## HARPA AI

HARPA AI positions itself as a browser agent rather than just a chat sidebar. Press its keyboard shortcut on any web page and you get a choice of frontier models — GPT, Claude, Gemini, Perplexity, DeepSeek among others — plus ready-made prompts that understand the page you are on. That page awareness is the differentiator: it can summarise a long article or PDF, answer alongside search results with citations, draft a reply in your own writing style, or explain an error message in context rather than in the abstract.

Alongside the assistant features sits a real automation layer. HARPA can monitor web pages for changes, watch e-commerce listings for price drops and restock alerts, scrape structured data from sites, and chain actions into Zapier, Make.com or IFTTT. You can drive the browser remotely from those tools, which turns the extension into an automation worker rather than a passive helper. Custom GPTs and team agents can be brought into the browser with access to page content, search and automation functions.

HARPA markets itself on privacy: it runs locally in the browser, does not log conversations and actions, is GDPR-compliant, and can be pointed at local models such as Meta Llama or at your own API keys. It has a free tier and a short premium trial, with paid plans starting around $12 per month billed annually that add CloudGPT access, cloud command storage and chat history. The extension is aimed at professionals and teams who want AI assistance and automation on the sites they already use, without switching tools.

**Pricing & Plans:** HARPA AI has a basic free tier plus a demo period for premium features. Paid plans start around $12 per month when billed annually, adding CloudGPT connectivity, cloud command storage and chat history. Bring-your-own API keys (OpenAI, Claude, Gemini, OpenRouter) are also supported.

- **Multi-model access:** Switch between GPT, Claude, Gemini, Perplexity, DeepSeek and other models from one extension on any page, without juggling separate tabs or subscriptions.
- **Page-aware prompts and summarising:** Summarise long articles, PDFs and YouTube videos, ask follow-up questions about the content, or jump to the relevant timestamp in a video.
- **Web monitoring and price tracking:** Track page changes, price drops and back-in-stock alerts across e-commerce sites, with notifications when something moves.
- **Scraping and automation:** Extract structured data from websites, fill forms, click through flows and trigger Zapier, Make.com, IFTTT or n8n chains.
- **Writing in your voice:** Draft emails, replies, posts and long-form articles that mimic your own writing style, with grammar, rephrase and translate shortcuts.

**Strengths:** Access to several frontier models from one extension instead of separate subscriptions; Genuine automation: page monitoring, price tracking, scraping and form filling; Page-aware prompts that work with the content you are actually reading; Privacy-oriented: no conversation logging, local execution, GDPR compliance

**Limitations:** Generative features depend on connecting an AI provider or the paid CloudGPT; Chrome-extension based, so it is tied to Chromium browsers; The breadth of features takes time to learn and configure

## Scouter - Language Learning

Scouter - Language Learning is a browser extension built around a simple idea: language acquisition works best when you meet words in real context rather than in isolated vocabulary drills. Instead of copying sentences into a separate study app, you keep reading, watching and browsing, and Scouter breaks down what is in front of you, explains how words behave in that specific sentence, and offers images or dictionary lookups that make the meaning stick.

The extension summarizes webpage content, works with YouTube videos, and accepts custom prompts so you can shape how explanations are produced. Vocabulary you decide to keep goes into Anki in one step, complete with pronunciation, phrase and example sentence, so the bridge between passive exposure and spaced-repetition review stays short. A multilingual interface and one-on-one customer support via its Discord community round out the experience.

Scouter supports a range of model backends, including GPT-4, Claude and locally run Ollama models, alongside free online dictionaries, which lets privacy-conscious users or anyone with an existing API key keep their setup affordable. It is distributed through the Chrome Web Store as a free extension with optional paid capability, and it sits in the language-learning category alongside tools like Lingoku and LiveLang.

**Pricing & Plans:** Listed as freemium on the Chrome Web Store: the extension can be installed at no cost, and paid options unlock expanded usage. Check the extension listing for current tiers.

- **Contextual word explanations:** Understand how a word is used in a specific sentence from the page or video you are reading, rather than relying on a generic dictionary definition.
- **One-click Anki export:** Send words, pronunciations, phrases and full example sentences to Anki without leaving your reading flow.
- **Learn from YouTube:** Watch videos in your target language and pull vocabulary directly from the subtitles and content on screen.
- **Multi-model support:** Choose between GPT-4, Claude, local Ollama models and free online dictionaries, so you can match cost, privacy and quality to your needs.
- **Custom prompts:** Define your own instructions for how explanations and summaries are generated, tailoring the study method to your level and goals.

**Strengths:** Fits into reading and video watching instead of adding a separate study session; Direct Anki integration with pronunciation and example sentences; Choice of GPT-4, Claude, Ollama or free dictionaries; Actively maintained extension with a public update history

**Limitations:** Requires Anki for the full spaced-repetition workflow; Advanced usage depends on bringing your own model access; Available only in Chrome, so Safari and Firefox users are left out
