How to choose
Prioritize agents whose output format matches your target (JSON-LD, PDF, structured prompts). Check if the free tier limits volume or export options. Avoid near-matches that only summarize rather than truly reformat content. Test local vs cloud processing for privacy-sensitive conversions. Start with schema or prompt tools if you need machine-readable output.
