Stable Release

Archive your education
without compromises.

The elite, zero-trust desktop client to securely download, decrypt, and manage your purchased Udemy courses. Featuring smart deduplication and external NAS support.

Core Highlights

Engineered for power users.

Not just a downloader. A complete, locally-hosted desktop environment for managing your digital education.

Granular Engine

Batch Lecture & Stream Archiver

Download entire courses or individual lectures with multi-resolution selector (1080p, 720p, 480p), custom speed throttling, and automated subtitle preservation.

SHA-256

Smart Deduplication

If instructors reuse identical files or boilerplate resources across courses, Udeler analyzes SHA-256 hashes and only stores them once to save massive disk space.

NAS Mapped

Storage Volume Pinning

Pin massive libraries to an external SSD or network drive. Udeler handles drive unmounts safely and marks courses offline without breaking local indices.

⌘K / Ctrl+K

Full-Text Transcript Search

Search through entire course libraries, localized subtitle files (.vtt), and transcript logs to immediately jump to the exact timestamp a topic is discussed.

Zero-Trust Architecture

Encrypted Vault Mode

Your course videos, credentials, and local indices are locked down directly on your disk using hardware-backed cryptography.

AES-256-GCM Stream Decryption

Downloaded lectures are encrypted chunk-by-chunk on disk. Decryption occurs exclusively in-memory during playback via custom local protocol handlers.

Zero-Trust IPC Rate Limiter

Renderer bridges undergo rigorous IPC validation with strict call-frequency thresholds to block memory leaks and tampering.

OS Keychain Integration

Session keys are tied to Windows Credential Manager, macOS Keychain, or Linux libsecret — never stored in plaintext JSON.

Audit Status:100% Verified Local IPC
Universal Learning

Universal Localization

Engineered for international students with instant hot-switching, deep schema inheritance, and community Crowdin sync.

Eager-Loaded Translation Schema

JSON language packs are discovered dynamically on build with deep fallback merging against the master English schema.

Bidirectional RTL/LTR Support

Seamlessly updates HTML direction attributes and switches the entire layout dynamically between Latin and Right-to-Left writing systems.

Hot Language Switching

Switch languages on the fly from the login view or settings tab without restarting the desktop client.

FAQ

Questions? Answers.

Is this completely safe to use?

Yes. Udeler Reborn uses a Zero-Trust IPC architecture and Encrypted Vault Mode. Your Udemy credentials and downloaded videos are encrypted on your local disk using your OS-native keychain.

Does it support Udemy Business accounts?

Absolutely. The login portal includes a dedicated toggle for Enterprise/Business accounts to properly route you through your company's SSO.

What happens with DRM-protected courses?

Udeler Reborn automatically detects Widevine/FairPlay DRM encryption on proprietary courses. If an encrypted stream is detected, the engine flags it as "DRM Protected" without crashing or corrupting your downloads queue.

Can I download courses to an external hard drive?

Yes. The app features Smart Storage Tiering. You can pin massive libraries directly to a NAS or external SSD. If you unplug the drive, the app safely marks the courses as offline.

Will it download the subtitles and attachments?

Yes, you have full granular control. You can automatically download all localized subtitles (.vtt) and extra resources (PDFs, ZIPs), or skip them to save space.
