Tempreon is a personal memory layer for your AI tools, connected over MCP. Your knowledge, preferences, and decisions travel across Claude, ChatGPT, Cursor, and any MCP-capable client โ€” captured once, available everywhere. It learns how you actually work instead of just storing what you said.

Tempreon features and specs

  • Cross-LLM memory
    Knowledge captured in one assistant is available in all of them โ€” Claude, ChatGPT, Cursor, any MCP-capable client.
  • Core Imprint
    A structured identity layer โ€” who you are, how you work, what you care about โ€” 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 โ€” 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 โ€” including via memhaul, our free open-source export CLI.
  • You own your data
    Export everything, anytime. We monetize the service, never the custody.

JSFiddle features and specs

  • Easy Sharing and Collaboration
    JSFiddle allows users to share and collaborate on code snippets effortlessly by generating unique URLs for each project.
  • Real-Time Editing
    Changes made to HTML, CSS, and JavaScript are displayed in real-time, providing instant feedback and streamlining the development process.
  • Supports Multiple Frameworks
    JSFiddle supports various JavaScript frameworks and libraries such as jQuery, Vue.js, and React, allowing developers to experiment with different technologies.

    Users can embed their fiddles directly into websites or blogs, enabling easy demonstration of code and concepts.
  • Version Control
    JSFiddle offers version control, allowing users to save different versions of their code and revert to previous versions if needed.

Possible disadvantages of JSFiddle

  • Limited Backend Support
    JSFiddle is primarily focused on frontend development and does not provide robust backend development capabilities.
  • Performance Issues
    With complex or resource-intensive projects, JSFiddle can experience performance lag, impacting the user experience.
  • Basic IDE Features
    Compared to full-fledged Integrated Development Environments (IDEs), JSFiddle lacks advanced features such as code linting, debugging tools, and extensive plugins.
  • File Management
    JSFiddle does not offer comprehensive file management, making it challenging to work on larger projects with multiple files.
  • Dependency Management
    Managing dependencies can be cumbersome, as JSFiddle does not provide built-in tools to handle package management seamlessly.

Questions & Answers

As answered by people managing Tempreon and JSFiddle.

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 โ€” your context, your preferences, your judgment โ€” 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 โ€” 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 โ€” 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 โ€” 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 โ€” Claude, ChatGPT, Cursor, anything MCP-capable.

  • It learns, it doesn't just store. How you work, what you decide, how you like things done โ€” 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 โ€” you're the audience.

Which are the primary technologies used for building your product?

Tempreon's answer

  • Model Context Protocol (MCP) over streamable HTTP โ€” 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.
