Sider

Sider is an AI-powered assistant that works directly on top of any webpage, helping you read, write, research, and create—all without leaving your browser. It brings together multiple advanced AI models, including ChatGPT-3.5/4, Claude 3, and Gemini 1.5 Pro, into one seamless side panel. Whether you need to summarize an article, rewrite a paragraph, chat with a PDF, or generate an image, Sider acts as your always-available digital sidekick, designed to boost productivity and spark creativity across a wide range of online tasks.

• Multi‑model AI hub: Combines ChatGPT-3.5/4, Claude 3, and Gemini 1.5 Pro in one tool, letting you switch between or compare models for any task.
• Read & write on any webpage: Summarize, explain, or translate text; draft emails, social posts, or articles right where you are—no copy‑pasting needed.
• Chat with links, images, and PDFs: Upload files or share a URL, then ask questions, extract insights, or generate content based on the source material.
• Integrated image generator: Create visuals and designs from text prompts without juggling a separate design tool.
• Group AI Chat: See responses from multiple AI models side by side in a single chat view, helping you pick the best answer or get diverse perspectives.
• Quick‑action context menu: Highlight any text on a webpage to instantly summarize, rewrite, explain, or translate it—speed up comprehension and editing.
• Chat‑based PDF reader: Open a PDF in the browser and converse with its content, extracting key points or searching for specific information without manual scanning.

1. Install the extension: Go to the Chrome Web Store or Edge Add‑ons, search for “Sider,” and add it to your browser. A side panel icon will appear in your toolbar.
2. Open the assistant: Click the Sider icon (or use the keyboard shortcut) to open the side panel. The panel works on any tab you’re currently viewing.
3. Choose your AI model: From the dropdown, select which model you want to use—ChatGPT‑4, Claude 3, Gemini 1.5 Pro, or Group AI for multi‑model answers.
4. Interact with the page: Highlight text on the webpage to see quick‑action buttons (summarize, explain, rewrite, translate). Click any action to get an instant result in the side panel.
5. Upload files or links: Drag a PDF, image, or paste a URL into the chat input. Then ask questions or give instructions based on that content directly.
6. Refine your results: Continue the conversation—ask for edits, change the tone, or request a different format. You can also use the image tool by typing a prompt like “design a minimalist logo for…”

Sider offers a free tier that grants access to core AI features—such as page‑assistance, basic chat, and the image tool—making advanced AI help accessible to anyone. The free plan may include usage limits or model restrictions typical of generative AI tools. For higher usage volumes, priority access to premium models, or team features, paid plans are likely available. Because pricing details evolve frequently, always check the official Sider website for the most current free‑tier limits and subscription options.

• Browser extension: Available for Google Chrome and Microsoft Edge, with the core AI panel, context menu, and all chat features.
• Web app (planned or limited): A standalone web application may be in the roadmap; currently the primary experience is extension‑based.
• iOS / Android apps: Mentioned as future expansions, allowing on‑the‑go access.
• Mac OS / Windows apps: Also on the horizon, promising deeper system integration beyond the browser.
• Group AI Chat (cross‑platform): The multi‑model comparison feature is accessible wherever you’re running the extension, keeping insights unified.

• Leverage Group AI for ideation: When you need a range of perspectives (brainstorming slogans, problem‑solving), activate Group AI Chat to compare multiple model outputs in one go.
• Use the context menu for speed: Instead of switching to the side panel, simply highlight text and use the floating action buttons. This dramatically cuts down friction on reading‑heavy pages.
• Experiment with model selection: Different models excel at different tasks—try ChatGPT‑4 for creative writing, Claude 3 for long‑form analysis, and Gemini for quick factual lookups.
• Feed Sider structured prompts: For complex tasks (like drafting a report), give clear instructions: “Rewrite this in a formal tone with bullet points” works better than just “Improve”.
• Upload source materials: When you need accurate answers, upload the relevant PDF or paste the article link rather than relying on the model’s general knowledge—Sider will base answers on that document.
• Keep conversations on‑topic: Use separate chat sessions for different projects to maintain context and avoid confusing the models.

• Content writers and editors who need real‑time rewriting, tone adjustments, and idea generation without leaving their publishing platform.
• Students and academics tackling research, summarizing papers, or clarifying complex concepts while reading online resources.
• Design and creative professionals looking for a quick‑access visual brainstorming companion that exists right in the browser.
• Remote workers and business professionals who juggle emails, reports, and cross‑lingual communication daily.
• Curious learners and heavy web users who value instant explanations, translations, and concise summaries of any webpage content.
• Small teams and solo entrepreneurs who want a versatile AI assistant without the cost or complexity of multiple separate tools.
