What it really isSider.ai — AI browser sidebar giving access to 20+ models for chat, research, summarization, and writing.
Our takeSider is a freemium browser extension that embeds a multi-model AI panel directly into your browser, letting you query GPT-4o, Claude, Gemini, Llama, and 20+ other models side-by-side without switching tabs.
The product has a permanent free tier (30 basic credits/day) and paid plans starting from ~$4.20/month on annual billing, which makes it freemium. Standout capabilities include Group AI Chat (compare model responses simultaneously), a deep-research agent with citations, YouTube/PDF summarization, and a personal knowledge base called Wisebase.
Why we rate itSider delivers remarkable value by consolidating 20+ frontier models into a single $4–17/mo browser extension — far cheaper than maintaining individual subscriptions to ChatGPT Plus, Claude Pro, and Gemini Advanced separately.
The catchCredit allocations don't roll over monthly, 'Unlimited' plans still carry caps on advanced models, research exports are HTML-only, and paid-tier support response times draw consistent criticism.

Best / not good for

Best for
  • Researchers and students who need deep, cited web research without tab-switching
  • Power users wanting side-by-side comparison of multiple AI models per query
  • Budget-conscious professionals seeking GPT-4o + Claude + Gemini access under $17/mo
Not good for
  • Users needing offline or native-app AI outside the browser
  • Teams requiring collaborative workspaces or conversation organization (no folders)
  • Heavy API-level automations or workflow integrations beyond browser context
Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast: install browser extension, sign up, and start chatting with AI models within minutes.
  2. Scale breakpoint
    Credit caps become a friction point for heavy daily users on lower plans; 'Unlimited' tiers still impose monthly maximums on advanced models.
  3. Walled garden
    Moderate: knowledge base (Wisebase) and research reports are stored in-platform; exports limited to HTML, complicating data portability.
Still a fit?
If none of these block you, start on the free plan.
