Hi PH 👋 I'm Gianluca, an architect from Milan. iTellu started from a simple frustration: I kept saying "I told you so" and couldn't prove it. So I built a way to seal a message today and open it later — with a real certified timestamp. People also use it for letters to open at a graduation or a wedding. It's free and runs in your browser. Honest feedback welcome!
I'm Gianluca, an architect from Milan — not a developer, not a startup guy. I built iTellu nights and weekends because I wanted one simple thing: to say "I told you so" with actual proof.
Here's how it works: you write a message today, it seals itself, and it opens on the date you choose. Every iTellu is encrypted end-to-end in your browser (we can't read it — nobody can) and sealed with an RFC 3161 certified proof, so no one can claim you wrote it after the fact.
People use it to lock in predictions before they happen, or to write letters to the future — to a friend getting married, to a newborn, to themselves.
It's free, works right in the browser, no app to download.
The timing isn't random: the World Cup just kicked off. My own prediction for the winner is already sealed — it opens July 19th, the day of the final. 🔒
I'd genuinely love your feedback, especially on what would make you actually use it. Ask me anything!
