HARPA AI
HARPA AI runs GPT-5.4, Claude Sonnet 4.6, Gemini 3.1 Pro and more on any web page with Alt+A in your browser.
Buy this if your AI work happens inside web pages and inboxes, not in a chat window. The price-drop monitors, page watchers, form-fill automations and Zapier/Make.com/n8n triggers are things ChatGPT Plus, Claude Pro or Gemini can't do in your browser, and one subscription spanning seven models beats stacking them. Just budget your Megatokens carefully — heavy automated use burns through them.

Skip HARPA AI if your security policy blocks browser extensions with full page access, or if you only ever use one chat model and have no interest in page monitoring, form filling or Zapier/Make.com/n8n automation.
Everyone's 75 Megatokens/year runs out faster than a flat subscription suggests, and after that your only options are €25.5 Top Ups for 20 Megatokens, free web sessions or your own API keys.
At €14.3/mo billed annually (Everyone) and €19.6/mo billed annually (Pro), HARPA undercuts stacking ChatGPT Plus $20/mo, Claude $20/mo, Gemini $20/mo, Grok $30/mo and Perplexity $20/mo — its own comparison. It suits solo professionals and small teams; large teams wanting admin controls and pooled usage should price Team seats (extra seats at 10% off on Pro) against a multi-model workspace subscription instead.

What is HARPA AI?
HARPA AI — HARPA AI runs GPT-5.4, Claude Sonnet 4.6, Gemini 3.1 Pro and more on any web page with Alt+A in your browser. Best for Professionals juggling several LLMs who want one subscription and one keyboard shortcut, Marketers and SEO specialists running audits, keyword research and long-form article generation, Ecommerce shoppers and sellers tracking prices and restocks across Amazon, AliExpress, Walmart and eBay. Plans from €14.30/mo billed annually.
HARPA AI is a browser extension for Chrome, Edge and Brave that turns any web page into a working surface for multiple cloud LLMs. Hit Alt+A and you get GPT-5.4, Claude Sonnet 4.6, Gemini 3.1 Pro, DeepSeek V3, Perplexity Pro, Grok 4.1 and Llama 4 in one assistant that can already read the page in front of you. It's aimed at people whose work lives in tabs: marketers, SEOs, recruiters, ecommerce sellers, developers and anyone drowning in email and long documents. The page-aware part is what separates it from a chat tab. It summarizes hours-long YouTube videos with jumpable timestamps and lets you question the video, compiles cited answers next to Google Search, categorizes Gmail and drafts replies in your own voice, and writes articles of 25,000+ words across 25 frameworks with keyword refinement at every step. A Midjourney wizard generates detailed image prompts from 30+ presets, and a language wizard builds study plans and explains grammar. Beyond reading, HARPA acts. Set a web page monitor for change alerts, track price drops and restocks on Amazon, AliExpress, Walmart and eBay, scrape listings and prospects, fill forms, and drive the browser remotely from Zapier, Make.com or n8n. You can build custom GPT agents with page, search and automation access, reuse 100+ page-aware prompts, and lean on single-key shortcuts (F to finish, G for grammar, P to rephrase, T to translate). The vendor states it runs locally, doesn't log conversations, is GDPR compliant, and works with bring-your-own API keys or web session connections to ChatGPT, Claude and Gemini. Against a single-model $20/mo subscription, HARPA's pitch is breadth plus browser automation in one bill.

Behind the verdict
We'd reach for HARPA when the job is 'do something with this page right now.' Summarizing a 90-minute YouTube video, pulling long-tail keywords out of a competitor's article, watching a product page for a restock, or clearing a Gmail backlog with tone-matched drafts — that's the sweet spot, and it's genuinely faster than copy-pasting into a chat app. The automation layer is the real differentiator. A page monitor that pings you on change, price tracking across Amazon, AliExpress, Walmart and eBay, and remote browser control from Zapier, Make.com or n8n are capabilities a plain chat subscription doesn't offer. If you already wire up IFTTT-style chains, HARPA slots in as the AI step. Where it bites: everything runs on Megatokens. Everyone gets 75 per year at €14.3/mo billed annually, Pro gets 225 at €19.6/mo billed annually, and heavy automation eats them fast, so budget for €25.5 Top Ups (20 Megatokens at a stated 25% discount). Scheduled commands and advanced automation are Pro-only — if you want recurring jobs, Everyone is the wrong tier. Pass if you need one great model and nothing else, or if your security team blocks extensions with full page access. HARPA reads everything you point it at, which is the product and also the risk. Teams with strict data policies should check the privacy terms before deploying. Against ChatGPT Plus or Claude Pro at $20/mo, HARPA wins on model breadth and browser context, loses on raw model depth and polished chat UX. We'd frame it as a productivity add-on rather than a replacement. The €238 Life tier (30 Megatokens, unlimited web session connections, scheduled commands, advanced automation) is the value pick if you're confident you'll stick with it.
Models under the hood
as of 2026-10-23
Limitations
- Token allocations are the constraint to plan around: Everyone carries 75 Megatokens/year, Pro 225 Megatokens/year, and the Life tier bundles only 30 Megatokens.
- Extra usage comes from Top Ups (€25.5 one-time for 20 Megatokens), free web session connections, or your own API keys.
- Scheduled commands and advanced automation are not included on Everyone — they require Pro or Life.
- Life is single-user only, so it does not scale to a team.

GeneratedReal-world workflow fit
Concrete scenarios for the personas HARPA AI actually fits — and what changes day-one when you adopt it.
Open a competitor article, press Alt+A to pull its structure, extract long-tail keywords, then generate a 25,000+ word draft in a chosen framework with keyword refinement at each chapter.
Outcome: A publishable long-form draft and keyword report in one browser session, without exporting between a chat tool and a doc.
Set the page monitor on Amazon, AliExpress, Walmart or eBay listings, then let HARPA re-check for price drops and restocks and notify on change, with a Zapier or n8n trigger firing when it updates.
Outcome: Timely price and stock alerts pushed into your existing automation stack instead of manual daily checks.
Run the Gmail assistant to categorize incoming mail, summarize long threads, and draft replies that mimic your writing style, using F to finish and G to check grammar on each draft.
Outcome: A cleared inbox with on-voice replies, at the cost of the Megatokens each pass consumes.
Use cases

Setup time & first value
How long it actually takes to get something useful out of HARPA AI — broken out by persona, not the marketing-page minute.
Install the extension and sign in: a few minutes to first page summary. Connecting web sessions for ChatGPT, Claude or Gemini takes another few minutes. Budget an hour to build a first custom GPT agent or a price-monitor automation, and a few hours to wire Zapier, Make.com or n8n triggers — after which runs are scheduled.
Switching to or from HARPA AI
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From ChatGPT Plus: add the HARPA extension, connect your ChatGPT web session or API key, and press Alt+A instead of opening the ChatGPT tab.
- →From a standalone summarizer extension: install HARPA and map its page-aware prompts and YouTube summarizer to your existing reading workflow.
- →From Zapier-only monitoring: move the page check into HARPA's monitor and use Zapier or n8n only for the downstream action.
- ↗To a single-model chat subscription: export the prompts you actually reuse as reusable commands before leaving, since chat history stays behind.
- ↗To a dedicated automation platform: port page-monitor and form-fill steps into n8n or Make.com scenarios and keep HARPA only for ad-hoc page chat.
