## 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

## ScrollLess

ScrollLess tackles a very specific annoyance: ChatGPT answers are long, and threads get very long, so scrolling back to find what you actually asked becomes slow and tedious. The extension adds a toggle that hides every model response in the conversation, leaving only your prompts as a fast, scannable index. From there you can click any individual prompt to expand just that response, or configure the extension to auto-hide responses whenever a conversation loads.

**Pricing & Plans:** Free to install from the Chrome Web Store. There is no paid tier, subscription or account requirement.

- **One-shortcut hide/show all:** Press the extension shortcut to hide every ChatGPT response in the thread at once, and press it again to bring them all back.
- **Click a prompt to expand its answer:** With responses hidden, your prompts become the navigation bar; click any one to reveal only the reply you need.
- **Auto-hide on load:** A setting in the extension options makes responses collapse automatically every time a conversation opens, so long threads are always compact.
- **Conversation export:** Save a thread as plain text or JSON, which is handy for keeping notes or moving a conversation elsewhere.
- **YouTube transcript export:** Grab the transcript of the currently playing video, with or without timestamps, straight from the extension.

**Strengths:** Free with no account and a very small install footprint; Cuts scrolling dramatically in long ChatGPT conversations; Auto-hide setting means the thread loads compact every time; Bonus YouTube transcript export with optional timestamps

**Limitations:** Depends on ChatGPT's page structure and may break when that interface changes; Developer says it has not been tested on ChatGPT Plus or custom GPTs; Small user base and last updated in August 2025
