Gemini

Gemini is Google's flagship AI assistant, built into the products a billion people already use — Search, Gmail, Docs, Sheets, Android and Chrome. Ask it to draft an email in Gmail, summarize a Google Doc, analyze a spreadsheet, or answer questions with live information from Google Search, and it works where you already are.

The free tier is generous and includes multimodal chat (text, images, voice), file analysis and image generation. Google AI Pro at $19.99/month adds the most capable models, deep research features, higher limits, and extras like expanded Google Drive storage; a premium Ultra tier ($249.99/month) targets professionals who want the absolute latest.

Strengths: the deepest integration with everyday tools of any AI assistant, live web-grounded answers, strong multimodal abilities (it handles video and audio understanding well), and one of the best free tiers on the market. Weaknesses: writing style can feel flatter than Claude's, and quality across its many integrations varies.

Who it's for: anyone living in Google's ecosystem. If your work happens in Gmail, Docs and Drive, Gemini removes the copy-paste dance other assistants require. Students get a lot for free, and Android users get a genuinely useful phone assistant. Writers who prioritize prose quality may still prefer Claude, and users wanting maximum plugins may prefer ChatGPT.
