About this app

SubMorph is a professional, privacy-first AI subtitle translation and video localization studio engineered for cinema enthusiasts, content creators, and translators.

Translate English subtitles into natural, dialogue-driven Bengali with zero timestamp drift, guaranteed block synchronization, and standalone offline execution.

🌟 KEY FEATURES:

• 100% Timing Isolation: Unlike ordinary tools, SubMorph never sends raw timestamps to AI models. Your subtitle timing, cue points, and milliseconds stay strictly preserved in memory with zero risk of drift or overlap.

• Built-in Video Subtitle Extractor: Directly extract embedded subtitle streams from MKV, MP4, and WebM video files without waiting for slow server uploads. The entire extraction runs locally on your device!

• Advanced Multi-Model AI Engine: Compatible with Google Gemini, DeepSeek, Groq, and OpenRouter for natural, culturally fluent Bengali translation tailored to movie dialogues.

• Universal Media Player Compatibility: Export clean, standardized .SRT subtitle files ready for VLC, MX Player, Plex, and smart TVs.

• Privacy First & Standalone: Works 100% locally as a guest utility. No account required. Optional cross-device cloud sync with automated 72-hour ephemeral auto-deletion.
