About each tool
Claude Pro
Anthropic's paid personal Claude plan: more usage than Free, plus Research, unlimited Projects and Claude Code. $17 a month billed annually ($20 monthly).
Who it is for
Individuals who want more usage than the Free plan allows. Anthropic also positions it for longer multi-step tasks and for using Claude Code in the terminal under the same subscription.
Strengths
- Anthropic's pricing page lists Pro as everything in Free plus more usage, Research, unlimited Projects, Claude Code, more models, Claude in Chrome and Microsoft 365
- Pro is listed at $17 a month billed up front at $200 a year, or $20 a month if billed monthly
- Anthropic's help center says Pro offers at least five times the usage per session of the Free service, with priority access in high-traffic periods and early access to new features
- Documents added to a project are cached, and Anthropic says cached tokens count less toward usage limits than uncached ones
- Anthropic's Pro help article says subscribers can turn on usage credits to keep working beyond the included limits
Limitations
- Usage is limited by session and by week, not by a fixed message count. The session limit resets every five hours, and a weekly limit across all models resets at a fixed time assigned to the account
- Anthropic says message counts vary with message length, attached file length, conversation length and the model or feature used, and that it may add weekly or monthly caps or model and feature restrictions to manage capacity
- Usage limits are shared across Claude and Claude Code on Pro
- API usage is not included in Pro and needs separate Console billing
- Anthropic's privacy article says that if the training setting is on, chats from consumer plans (Free, Pro and Max) may be kept in de-identified form for up to 5 years
