In their own words
Aegisub
Aegisub is a free, open-source tool for creating and modifying subtitles on Linux, macOS, and Windows. Its audio interface includes waveform and spectrum views for timing subtitles, while video mode previews edits as they are made. Visual controls on the video frame let users position, rotate, scale, and clip subtitles. Aegisub imports and exports several subtitle formats, including MPEG-4 Timed Text and MicroDVD, and it supports subtitle translation. Editing aids include a translation assistant, spell checking, a thesaurus, syntax highlighting, and macros. The Automation module runs Lua scripts for macros and export filters. Multi-level undo and redo, autosaving, backups, and emergency recovery saving are included. Direct saving to SRT is blocked when override tags would lose information, though the Export dialog can export to SRT. Aegisub does not create DVD subtitles directly; its FAQ describes using an external program to convert SSA to VOBSubs. The optional update checker sends anonymous operating-environment details, including an IP address, and can be left disabled. Version 3.5.0 is listed for download.
Editsub
EditSub is a web-based subtitle editor and management tool for changing subtitle text, adjusting timing, translating subtitles and converting formats. It works with SRT, VTT, SBV, SUB, ASS and SSA files, and exports SRT and VTT. Its AI translation supports more than 100 languages. Local audio or video files up to 10 minutes can be transcribed free without logging in; longer files and translation require credits. The AI co-pilot can flag reading-speed, timing, overlap, gap, line-length and transcription issues, and can fix or rewrite cues. Timing tools include frame-accurate adjustment, batch shifting, waveform synchronization and real-time preview. Video-to-subtitle accepts listed audio and video formats, with a maximum media size of 3072 MB; subtitle uploads are limited to 10 MB. The free plan includes 10 subtitle files. Pro is listed at $4 a year, billed $48 per year, with 1,500 credits per month.
