Mem0 Browser Extension: Shared Memory Across ChatGPT,Claude,Perplexity
Hey HN! We're Deshraj and Taranjeet. We've been building working on a startup called Mem0, building an open-source memory layer for AI apps and agents (https://news.ycombinator.com/item?id=41447317). We also kept running into our own daily frustrations with AI assistants forgetting everything between conversations. Over a weekend, we decided to hack together a Chrome extension to solve this for ourselves. The problem was simple: we were constantly re-explaining our context across platforms when switching between ChatGPT, Claude, and Perplexity. Start a coding discussion in…
Mem0 Browser Extension: Shared Memory Across ChatGPT,Claude,Perplexity launched on November 4, 2024 with 34 votes, #596 of 4,990 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
Mem0 Browser Extension is a Chrome tool that preserves conversation context across ChatGPT, Claude, and Perplexity. Built on an open-source memory layer, it eliminates the need to re-explain context when switching between AI platforms. Users can start a discussion on one service and seamlessly continue on another without losing information, making it useful for those who regularly work with multiple AI assistants during research, coding, or creative projects.

Lovable▲1,477Hey HN! Previous CERN physicist turned hacker here. We've developed a way to make AI coding actually work by systematically identifying and fixing places where LLMs typically fail in full-stack development. Today we're launching as Lovable (previously gptengineer.app) since it's such a big change. The problem? AI writing code typically make small mistakes and then get stuck. Those who tried know the frustration. We fixed most of this by mapping out where LLMs fail in full-stack dev and engineering around those pitfalls with prompt chains. Thanks to this, in all comparisons I found with: v0,…

I wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]: > If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos. Hopefully I did that? Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub: https://github.com/kentonv/lanparty Anyway, if this shouldn't have been Show HN, I apologize!
