Capture web pages and documents before they change or disappear. Paid captures are fingerprinted and stored on Arweave's permanent decentralized network. Eligible article saves stay temporary for up to 7 days. Pay before expiry to make them permanent; unpaid saves are deleted. Pay once. No subscriptions.

A complete pipeline from URL to permanent storage.
Paste any URL or upload a document. Permavault captures the page as it exists right now: content, screenshot, PDF rendering, and a technical record of how it was retrieved.
Your capture lives on Arweave, a network of hundreds of independent nodes worldwide, funded by a long-term storage endowment. Designed for permanence, not monthly invoices.
See exact file size and Arweave storage cost before you commit. No hidden fees.
Source adapters are modular npm packages. Add new content types or build your own.
Power users get a full CLI. Curators get a clean web dashboard. Same engine underneath.
Archive thousands of URLs via CSV. If something fails, retry without re-downloading.
Drop a link to any public web page, or upload a document. Permavault detects what it is and prepares the capture.
Review the page details and the displayed one-time USD price or size limit before starting. A metadata preview does not show the finished capture.
After a paid capture is stored, you receive its transaction link and sealed record. Availability and timestamp confirmation may follow later. Free article saves become permanent only after payment.
Capture time varies by page and file. Check storage and proof status in the app.
Choose the capture path that fits the material you need to preserve.

This is a real evidence package from a real capture of this very page. Download it and check every proof yourself with standard tools. No signup, no Permavault account, no trust required.
Hand it to opposing counsel, an expert, or a judge. A plain-English guide inside every package walks them through it, and the hashes and signature check fully offline with free tools: your evidence keeps verifying even if Permavault disappears.
unzip permavault-sample-evidence.zip && bash verify.shChecks the file hashes, the Ed25519 signature, and the permanent Arweave copy with shasum, OpenSSL 3 or later, and curl. On a Mac, add a current OpenSSL first with brew install openssl.
The permanent captures below are fingerprinted, sealed, and stored on Arweave. Eligible article saves cost $0.99 to make permanent before their 7-day temporary storage expires. Pay in USD by card.

Often yes, when nobody contests them. The trouble starts when someone does. What courts have actually done with screenshot evidence, why it fails, and what to capture instead.
