Chat assistants · alternatives
Main reason people look elsewhere: Free-tier usage limits are not quantified; higher usage requires a paid Microsoft 365 plan.
"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 Microsoft Copilot profile.
| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| Microsoft Copilot (this page) | $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. |
| 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. |
| Google Gemini | $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. |
| 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. |
| Notion AI | $12/mo (Plus) | Yes | Web, Desktop, Mobile | Full AI needs Business or Enterprise, and even there a rolling six-hour and monthly usage allowance applies; premium models, Custom Agents and Workers consume separately purchased Notion credits. |
