Sider

Paid

Sider sits in your browser sidebar and lets you ask AI about whatever page you are on. It reads the page for you, so you do not need to copy and paste text between tabs.

You pick from a handful of models—GPT, Claude, Gemini, DeepSeek, and others—and run them side by side. It also turns research into formatted documents and builds simple websites or slides from a prompt.

The tool lives in the Chat & Assistants category. It works best for quick lookups and browser-heavy work, not for deep file management or offline tasks.

Open it if you want AI in your browser without opening new tabs. Skip it if you need to organize long conversation histories or export research as PDF.

These are the people who get the most use out of it.

• Writers and researchers needing quick AI access without tab switching: You keep your flow. The sidebar slides open, answers your question, and stays out of the way.
• Users who want to compare outputs across multiple AI models: You run the same prompt through GPT, Claude, and Gemini at once. You pick the best answer without logging into three sites.
• YouTube heavy users wanting video summaries: You paste a link or open a video, and Sider gives you the key points before you commit to watching.
• Students needing quick summaries and research help: You highlight dense text and get an explanation or draft reply without leaving your assignment tab.
• Multilingual professionals who translate content frequently: You translate across 50+ languages and compare how different models handle the same phrase.
• AI explorers wanting to test multiple models without managing separate subscriptions: You try Claude, Gemini, and DeepSeek from one account instead of paying for each.
• Users needing quick simple websites or presentations: You type a prompt and get a working page or slide deck, no code needed.
• Researchers and analysts wanting multi-source reports: You enter a topic and get a structured document with sources and notes in minutes.

These are the parts you notice after using it for a while.

• Browser sidebar that eliminates tab switching: The AI stays docked while you browse. You do not lose your place or clutter your tabs.
• Access to 10+ major AI models in one place: You bounce between Claude 3.7 Sonnet, GPT, Gemini, and others without separate logins.
• Deep Research that builds structured docs: You get a formatted report with sources and AI notes, ready to reference or rewrite.
• Context-aware help on any page: You highlight text and choose Summarize, Explain, or Reply. It knows what you are looking at.
• Stable daily use: One user reported zero crashes or downtime over five months of regular use.

The path is short once it is installed.

1. Install the extension and sign in. A floating icon appears at the bottom-right of your browser.
2. Click the icon to open the sidebar while you are on any webpage, PDF, or YouTube video.
3. Select your AI model or let it read the current page for context.
4. Type your question or pick a quick action like Summarize, Translate, or Explain.
5. Read the output, start a follow-up, or switch models to compare answers.

Skip it when the limits get in your way.

• Credits expire monthly with no rollover: You pay for a tier, do not use it all, and the remainder disappears. You feel burned.
• "Unlimited" has hard caps: Your plan says unlimited, but quality drops after 1,500 to 10,000 credits. You hit a wall mid-project.
• No conversation organization or search: You cannot sort chats into folders, search old threads, or export your history. Past work is hard to find.
• Research reports stuck in HTML: You build a nice interactive report, but you cannot download it as PDF or image. You recreate it manually to share.
• Desktop apps skip document upload: You install the Windows or Mac app and find you cannot upload files there. You must use the browser.
• Support blocks cancellations: You request a refund or cancellation and get ignored. You pay for another month you did not want.
