Our verdict on Sider
Sider brings multi-model AI chat into browsing, reading, writing, and document workflows. It is aimed at individuals and teams who want to switch among models such as GPT, Claude, Gemini, and Grok while working with web content. Access is available through a browser extension, desktop apps, and mobile apps, so it can suit people who move between devices. Those looking only for a focused chatbot may find its mix of research, writing, and browser utilities broader than they need.
Its feature set reaches beyond conversation: Sider can summarize webpages, YouTube videos, and documents; search the web; analyze uploaded files and images; translate PDFs; and assist with writing, OCR, and grammar. Image generation and editing add another use case, while Sider Hand automates browser tasks. Integrations include Gmail, Slack, Notion, Microsoft Office apps, Apple apps, Obsidian, Safari, and Chrome. That breadth makes Sider a fit for users who want assistance close to the content they are reading or editing, rather than a chat window alone.
Sider is freemium and has a free plan. Published plan names include Sider Basic, Sider Professional, and Sider Ultra, though offerings may vary between the web and App Store. The product is available on web, Windows, macOS, iOS, Android, and as a Chrome extension. Support channels include documentation. Buyers who value multi-model access and in-browser utilities should consider it; those who want a narrower chat experience or rely on support beyond documentation may prefer another option.
