Key Features

• Text-to-audio generation from text prompts for music sketches, ambient beds, and sound effects.
• Audio-to-audio editing workflows to modify existing files.
• Audio inpaint mode for editing or replacing parts of an existing audio file.
• Runs entirely in the browser; no software installation is required.
• Credit-based usage: new users get 100 free credits; paid packs start at $9.90; credits are used for text-to-audio, audio editing, and inpaint workflows and do not expire.

Who this is for

This product is aimed at creators who want to quickly prototype or sketch musical ideas and sound design in the browser, and at users who need to edit or inpaint existing audio without installing software. The free credits make it possible to test one short generation before buying additional credits. Note practical limits: the service operates only in the browser and free usage is limited to the provided credits. Several operational details are not specified publicly, including per-generation credit costs, supported file formats and size limits, ownership/licensing of outputs, model training data, API or enterprise plans, latency, and support/refund policies.
