Pros
  • One-time $20 price instead of a subscription
  • Native macOS app, fast and unobtrusive
  • Choice of OpenAI or Anthropic backends
  • Auto-names and tags screenshots for real searchability
  • Inline chat about a captured region without app-switching
  • Genuinely open source (MIT) and model-agnostic via LiteLLM
  • Produces structured, cited reports rather than freeform prose
  • Co-STORM adds human-in-the-loop collaboration with a mind map
  • Pluggable retrievers including a local VectorRM for private docs
  • Backed by Stanford OVAL with active research publications
Cons
  • macOS only, no Windows/Linux/iOS
  • Requires your own LLM API keys (running costs add up)
  • No public API for automation pipelines
  • Niche utility, not a full asset-management system
  • Hosted demo is gated and can be slow or unavailable
  • Output reads like Wikipedia, not like polished editorial writing
  • Self-hosting requires Python plus your own LLM and search API keys
  • Citations can still drift; outputs need human verification
