One check. Plagiarism, AI writing, and originality — all in one report.
TXT Audit scans every document against web and academic sources, models it for AI‑generated writing patterns, and rolls it all up into a single similarity score you can trust before you hit publish or submit.
Three checks, run together
Every upload is put through the same three passes, so nothing slips through because you only ran one kind of check.
Plagiarism detection
Fingerprint matching against a broad index of web pages, publications, and academic sources, with the exact passages and sources flagged in your report.
AI content detection
A separate model looks for the statistical fingerprints of AI‑generated text — sentence rhythm, token predictability, and structure — and gives you a likelihood score.
Similarity scoring
Fingerprint and semantic matches are combined into one 0–100 originality score, so you get a single number alongside the detail.
Upload once, read one report
Paste text or upload a file, and TXT Audit highlights exactly what needs a second look, right next to the source text.
Quarterly Research Summary
The findings in this section largely mirror established models of consumer behavior under uncertainty, though the sample size limits how far the conclusions can travel.
Prior studies have shown that adoption curves flatten once network effects reach a critical mass, a pattern this dataset appears to confirm across all three cohorts.
One passage closely matches a published source.
Low‑to‑moderate confidence of AI‑assisted writing in two passages.
