## 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

## xData

xData is a Chrome browser extension that acts as your gateway into the DIN ecosystem, described by its developer as a modular, AI-native data pre-processing layer. The core idea is simple: while you browse X (Twitter), the extension lets you gather content data that feeds decentralized AI development, and it rewards you with $Wafer tokens for participating.

The extension positions ordinary web users as participants in AI data pipelines. Rather than hand over data invisibly, users choose to collect it and are compensated for the contribution. xData advertises a user-friendly interface and a secure collection environment, aiming to lower the barrier for anyone who wants to take part in shaping AI development.

xData is a third-party tool and is not affiliated with, endorsed by, or produced by X (Twitter) or any AI model provider. Token rewards, availability, and network mechanics can change, so treat the extension as an independent Web3 experiment and review its data-handling disclosures before installing it.

**Pricing & Plans:** xData is free to install and use. Instead of charging a subscription, it uses a token-reward model: users who collect data through the extension earn $Wafer tokens as part of the DIN ecosystem.

- **One-click data collection on X:** Collect content data directly on X (Twitter) while you browse, without leaving your normal workflow.
- **$Wafer token rewards:** Get compensated in $Wafer tokens for the data you contribute to the DIN network.
- **Gateway to the DIN ecosystem:** The extension plugs your browser into DIN, a modular AI-native data pre-processing layer.
- **Simple, secure interface:** A lightweight, user-friendly Chrome extension designed to make data contribution accessible.

**Strengths:** Free to install with a token-based reward model rather than a subscription; Simple one-click workflow that fits into regular browsing on X; Connects directly to the DIN decentralized data ecosystem

**Limitations:** Reward value depends on the volatile $Wafer token; Requires handing over browsing-activity and page-content data; Not affiliated with X (Twitter), so functionality can break when the platform changes
