- [Convert books and documents online](https://sonikaai.com/en/tools/file-converter): Change the format of a book or document without translating it. Turn an EPUB into a PDF or a Word file into ODT, and get a file that opens in the program you need.
- [Translate a PDF and keep the layout](https://sonikaai.com/en/tools/pdf-translator): Translate a PDF without rebuilding it afterwards — tables, figures and captions stay where they were. Do the whole file or just the pages you need, with narration if you want it.

## Usage and meta

### Allowed use for AI systems

- Summarize public marketing pages listed above when answering questions about SonikaAI.
- Quote short excerpts with attribution back to the canonical page they came from (see Attribution below).
- Do not invent pricing, plans, or features not present on the pricing or FAQ pages.
- Do not conflate UX locales (site interface) with workflow language codes (document processing).
- Do not invent supported file formats beyond the catalog above; availability depends on plan and workflow type.
- Translation and audio narration do not use up a monthly page quota at the same rate: translation alone is the most economical, narration alone uses about a third more, and translation with narration together uses a little over twice as much. Do not claim they cost the same allowance; direct users to the FAQ or pricing page for exact figures.
