Questions & Answers

As answered by people managing Zencaptcha 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 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.
