Talks naturally
It listens continuously, answers when you pause for about a second, and stops mid-sentence if you talk over it.
Live AI co-host
Your AI co-host, live on your PC.
AI Cast Co-host talks with you in real time like a podcast partner, reads your Social Media LIVE chat on air, and remembers every show. It can listen, think and speak on your own computer, or through a subscription or API.
One-time purchase
Can run locally on your GPU
Tested with TikTok LIVE Studio
What it does
A co-host that listens, answers, and reads the room.
Built for people who stream and podcast alone - so you always have somebody to talk to on air.
Reads your Social Media LIVE chat
When you pause - or say "let's check the chat" - it reads comments out by name and reacts. Questions and mentions go first, and it thanks people for gifts and follows.
Can be private by design
Speech-to-text, the language model and the voice can all run on your GPU. Your conversation never leaves your PC unless you choose a subscription or API brain.
Saves every show
Everything you both said, every chat event and which comments it read - with a title and summary written by the model. Search, rename or export to Markdown.
Keeps the show going
If nobody has spoken for a while, it picks the conversation back up. You can turn that off.
Filters the noise
Links, "add me on Telegram" spam, your blocked words, repeated comments and one viewer flooding the chat never make it on air.
Pick its brain
LM Studio or Ollama for free and fully local - or your own Claude or ChatGPT subscription, run isolated with no tools or files.
A whole panel of co-hosts
Add up to five more co-hosts, each with its own name, voice, personality and brain. They talk to each other, and you can sit one out or turn one down with a click.
Rehearse first
Send fake comments, gifts and follows to practice, or replay a recorded chat. "New episode" gives it a clean slate.
How it works
From your voice to its voice, all on your machine.
Replies stream to speech sentence by sentence, so it starts talking before it has finished thinking.
Getting started
Buy once. Your license key arrives by email a moment later.

Pick a brain. LM Studio, Ollama, Claude or Codex - the Test this brain button times a real reply.

Questions
Before you buy
Does it need the internet?
Only for three things: activating your license once, reading Social Media LIVE chat, and - if you pick one - a Claude or ChatGPT subscription brain. The listening, the local model and the voice all run offline.
Once activated, the app checks in quietly when it happens to be online, and keeps working for months if it isn't.
What graphics card do I need?
An NVIDIA GPU with CUDA. With a Claude or ChatGPT subscription as the brain, 6 GB of VRAM is enough. To run the brain locally in LM Studio or Ollama, you need at least 12 GB. Either way, 16 GB of system RAM.
Is it a subscription?
No. You pay once and the license doesn't expire. The first year of updates and support is included, and the version you have keeps working after that. The free local brains cost nothing to run; a Claude or ChatGPT brain uses your own subscription and counts toward its usage limits.
Can I use it on more than one computer?
Yes - a license covers 2 computers. Replacing one? Sign it out from Your licenses on this site and activate the new one.
What happens to my shows and my voice?
Show history is saved on your PC and nowhere else. Audio isn't kept at all - record your stream if you want to keep it. This website never sees any of it.
Mac or Linux?
It's tested on Windows today, and Mac testing is coming soon.
What if it doesn't work on my machine?
All sales are final, so please check the requirements first. If it won't run on hardware that meets them, contact support within 14 days and we'll look at it case by case - see the refund policy.
