Modern Course Downloader
How to find your token
Not just a downloader. A complete, locally-hosted desktop environment for managing your digital education.
Download entire courses or individual lectures with multi-resolution selector (1080p, 720p, 480p), custom speed throttling, and automated subtitle preservation.
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.
Pin massive libraries to an external SSD or network drive. Udeler handles drive unmounts safely and marks courses offline without breaking local indices.
Search through entire course libraries, localized subtitle files (.vtt), and transcript logs to immediately jump to the exact timestamp a topic is discussed.
Your course videos, credentials, and local indices are locked down directly on your disk using hardware-backed cryptography.
Downloaded lectures are encrypted chunk-by-chunk on disk. Decryption occurs exclusively in-memory during playback via custom local protocol handlers.
Renderer bridges undergo rigorous IPC validation with strict call-frequency thresholds to block memory leaks and tampering.
Session keys are tied to Windows Credential Manager, macOS Keychain, or Linux libsecret — never stored in plaintext JSON.
Engineered for international students with instant hot-switching, deep schema inheritance, and community Crowdin sync.
JSON language packs are discovered dynamically on build with deep fallback merging against the master English schema.
Seamlessly updates HTML direction attributes and switches the entire layout dynamically between Latin and Right-to-Left writing systems.
Switch languages on the fly from the login view or settings tab without restarting the desktop client.
