Kira helps you avoid dead air, react to chat spikes, keep a witty co-host personality on-air, and stay on the agenda you control.
"Chat is heating up! Breathe — let me talk to them."
Kira can jump in with banter, transitions, and reactions when the room goes quiet.
She summarizes what chat is trying to say instead of reading spam line by line.
Agenda, voice, timing, and safety rules are supervised by you.
This block is a controlled landing-page simulation: it does not run real commands or connect to Twitch or YouTube. It previews how Kira could surface chat, agenda, audio, and system logs during a live stream.
Before the gallery, visitors can see the product in motion. The current public walkthrough is available in Spanish while downloads and repository links are still pending.
Watch the current OpenCohost Kira flow: agenda control, co-host reactions, chat context, and the newer interface direction. The hero keeps visitors on-site; YouTube is available from this preview.

The landing page should answer the streamer question first: will this make my show better? Kira is designed for that exact moment-to-moment pressure.
Kira fills the gap with a transition, a question, or a sarcastic aside so viewers do not bounce.
Kira detects the common intent in the flood and turns it into one useful reaction.
Add the topics you want covered and let Kira help you move through them without wandering.
Use selectable TTS options and controlled voice input only when you want Kira to hear the streamer.
Think of Kira like someone in a call watching your chat and reacting with you. She helps host the show, but she does not take over the computer or replace streamer decisions.
Kira does not keep an always-on microphone path running by default because that would make OpenCohost too heavy for many stream setups. If you want Kira to hear you, LiveAudio handles the voice bridge, subtitles, and transcripts, then sends clean context into OpenCohost.
LiveAudio captures your voice path, adds subtitles/transcripts, and keeps the heavy listening work outside Kira by default.
Silero VAD detects when you are actually speaking, instead of treating silence as work.
OpenAI/Whisper-compatible transcription turns voice into text Kira can use as context.
Voice input stays optional so you choose when the co-host can hear you.
These are the product capabilities that matter live: structure, chat awareness, voice presence, avatar states, music control, and streamer guardrails.
Kira follows the stream plan instead of wandering into random topics.
Kira is for creators who need a co-host presence: reactive enough to keep pace with chat, controlled enough to avoid hijacking the stream, and opinionated enough to feel entertaining.
Local mode avoids cloud/API billing, but the real load is handled by your hardware: GPU, VRAM, and games.
| GPU | Game Type | Experience |
|---|---|---|
| RTX 3060 12GBTested | Light / Competitive (Fortnite, Valorant, LoL) | ✅ Lightweight voice mode, responsive and fluid co-hosting. |
| RTX 3060 12GBEstimate | Heavy / Ultra 3D (Cyberpunk, Alan Wake 2) | ⚠️ Lightweight voice mode recommended. Minor delay possible. |
| RTX 4090Estimate | Any game / settings | ✅ Best headroom for heavier local modes; still depends on model, game load, and active features. |
| GTX 1660Estimate | Lightweight games (Fortnite, Valorant) | ✅ Lightweight voice mode; disabling high-poly avatar recommended. |
| No Dedicated GPUEstimate | Just chatting screen / browsing | ❌ Local voice processing needs a dedicated GPU. |
By running the models directly on your machine with OpenCohost and LiveAudio, you free yourself from per-minute voice billing, API limits, and commercial subscriptions. Built and funded by one developer.

OpenCohost Kira is a solo, self-funded personal project, so the hardware lab is literally one PC: an RTX 3060 with 12 GB of VRAM. That single rig is the only "Tested" row here. Every other GPU is an educated estimate, not a benchmark. Real latency and performance depend on your exact GPU, your free VRAM, and your active game load.
Docs are still available, but the landing page keeps the main message focused on streamer value, setup expectations, and honest limits.
Open documentationKira is in active development and testing right now. Running an AI co-host locally, on your own machine, is demanding to get right — so we would rather ship it when it actually holds up live than rush a fragile release. Meanwhile, LiveAudio already ships as proof that the local-first foundation works.
These are the real things we want solid before Kira goes public — not a launch countdown, just the work that earns your trust.
LiveAudio is the local listening layer: a captions and transcription bridge for OBS, and the piece Kira uses to understand spoken context. It runs on your machine, it is released today, and you can use it on your stream right now — no waiting for Kira.
