It comes down to fit, not a single winner: Augment Code leans into context Engine with live, codebase-wide understanding, while LegacyDoc AI is built for AI code audit report generation. Augment Code edges the Editor Score (4.4 vs 4.1), but a 0.3-point gap rarely outweighs picking the tool whose features match your work. LegacyDoc AI is the lower-cost place to start thanks to its free or freemium plan; the other is worth a trial if its feature set fits better.
Augment Code has the higher AInexfinder Editor Score (our editorial rating from features, value and pricing, blended with verified user reviews where a tool has them), but "better" depends on your needs — compare features, pricing and the pros & cons above to decide.
Augment Code (subscription) is best for context Engine with live, codebase-wide understanding, while LegacyDoc AI (freemium) is best for AI code audit report generation. See the full feature and pricing comparison above.

LegacyDoc AI is usually the easier starting point thanks to a lower barrier to entry. Beginners should favour a free tier and a simple interface over raw power.
