Stream Overlay Generator for Twitch, YouTube & Kick
Your creative brief. One reviewed stream identity.
Approve a style sheet for your logo, face, or mascot, then use it to guide Starting Soon, BRB, Just Chatting, Offline, and Ending scenes plus channel assets. Review the generated pieces before exporting them for OBS.
Animated stream scenes
Starting Soon, BRB, Just Chatting, and Ending can be animated as WebM; Offline is supplied as a static PNG. Preview each result before adding it to OBS.
20 Twitch profile panels
300×100 PNG tiles for About, Schedule, Donate, Discord, Socials — drop straight into your Twitch profile dashboard.
Lower-third label pack
Four 720×120 PNG labels for chat, mic, sponsor, and now-playing strips — sized for the standard lower-third zone.
Transparent cam frame
BiRefNet v2 cuts your cam frame to transparent PNG. Sits over webcam capture without a mask layer.
Brand kit on every asset
Use one approved visual direction across scenes, panels, labels, and the cam frame, then review each generated asset.
Custom scenes from a prompt
Need a scene the library doesn't ship? Type the prompt — GPT-Image-2 paints it, Kling animates it.

Frequently asked
Overlay packs, answered.
- What is an Animated Overlay Pack?
- An Animated Overlay Pack uses one Style Sheet to guide its scenes and channel assets. You can buy a one-time Stream Identity pack on the Pricing page and create its new Style Sheet after checkout, or continue from a Style Sheet already saved in the builder. Review each generative output before exporting it.
- What format do the overlay scenes export to?
- Animated scenes export as transparent WebM with VP9 alpha for an OBS Media Source. Panels export as 300×100 PNGs and lower-third labels as 720×120. Cam frames are transparent PNGs for an OBS Image Source.
- Which AI models generate the overlays?
- GPT Image 2 generates each scene image, Kling Video v3 Pro animates the scenes you select into transparent WebM of up to 15 seconds, and BiRefNet v2 cuts the cam frame's transparent background. Audio is intentionally off, because overlays are meant to run silent.
- Can my AI agent create overlay packs for me?
- Yes, on Pro plans and above. Claude, ChatGPT, Hermes Agent, and OpenClaw can start AlertForge's secure OAuth setup for you — you only sign in and approve access. The agent then plans the pack, shows the exact credit cost before anything is created, and opens the result in the editor. Older clients can use a revocable key as a fallback. See /ai-agents.
