The zero-knowledge architecture with AES-256 is reassuring for sharing sensitive data. I'm curious about the new Burn Box feature—does it support rate limiting or CAPTCHA to prevent abuse when the link is public? For teams sharing credentials or API keys temporarily, that could be a helpful safeguard.

@yamamoto7 yes captcha and date limiting coming out today.

The new 'Burn Box' feature is a game changer! It’s one thing to send a secure note, but having a public link where others can safely send me info without needing an account is super useful. Is there a limit to how many Burn Boxes one can create?

@layli yeah right now each user gets one burn box. I could change that easily but can you tell me why anyone would need more than one?

Congrats on the launch!

Curious how you thought about the UX trade-offs around self-destructing notes vs longer-lived context. Balancing privacy and usability is never trivial.

@dmitry_petrakov this app is about ephemeral self destructing notes. If you’re looking for something that houses longer lived content then burner note isn’t for you. I don’t see it as a trade off at all. It’s more like a completely different use case.

@mickc79 Got it – that framing makes sense.

Thanks for the clarification, and congrats on the relaunch.

Love the zero-knowledge approach with AES-256 encryption! This is exactly what privacy-conscious users need. I'm curious about the architecture - is any AI/LLM involved in the encryption process, or is it purely cryptographic? Also wondering if you plan to add AI-powered features in the future, like smart note categorization using on-device models to maintain zero-knowledge? 🔐

@new_user___01920256530b9f092c9e057 Proudly an AI free zone. I thoroughly believe that everyone ramming AI into their products is a massive symptom of solutions looking for problems. I’m an advocate for AI but only where it makes sense. The trend right now to try and wedge AI into every product is, to me, ridiculous.

Clean execution on a sensitive problem. The combination of open source transparency, zero ads, and one time read deletion builds immediate trust. The cryptographic choices also signal a serious security mindset. From a technical standpoint, how do you handle key generation and storage to ensure true end to end secrecy, and what safeguards exist against replay or partial read attacks?

@urvashi_misal thanks for the message. It’s a very technical question, too much to get into in a comment but I explain all of this on the about page

Great implementation and love the idea! But what if someone wants to take a screenshot.I am able to do that.
