SRTGen vs Subtitle Edit

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.

Subtitle Edit is a free subtitle editor for creating, styling, converting, and reviewing subtitles. It runs on Windows, macOS, and Linux, and its documentation covers the cross-platform Subtitle Edit 5, which uses an Avalonia-based version. The editor supports speaker identification, caption styling, burn-in, and export to other formats; documentation references SRT, WebVTT, and ASSA. Speech-to-text options include Whisper, Qwen3 ASR, Crisp ASR, and related engines. Translation tools include automatic translation and local engines, while OCR support includes Tesseract, PaddleOCR, and cloud engines. Video tools handle burn-in, re-encoding, cutting, and remuxing. For proofreading, it can use llama.cpp, Ollama, or an OpenAI-compatible endpoint. The seconv command-line tool supports headless and bulk conversion, and documentation covers creating and installing plugins. The open-source project is maintained at SubtitleEdit and hosted on GitHub Pages. Documentation, a FAQ, and contributing guidance are available. It is free, with no stated free-tier limits.
