About Sider
Sider is a browser-based AI assistant that puts multiple frontier models (GPT-5, Claude 4, Gemini 2.5, Grok 4) behind one interface, with research agents, writing tools, and document analysis layered on top. The pitch is consolidating the AI workflow that's otherwise scattered across separate provider tabs and subscriptions.
The core features that matter
- Multi-model AI chat across GPT-5, Claude 4, Gemini 2.5, and Grok 4 in one place, letting you compare answers and pick the model that handles each query best
- Deep Research automating multi-source research with an AI agent that scans 100+ sources and produces cited reports
- AI Writer for drafting articles, emails, and optimized content with custom tone and style tuning
- Document and multimedia analysis covering PDF, DOCX, PPTX summarization plus insights from videos and images
- Cross-platform availability on iOS, Android, macOS, and Windows with synced chats and files across devices
- AI-powered search enhancement adding model-generated summaries to Google, DuckDuckGo, and other search results
How it stands out
The multi-model aggregator space has Poe, OpenRouter, Msty, and several others. Sider's specific position is the browser-extension format with research and writing tools beyond plain chat. For users who want a single AI workspace that travels with every browser session rather than a separate tab or desktop app, that integration matters.
The honest qualifier: aggregator subscriptions add a layer of cost on top of going direct to providers. Whether Sider's bundle saves money depends on how much you'd actually use each underlying model — if you mostly use one, the aggregator markup isn't worth it. The Deep Research feature is genuinely useful for some workflows but produces variable quality depending on the topic. For users who use multiple AI models heavily across research and writing tasks, Sider consolidates the workflow meaningfully. For users committed to one provider, going direct to that provider's app is often cheaper and more reliable.
