If you're comparing live-captioning and translation vendors for a stream, church service, or event and keep hitting "contact sales" instead of a price, StreamTranslate is built the other way: public pricing, self-serve signup, and a free trial you can start right now.

SyncWords is a well-established name in broadcast captioning and dubbing, with real strengths for TV networks, streaming platforms, and large media enterprises — deep workflow integrations, multi-format delivery, and dubbing on top of captions. But for teams specifically translating a live stream — a church service, a Twitch or YouTube broadcast, a webinar — two things tend to send smaller teams looking elsewhere: pricing isn't published, so every evaluation starts with a sales conversation, and the platform is built around broadcast/media workflows rather than a quick browser-source overlay for streaming software.
StreamTranslate solves the second problem by design: it's a browser-source overlay built specifically for streaming software (OBS, Streamlabs, and similar), so captions appear directly in the video you're already broadcasting. And it solves the first problem by simply publishing prices — you can see exact costs on our pricing page right now, no email or call required.

How we compared: based on SyncWords' publicly listed features and broadcast/media workflow focus as of 2026, and our own product's live-streaming feature set. SyncWords is the stronger fit if you're a broadcast or media enterprise that needs captioning combined with full dubbing workflows and post-production tooling — that's a different scope than what StreamTranslate does. This comparison is specifically about live-streamed video (Twitch, YouTube, church broadcasts, webinars), where the two products solve a similar problem in very different ways.
