Offline Subtitle Studio AI

Offline Subtitle Studio AI Overview

Offline Subtitle Studio AI – 100% offline AI subtitles for any video or audio — generate, edit, style, export to SRT/VTT/TXT/ASS, or burn in. Your media never leaves your PC. Offline Subtitle Studio AI turns your videos and audio into clean, editable subtitles using on-device AI speech recognition powered by faster-whisper. Everything runs locally on your PC, so your files stay private.

Drag in a file, generate captions, fine-tune timing and text in an editable cue table, apply ASS style presets, then export to SRT, VTT, TXT, or styled ASS — save a sidecar file that loads automatically in players like VLC, embed a subtitle track, or burn styled subtitles into a new video (your original is never modified). A compact model is bundled for fully offline first use; optional larger models (Base, Small, Medium, Large-v2) download once from Hugging Face, then run offline. CPU by default with optional NVIDIA GPU (CUDA) acceleration. One-time purchase — no subscription, no ads, no account.
