The record

Current status: The Doppel repository was renamed to File Foundry, and the release notes say its published identity changed from Doppel to com.junowoz.filefoundry.
What it does: File Foundry is a native Apple Silicon macOS app with local first tools for finding exact duplicates, organizing media, and converting files with FFmpeg.
Duplicate detection: Duplicate Finder verifies exact duplicates byte for byte and moves selected copies to Trash without permanently deleting files.
Media organization: Media Organizer scans selected media folders, plans a dated library, and creates verified copies while preserving originals.
File conversion: Converter handles video, audio, and image files through a local FFmpeg executable with presets, command preview, cancellation, and overwrite refusal.
Privacy: The app has no login, analytics, telemetry, tracking, or external SDKs and accesses only folders and files selected by the user.
Update network access: The updater contacts GitHub Releases only after the user explicitly asks to check for updates.
Platform requirement: Available builds are arm64 only and require macOS 14 or later.
Downloads: The repository lists a drag to Applications DMG installer and an app bundle ZIP for manual installs or in app updates.
FFmpeg requirement: Using Converter requires FFmpeg installed locally, and the page gives brew install ffmpeg as the install command.
No integrations listed: The repository identifies local FFmpeg as a dependency but lists no external product integrations.
Maker: The maker's GitHub profile describes Doppel as an open source, local first exact duplicate finder for Apple Silicon macOS with safe Trash cleanup and no login or telemetry.
Maker location: The maker's GitHub profile lists Brazil.
Purpose: Doppel creates separate ChatGPT desktop app instances with distinct accounts, data directories, names, and icons.
