SRTGen vs VisualSubSync

SRTGen is a web and API platform for creating and localizing subtitles for video and audio. It transcribes uploads into editable, time-coded text, then lets users review captions, translate them, style them or burn them into video. Subtitle exports include SRT, VTT, ASS and TXT; JSON is available through agent localization. The service supports 100 caption languages and a workflow combining transcription, translation, voice dubbing, review and export. Its stated content range includes social videos, podcasts, courses, marketing videos and news. The free plan includes 20 signup credits, 20 transcription minutes and 40 translation minutes, with recording capped at five minutes and 720p. Paid plans start at $4 per month for the first two months, then $8 per month. Monthly or yearly billing and non-expiring top-ups are offered. SRTGen also supports MCP-compatible agents, collaborative workspaces and a REST developer API on higher plans.

VisualSubSync is a Windows subtitle editor built around an audio waveform. Users create subtitles by selecting audio regions and entering text, or load plain-text or RTF transcripts for synchronization. It supports SRT and SSA/ASS formats and exports SRT. Checks flag overlapping subtitles, display times that are too short or long, and lines exceeding a configured length; speed indicators and network suggestions support review. Network mode lets others submit missing words or subtitle suggestions through a browser. A translation mode displays a second subtitle file for reference without editing it. Work can begin with a video, followed by WAV audio extraction and waveform editing. Playback uses Windows DirectShow, and some files may need codecs or splitter filters. The project lists version 1.0.1, dated 2013-06-29, and is released under GNU GPL version 2.0. The maker describes it as a hobby project developed in Delphi and C++.
