Sider: AI Chat Assistants for Consumers and Shoppers
A shopper comparing gaming PC parts across five browser tabs loses track of which site had the better GPU price. Sider is a browser sidebar, a AI Chat Assistants tool, that reads the open page and chats or automates on command. Strong at summarizing content across tabs — not built for one fixed, verified model.

What Sider Does
Sider solves tab-switching fatigue by putting chat, automation, and content tools inside the browser itself.
The sidebar connects to GPT, Claude, Gemini, Grok, and DeepSeek so a user can summarize a webpage, translate a PDF, or ask follow-up questions without opening a separate AI site. Sider’s Hand feature extends this into action: it compares prices, fills forms, and pulls data from sites like Amazon or Best Buy on its own. Code lets a user rewrite how a site looks and keeps that change for the next visit, turning a one-off tweak into something persistent.
Main Features
Chat
Chat lets a user summarize, explain, translate, or ask questions about any content open in the browser, including web pages, PDFs, and YouTube videos. Sider routes the request to GPT, Claude, Gemini, or another connected model. The output appears in the same sidebar, so the source material never has to be copied out to a separate chat window.
Hand
Hand runs browser tasks on real websites: researching, comparing prices, extracting data, and organizing results across the pages a user already has open. It uses a dedicated cloud computer on paid plans to keep tasks running in the background. That separation means Hand tasks continue even if the browser tab is closed.
Code
Code edits, restyles, or simplifies any website in plain language and saves the change for the next visit. Sider applies the edit client-side rather than modifying the original site. Because the preference is stored per user, a customized layout or simplified page persists across sessions without being reapplied each time.
Mobile & Extension Access
Sider ships as a Chrome and Edge extension plus native apps for iOS, Android, Mac OS, and Windows. A chat or research session started on desktop stays accessible from a phone through the same login. This matters for users who switch devices mid-task, such as finishing a product comparison started at a desk from a phone in-store.
Use Cases
-
Gaming PC Price Comparison
Consumers and shoppers building a gaming PC use Sider’s Hand feature to compare GPU, CPU, and motherboard prices across Amazon, Best Buy, and eBay in one pass. This replaces manually reloading tabs to track price changes.
-
YouTube Video Summarization
Content consumers use Sider’s YouTube Summary tool to get key points from a video without watching it in full. Chat extracts the transcript and condenses it inside the sidebar, saving a screening step before committing time.
-
PDF Analysis and Q&A
Students and researchers use ChatPDF inside Sider to ask direct questions about a document instead of reading it end to end. The AI-powered Q&A answers from the PDF’s own content, narrowing a long paper to relevant sections.
Best For / Not For
Sider is built for people who need an AI layer on top of browsing itself, not a standalone chat app.
Consumers and shoppers comparing prices across retail sites, content consumers who want video or article summaries before committing time, and students and researchers working through PDFs or academic sources all fit the tool’s design.
Sider is not built for teams needing a single verified model with audit trails, since it routes requests across multiple third-party AI providers rather than standardizing on one; enterprises with strict compliance requirements should look elsewhere.
Pricing
Sider’s entry paid plan, Nano, costs $10 / user/month, billed monthly, and includes Chat, Hand, Code, and Create with a temporary cloud computer.
| Plan | Price | Included |
|---|---|---|
| Nano | $10 / user/month, billed monthly | |
| Lite | $25 / user/month, billed monthly | |
| Pro | $50 / user/month, billed monthly | |
| Max | $100 / user/month, billed monthly |
The table does not show what happens once monthly credits run out mid-cycle, or whether unused credits roll over.

Quick Comparison
Qwen AI is Sider’s main alternative for users who want multi-purpose chat without a browser-extension dependency. Qwen AI runs as a standalone model with its own training and does not require a browser sidebar to function. Sider’s advantage is its Hand automation, which extracts and compares data directly from live retail pages like Amazon and Best Buy. Choose Qwen AI if a standalone chat interface without browser integration fits the workflow better. Choose Sider if the task requires acting on pages already open in the browser.
Verdict
Sider runs Chat, Hand, and Code across four tiers starting at $10 / user/month, billed monthly, giving shoppers and researchers one sidebar for summarizing, comparing, and editing browser content. It fits consumers and students more than enterprise teams needing a single compliant model.
