Google's AI that quietly became scary good. The killer feature is the 1 million token context window - you can feed it an entire book, a full codebase, or hours of meeting transcripts and it just handles it. Deep integration with the Google ecosystem means it can pull real-time data from Search, reference YouTube videos, work with your Drive files, and cross-reference Maps data. Gemini 2.5 Pro is their best model - excellent at coding, analysis, and creative tasks. The free tier gives you access to most features with generous limits. Advanced plan at $19.99/month unlocks the full context window and priority access. If you're already in the Google ecosystem, this is a no-brainer.
