Studio-grade AI text to speech and voice cloning
Type or paste a script and generate natural narration, with inline emotion and delivery tags such as [whispering], [angry] or [laughing].
Create a usable voice clone from a short audio sample and reuse it across scripts and languages.
Browse and use a large catalog of community voices covering many languages and character styles.
Transcribe audio with multilingual support and emotion or speaker cues for downstream editing.
AI that fills your PDF and Word forms for you
Automatically detects and maps every field in a flat PDF or Word form, using semantic understanding rather than rigid templates.
Each filled field can display its source and the reasoning behind the value, making verification fast and auditable.
Runs concurrent parallel field filling and handles structured row data, so multi-form packets and repeating tables are completed together.
An MCP server lets you fill PDFs from inside Claude Desktop, Code, or ChatGPT, plus n8n and Zapier automations for wider workflows.
