What it does.

Monitors configurable official AI-vendor pages locally, with OpenAI, Google Gemini, xAI and Anthropic included by default.

Creates a local baseline on first run and compares later checks against it.

Requires the same changed content to persist across two consecutive checks before accepting it as a confirmed change.

Produces a unified diff and classifies confirmed changes as INFO, COST, DEPRECATION, BREAKING, CAPABILITY or POLICY.

Extracts future actionable dates from confirmed changes and can generate local .ics calendar reminders linked to the official source.

Supports JSON output for agents and automations.

Requires no API keys and no third-party Python packages.

Treats fetched web content as untrusted data and never executes it.

What’s inside.

Everything you need in the bundle. No tutorials. No assembly.
