## adata-plugin

adata-plugin is a browser extension built for people who spend their days labeling data — text annotation, classification tasks, and other supervised-learning datasets. Instead of clicking through every item manually, the extension layers an AI-assisted workflow on top of the pages you already use, suggesting labels so annotators can accept, adjust, or override them rather than deciding from scratch.

The extension is distributed directly through the Chrome Web Store, installs in a single click, and requires no special hardware or account setup. It is offered by an individual developer (so.zuwei) and is currently listed as version 1.0.0, first published in July 2022, with a Chinese-language interface. The developer states that no user data is collected or sold, which matters for teams handling sensitive or proprietary datasets.

Because it is a compact utility rather than a full annotation platform, adata-plugin works best as a productivity layer on top of whatever labeling tool or spreadsheet your team already uses. It is a good fit for small annotation teams, freelance data labelers, and researchers who want a low-friction speed boost without migrating to an enterprise annotation suite.

**Pricing & Plans:** Distributed as a free Chrome extension with no published paid tier; any future premium capability would be handled by the developer directly.

- **AI-assisted labeling suggestions:** The extension proposes likely labels or annotations as you work, so you can confirm a suggestion instead of classifying each item from zero.
- **One-click Chrome install:** Runs entirely in the browser via the Chrome Web Store, with no server setup, plugin dependencies, or account creation required.
- **Fits your existing workflow:** Acts as a companion layer over the annotation pages you already use, so there is no need to migrate your dataset or tooling.
- **Privacy-conscious design:** The developer declares that user data is not sold or shared and is not used for unrelated purposes.
- **Lightweight footprint:** A small (~3.4 MB) extension with a Chinese-language interface, aimed at keeping annotation sessions fast and distraction-free.

**Strengths:** Free to install and use directly from the Chrome Web Store; Requires no account, backend, or technical configuration; Developer explicitly states user data is not collected or sold; Speeds up repetitive labeling work without replacing your existing annotation tool

**Limitations:** Small independent project with no ratings or reviews to gauge reliability; Last updated in 2022, so it has not tracked newer browser or AI model changes; Interface is only available in Chinese, limiting accessibility for other-language teams; Very narrow scope — it assists labeling but is not a full annotation platform

## 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
