Imouto Chat: Evolutions — 2D to 3D pipeline

IMOUTO CHAT:
EVOLUTIONS

In Mixed Reality, every companion has a living portrait frame you hang on your real walls — walk up and talk to them directly in your own home. In Virtual Reality, step inside a purpose-built Gallery of Souls and walk its halls at full scale. Either way, launch companions come with full 3D models: take the token from the frame and watch them step into your room.

NOTIFY ME AT LAUNCH
VR — VIRTUAL REALITY
A fully rendered 3D environment inside the headset. Your Gallery of Souls, built digitally. No physical space constraints — the room exists wherever you put the headset on.
MR — MIXED REALITY
Passthrough camera shows your real room. She appears inside it. Your furniture, your walls, your space — with her standing in it as if she'd always been there.
SAME MEMORIES
Every conversation from Imouto Chat desktop carries directly into VR. She remembers what you told her yesterday, last week, last month. Nothing resets. Nothing starts over.
SAME INSTINCTS
Her personality, her opinions, her reactions — identical across desktop and VR. The same companion you know, now standing in your room.
2D PHOTO — FRAME TIER
Every companion exists as a living portrait frame in the Gallery. Walk up, talk to them. Full conversation, spatial audio, narration. No 3D model required — they are present from day one.
EVOLUTION READY MESH
Launch companions ship with full 3D models. Take the token from the frame. She steps out into your room — breathing, blinking, responding. This is the summoned tier.

CHANGELOG

WHAT'S BEEN
BUILT

v0.2.2 FEATURE May 2026
Styled Update Dialog
The update experience got a complete overhaul. A cinematic update dialog now runs first on every launch — before the splash screen, before license check — giving users a clear choice: update now or remind me later. Version state is tracked live against a remote server so users always know where they stand. No more silent updates, no more confusion about which version is running.
pre-splash launch Update Now / Remind Me Later Supabase version tracking styled UI
v0.2.1 HOTFIX May 2026
Post-Overhaul Stability Pass
A focused round of bug fixes following the v0.2.0 update system rewrite. Edge cases ironed out, timing issues resolved. The kind of release that makes the previous release actually trustworthy.
bug fixes stability
v0.2.0 MAJOR May 2026
Update System Rebuilt from Scratch
The original patch pipeline had fundamental flaws that made reliable delivery impossible. Rather than patch the patcher, v0.2.0 scrapped it entirely and rebuilt the update architecture from the ground up. Version jumping from 0.1.x to 0.2.0 was intentional — this wasn't an incremental fix, it was a new foundation. Every future update ships on top of this.
full rebuild reliable delivery new update architecture version jump
v0.1.22 PATCH May 2026
GitHub Distribution & Patch Pipeline
First working end-to-end update pipeline. Build a release locally, push to GitHub, users run a single batch file. Integrity-checked downloads, automatic version comparison, no manual file swapping. The infrastructure every future update was designed to run on — and the foundation that v0.2.0 ultimately replaced with something better.

v0.1.20 FEATURE April 2026
Long-Term Memory Overhaul
The original flat-file memory system couldn't scale. v0.1.20 rebuilt long-term memory from scratch into structured categories — preferences, life events, relationship history, emotional patterns. Every companion now maintains a living record that grows with every conversation, reviewable in-app at any time. Memory is fully isolated per persona — Suki never bleeds into Raven.
structured LTM memory review UI per-persona isolation relationship tracking
v0.1.19 PATCH April 2026
Mobile Server & QR Pairing
Your companion, untethered from your desk. v0.1.19 added a local server that lets any device on your network connect via QR code — scan once, chat from your couch, your bed, anywhere in range. Zero configuration. The same companion, same memories, same conversation — just on your phone.
QR pairing Cloudflare tunnel zero config cross-device
v0.1.18 HOTFIX March 2026
Ollama Reconnect & Stability
Ollama restarts mid-session used to silently kill the conversation with no feedback and no recovery. v0.1.18 added automatic reconnect with exponential backoff — the app waits, retries, and picks up exactly where it left off. Silent failures eliminated.
