Give TELLTALE some writing you actually wrote. Use emails, texts, posts, essays, or other writing that sounds like you. TELLTALE uses it as a comparison point when you run future scans. It does not prove who wrote anything.

HOW MUCH TO USE. A few hundred words can work. Around 1,200 words gives TELLTALE more to work with. 2,000+ words from different kinds of writing gives it a better picture of your normal style.

Differences in a scan can come from genre, audience, editing, proofreading, professional writing, topic, formatting, dictation, context, or normal variation. This is a writing-pattern comparison, not identity attribution.

What Was Foundevery finding, with receipts
How to read this report. TELLTALE reports observations and evidence found in your text. Some findings are direct technical observations. Some are linguistic or structural signals. Some concern sources and claims. Findings mean more when they appear together. No single weak characteristic is proof of AI assistance. Read this as an evidence record, not a single-number verdict.

How to read a result. Hidden characters found in text are evidence worth checking: zero-width characters can carry invisible watermarks, and non-breaking spaces often leak from AI chat interfaces and formatted documents. Finding nothing proves nothing. Most generated text carries no artifacts, and any text can be cleaned in seconds. Absence of artifacts is not proof of human authorship, and artifacts are not proof of machine authorship: formatted documents and copy-paste from the web leave the same traces. This tool reports what is there. The judgment stays with you.
