Working exclusively in theorem provers other than Lean or Lean4 Looking for general-purpose AI programming assistant beyond Lean's domain ### When should I avoid late-cli? Situations requiring configuration customization to adapt to different project requirements Workflows that need more than 5GB of VRAM for AI model operations and management ### Is LeanCopilot or late-cli more popular on GitHub? LeanCopilot has more GitHub stars (1,314 vs 402). Stars measure visibility, not whether either tool fits your constraints. ### Are LeanCopilot and late-cli open source? Yes - both are open-source projects on GitHub (LeanCopilot: MIT, late-cli: Other). ### Where can I find alternatives to LeanCopilot or late-cli? GraphCanon lists graph-backed alternatives at [LeanCopilot alternatives](/tools/lean-dojo-leancopilot/alternatives) and [late-cli alternatives](/tools/mlhher-late-cli/alternatives) ([LeanCopilot markdown twin](/tools/lean-dojo-leancopilot/alternatives.md), [late-cli markdown twin](/tools/mlhher-late-cli/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/lean-dojo-leancopilot-vs-mlhher-late-cli.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, LeanCopilot or late-cli? LeanCopilot: Very active. late-cli: Very active. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for LeanCopilot and late-cli? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [LeanCopilot trust report](/tools/lean-dojo-leancopilot/trust); [late-cli trust report](/tools/mlhher-late-cli/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=lean-dojo-leancopilot`](/api/graphcanon/graph?tool=lean-dojo-leancopilot) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
