The short version
- Only Read the Docs has a free tier, so it costs nothing to try first.
- Each has a real cost: GitHub Copilot agent mode lacks deep tool orchestration and iterative execution compared to specialized agentic tools; Read the Docs build configuration is finicky, and build failures on dependency changes are a common frustration
- They diverge on capability: GitHub Copilot covers Code completion, Read the Docs covers Build on commit.

- Suggestions for niche or specialized programming languages are less accurate due to limited training data
- Less effective with non-English prompts or grammatically incorrect developer instructions
- Free tier severely limited to 2,000 completions and 50 chat requests per month
Read the Docs
- Build configuration is finicky, and build failures on dependency changes are a common frustration
- Default themes are recognisable and dated, so sites look alike unless customised
- Private documentation requires a paid business plan
- Build times on large projects are slow enough to interrupt a review cycle
