Prove what you submitted, and exactly when.
Submit a patent draft, trademark, design, idea, theory, prediction or research paper. Mindgate fingerprints it at upload, compares it with patent, paper, trademark, book and code repositories using three independent AI models, and anchors the record on a blockchain.
Change one letter and every hash changes. Nothing you type here leaves your device.
From upload to certificate
Eleven steps and one decision. The submission time is fixed at step 2 and never moves.
Submit
Text, PDF or DOCX, up to 200,000 characters and 10 files.
Hash and timestamp
SHA-256 of your content and the UTC time are fixed at upload.
Pay
USD 1,000 via Stripe Checkout, charged up front.
Intake and compliance
Classification, moderation and duplicate screening; public-safe queries.
Parallel search
Official APIs only, with abstracted keyword queries – never your text.
Similarity engine
Ranks the closest 20 records with text, claim and mark signals.
LLM 1 – analyst
Scores each match and explains the overlapping elements.
Citation check
Every citation must exist in the retrieved pool and resolve.
LLM 2 – validator
A different vendor re-scores and looks for missed matches.
LLM 3 – adjudicator
Resolves conflicts. A gap above 20 points means provisional plus human review.
Certificate and anchor
Signed PDF, proof bundle, Merkle anchor and public registry entry.
What the certificate says – and what it never says
Every word on a Mindgate record is chosen so that it stays true.
Mindgate does
- Hash, timestamp and anchor your submission
- Compare it against listed public repositories
- Score similarity and cite verified matches
- Issue a certificate whatever the score
- Publish searchable metadata only
Mindgate does not
- Grant, register or validate any IP right
- Verify who owns or invented the work
- Opine on patentability, validity or infringement
- Guarantee the search is complete
- Publish your content without your opt-in
Three vendors, three independent opinions
Using models from different companies reduces correlated errors. Versions are pinned and printed in every report.

All vendors operate under zero-retention, no-training API terms. Your submission is passed to them as data, never as instructions.
One fixed fee per submission
The fee buys the comparison and preservation – not a favourable result. A certificate is issued even at a score of 0. Publication in the portal is included.
This page is a public cryptographic record establishing prior art and a verifiable timeline of authorship. It is not a patent, patent-pending application, or statutory IP grant.
