SubSmith Pro

SubSmith Pro is the complete subtitle timing tool for game developers — unlimited cues, every exporter, engine players included.

Everything in the free demo, unlocked: unlimited cues and all exporters — ASS, JSON, Godot 4 GDScript subtitle player, and Unity C# subtitle player.

Time dialogue on the visual timeline, check reading speed against broadcast conventions with the CPS engine (auto-split, duration rules, chars/line limits), preview with karaoke and typewriter effects, manage speakers, and export SRT, WebVTT, ASS, JSON, or drop-in Godot 4 and Unity subtitle players.

One-time purchase of $9.99 USD — yours forever. 100% offline, single portable tool; your dialogue never leaves your machine.

Try before you buy: the free SubSmith demo (https://theluckyduck666.itch.io/subsmith) includes the timeline editor with demo limits (10 cues max; SRT/WebVTT export only).
