Limits and trade-offs
['No authenticated product test was performed; automation reliability across sites was not independently verified', 'Generative features require a separate AI provider connection, so total cost includes that provider where applicable', 'Some sites and browsers are limited: the homepage notes it does not work with Google Sheets yet and has no Firefox version']

A closer look at HARPA AI
HARPA AI is a browser extension combining ChatGPT, Gemini, Claude, Perplexity and DeepSeek with web automation. It can summarize and talk to web pages, YouTube videos and PDFs, write and reply to emails, extract data, research SEO keywords, fill forms and run multi-step AI commands that navigate pages and trigger tools such as Zapier. Generative features need an AI provider connection; a basic free tier is offered alongside an S plan from $12 a month paid annually with CloudGPT access.
Editorial guidance based on published documentation. The workflow below is a suggested starting point, not a measured product result.
When to choose HARPA AI
- Browser-heavy workers who want AI summaries, replies and data extraction on any website
- Marketers and researchers tracking competitors, prices, SERP pages and SEO keywords
- Users who want reusable multi-step automations that navigate pages and trigger tools such as Zapier
When to choose something else
- Firefox users, since the homepage states no Firefox version is available at the moment
- Anyone wanting a fully standalone app rather than a browser extension tied to provider accounts or keys
A practical starting workflow
- Install the browser extension and connect an AI provider, such as a ChatGPT account, API key or CloudGPT
- Open any website and ask HARPA to summarize the page, video or document, or to extract data from it
- Use built-in commands or build custom AI commands that chain navigation, extraction and model steps
- Run automations such as monitoring, form filling or content drafting, and trigger external tools where configured
Check before committing
- Vendor claims on the homepage, including speed, reliability and privacy, are marketing statements, not guarantees, and were not independently tested
- Prices and features may change; model availability such as GPT-5.4 access depends on the plan and provider and should be confirmed before paying
- Source basis is thin: only the official homepage was reviewed, with no authenticated product test, extension install or automation run
