AI Document Comparison
A diff shows you every changed character; the AI comparison tells you what the changes amount to — which edits are cosmetic, which shift obligations, what the revised version now says differently. AI usage is metered in AI Credit: signed-in free users get 50 AI Credit per month, guests get 0, and paid plans include more.

Meaning, not just markup
Between contract versions, the interesting question is rarely "what characters changed" — it is "did my obligations change". The AI reads both versions and describes the differences at that level: substance first, wording second.
Use with the literal diff
For legal certainty pair this with the deterministic Compare PDF: AI narrates the meaning, the diff proves the letters. AI can make mistakes — always review important output before relying on it. Never accept a revised contract on the narration alone — read the flagged clauses.
