Hey Product Hunt! 👋 I’m Benoit, CEO of Tokkun Studio in Kyoto. As a business owner, I was tired of e-signature tools that were either: Too expensive (looking at you, DocuSign $45/mo plans). Too complex (I just want to timestamp a document, not configure a workflow for 20 minutes). Not secure enough (a simple PDF scribble isn't real proof). So we built ClientsOK. It’s designed to be the fastest (and mobile friendly) way to create court-ready proof. Whether you are a freelancer protecting your IP, a landlord signing a lease, or a judicial expert needing timestamped evidence. Why it's different: 🛡️ 14-Point Forensic Evidence: We don't just record a signature. We capture everything: IP geolocation, browser fingerprint, precise timestamp, and device info. ⛓️ Bitcoin Anchoring: We use SHA-256 hashing to anchor proofs on the Bitcoin blockchain. This means your proof is verifiable independently of us, forever. 🇪🇺 Global Compliance: Fully compliant with eIDAS (EU) and E-SIGN (US). For the PH Community: You can start with our Free Plan (1 document/month, max 2MB) to test the speed. And for developers, we have a public API to automate certification for just $0.50/doc. I’d love to hear your feedback! Are you Team "Complex Workflows" or Team "Speed"? Cheers from Japan, Benoit
