About Sider

What is Sider?

Sider is an all-in-one AI assistant that integrates directly into your browser, giving you access to powerful AI models like ChatGPT, Claude, and Gemini without leaving the page you're on. Whether you're reading an article, working on a document, or researching, you can open Sider's sidebar to ask questions, request summaries, translations, or even analyze images.

Key Features

  • Multi-model AI chat: Interact with GPT-4, Claude, and Gemini from a single interface, and choose the best model for your task.
  • Webpage summarization and Q&A: Get instant summaries of long articles and ask questions about the page content.
  • Writing assistance: Improve grammar, rephrase, translate, and generate text directly in any input field.
  • Image analysis and OCR: Extract text from images and analyze image content with AI.
  • Document interaction: Upload PDFs or documents and request summaries or answers based on their content.
  • Cross-platform: Available as a browser extension and apps for iOS, Android, Windows, and Mac.

How to use Sider?

After installing the browser extension or desktop app, a sidebar appears in your browser. Click the Sider icon to open the chat, then type your query or select text to translate or improve. You can also upload images and documents for analysis. Sider remembers conversation context and can refer to the current page to provide accurate answers.

Who is it for?

Sider is ideal for students, researchers, writers, translators, and professionals who need instant help with reading, writing, and analysis while browsing the web. It significantly boosts productivity by integrating AI into daily workflows.

AI Tools Oasis Team Review: Sider

After testing Sider, we found it to be an exceptional tool for integrating AI into daily web browsing. The sidebar is smooth and easy to use, and support for multiple models gives users great flexibility. The webpage summarization and Q&A feature is particularly useful for researchers and students. Image analysis and OCR work with good accuracy. The main drawback is that the free version is limited, and heavy users may need a paid subscription. Overall, Sider is worth trying for anyone looking to boost productivity while browsing.
