TaglineVS Code fork that made AI coding actually work.Wire Cursor's full coding-agent runtime into your own apps, scripts, and CI/CD pipelines with a few lines of TypeScript.The pro's AI video tool. Gen-4 is the current bar.AI-powered networked notes. Roam with a brain.

PricingFree + $20/mo Pro + $40/mo BusinessToken-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.Free + $15-$95/mo$10/mo
Best forDevelopers. Non-developers who want to ship working code.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.Marketing video, pitch decks, b-roll, creative shorts.Knowledge workers + thinkers who want AI in their second brain.
Strengths
  • Tab completion feels like mind-reading
  • Composer for multi-file edits
  • Runs Claude, GPT, Gemini — you pick
  • 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
  • Most mature video workflow
  • Character consistency via Act-One
  • Gen-4 quality is production-grade
  • AI auto-links related notes
  • Generates backlinks + summaries
  • Clean, minimal UX
Weaknesses
  • Can feel overwhelming for non-coders
  • Expensive at scale
  • 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
  • Expensive at scale
  • Still needs post-editing
  • Expensive for just notes
  • Smaller community than Obsidian
Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.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. Market leader with reason. Start here for serious video.A-tier. Niche but beloved. If you've outgrown Notion, try this.
