Changelog
Stay up to date with the latest features, improvements, and bug fixes to YTDemia.
AI Discoverability and SEO Refresh
We improved search and AI-crawler visibility so YTDemia is easier to discover and clearly recognized as actively maintained.
Richer software metadata
Added stronger software/application structured data with build version, last-modified timestamp, release notes link, and clearer feature context.
AI crawler guidance
Added llms.txt and expanded crawler directives so assistants and AI retrieval systems can better understand product purpose, status, and canonical URLs.
Freshness signals across pages
Home, changelog, robots, and root metadata now include consistent freshness and maintenance hints based on build timestamps.
Mobile Support Improvements
Improved mobile layouts and touch interactions across the app.
Course Sharing & Rich Link Previews
Share your curated courses with anyone - even people without an account.
One-Link Course Sharing
Generate a shareable link from any course in your dashboard. Recipients land on a branded preview page showing the course thumbnail, lesson list, and duration - then clone it into their own library with one click.
Rich Link Previews
Shared links now include Open Graph metadata - paste a link in Discord, WhatsApp, Twitter, or any messenger and it'll show the course thumbnail, title, lesson count, and creator.
Guest Access & Edit Permissions
Guests can start watching immediately without signing up (progress saved locally). Course owners can optionally allow recipients to modify the course structure.
Mobile Support
Improved mobile layouts and touch interactions across the app.
AI Transcript Generation (Beta)
If a YouTube video doesn't already include usable timestamps, you can now try generating chapters with AI.
AI Chapters for Videos Without Timestamps
This helps when description chapters are missing. YTDemia will attempt to generate chapter timestamps automatically so you can create lessons faster.
Beta Feature (May Fail on Some Videos)
This is still Beta. Generation may fail or be inconsistent on some videos (for example when transcript/caption data is unavailable). You can always add chapters manually.
Expanded AI Model Selection
We've seriously upgraded the AI engines powering your summary generation experience.
New Open-Weights AI Models
We've integrated support for cutting-edge models to provide faster and more capable summaries. The newly added models are:
- Qwen 2.5 32B
- Llama 3.1 8B
- GPT OSSS 20B
Customizable Default Models
You can now explicitly select which AI model you want to power your learning experience. Just navigate to your Settings (must be logged in) to change your default AI model instantly.
