Drop a court filing PDF in and FileCheck tells you whether your redactions are real. It finds text still hiding under black boxes or annotations (the copy-pasteable kind), flags SSNs, dates of birth, account numbers and possible minors' names, checks metadata, and produces a page-numbered checklist PDF with the file's SHA-256. Everything runs in your browser; nothing is uploaded. Free redaction check, $79 once for the full audit. A review aid, not legal advice.
Maker here. A federal study found hundreds of failed redactions on PACER, mostly Social Security numbers hidden under a black box that anyone could copy out. Clerks don't check and the e-filing system doesn't scan, so the filer carries all the risk. FileCheck renders each page and samples the pixels under every text run to catch the cosmetic ones, then runs the Rule 5.2 pattern checks. It never says "clean"; it lists what it found, what it couldn't verify, and which pages are scans. Happy to answer questions, and if it misses something on your filing, tell me and I'll fix it.
