Which one should you pick?
Pick AutoCap if
You’re building around mobile creators. AutoCap is the cheap phone captioner you'd hand to someone who films their own clips on an iPhone and just wants captions, not a workflow. Five bucks a month, no watermark, decent fonts.
Pick Subsai if
You’re building around self-hosters running whisper locally for subtitle generation. Subsai wraps Whisper and its faster variants into a usable subtitle generator with web UI, CLI, and Python package — the cleanest single project for running captioning locally without depending on cloud services. Active community, MIT-style license.
