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.

Answer is built with Golang and Typescript.
Tempreon's answer:
The protocol choice is the product decision: build on the open standard, and your memory works everywhere the standard does.
Apache Answer's answer
Answer is a knowledge-based Q&A platform software suitable for teams of any size. It was open-sourced by the SegmentFault team on the first day it launches. In October 2023, it passed the vote and was accepted to the Apache Software Foundation (ASF) Incubator.
We aim to help every team create their Q&A community, gather collective intelligence, and drive industry progress. You can use Answer for free to create your Q&A platform, whether it's for a community forum, a help center, or a knowledge management platform. You always own your community, and it's for FREE.
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.
Apache Answer's answer
It's FREE. It's easy to start, it's safe, and you always own your community.
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.
Apache Answer's answer
It's open source, and it embraces an open editing and collaboration spirit. It's an online home for you and your community members. Through asking and answering, you'll build a powerful knowledge net, and a thriving community where everyone matters.
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.
Apache Answer's answer
Apache Answer is built for teams at any scales. No matter it's for team discussion, knowledge base, or support center, online forum, we always keep you in a good company.
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.
