What it does
Instantly supercharge your LLM apps with xmem: a hybrid memory, that combines long-term knowledge and real-time context for smarter, more relevant AI.
Hybrid memory for LLMs: long-term, session, and context management.
Instantly supercharge your LLM apps with xmem: a hybrid memory, that combines long-term knowledge and real-time context for smarter, more relevant AI. Stop losing context and knowledge between sessions. xmem orchestrates both persistent and session memory for every LLM call so your AI is always relevant, accurate, and up-to-date. Store and retrieve knowledge, notes, and documents with vector search. Track recent chats, instructions, and context for recency and personalization. Automatically assemble the best context for every LLM callno manual tuning needed. xMem's knowledge graph links concepts, facts, and user context in real time. This enables your LLMs to reason, recall, and connect…from xmem.xyz

Yet another memory system for LLMs2025 · github.com · ▲165Built this for my LLM workflows - needed searchable, persistent memory that wouldn't blow up storage costs. I also wanted to use it locally for my research. It's a content-addressed storage system with block-level deduplication (saves 30-40% on typical codebases). I have integrated the CLI tool into most of my workflows in Zed, Claude Code, and Cursor, and I provide the prompt I'm currently using in the repo. The project is in C++ and the build system is rough around the edges but is tested on macOS and Ubuntu 24.04.

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!
