Show HN: Ambient Context v1.0.0 (Missing context for AI assistants)

Hacker News - Wed, 09/09/2026 - 7:40pm

The other week I posted a concept to use the macOS Accessibility API to capture the text on your screen into a markdown file. It seemed to be interesting with 150+ github stars.

I've done a bunch of updates and packaged them into a signed macOS app.

One of the biggest changes was moving away from 'one context file per day' to three markdown files for apps, website, and messages.

I then run Andrej Karpathy's LLM Wiki process to turn into a simple knowledge base for the day. This is then used by a smarter model to synthesise into a daily overview.

Let me know what you think

Show HN: EmbedFlow –> Upgrade embedding models without re-embedding your corpus

Hacker News - Wed, 09/09/2026 - 7:34pm

I was playing around with embedding models and I realized the moving between embedding models on a large corpus can cause a huge backfill, as all of the previous documents would have to be re embedded.

embedflow tries to forgo that; it takes candidate documents from the previous index, and reranks them in realtime with the new model. It supports faiss, qdrant, and pgvector

people who have migrated large production vector indexes, would this be helpful for you?
