After Algorithm

History and Evolutions (Changelog)

After Algorithm improves clarity, guidance and the local experience without erasing the project history.

V2.4.6

13.09.2026

Version 2.4.6

  • Manual colour sampling fixed: the button now exposes a visible active state, the document shows an instruction directly on the preview and clicking the watermark immediately applies the sampled colour to the mask.
  • The selected colour is shown locally as HEX/RGB with the resulting coverage, and sampling can be explicitly cancelled.
  • Changing colour tolerance now automatically recalculates the mask from the last sampled colour, without requiring another sample click.
  • The mask engine now remembers the last sampled colour so manual adjustment is actually interactive while remaining fully local.
V2.4.5

13.09.2026

Version 2.4.5

  • Definitive fix for the narrow “Creation mode” panel: Auto, Assisted and Custom are now stacked at full width, with no three-column grid that can overflow.
  • Each mode is a complete row with a local SVG icon, title and short explanation; the separate contextual description block was removed to avoid duplication.
  • Automatic actions are also full-width and now use SVG pictograms, with no emoji in the copy.
  • The component is designed around the actual panel width rather than the global viewport, keeping it readable on desktop, tablet and mobile.
V2.4.4

13.09.2026

Version 2.4.4

  • Premium redesign of the “Add or strengthen a watermark” flow: the mention now comes first, followed by a compact and clearer mode selector, without two competing rows of cards.
  • Auto, Assisted and Custom now use visual tabs with local SVG icons, sharper active states and a contextual explanation panel to reduce clutter.
  • The reference link to FiligraneFacile has been moved inside the public-service block, closer to the useful copy, reducing the effect of a large isolated CTA below the module.
  • JS and CSS were adjusted to keep aria-selected in sync, switch contextual mode guidance and provide a cleaner experience on mobile and desktop.
V2.4.3

13.09.2026

Version 2.4.3

  • Filigrane Lab page reorganised: the FiligraneFacile link is now promoted higher inside the reference block, with a shifted CTA that feels less intrusive.
  • The “Add or strengthen a watermark” path is lighter, with more direct copy, visible three-step guidance and clearer Auto, Assisted and Custom cards.
  • The local traceability area now appears after the main settings to reduce clutter at the start, while keeping the local code and After Algorithm identity.
  • Mobile and desktop UI adjustments improve hierarchy, reduce text overload and make the creation flow easier to understand at first glance.
V2.4.2

13.09.2026

Version 2.4.2

  • Major UX fix for mobile and desktop input: silent previews no longer push the user back to the comparison area while typing watermark mention, recipient or date.
  • Auto mode now prepares a dual-colour watermark with a regenerable local After Algorithm code, making origin cues clearer and bringing the experience closer to the official reference flow.
  • New visible settings for primary and secondary watermark colours; the alternating colour pattern is rendered directly in the watermark grid.
  • Added local “After Algorithm” identity inside the watermark plus a local export trace for PNG, JPEG and PDF files generated by the Lab, including code, timestamp and main watermark settings.
  • Multi-result ZIP exports now add an after-algorithm-trace.json file to keep a local batch trace, with no server upload and no claim of cryptographic proof.
V2.4.1

13.09.2026

Version 2.4.1

  • Filigrane Lab UX/UI refinement with clearer action hierarchy, explicit contrast, consistent hover/focus/disabled states and a reset area separated from ordinary controls.
  • Expanded watermark creation with Auto, Assisted and Custom paths; Auto creates a reproducible pseudo-random profile until the user requests another proposal.
  • New straight, diagonal and oscillating layouts, including alternating angles such as +35° / -35°, with controlled density, opacity and offsets.
  • Improved automatic removal attempt: estimated pattern orientation and local adaptive directional interpolation; the output remains an estimated reconstruction, not recovery of original pixels.
  • Exports are presented as direct choices and an explicit link to FiligraneFacile on beta.gouv.fr is added as an independent official reference, without affiliation.
V2.4.0

13.09.2026

Version 2.4.0

  • Filigrane Lab UX rebuilt around two guided paths: test/remove a watermark or add/strengthen a watermark.
  • Multi-file import: add, remove and switch between multiple JPEG, PNG, WebP and raster PDF files, all kept locally with no server upload.
  • Automatic mode now proposes a distributed-watermark mask, shows indicative confidence and can run a local reconstruction attempt; manual mask controls remain available for correction.
  • Visible watermark creator with a mention up to 100 characters, optional recipient and date, colour, opacity, angle and density; apply to the current page, selected document or whole batch.
  • Expanded local exports: re-encoded source format, PNG, WebP, JPEG and PDF, with a local ZIP when raster export contains several results. Reconstruction remains explicitly labelled as an estimate.
V2.3.1

