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.
Graph, vector and text retrieval for AI agents on your Postgres
Query graph, vector, full-text and hybrid retrieval through one consistent interface instead of stitching multiple systems together.
The open-source pgGraph engine follows relationships across your records, enabling multi-hop and shortest-path retrieval without moving data.
Semantic search over embeddings combines with sparse and full-text matching so queries that mix meaning and exact terms still work.
A dashboard playground, CLI for imports and configuration, and a typed Python SDK make it straightforward to prototype and then ship.
Provides vastly superior ultra-realistic voice quality and cloning, but lacks native document reading workflows.
