AI-led digital accessibility for documents, images, video and websites
Automated remediation for PDFs, Word files and scanned pages, including complex tables, with CMS and LMS integrations and a Canvas LTI app.
Generates consistent, high-quality image descriptions across mathematics, science, engineering and other specialist subjects at publishing scale.
Closed captions, transcripts and extended audio descriptions for video and audio content, produced with automated plus human review workflows.
ContinuA11Y plugin, colour contrast checker and an audit API for hosted PDFs to find and fix website barriers.
Enterprise developer platform and API for deploying GPT-6 Astra, Sol, Luna, and realtime multimodal agents.
Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
Provides direct API access to Google's Gemini models with generous free prototyping tiers, but lacks OpenAI's ecosystem breadth.
