Private by design

Only a hash leaves your device. Your idea text is never transmitted or stored externally — not even we can read it.

Hash only · No exposure
Why MindVault is different

Not just a file stamp.
A full inventor workflow.

Most timestamping tools are file notaries — upload a document, get a certificate. That's it. MindVault is built for the moment before the file exists: when the idea first forms.

Other timestamping tools
  • File prep required before you can timestamp anything
  • No text capture — must have a document first
  • No patent prior art search
  • No idea context or history
MindVault
  • Capture raw ideas as text instantly — no file needed
  • Timestamp the idea the moment it forms
  • USPTO patent search built in
  • Full idea history, searchable and private

Trusted by inventors and independent creators

★★★★★

"I had an idea at 2am and typed it straight into MindVault. Six months later I had a timestamped record that proved I thought of it first. That record saved a negotiation."

Jordan M. — Independent Inventor
★★★★★

"The prior art check alone is worth it. I ran three ideas through it and crossed off two that were already patented. Saved me months of wasted work."

Priya S. — Early-stage Founder
★★★★★

"I used to email ideas to myself as a timestamp. MindVault does the same thing except the proof is cryptographically anchored to Bitcoin. No comparison."
