Turn any text, PDF, image or book into lifelike AI speech
Voices trained on large language models deliver lifelike delivery, while Content Aware voices read the text and adjust tone to fit the material.
Speak in over 90 languages and create a custom multilingual AI voice by uploading or recording your own.
Read PDFs, Word documents, ePub, web pages and images, and scan physical books with the built-in OCR camera scanner.
Turn long readings into AI podcasts, get instant recaps, analyse screenshots and equations, chat with your document and generate practice quizzes.

Production AI for the enterprise, deployed inside your own cloud
Every model and agent is tested before release and monitored afterward, with visibility into each run and decision plus alerts when quality slips.
Rules an agent cannot break, combined with human sign-off before risky actions, configured once and enforced across the platform.
Agents execute multi-step work across your existing tools and produce a record of every action they take, carrying context between runs so they never start from zero.
Describe the problem and get a production model served behind an API, retrained as your data changes — with warehouses, lakes, and streams connected without data leaving your cloud.
