Ep165: Siteimprove + Bedrock Agents - Powering Accessibility at Scale

AWS and Siteimprove partnered to solve digital accessibility at massive scale using AI.

Digital accessibility ensures 1.3 billion people with disabilities can use web content effectively.

Deep semantic understanding is needed to verify if content truly matches its descriptions.

Siteimprove processes 75 million webpages across government, healthcare, and education sectors daily.

The challenge required AWS infrastructure beyond just AI models for cost-effective scaling.

Their platform unifies accessibility checks with SEO, analytics, and content performance tools.

Business requirements included enterprise security, multi-region support, and flexible pricing models.

They built three processing patterns: interactive conversations, overnight batch, and high-priority async.

The AI Accelerator framework separates business logic from model adapters for easy expansion.

Intelligent routing sends simple checks to Nova micro, complex ones to Nova Pro.

Production system now processes over 100 million accessibility checks monthly using Bedrock Batch.

Key lessons: cross-region inference reduces latency, prompt optimization crucial, special characters increase hallucination.
