jelvibe25on Ask HN: What are you working on? (February 2026)

I got tired of uploading my data to ChatGPT, having a useful conversation, then realizing a week later I need to re-upload again, because data changed. Built ctxsync to fix it:

• Connect GitHub repos, documentation sites, files

• Sync on demand or schedule – your AI's knowledge stays current

• Data isolation: each chat runs in separate containers, no cross-contamination

Uses your own LLM API keys (OpenAI, Anthropic, Kimi-Code).

Tech stack: Elixir, Phoenix, Ash, Oban

Currently working on Klugli - Educational app for German primary school kids (Grades 1-4).

Parents set up accounts, kids log in with simple codes and work through curriculum-aligned Math and German exercises. Built with Elixir/Phoenix/Ash and LiveView.

The hard part isn't the tech - it's creating content that actually maps to the German school curriculum rather than generic "educational" fluff. Currently grinding through grade 2 math topics.
