Use Case Recommendations

Best for: HARPA AI

HARPA AI is a Chrome extension that puts a browser agent on every page you visit and lets you drive it with a single keyboard shortcut. Pressing Alt+A opens a side panel that can talk to GPT-5.4, Claude 4.6, Gemini 3.1 Pro, DeepSeek, Perplexity, Grok and Llama, either through your own API keys or through web session connections that reuse subscriptions you already pay for. The distinguishing piece is the automation engine sitting underneath the chat: HARPA is a hybrid browser-automation and LLM system, so it can scrape structured data off a page, monitor a URL for changes on a schedule, watch for price drops or back-in-stock events on e-commerce sites, and fire the results into Make.com, Zapier or n8n. On top of that it ships over 100 page-aware prompt automations grouped by job — marketing and SEO, e-commerce, copywriting, recruiting, learning — plus specific assistants for YouTube summarisation, Gmail triage and reply drafting, and long-form article generation across 25 writing frameworks. Quick shortcuts behind a // trigger cover finishing a draft, grammar, rephrasing, translation, search and explanation. Privacy is a stated design constraint: HARPA supports local models such as Llama, does not log conversations or actions, and is GDPR compliant. Pricing runs on a token balance rather than a message cap, with a lifetime option for single users.

Ideal use cases:

  • Teams or individuals who need alt+a side panel across gpt-5.4, claude 4.6, gemini 3.1 pro, deepseek, perplexity and grok
