Was it copied, and was it written by a machine? Measured, with the evidence shown.
Text uniqueness checkFinds the pages that already carry this wording, and what share of your text they cover. Every match is a page we downloaded and compared, not a search result we trusted. AI text detectorScores every sentence against a language model — how predictable each word was, and how far the writing steps off the model's expectations. Probabilistic, and honest about it. Image uniqueness checkFingerprints the picture (pHash/dHash) and looks for the same or a near-identical one already published, including stock-library traces. De-AI text rewriterRewrites a draft so it stops reading as machine-written: stock transitions cut, rhythm varied, over-used words replaced — then measured again with the same detector to prove it worked. De-AI image recoderRe-codes a generated picture so its pixels behave like a photograph — crop, resample, sensor-matched grain, camera-like encoding — and hands the file back. AI image detectorReads provenance metadata (C2PA, generator tags, camera EXIF) and, when that has been stripped, the sensor-level forensics of the pixels themselves.
How the plans divide these up.
Opening a tool is not what costs us anything — volume is. Every tool that runs in your browser is free to everyone, forever, with no counter. What the plan decides is how much one run may cover, how many server-side runs you get a day, and whether results are kept, exported, scheduled or reachable from the API.
- We do not run other people’s code. One tool on comparable lists is an online PHP editor that executes what you paste; Astrina formats PHP and reports syntax errors, and nothing is ever executed.
- Tools that fetch a page identify themselves honestly and obey robots.txt.
- Anything processed in your browser stays there — files are never sent to us.
