Chat assistants · alternatives
Three Gemini traits send people elsewhere. Usage limits are compute-based, refresh every 5 hours up to a weekly cap, and Google says they may change, so you cannot count prompts. On free consumer accounts with Keep Activity on, chats are used to train Google models and a subset is read by human reviewers. The Free plan also has a 32k-token context window. Many features are 18+ or select-country only. Paid tiers start at Google AI Plus, $4.99/mo, and Pro is $19.99/mo.
ChatGPT has a free plan and Plus at $20/mo, with message caps during high demand. Claude has a free plan and Pro at $20/mo, with usage limits. Perplexity is an answer engine that cites sources; its listed entry is Education Pro at $10/mo for verified students and faculty, with a free plan. Microsoft Copilot suits Microsoft 365 users: it has a free tier and Microsoft 365 Personal at $9.99/mo.
"Better suited" below is based on documented features and pricing from our verified profiles, not on a head-to-head test. Prices are USD as published by each vendor.
Taken from the documented limitations in our Google Gemini profile.
| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| Google Gemini (this page) | $4.99/mo (Google AI Plus) | Yes | Web, Desktop, Mobile | Usage is governed by compute-based limits that refresh every 5 hours up to a weekly cap, and free-tier chats with Keep Activity on are used to train Google models with human review. |
| ChatGPT | $20/mo (Plus (consumer)) | Yes | Web, Desktop, Mobile, API | Almost every tool (uploads, images, voice, deep research, Codex) has plan-dependent usage caps that OpenAI states can change over time, and the API is billed separately from every ChatGPT subscription. |
| Claude | $20/mo (Pro) | Yes | Web, Desktop, Mobile, API | All plans have usage limits that reset on a schedule; the paid chat subscription does not include API access, which is billed separately per token. |
| Perplexity | $10/mo (Education Pro (consumer, verified students/faculty)) | Yes | Web, API | The consumer pricing page is blocked to automated checks, so the Pro price could not be confirmed here, and free-tier Pro Search and Research access are described only as 'very limited' / 'limited'. |
| Microsoft Copilot | $9.99/mo (Microsoft 365 Personal) | Yes | Web, Desktop, Mobile | Free-tier usage limits are not quantified; higher usage requires a paid Microsoft 365 plan. |
| Alternative | Pick it when | Starting price | Watch out for |
|---|---|---|---|
| ChatGPT better suited to users outside the Google ecosystem wanting a general assistant |
You do not rely on Gmail/Drive grounding | $20/mo (Plus (consumer)) | No bundled Google storage or Workspace integration |
| Claude better suited to long-form writing and coding with a no-training-by-default posture |
Privacy defaults matter more than Google app integration | $20/mo (Pro) | No image or video generation |
| Perplexity better suited to citation-first web research |
You mainly want sourced answers rather than creative or agentic tasks | $10/mo (Education Pro (consumer, verified students/faculty)) | Narrower creative toolset |
| Microsoft Copilot better suited to Microsoft 365 users |
Your mail, files and calendar live in Outlook and OneDrive | $9.99/mo (Microsoft 365 Personal) | Weaker tie-in to Google services |
