- 1Datastory launches AI data storytelling with open knowledge graph●Show HN: Datastory, Data storytelling with AI and an open knowledge graph
A new tool called Datastory has been launched, combining AI-generated data storytelling with an open knowledge graph. The launch was shared with the Hacker News community, where it drew early attention and modest engagement. The project is aimed at helping users turn raw data into narratives backed by an openly accessible graph of linked knowledge.

A developer recounts six weeks troubleshooting AI agents that contradicted each other, repeated work, and confidently cited unverified facts. Upgrading models, rewriting prompts and adding a knowledge graph failed to fix the issues, pointing instead to how the agents share and manage context across tasks. The write-up is drawing attention from practitioners facing similar multi-agent reliability problems, as teams increasingly deploy agent systems in production and discover coordination, not raw model intelligence, is often the bottleneck.

A developer project called CodeGraph by colbymchenry is gaining attention on GitHub. It builds a pre-indexed knowledge graph of a codebase that automatically syncs as code changes, and works with popular AI coding assistants including Claude Code, Codex, Gemini, Cursor, Copilot and others. The tool runs fully locally and aims to cut token usage and reduce the number of tool calls needed when AI agents navigate large projects.
