Aoidos turns your documents into natural speech — entirely on your phone.
FREE FOREVER
Aoidos is free. No subscription, no account, no watermark. Built by fntAInhead as a free companion to Temprio (our paid focus app).
ON-DEVICE BY DESIGN
• Your files stay on the device
• Speech is synthesized locally with Kokoro (open-source, Apache 2.0)
• No cloud upload of document text for TTS
• The voice model downloads once (~320 MB) and is reused offline
LISTEN WHILE YOU GO
• Progressive sections: start listening while later audio prepares
• Background preparation with progress % and time estimates
• Lock-screen controls, Bluetooth / headset media keys
• Adjustable speed and multiple natural voices
WHAT YOU CAN IMPORT
• PDF (text layer)
• DOCX
• Markdown and plain text
• Camera scan + on-device OCR for photos and many scans
NOT SUPPORTED
• EPUB and commercial ebooks (excluded on purpose)
ALSO FROM FNTAINHEAD
