Yes — MOBI is fully supported on this page, and it is one of 24 formats ReadLoudly reads aloud: documents (PDF, DOCX, ODT, RTF), ebooks (EPUB, MOBI, AZW, FB2, CHM, LRF, LIT, PDB, RB), text and web files (TXT, HTML), comics (CBR, CBZ), and images (via OCR) (JPG, PNG, GIF, BMP, WEBP, TIFF, SVG). Upload an MOBI file here and it opens straight away; any other format on that list has its own reader page.

Yes. This reader runs in the mobile browser on iOS and Android — nothing to install — so you can open an MOBI file straight from your phone's Files app, an email attachment or a cloud drive. Playback continues in the background, and your position syncs to any other device you sign in on.

It is parsed to extract its text, then removed from the processing servers. ReadLoudly does not train models on your files, does not share them with third parties, and does not make them visible to anyone else. Signed-in users can choose to keep an MOBI file in their own private library; a guest upload is discarded when the session ends.

MOBI is Amazon's older Kindle ebook format, still used by many sideloaded books. ReadLoudly opens it directly in the browser, so you do not need the original software that created it.

Every format gets its own reader page rather than being funnelled into one generic uploader, so nothing loses its format-specific handling. Nearest neighbours to MOBI among ReadLoudly's ebooks: AZW, FB2, CHM, LRF. The Tools page lists all of them.
