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.

TempreonTempreon'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.
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.
The choice is really about who the memory is for. Ours is for you.
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.
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.
Tempreon's answer:
The protocol choice is the product decision: build on the open standard, and your memory works everywhere the standard does.

Bear is what you get when someone builds a notes app that respects developers. It's clean, fast, supports full Markdown, and syncs across devices. Unlike Obsidian, it doesn't require you to set up a vault structure and plugin ecosystem before you can write a single note. - Source: dev.to / 5 months ago
I kept track of bugs and ideas in Bear which, if you're in the Apple ecosystem, I highly recommend. When I stumbled on a good idea for a component that might be fun to build (sup, flip card), I'd write it down. - Source: dev.to / 11 months ago
It's odd that this blogging system is using a name also in use by a writing tool: https://bear.app/. - Source: Hacker News / 11 months ago
I got this confused with the Bear note-taking app for a minute (https://bear.app/), since it's in a closely adjacent domain and even has similar value statements. Unfortunate naming collision. - Source: Hacker News / 11 months ago
Bear app is so damn good at markdown (by default) https://bear.app. - Source: Hacker News / about 1 year ago
