AICF – a tiny "what changed" feed for AI/RAG (v0.1 minimal core) [Developer Tools]
5 points, 1 comments
A minimal, web-native changefeed for AI/RAG systems to track and update only modified content sections.
- Uses a simple JSON discovery mechanism (
/.well-known/ai-changefeed) to locate the feed. - Append-only NDJSON format with four required fields (id, action, url, time) and optional hints (anchor, checksum, note).
- Reduces unnecessary crawling and re-embedding by focusing on changed content.
- Designed for keeping docs, pricing, and policy pages fresh for AI/agents.
- Open-source spec with examples available on GitHub.

BrowserOS -- browser agents with GPT-OSS, local llms [Developer Tools]
11 points, 2 comments
BrowserOS is an open-source agentic web browser fork of Chromium that enables non-developers to create and run local browser agents with GPT-OSS and local LLMs.
- Fork of Chromium designed for building and running browser-based agents
- Supports three agent creation methods: drag-and-drop workflows, one-shot agents, and plan-follower agents
- Optimized for plan-follower agents, where users provide step-by-step instructions for higher reliability
- First-class support for local LLMs (e.g., via Ollama or LMStudio) with a focus on privacy
- Demo shows an 80% success rate with structured plans compared to 30% with one-shot agents
