Privnote features and specs

Self-Destructing Notes
Notes automatically delete themselves after being read, enhancing privacy and security by ensuring that the content cannot be accessed more than once.
No Sign-Up Required
Users don’t need to register or create an account to use the service, allowing for quick and anonymous note creation.
Encryption
Notes are encrypted to secure the content from unauthorized access during transmission, adding a layer of security.
Ease of Use
The interface is straightforward and user-friendly, making it easy to create, send, and read notes even for non-technical users.
URL-Based Sharing
Notes are shared via unique URLs, facilitating easy sharing through emails, instant messaging, or other digital communication channels.

Possible disadvantages of Privnote

Temporary Availability
Once a note is read and self-destructs, it cannot be retrieved, which could lead to loss of important information.
Potential Phishing Risks
The format of sharing via URLs can potentially be exploited for phishing attacks if users are not cautious about the source of the message.
Limited Features
Privnote focuses solely on secure note sharing, lacking additional features like attachment support, rich text formatting, or integration with other services.
Reliance on Third-Party
Users must trust the service provider to properly handle and secure their data, which may be a concern for highly sensitive information.
No Inherent Authentication
There is no user authentication on either side (sender or recipient), which could lead to unauthorized users accessing the note if they intercept the URL.

Tempreon features and specs

Cross-LLM memory
Knowledge captured in one assistant is available in all of them — Claude, ChatGPT, Cursor, any MCP-capable client.
Core Imprint
A structured identity layer — who you are, how you work, what you care about — seeded in about 15 minutes.
Knowledge Vault
Your personal knowledge and files, stored once and retrievable by meaning, not just keywords.
Learning System Layer
Tempreon learns from your decisions and feedback over time — instincts, not just storage.
One-URL connect (Bridges)
Connect any MCP-capable client by pasting a Bridge URL; OAuth 2.1 handles authorization in your browser.
Memory import
Bring your existing ChatGPT or Claude memory with you — including via memhaul, our free open-source export CLI.
You own your data
Export everything, anytime. We monetize the service, never the custody.

Questions & Answers

As answered by people managing Privnote and Tempreon.

What's the story behind your product?

Tempreon's answer:

Tempreon started with a simple observation: AI models keep changing, but the thing that makes them useful to you — your context, your preferences, your judgment — gets rebuilt from scratch inside every tool, and lost every time you move.

We built the layer that fixes that: person-owned memory served over the open Model Context Protocol, so it works across assistants instead of belonging to one. Along the way we open-sourced the pieces that are useful to everyone regardless of whether they use Tempreon — like memhaul, our MIT-licensed CLI for turning ChatGPT and Claude data exports into files you own.

The through-line is custody: the model is temporary, your memory shouldn't be.

Why should a person choose your product over its competitors?

Tempreon's answer:

Most alternatives in this space are memory infrastructure for developers building their own AI apps. If you're the person using several AI tools every day, that's not your problem — your problem is re-explaining yourself to each of them and losing everything when you switch.

Tempreon solves that one: one memory, every assistant, no re-onboarding.
The model landscape changes every few months — a memory layer that belongs to you is the thing that shouldn't.
No lock-in by design: plain-text exports, open-source export tooling, portable formats.

The choice is really about who the memory is for. Ours is for you.

What makes your product unique?

Tempreon's answer:

Tempreon is built for the person, not the app. Most memory products are developer APIs for adding memory to a single product; Tempreon is a memory layer you own that travels with you across every AI tool you use — Claude, ChatGPT, Cursor, anything MCP-capable.

It learns, it doesn't just store. How you work, what you decide, how you like things done — refined over time, not filed away.
One memory, every assistant. Captured once in one tool, available in all of them. No re-explaining yourself.
Custody is structural, not marketing. Your data exports anytime, the formats are portable, and our export tooling (memhaul) is open source. We monetize the service, never the custody.

How would you describe the primary audience of your product?

Tempreon's answer:

Individuals who live in AI tools all day: operators, consultants, founders, sales professionals, and knowledge workers who use more than one assistant and are tired of being a stranger to each of them.

If you've ever pasted the same context into Claude and ChatGPT in the same week — you're the audience.

Which are the primary technologies used for building your product?

Tempreon's answer:

Model Context Protocol (MCP) over streamable HTTP — the core of it. This is what makes Tempreon work in any compliant client rather than one walled garden.
OAuth 2.1 with dynamic client registration and PKCE for authorization.
TypeScript and Postgres under the hood.

The protocol choice is the product decision: build on the open standard, and your memory works everywhere the standard does.

Don’t trust your messenger
Also, there are services like privnote.com. And even better with a virtual keyboard, so that the message does not need to be typed on the keyboard, but typed with the mouse. But this option will not be a panacea either, in theory, on a computer or mobile device, you may already have a program that will take screenshots of all your actions. Source: over 4 years ago
