Most diff tools are built for code, not prose. Essay Diff AI marks deletions red, additions green, and shows the word-count delta as one percentage — then a 'Generate AI Insights' pass summarises the rhetorical change, not just the textual one. Built for students and editors tracking how their writing evolves. Built solo with Claude, shipped to Vercel; next: a version-history view showing a piece's full revision arc.
