Verify income, identity, and documents before you hand over the keys
Applicants connect bank and payroll accounts through Plaid so earnings are read from the account itself, with no document in the path to forge. Uploaded documents are also analyzed for deposit frequency and real income.
A government ID photographed front and back is matched against a live selfie using facial recognition, catching borrowed identities before keys are handed over.
Uploaded PDFs are read at the byte level for hidden text layers, metadata mismatches, generator fingerprints, and post-generation edits — evidence that visual inspection misses.
Each application returns one of five verdicts (pass, pass with caution, non-recurring, needs review, fail) with a risk level and the specific signals that produced it.

Scans up to 5,000 words at a time and highlights the specific sentences most likely to be flagged as machine-written, so you can see your text the way a detector sees it.
Rewrites AI-flagged passages with different sentence rhythms, vocabulary and tone, keeping your meaning while making the prose read like human writing.
Detectors for AI images, voice recordings, video and deepfakes, plus specialty document tools for checking whether a PDF or screenshot has been manipulated.
Detect and humanize directly inside Gmail, Google Docs or any web page without switching tabs.
