Sider Review — Multi-Model AI Sidebar for Research, Writing, and Analysis
Sider is an AI sidebar that gives access to ChatGPT, Claude, Gemini, DeepSeek, Grok, and other models from a panel that sits alongside any webpage. It handles summarisation, translation, PDF analysis, image understanding, and writing assistance without requiring separate tools or tab switching. It has over 8 million installs and is one of the most feature-complete AI sidebars available in 2026.

Sider provides access to multiple AI models — ChatGPT, Claude, Gemini, DeepSeek, Grok — from one sidebar that stays open alongside whatever you're browsing. Switching between models to find the one that performs best for a specific task takes one click.
The summarise-any-page function reads the current page's content and generates a summary on demand. For research-heavy creators scanning multiple articles, blog posts, or competitor pages, this replaces full reads with targeted summaries.
PDF analysis lets you upload a document to Sider and ask questions about its content directly. For creators reviewing media kits, partnership agreements, or industry reports, this removes the need to read documents from start to finish to find specific information.
Image understanding lets you share a screenshot or image with Sider's AI and ask questions about what it contains. Creators can describe a thumbnail to get feedback, or share a competitor's design for analysis.
Translation works inline — select text on any webpage and translate it to your language through the sidebar without opening a separate translation tool or tab.
Who Is It For
Creators who use multiple AI tools daily and want them consolidated into a single browser interface. Sider is particularly useful for research-intensive workflows where summarisation, translation, and AI chat all appear in the same session.
If you use one AI model consistently for all tasks and are satisfied with its dedicated interface, the consolidated sidebar adds less value. The Sider advantage is specifically multi-model access and cross-task flexibility in a single panel.
Pros and Cons
- ✅ Access to the widest range of AI models in one sidebar
- ✅ PDF and image analysis without separate tools
- ✅ Translate and summarise features work on any page
- ❌ Free tier query limits run out quickly with heavy daily use
- ❌ With many features enabled, the sidebar can feel cluttered for users who only need basic chat
Pricing
The free plan provides limited daily queries across models — enough to evaluate but not for heavy daily use. Paid plans start at approximately $8/month for expanded query limits. The premium plan unlocks higher-tier models and removes daily limits.
Summary
One of the best multi-model AI sidebars available for creators who actively use AI tools in their research and writing. The breadth of model access and the practical features (PDF analysis, image understanding, translation) make it genuinely useful across multiple workflow types. The free plan is worth testing to see whether the feature set matches how you work.
