Multi-modal internal knowledge and improved internal search

## New Features

### Multi-modal internal knowledge

Now you can add documents not only as PDFs, but also as website links, or transcriptions from YouTube videos (automatically transcribed).\
\
Think of letting AI use all your credible web sources, PDF presentations, and Youtube video tutorials at once.

### Improved internal search

Now [internal search](https://docs.drafter.ai/building-blocks/actions/internal-search) block finds out the necessary information for AI in a much more relevant way.

No more bland or inaccurate results.

### Preview sources before uploading

Ensure that you're extracting and indexing knowledge from the source you need before launching it.

Save your time and credits.\
