Upload your audio. AI transcribes every word with timestamps and hands you a standard SRT subtitle file — plus a finished video with the same captions burned in. Free, no credit card.
Most "free" SRT generators cap you at 5–10 free minutes, then ask for a subscription. ZinAIStudio has no minute caps — upload your audio (up to 50MB per file), download the full SRT. And because the SRT is produced by our video pipeline, you also get a finished, subtitled HD video with it. Two deliverables, zero cost.
