuous 24/7 archiving of entire websites and social-media accounts for SEC 17a-4, FINRA, FOIA, MiFID II. Quote-based pricing (public listings from ~$99/mo) with annual contracts and $500–$10,000+ implementation fees. Different job from Hunchly and ProofSnap — built for the compliance team, not the investigator. See our PageFreezer vs ProofSnap comparison.
Page Vault
Litigation-focused ($149+/capture, $195+/mo plans)
On-demand captures from $149 per webpage or $299 per social-media collection; software subscriptions from $195/mo for a single concurrent user. Markets itself on FRE 901(b)(9) and provides affidavits from expert witnesses. Typically the most expensive per-capture option for solo attorneys. ProofSnap covers the same FRE 901 / 902(13) / 902(14) ground from $4.99 with published pricing.
WebPreserver Heads-up
PageFreezer’s own Chrome extension (subsidiary since 2018)
Launched 2015 as a PageFreezer SaaS, wholly-owned subsidiary since June 2018. Same enterprise sales model, quote-based pricing, annual-contract expectation as PageFreezer Archiving. If you are comparing WebPreserver to PageFreezer you are comparing two products from the same company.
Silo for Research (Authentic8)
FedRAMP-authorized secure browsing for investigators
Cloud-based secure browsing with full session logging, managed attribution and audit trail — used by federal, state/local and private investigators, positioned as the only FedRAMP-authorized research platform. Excellent for managed-attribution OSINT browsing. Quote-based pricing via Authentic8; not built for on-demand exhibit production: you still need a separate tool to seal a specific capture as a court-ready package with blockchain and eIDAS. Pairs well with ProofSnap at the exhibit stage.
Kiroku, Wayback Machine & free tools
Free local hash + timestamp / free third-party archive
Free tools offer local SHA-256 hashing and a timestamp — stronger than a raw screenshot. They lack blockchain anchoring, RSA-level digital signatures, eIDAS qualified timestamps and a documented chain of custody. Fine for low-stakes preservation, weak for contested litigation. Wayback Machine captures are useful as supporting context but cannot see logged-in or paywalled content.

Frequently asked questions: Hunchly vs ProofSnap
Nine honest answers about tool fit, court admissibility and pricing.
.sig file, signed with a key pair generated locally during installation), local timestamps, metadata, automatic browsing log, search across case history, and tagging/notes — features ProofSnap does not currently replicate because they belong to the investigation workflow, not the exhibit workflow.
chain_of_custody.json with every capture, alongside a forensic_log.json compliant with ISO/IEC 27037 recording device fingerprint, NTP time verification, capture-process video hashes, and every event between capture and ZIP export. Hunchly stores a per-case directory history but does not package an ISO/IEC 27037 forensic log or vendor-neutral chain-of-custody artifact with each export.
forensic_log.json with tamper-evident hash chain, device integrity checks, NTP time verification and full operator attribution, plus a chain_of_custody.json binding the evidence to the operator and the operation. The design aligns with ISO/IEC 27037 recommendations for Digital Evidence First Responders (DEFRs) and Digital Evidence Specialists (DESs) — which is increasingly important as more courts cite the standard when evaluating digital-evidence handling.
Your next exhibit can’t fail authentication.
The case you lose to an authentication challenge costs more than a decade of ProofSnap. $4.99 buys 10 blockchain-stamped exhibits — hand your attorney a ZIP any expert can re-verify without Hunchly, MHTML or a vendor affidavit.
Trial: credit card required, cancel before day 7 — no charge. SnapPack: one-time $4.99, no recurring bill, credits never expire.
