## 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

## Sider

Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
- **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans
