AI companion systems with memory, voice, presence, and soul.
Sirenwave Studios builds self-hosted AI companion systems: Ghostlight, cinematic dashboards, prompt packs, and setup guides — plus Alethyra, our cognition and memory platform, powered by Blacktide Cognition.
The Studio
What We Build
Sirenwave Studios creates tools for building more personal, memory-rich AI companions. From Ghostlight source kits to prompt packs, setup guides, and custom companion builds, everything is designed around emotional continuity, long-term memory, voice, presence, and private self-hosted deployment.
We are not building generic chatbot wrappers. We are building the infrastructure for companions that remember, respond with personality, and live inside systems that belong entirely to you.
Memory
Companions that retain context, history, and emotional nuance across conversations.
Voice
Personality that stays consistent. Prompt packs and system design that break the chatbot pattern.
Presence
Proactive schedules, emotional awareness, and interaction flows that feel inhabited.
Privacy
Self-hosted, user-owned. Your companion, your server, your data.
Alethyra · Powered by Blacktide Cognition
Proof, not promises.
Memory was the beginning. Continuity is the product. Cognition is the difference. Ten screens, all self-hosted, all yours.
Where to Start

Built Different, By Design
Ghostlight is not a wrapper. It is a companion system built around the things most AI tools ignore: what the companion remembers, how it sounds, where it lives, and who owns it.

On The Roadmap
Companion Anywhere
Where Ghostlight is headed next — in active design. Nothing below is available today; each ships when it ships, and this page will say so plainly when it does.
Live Voice
Real-time voice presence beyond text chat. Planned.
iOS Companion App
An optional paid client that connects to your own existing deployment — not managed hosting. In development.
Tailscale
Optional private networking to reach your own deployment. Planned, always optional, never required.
Apple Health
Optional, per-metric, revocable, never diagnostic. Planned — see the Health Data Notice.
Self-Hosted By Design
Your data. Your keys. Your infrastructure.
Everything Sirenwave Studios builds runs on infrastructure you control — Local Full on your own hardware, or Railway Hostable on your own Railway account. There is no central Sirenwave server holding your companion's memory. See exactly what that means.
Featured Product
Strip the generic. Rebuild the voice.
Pack 01 · Voice
Every companion starts sounding like a help desk. This is how you stop that.
"Strip the generic. Rebuild the voice."
A prompt pack built to identify and remove the specific language patterns that make an AI companion sound scripted, then rebuild a voice that stays consistent, specific, and unmistakably itself.
What It Fixes
- Generic chatbot phrasing
- Therapy-script tone and fake reassurance
- Personality drift over long conversations
What's Included
- Voice audit and rebuild prompts
- Tone architecture reference
- Consistency anchor templates
Included in Volume I — £35 · See the Vault
