A general-purpose AI agent that executes tasks, not just answers them
Give the agent a goal and it plans the steps, chooses tools, and works through the task in a cloud environment without constant supervision.
Produces finished artifacts such as slide decks, functional websites, small games, and formatted documents rather than raw text.
Runs broad, multi-source investigations and compiles the findings into a structured report.
Generates images, video, and music as part of a larger task or as standalone outputs.

AI voice studio that produces narration, podcasts and audiobooks from a script
Describe what you want in natural language and Noty writes the script, casts voices from the library, directs each line and returns finished audio — asking before it spends your credits.
A searchable library organised by accent, gender, age and best-fit use case, with 18+ voice styles and multilingual star voices that speak every supported language.
On paid plans, record a short sample and read a consent sentence to create a private clone of your own voice that can be cast on any production.
Produce narration, two-host podcasts, audiobooks, songs and instrumentals, narrated .pptx decks, and SRT/VTT dubbing aligned to timecodes.
