Captions, Transcripts, Audio Description, and Accessible Media Alternatives

Fact, Inference, and Uncertainty in AI-Assisted Writing
AI-assisted writing can make unlike statements sound equally settled. A documented event, an interpretation, an estimate, a disputed account, and an unsupported completion may all arrive in the same confident grammatical voice. Before polishing or publishing...
Hybrid Retrieval: How Keyword and Vector Search Work Together

How Semantic HTML Shapes the Accessibility Tree
