ChainMemory gives your AI agents persistent memory that belongs to YOU โ€” not to a single vendor.

Save a memory in ChatGPT, recall it in Claude or Gemini. Available via Chrome extension, MCP server (npm), or REST API. Every memory gets a cryptographic fingerprint and project states are anchored with Merkle proofs, so anyone can independently verify integrity โ€” no trust required.

Memories consolidate into a structured Project Brain (decisions, milestones, risks) instead of a pile of raw notes. Multi-agent native: Claude, Cursor and GPT share one consolidated state. Free tier available.

LLMnesia is a Chrome extension that helps you search, rediscover and reuse your AI conversation history across tools like ChatGPT, Claude, Gemini and other major LLM platforms.

As AI becomes part of everyday work, more and more valuable knowledge gets buried inside old chats: useful answers, research notes, code snippets, product ideas, strategy decisions, prompt experiments, writing drafts and technical explanations. The problem is that most AI platforms are built around starting new conversations, not helping you find the important things you already created.

LLMnesia solves that by turning your AI history into a searchable personal knowledge base. Instead of repeating prompts, scrolling through endless sidebars or trying to remember which platform had the answer, you can quickly search across your past conversations and get back to the information you need.

It is built for people who use AI seriously: founders, developers, researchers, writers, consultants, students, operators and anyone who relies on LLMs for work, learning or creative thinking. Whether you are tracking decisions across projects, finding an old coding solution, revisiting research, or recovering a half-forgotten idea, LLMnesia helps make your AI memory useful again.

The product is lightweight, browser-based and designed around practical everyday retrieval. It focuses on a simple but increasingly important problem: your AI conversations are becoming one of your most valuable knowledge stores, and you should be able to search them properly.

LLMnesia features and specs

  • Novel Concept
    LLMnesia addresses the interesting challenge of memory and context persistence for large language models, which is a known limitation of many LLM-based applications.
  • Focused Solution
    Rather than trying to be an all-in-one AI platform, LLMnesia appears to focus specifically on the memory/persistence problem, allowing it to potentially deliver a more refined solution in that niche.
  • Relevant to Growing Market
    As LLM adoption grows across industries, tools that enhance LLM capabilities like persistent memory are increasingly in demand, making LLMnesia well-positioned in a growing ecosystem.
  • Potential for Integration
    Memory management tools for LLMs can often be integrated into existing workflows and applications, making it a useful addition to developers' toolkits without requiring major architectural changes.
  • Addresses a Real Pain Point
    Context window limitations and lack of long-term memory are genuine frustrations for developers and users of LLM applications, so a tool addressing this fills a real need.

Questions & Answers

As answered by people managing ChainMemory and LLMnesia.

Why should a person choose your product over its competitors?

LLMnesia's answer:

Most AI tools focus on creating new conversations. LLMnesia focuses on recovering the value already locked inside your existing conversations. It is lightweight, browser-based, privacy-conscious, and designed for people who use multiple AI platforms rather than just one. The goal is simple: stop repeating prompts, stop losing good answers, and make your AI history genuinely useful.

What's the story behind your product?

LLMnesia's answer:

LLMnesia started from a real frustration: after using AI tools intensively, the useful answers, ideas, code snippets and decisions were scattered across different platforms and hard to find again. The product was built to solve that problem directly by making AI conversation history searchable, reusable and easier to manage. It grew from a personal need into a tool for anyone who depends on LLMs every day.

What makes your product unique?

LLMnesia's answer:

LLMnesia turns scattered AI chat history into a searchable personal knowledge base. Instead of losing useful answers across ChatGPT, Claude, Gemini and other LLM tools, it indexes your past conversations locally in a Chrome extension so you can search, revisit and reuse what you have already learned or created.

How would you describe the primary audience of your product?

LLMnesia's answer:

LLMnesia is for heavy AI users who rely on LLMs for work, research, writing, coding, product building, learning or decision-making. The main audience includes founders, developers, researchers, writers, consultants, students and anyone who has valuable information buried across many AI chats.

Which are the primary technologies used for building your product?

LLMnesia's answer:

LLMnesia is built as a Chrome extension using modern web technologies, including JavaScript, browser extension APIs, local indexing and search, and integrations with major LLM web platforms. The wider product ecosystem also uses Next.js, TypeScript and Supabase for supporting web and analytics tooling.

Who are some of the biggest customers of your product?

LLMnesia's answer:

LLMnesia is still an early-stage product, so there are no major public enterprise customers to list yet. Current users are individual AI power users, builders, developers, researchers and founders.
