What HARPA AI is
HARPA AI can summarize and query pages, run prompt workflows, monitor changes, and automate supported browser tasks. It is more configurable than a simple chat sidebar and correspondingly more complex.

- Reusable commands and automations
What stands out
- Distinctive automation layer
- Strong public rating

Tradeoffs to know
- Steeper learning curve

Permissions and privacy
Page access
Browser AI assistants may read the active page and selected text to generate a response. Check the current host permissions and avoid submitting private course, client, or account data.
Data notes
AI features may send prompts and page context to remote models. Treat the developer policy, model-provider terms, retention settings, and school or workplace rules as part of the product decision.
Pricing
Free tier with paid plans and usage limits. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
