What is StreamArc?
StreamArc is a Windows desktop app that connects to your TikTok Live stream and lets you react to viewer activity in real time — animated overlays, text-to-speech messages, smart triggers, and more.
Do I need to pay to get started?
No. StreamArc has a free plan and includes a 7-day full Pro trial when you sign up. No credit card required to start.
How does the neural TTS work?
StreamArc uses the Kitten TTS on-device neural engine. The model downloads once (~80 MB) and runs entirely on your machine — no internet required for TTS after that, and no API costs.
Does StreamArc work with OBS or Streamlabs?
Yes. StreamArc overlays and widgets are browser-source URLs you can drop directly into OBS, Streamlabs, or any streaming software that supports browser sources.
What happens if I cancel my subscription?
You can cancel any time through the StreamArc dashboard. Your account reverts to the free plan at the end of your billing period — no charges after that.
Is my TikTok account data secure?
Yes. StreamArc uses a dedicated, isolated browser session for TikTok authentication, and your session credentials are encrypted at rest on your local machine.
Why is Ultra so much just for light mode?
Light mode is terrible and I want to sway people away from it.
