3-Way Subscription Comparison · All ~$20/mo
All three cost roughly $20/mo. None is universally the best — each wins in its lane. This page tells you which lane you're in.
The safest default pick. Unlimited text chat, GPT-6 Astra, image generation, voice and Codex. Not the best at any single task — but it handles everything.
The highest-quality text output of the three. Claude Opus 5.5 leads coding by Anthropic's SWE-bench Pro figure, Sonnet 5.5 is the strongest writer, and Claude Code is included. Fewer extras — no image generation — and the tightest usage limits.
The only plan that lives inside the tools you already use — Gmail, Docs, Sheets, Drive. A 1M-token window in the Gemini app, Deep Research, and bundled storage. Formerly sold as Google One AI Premium and Gemini Advanced.

Context window | 1.05M-token models GPT-6 family, as listed for the API | 1M-token models Opus 5.5 and Sonnet 5.5; long inputs drain limits fast | 1M tokens in the app Free is capped at 32K |
Long-doc research | Good Handles long inputs, hits limits on huge docs | Very good Stays coherent across large inputs | Best-in-class Deep Research plus Drive and Docs in one place |

ChatGPT Plus is the best all-rounder — unlimited text chat, GPT-6 Astra, image generation, voice and Codex in one plan. Claude Pro wins on writing and coding quality, with Claude Opus 5.5 and Claude Code included. Google AI Pro (formerly Gemini Advanced) wins if you live in Google Workspace.
For most professional writing, yes. Claude Sonnet 5.5 and Opus 5.5 hold tone and structure across long drafts better than the alternatives, and Anthropic built Sonnet 5.5 specifically for polished documents. ChatGPT Plus is close enough that switching for writing alone rarely pays off if you already use it.
If you already use Google Workspace (Gmail, Docs, Sheets, Drive), yes. Google AI Pro puts Gemini inside those tools, raises the Gemini app's context window from 32K to 1M tokens, and bundles Google storage. If you don't use Google Workspace, ChatGPT Plus or Claude Pro offer better standalone value.
Yes — at $60/mo combined. Many power users run Claude Pro for writing and coding, ChatGPT Plus for image generation and voice, and Google AI Pro for Google Workspace integration. Most people pick one and switch if it doesn't fit.
It is now close. Google AI Pro gives the Gemini app a 1M-token window (32K on Free). Claude Opus 5.5 and Sonnet 5.5 are 1M-token models, and OpenAI's GPT-6 models take 1.05M tokens on the API. The practical difference is how fast each plan's limits drain on long inputs, not the headline window — long documents use up Claude Pro's session allowance quickly.
