Powered by ChatGPT, Gemini, Claude, Grok, Deepseek, etc. Try the best AI sidebar now! Sider AI is a versatile browser extension and app that acts as an AI copilot for research, writing, summarization, translation, and more, integrating models like GPT-5, Claude 4, Gemini 2.5, and Grok 4 right into your workflow on any webpage. It suits students, professionals, content creators, and casual users who want quick AI help without switching tabs, especially those tired of standalone chatbots like ChatGPT. The free tier gives limited daily credits (around 30 basic credits) for core features like chatting with basic models, simple summaries, and translations, plus access to tools like PDF chatting and YouTube summarization with caps. It's solid for light testing or occasional use, but power users often upgrade for unlimited access and advanced models; many reviewers say it's a great low-risk entry point to see if it fits your needs. Plans start free, then Starter at about $4.20/month (1,800 basic credits, 100 advanced), Pro at $20/month (12,000 basic, 400 advanced for full features), and Unlimited at $30/month or $200/year (no limits on credits or models). Annual discounts apply, and there's a 7-day trial for paid tiers; credits cover API costs, so heavy use might need Unlimited to avoid surprises. It integrates top models including GPT-5 and GPT-4o, Claude 4 and 3.5 Sonnet, Gemini 2.5 and 1.5 Pro, Grok 4, Llama 3.1 405B, and even a Sider Fusion model for blended responses. Yes, you can easily switch or use group chats to compare outputs in one go, which users love for getting diverse perspectives without multiple apps. Standouts include Deep Research Agent (scans 100+ sources for visualized reports), Wisebase (AI knowledge base for storing notes and files), sidebar chatting on any page, PDF/image analysis, YouTube summaries, translation in 50+ languages, image generation, and code review. These make it a one-stop tool for brainstorming, grammar checks, and data analysis, saving users up to 8 hours weekly per reviews. Sider uses secure API calls to models without storing your chats unless you opt into Wisebase, and it complies with standard privacy policies, but it does track usage for improvements. Some privacy-focused users on Reddit note concerns over search history logging in the extension, so review their terms; overall, it's considered reliable for non-sensitive work, but avoid uploading confidential files.
