Why creators plug AI straight into Castream
Instead of yet another “AI tab” you’ll forget to use, Castream bakes AI directly into the places you already type: title, description, and captions. Enhance what's there, or hand it a wild prompt and let it go to work.
Live Caption Engine
Castream listens to your stream, turns speech into text, and rewrites it in your voice. Use it for live captions now, then reuse that same transcript for clips, shorts, and recaps.
Smart Metadata & Hashtags
Drop in a working title and a rough description. Castream suggests punchier versions, trims to platform limits, and adds hashtags tuned for reach across YouTube, Twitch, and Facebook.
Prompt Studio for Promos
Need countdown copy, recap threads, or email follow-ups? Save reusable prompts for your channel, then generate long-form scripts from the same stream context in a couple of clicks.
Workflow
From idea to “Go Live” in one loop
Whether you're streaming IRL from your phone or pushing RTMP from a full desktop setup, your captions, titles, and prompts stay in sync with how you actually talk on stream.
Draft once
Type your working title and description in Castream, or paste your stream brief / scene list.
Dial in the vibe
Pick a preset vibe (launch, chill, worship, tutorial, raw & unfiltered) or write your own prompt. AI does the heavy lifting while you keep full control.
Publish everywhere
Send captions and metadata into mobile, web, and scheduled streams from the same /desktop command center—no copy-paste circus between tools.
Built for creators, backed by Castream
AI Assistant ships right next to your /desktop experience so you don't have to juggle five tools to get one stream out the door. Pair AI captions and metadata with Castream's multi-platform hub, unified destinations, and scheduled pseudo-live runs.

Under the hood (for the nerds):
Castream combines low-latency transcription with lightweight language models to keep costs sane, then layers your saved prompts and vibes on top. You get smart suggestions and live captions without sacrificing control—or blowing up your bill.
