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.
Block Protocol 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.

Off the top of my headโฆ Tools for transclusion, inserting parts of other docs and rich references to them: https://en.wikipedia.org/wiki/Transclusion i.e. I refer to lobste.rs and Hacker news stories in posts like this: https://www.oilshell.org/blog/2021/04/build-ci-comments.html I wrote a bit of (offline) JavaScript to do it, but I could see it being expanded. I find it makes the posts more like a conversation... - Source: Hacker News / over 2 years ago
Looks like that's using lit-html templates inside Svelte, but not any custom elements. Web components would be good because they're an interface that Primo could work with without relying on specific implementation details. They're also encapsulated with shadow DOM, and support interoperable composition (components can have child elements made from any other frameworks or library). So you could still build blocks... - Source: Hacker News / about 3 years ago
Any chance this might interact with Block Protocol in any way? https://blockprotocol.org/ The obvious immediate benefit to this would be native editing of Wordpress blocks for your website. But if this became standardized and usable both locally and on the web, it could open up all sorts of interesting use cases. - Source: Hacker News / about 3 years ago
I think the โserversโ should be abstracted away from the user. Communities should be able to exist seamlessly across multiple servers, and the user shouldnโt need to know what servers a community is on. They should just be able to go to one website and access the entirety of the fediverse. Activities should adopt something similar to the Block protocol (https://blockprotocol.org/) so they can specify how they... Source: about 3 years ago
The universal block thing...that's actually not too far from what is happening. WP didn't invent blocks, they adopted the Blocks Protocol. It's slow moving, with only a couple CMS's supporting it at the moment, but Drupal, Github, and Figma are planned to implement it as well. The idea being to enable a web standard for blocks that makes then platform agnostic. Use them anywhere on the web you like. Source: about 3 years ago
