SSMLocal

Local video subtitle generator and bilingual player

Problem

Existing subtitle tools require uploading videos to the cloud, raising privacy concerns and slowing things down; long videos need full transcription before viewing; local players lack smart subtitle support.

Solution

A local transcription engine based on Whisper that generates subtitles while playing, prioritizing the current playback position; supports bilingual display and subtitle export, all on-device.

Users

Learners and researchers who frequently watch local videos (courses, interviews, meeting recordings)

MVP

Import local video; run Whisper locally; generate and display subtitles in real time; export SRT; toggle bilingual translation

Revenue

One-time purchase $9.99 or freemium with subscription for advanced features (speaker diarization, batch processing)

Why now

Open-source models like Whisper are mature, on-device compute is stronger, and privacy awareness is rising; indie developers can quickly package this into an easy tool
