Subly - On‑Device AI Subtitles, Zero Cloud

Hey Indie Hackers! I’m Parth, founder of Subly, and I’m excited to share our launch with you all. After constant frustrations with slow uploads, unpredictable billing, and privacy concerns, I decided to build a fully offline subtitle tool that lives right on your iPhone or iPad.

What Subly Does

• One‑Click Transcription: Drag in your video, click “Transcribe,” and get perfectly time‑coded SRT/VTT in seconds.

• 100% On‑Device AI: No cloud, no hidden fees, no data leaks—your footage never leaves your machine.

• Style Presets & Animations: Pick from Apple‑inspired overlays, kinetic typography, or create your own branding presets.

• On‑Tap Offline Translation: Instantly translate your subtitles into 30+ languages with a single tap—fully on‑device, no internet required.

Why I Built It

I was sick of waiting on uploads and worrying about client confidentiality every time I captioned a video. I wanted something as fast as local Whisper.cpp, but wrapped in an intuitive UI—so Subly was born.

I’d Love Your Feedback

• Does on‑device AI subtitle generation solve your pain points?