13.09.2026

Version 2.3.1

  • Filigrane Lab hotfix: button states are now explicit, sampling has a visible active state and reconstruction stays disabled until a mask exists.
  • Added an optional second file for the clean reference original, kept locally and used only to compare results.
  • Improved before/after comparison with watermarked source, estimated reconstruction and optional reference original.
  • Reset behaviour clarified: mask reset is separate from starting a completely new test; sticky controls were removed for more reliable interaction and full-page captures.
  • Public documentation synchronized: changelog, llms.txt, ai.txt, PWA manifests and structured data.
V2.3.0

13.09.2026

Version 2.3.0

  • Filigrane Lab added as an explicit workflow separate from general inspection, accessible from the home page, navigation and compatible inspection results.
  • Local robustness testing for JPEG, PNG and WebP with assisted watermark selection, manual masking, estimated reconstruction, comparison and PNG export.
  • Multipage raster PDFs are supported when every page is a full-page JPEG image; vector or mixed PDFs are explicitly rejected so a document is never silently truncated.
  • Lab processing stays in the browser, with no document, mask, document hash or result sent to the analysis API and no CDN or external AI service.
  • Coordinated update of all five languages, methodology, guide, sitemap, llms.txt and ai.txt, PWA manifests and SEO/GEO metadata.
V2.2.13

30.08.2026

Version 2.2.13

  • Mobile menu corrected: the open button no longer overlaps the close button once the menu is displayed.
  • The After Algorithm A symbol is now shown in the mobile-menu header for a clearer brand cue.
  • The contextual MyProID recommendation stays available but becomes a more discreet horizontal strip with no large empty area on the right.
  • The stable 2.2.12 base is preserved: light and dark themes, click-to-open file drop and drag-and-drop remain unchanged.
  • 2.2.13 versioned assets prevent cache mix-ups between 2.2.12 and this UI correction.
V2.2.12

30.08.2026

Version 2.2.12

  • Startup restored to the stable 2.2.10 layer for theme, mobile menu and file drop zone.
  • The 2.2.11 visual improvements are preserved without changing the validated initialization functions.
  • Inspection and sanitizing reuse the proven 2.2.10 engine modules to reduce startup regression risk.
  • Both light and dark themes remain available and the file drop zone keeps click, keyboard and drag-and-drop behavior.
  • 2.2.12 versioned assets and cache rules prevent mixed files across releases.
V2.2.11

30.08.2026

Version 2.2.11

  • The C2PA sanitizing confirmation modal has been removed so the action stays direct and local.
  • A knowledge panel now explains what is removed, why it matters and what remains unchanged.
  • Actions now use clearer verbs: Sanitize and download, Read the report, Export JSON, Download original and Save to local history.
  • After generation, the primary button can download the sanitized copy again without rerunning the purge.
  • MyProID is more visible in result recommendations and the ecosystem using the supplied P mark.
V2.2.10

30.08.2026

Version 2.2.10

  • Image cleaning reinforced: the cleaned copy now removes supported privacy metadata and C2PA payloads from JPEG, PNG and WEBP.
  • The same purge policy is now aligned between single-file mode and ZIP batch preparation.
  • The action area has been redesigned to clearly highlight the cleaned copy action.
  • Local history remains available in a separate, less ambiguous and more discreet block.
  • Buttons now use clearer hierarchy, more distinct colours and inline SVG icons for faster scanning.
V2.2.9

24.08.2026

Version 2.2.9

  • C2PA badge added directly to batch thumbnails when a C2PA structure is detected.
  • No badge is shown when no C2PA structure is detected, keeping the grid easy to scan.
  • A distinct state is reserved for genuinely successful C2PA cryptographic verification.
  • No additional content is sent to the server: the badge only reuses the local inspection result already computed.
  • Changelog and versioned assets move to 2.2.9 without removing 2.2.8 features.

THE FORENSIC PIVOT

From selecting sources to inspecting the material itself

The sudden ubiquity of generative AI shifted the battleground. Transparency was no longer only about how information reached us, but about the nature of the information itself. The tool evolved into a forensic investigation environment. Today, it reveals hidden characters and reads provenance signatures. The machine audits the facts, the human decides.

2025

SEPTEMBER 2025

The origin: Step outside the algorithmic bubble

The domain name was registered on September 18, 2025 with a deliberately contrarian idea. At first, the platform was a self-hosted strategic intelligence tool. The founding promise was simple: collect, sort and prioritize information without being subjected to opaque filters or artificial intelligence imposed by major web platforms.

Step outside the algorithmic bubble.
