Own your AI's context and memories across every model and device
Hey HN, I pay for ChatGPT, Claude, Cursor, and use Gemini through work. Four vendors, four separate conversation histories, four profiles of how I think. None of them talk to each other. Switch providers and you start over. So I built a system where the memory is mine. I run a knowledge graph in Postgres (Supabase, free tier) with pgvector for semantic search. A small MCP server reads and writes to it. That server sits behind an MCP Gateway on a $6/month VPS, along with Brave Search and a GitHub server. TypingMind connects to the gateway as a BYOK client -- any model, any device, same…

OpenAI is exploring ads in ChatGPT . Anthropic's "Constitutional AI" guardrails are crumbling under pressure from the Pentagon . Google trains on everything you feed Gemini . Nobody knows exactly what these companies will do with the thousands of conversations you have poured into their products -- your debugging sessions, your medical questions, your relationship problems, your business plans -- but the incentives are not subtle. They want you dependent on their product, and your conversation history is the lever. Each of them remembers what you tell their models, and each of them locks that history inside their own app. Switch from Claude to ChatGPT and you start over. Switch to Gemini…from github.com

ChatGPT knows my project details, Cursor forgets them, Claude starts from zero… so I end up re-explaining myself dozens of times a day across these apps. The deeper problem 1. Not portable – context is vendor-locked; nothing travels across tools. 2. Not relational – most memory systems store only the latest fact (“sticky notes”) with no history or provenance. 3. Not yours – your AI memory is sensitive first-party data, yet you have no control over where it lives or how it’s queried. Demo video:…
Bindly2016 · bind.ly · ▲76Hi HN, I’m a product designer by background, not a traditional software engineer. Over the last year, tools like Claude and ChatGPT completely changed how I work. I started with small internal tools, and now I’m “vibe coding” multiple highly personalized apps. As I iterated between Claude Code (implementation) and ChatGPT (ideation / thinking), I kept running into the same problem. To think clearly, I had to repeatedly re-explain: - what the code currently does, - what changed recently, - and why certain decisions were made. That re-summarization step became a real bottleneck. So I…
