Tracking what they’re building

Observed site activity — new pages appearing on each platform’s website, updated daily.

What is the LLM Changelog?

The LLM Changelog is a live, automated tracker that monitors release notes and documentation updates across the largest AI platforms — including OpenAI's ChatGPT, Google's Gemini, Perplexity AI, Microsoft Copilot and Google Search. Changes are crawled daily and presented in a single, searchable feed.

Why AI Platform Changes Matter for Brands

When AI models update their training data, adjust ranking signals or change how they cite sources, the brands and products they recommend can shift overnight. An API change to Gemini or a new feature in ChatGPT can alter which businesses get mentioned in millions of AI-generated responses.

Platforms We Track

We currently monitor ChatGPT release notes, OpenAI developer and model changelogs, Gemini API and app updates, Perplexity product and API changes, Microsoft 365 Copilot release notes, and Google Search Central documentation updates. New sources are added as the AI landscape evolves.

Built by reconnAI

reconnAI tracks how AI systems represent brands in their responses. We monitor mentions, sentiment and citations across ChatGPT, Gemini, Perplexity and more — helping businesses understand and improve their visibility in the age of AI search. Learn more →
