Editing a PDF takes minutes. Hiding the edit is much harder — the earlier versions are often still saved inside the file. Indagar recovers every one of them, lines them up, and puts the whole file through eight forensic layers. What changed, when, and what doesn't add up.
The evidence is already in the file. A forged document rarely fails one check — it fails several at once, from the raw byte structure of the PDF to the arithmetic on the page. Every file goes through all eight layers, and every result is reported — passed, failed, or skipped because something couldn't be read cleanly. Observable facts you can point to on the document itself. Never a model's opinion. Never a guess.
A PDF that has been edited and re-saved usually still contains the version before the edit — and the one before that. Indagar reconstructs the file's entire save history from its internal update chain and lays every state side by side, so you can watch a name, an employer or a net pay change from one save to the next.
The classic template job: one genuine payslip, re-saved again and again with a different applicant's details each time. Indagar counts the payees, employers and ABNs across every recovered save. A legitimate payslip carries one of each — a reused template can carry dozens. Decisive on its own.
One ABN attached to two different employers inside the same file. There is no innocent version of that, so this layer alone is enough to fail a document.
Every ABN in the file is validated against the ATO's 11-digit checksum algorithm. An invented or altered digit almost never survives it.
The optional live check against the Australian Business Register: does the ABN exist, is it active or cancelled, is it registered to the employer named on the page — and was it registered suspiciously close to the claimed pay date.
Every figure that can be recomputed, is. Net pay must equal gross minus tax. Super must sit at the guarantee rate legislated for the pay date. Year-to-date totals may only ever move forward, and a bank statement's transactions must land exactly on its closing balance. Rates notices and tax returns carry their own arithmetic. A number typed over an original rarely survives a recount.
A census of every embedded font, and a geometric rebuild of every line of text. A figure retyped in a lookalike font, a font used for just a handful of characters, a digit sitting fractionally off its baseline — the fingerprints an edit leaves behind, located and boxed on the page.
Genuine payroll software leaves a signature in the file — and so does a PDF editor. A payslip that claims Xero but was last saved by an editing tool, or producer software that changed between saves, is recorded plainly.
Written to be handed on — to a credit team, an auditor, or a dispute. Every layer listed with its result: passed, failed or skipped. A risk score with its reasons stated in full, save-by-save comparison tables, exhibit pages with the changed content boxed on the document image, and the file's SHA-256 fingerprint, so there is never an argument about which document was examined.
Nothing to install, no templates to set up, no training run. Indagar works on the PDFs you already receive — payslips, bank statements, rates notices, income statements and tax returns.
Drag a client PDF into the browser. Analysis starts on the spot and takes seconds — not a queue, not an overnight batch.
Eight forensic layers run in seconds: every saved version recovered and read, identities and ABNs compared, every figure recomputed, the typography and producer software examined.
A risk score with every reason laid out in plain English, and a report you can attach to the file. Indagar tells you what it found — never what to conclude. The decision stays yours.
The entire analysis happens on your own device. The document is never uploaded, never stored and never seen by us — there is no server copy to leak, because there is no server copy. Two optional checks send only the bare minimum when you switch them on: AI field-reading sends a rendered image of page one, and the ABN lookup sends the eleven digits of the ABN. Nothing else ever leaves the machine.
