Harpa.ai - 2026 Pricing, Features, Reviews & Alternatives

Harpa.ai is a Chromium-based browser extension that integrates multiple large language models with a web automation engine, delivering AI-assisted browsing, writing, data extraction, web monitoring, and workflow automation directly inside the browser on any website. It connects to providers including OpenAI GPT, Anthropic Claude, Google Gemini, xAI Grok, Perplexity, DeepSeek, and Meta Llama, supporting web session connections, user-supplied API keys (BYOK), and a managed CloudGPT connection. Browsing data is processed locally and not stored on vendor servers, with optional cloud sync for chat history and command storage on paid plans. Trusted by 500,000+ professionals and teams, it targets individual professionals, freelancers, digital marketers, SEO specialists, content creators, developers, e-commerce sellers, and organizations of all sizes.

The extension's page-aware AI chat reads live web page content and sends it to the selected LLM for summarization, Q&A, and analysis, grounding responses in real-time context. Over 100 prebuilt commands cover writing, SEO, email, coding, and research, while custom AI commands allow user-defined automation sequences with parameterized prompts. Additional capabilities include YouTube video summarization with timestamps, PDF and image analysis via drag-and-drop or screen capture, AI Vision for visual question answering and code explanation, and AI-assisted search results across Google, Bing, and DuckDuckGo. Web and price monitoring runs in the background without consuming CPU when idle, sending notifications on content or data changes.

For teams and enterprise workflows, Harpa.ai offers Team Spaces with shared command storage, locked commands, and shared AI connections across an organization. The GRID API provides a browser orchestration REST API for triggering AI prompt execution from external services. Webhook-based integrations connect to Make.com, Zapier, n8n, Microsoft Power Automate, and 1000+ other apps. MCP tool server connections extend AI connections to external tools. Scheduled AI command execution, data scraping via CSS, XPath, or text selectors, SEO audit and keyword tools, and email thread management round out the platform's feature set. The interface is available in 14 languages, with a free tier, subscription plans, and a one-time lifetime purchase option.
