Writing, documents and code
Understand, improve
and verify your work.
One workspace for writing, documents and code. Syft shows you what a piece of work is carrying, from AI signals to metadata, provenance, structure and history, with the evidence behind every finding and the tools to act on it.
Free to start · Writing, documents, code, notebooks and images
One workspace
One item, every lens that applies.
Add a draft, a document, a PDF, an image, a source file or a whole folder. Syft reads it in its own form and reports what it carries, finding by finding, with the evidence and the exact location beside each one.
Writing
AI signals with the passages behind them, writing measurements, structure and history. Then Improve, Humanize and Academic Voice to work on what you read.
Documents & PDFs
Metadata, privacy exposure, provenance, structure and the history the file keeps, with Compare and Clean + Verify.
Code & notebooks
Credentials left in source, paths that name your machine, outputs stored in notebooks, and the metadata a file keeps. A folder arrives as one project, tree intact.
Images
Camera and software metadata, Content Credentials read as evidence, and a clean copy for sharing.
Your files are read where they are. Syft Detect processes the text it needs on Syft's own servers and deletes it once the result is ready. See Security and Privacy for how processing and retention work.
How Syft handles your filesSyft Detect
See where writing reads as AI-generated.
Syft Detect reports a signal band for the whole piece and marks the passages that put it there, each with the pattern behind it. It is built for essay-like and academic prose in English.
- The result
- A signal band for the piece as a whole, with a content breakdown: AI-like, uncertain and human-like portions.
- The evidence
- The passages carrying the signal, marked in place, each with the pattern that produced it.
A detector result is not proof of authorship. Read it beside the passages, and decide for yourself.
AI-writing signal band · High signal
3 of 9 sentences in a sample document carry the signal. Read live by Syft’s engine on this page.

Sediment samples from the leeward channel remain consistent with the five-year baseline. It is important to note that Note that these findings underscore the need for continued monitoring going forward. Furthermore, it It is essential to recognize that a proactive and comprehensive maintenance strategy will be crucial to ensuring long-term structural resilience. The commission should re-tender the joint work before the king tides in November.

Real proposals from Syft's Humanize engine. Nothing changes until you accept.
Improve and verify
Then do something about it.
A finding is the start of the work, not the end of it. Syft proposes specific changes you accept or reject, writes the result to a new copy, and checks that copy against the original.
- Improve
- Clarity edits drawn from Syft's own writing measurements: over-long sentences, heavy signposting, filler. One proposal at a time.
- Humanize
- Formulaic phrasing turned into natural wording, with meaning, numbers, quotations and citations preserved.
- Academic Voice
- A consistency check against a style profile built from samples you chose. Similarity of style, never evidence of authorship.
- Compare
- One version beside another: what changed in the text, the metadata, the privacy exposure and the structure.
- Clean + Verify
- Choose what comes out, written to a new copy. Verify rescans the copy and issues a before-and-after receipt.
Academic Voice
See where a draft drifts from how you write.
Build a profile from work you deliberately choose. Syft measures a new draft against it (sentence length, hedging, formality, first person) and shows each difference beside your own reading.
A profile describes tendencies in writing you supplied. It is not proof of authorship and not an identity check.
