## What is Castly?

Finally — your fanfic, web novels, and uploaded books read like a real audiobook.
Castly assigns a unique AI voice to every character, automatically. No more
robotic single-voice TTS. No more waiting for an audiobook that never gets made.

WHY READERS CHOOSE CASTLY

FULL CAST, AUTOMATICALLY
Castly reads your novel and identifies every speaking character. Each one gets
their own AI voice — distinct tone, gender, age, accent. Dialogue feels alive
the way it does in a real audiobook production.

BRING ANY BOOK
Upload EPUB, TXT, PDF, or paste a chapter URL. Drop in an AO3 work link or a
Royal Road chapter. Castly handles the rest — chapter splitting, character
detection, voice casting.

100+ AI VOICES
Pick the cast yourself or let Castly choose. Warm narrators, snarky teens,
gravelly villains, breathy heroines — every voice sounds natural, not robotic.

BUILT FOR LONG-FORM LISTENING
- Smart resume — picks up exactly where you stopped, even on lock screen
- Sleep timer with fade-out
- Background playback plus AirPods and CarPlay support
- Adjustable speed: 0.5x to 3x
- Per-character voice memory across chapters
- Library, bookshelf, and reading history sync across devices

PERFECT FOR
- Fanfic readers who want their AO3 backlog as podfic
- Web novel readers following Royal Road, ScribbleHub, Wattpad
- Indie authors who want to hear their own book
- Anyone with a stack of EPUBs Audible doesn't carry
- Commuters, dog-walkers, dish-doers — anyone who reads with their ears

CASTLY PRO
Unlimited uploads, premium voice cast, offline downloads, and early access to
new voice models. Try Pro free for 7 days.

WHAT MAKES CASTLY DIFFERENT

Most TTS apps give you one robotic voice for the whole book. Castly gives you
a cast. It's the difference between a school librarian reading aloud and a
fully-produced audiobook. Stories with two speakers feel like a conversation.
Stories with twenty feel like a movie.

We built Castly because we were tired of waiting. Half the stories worth
listening to will never get a professional audiobook — fanfic, indie novels,
serialized web fiction, translated work. Castly is for everyone who already
has the story and just wants to hear it.

Privacy: Your uploads stay yours. Castly processes text on-device wherever
possible and never sells your library data.
