After Algorithm
How it works
Drop a file or paste text. AfterAlgorithm inspects what it can verify, explains what it observes and lets you decide what happens next without turning uncertainty into certainty.
Local inspection
Content is examined in your browser. The inspector does not send the file to the AfterAlgorithm server.
Understand the result
Each observation is paired with meaning, evidence level and limits.
Decide
Download a readable report, save the analysis locally or create a cleaned copy when that operation is genuinely supported.
Filigrane Lab
Watermark Lab: an explicit test, separate from general inspection
Filigrane Lab is a voluntary workflow separate from the inspector: it accepts multiple files, offers Auto, Assisted and Custom creation modes, can estimate a watermark mask, attempt adaptive local reconstruction and export the result in several formats.
Multi-file · Auto / Assisted / Custom · estimated automatic removal · multiple exports · local processing
Test a watermarkInspection is not cleaning
Inspection never modifies content silently. When a cleaned copy is available, AfterAlgorithm states what changed and keeps the original untouched.
What is saved
The report, observations, fingerprint and performed actions can be stored locally. Keeping the original remains optional.
Cleaned does not mean guaranteed safe
Reducing metadata or attack surface is not a replacement for antivirus or dedicated security validation.
