What it does
OTI (One Time Information) is a modern web application designed for secure, one-time information sharing. It ensures safe sharing of sensitive information using client-side encryption.
A private note should not become permanent history. Encrypt it here, send one link, and let the message disappear after it is read. Encryption starts in this browser. OTI receives ciphertext, never the readable note. The raw file never reaches the server. Only its encrypted envelope is stored. The complete link includes the private key in its fragment. OTI never receives that part. Scan the code to open the one-time link on a different device. It tells you when the message was opened without revealing what it contained. Your browser does the encryption before OTI receives anything. We only hold an unreadable payload until its timer runsfrom oti.karacabay.com

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
