PricingFree for individuals + $15-$29/user/mo teamsToken-based; requires Cursor plan (Pro from $20/mo). Composer 2 at $0.50/$2.50 per M tokens (in/out); fast variant $1.50/$7.50 per M tokens.FreeFree + $20/mo Advanced (bundled with 2TB Drive)
Best forSolo operators, freelancers, small teams on a budget.Engineering teams who already use Cursor and want to embed its coding-agent runtime into CI/CD pipelines, backend services, or internal developer tools without building agent infrastructure from scratch.Students, researchers, anyone with a stack of PDFs or a topic to learn.Anyone already on Google, research tasks, summarizing long documents.
Strengths
  • Unlimited free tier for solo use
  • Strong summaries + action items
  • Works in Zoom, Meet, Teams
  • Same runtime as the Cursor IDE — no reinventing sandboxing, context management, or model routing
  • Three execution modes: local machine, Cursor cloud VMs (isolated per-agent), or self-hosted workers for air-gapped teams
  • Cloud agents are durable — keep running even if your laptop sleeps or connection drops, and can open PRs automatically on finish
  • Full harness included: codebase indexing, MCP servers, skills, hooks, and multi-agent delegation via subagents
  • Visible in Cursor's Agents Window — programmatic runs can be inspected or taken over manually in the IDE
  • Upload anything, ask questions, get cited answers
  • Audio Overview turns docs into a 10-min podcast
  • Great for studying
  • Native Google Workspace integration
  • Very long context (1M+)
  • Deep Research feature
  • Free tier is generous
Weaknesses
  • Bot-joining model
  • Team features gated
  • TypeScript-only SDK — no official Python or other language bindings at launch
  • Public beta status means API surface and pricing can shift without much notice (Cursor has a track record of surprise pricing changes)
  • Cloud VM costs layer on top of subscription credits, making cost estimation non-trivial at scale
  • Google-only
  • Can be slow on large corpora
  • Writing quality trails Claude
  • Over-refusals on edge content
  • UI is cluttered
Kai's verdictS-tier for solo + free. The best free option, hands down.If your team is already in the Cursor ecosystem, this is a genuinely compelling way to turn ad-hoc AI coding sessions into durable, automated workflows — but the beta label and Cursor's history with opaque pricing mean you'll want to set hard budget guardrails before going to production. (Verdict pending Phi's full review.)S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
