What it does

A private, encrypted online notepad. Your notes never leave your browser in plaintext. Multiple passwords unlock different notebooks on the same URL, and a zero-knowledgefvault backup lets you migrate or self-host without ever decrypting on the server — a deniable alternative to ProtectedText, Standard Notes, CryptPad, and Privnote, with a fully open-source frontend, Cloud Functions, and Firestore rules.

Pick a URL, set a password, write. One Flowvault link can hold up to 64 independent notebooks behind 64 different passwords — each unlocks its own private workspace, and the server sees one indistinguishable blob either way. Hand over a decoy if you're ever forced to; your real notebook stays invisible. No account. No email. Your password is your only key — we never see it. How does this compare to ProtectedText, Standard Notes, CryptPad, Privnote? Prefer to keep the ciphertext on your own disk? Store the entire vault as a single .flowvault file and nothing ever reaches our servers. We've pre-loaded a vault at /s/demo with two different notebooks behind two different passwords.

    Hi 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…

  • With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
