ModelWatch

ModelWatch is a standalone local Python 3 CLI tool that monitors official AI vendor pages for pricing, release, deprecation and policy changes. It confirms persistent changes across two consecutive checks, produces unified diffs, classifies impact, extracts future actionable dates and can generate local .ics calendar reminders. OpenAI, Google Gemini, xAI and Anthropic sources are included by default. No API keys or third-party Python packages are required.
