AIKO: AI Girlfriend 3D Life (olympus studio)
Published · Researched 2026-09-20
Status: Included. Indie 3D life-sim AI girlfriend — fully animated 3D companion living in a 3D home with needs, routines, memory, voice + lip-sync. Research current as of September 20, 2026.
Overview
AIKO, by developer olympus studio (dev handle Sam), is an 18+ 3D life-simulation AI companion in Early Access. The pitch: a persistent anime-style companion who lives in her own 3D home, follows daily routines, and remembers you. Key features per the developer's official itch.io page (observed Sept 2026):
- Fully animated 3D companion in a dynamic 3D home; multiple save slots / multiple AIKOs
- Persistent memory (claims weeks-long recall: "She actually remembers conversations from weeks ago. It's wild." — this quote is marketing-cited from Reddit, not independently observed)
- Real-time voice input with premium TTS + lip-sync; Whisper speech-to-text
- Needs simulation (hunger, energy, social, fun), 9 emotional states, 21 emotions / 101 facial expressions
- 45 personality traits; body sliders, outfits, hairstyles; 18+ content
- Windows + Android + iOS; Steam release slated for December 2026 (SteamDB shows it prerelease)
- Developer claims a 70B-parameter model (dev claim, UNVERIFIED)
Social standing
The social pulse is thin on Instagram/Facebook but real on app stores and niche communities:
- Instagram/Facebook search (Sept 2026): No meaningful AIKO-specific organic posts found — queries returned unrelated content (e.g., dessert "AIKO" results). No Facebook-group owner consensus or representative quotes available in this pass.
- Google Play traction: 500K+ downloads, 4.37★ from ~6,700 ratings (AppBrain, Sept 2026); one aggregator reports ~650K total downloads with ~71K in the preceding 30 days. The game is young and growing fast.
- Review sentiment (chrome-stats aggregation of Play reviews): Praise for visuals and the romance/life-sim feel; recurring complaints about the AI being slow or unresponsive, commands not followed, movement/standing bugs, a sleeping-eye glitch, and shop navigation bugs. Older reviews wanted more customization (voice, name, appearance) — the dev has since added much of it.
- Communities: a dedicated subreddit (r/AikoAIGirlfriend3D) and Discord exist; developer posts weekly updates and is publicly active.

Pricing (as reported, dated)
From the developer's official itch.io page (olympus-studio.itch.io/aiko-ai-girlfriend, observed Sept 2026):
- Windows: three tiers — $5, $10, and $20 (one-time). The $20 tier runs the LLM locally/offline; lower tiers are server-streamed.
- Mobile (iOS/Android): free tier on the app stores (per dev FAQ).
- No subscription, no microtransactions per the developer's stated model.
⚠️ Tier names/features beyond the price points weren't fully extracted in this pass; in-app purchase pricing on mobile is UNVERIFIED. itch.io pricing is dev-direct and primary-sourced.
Support reality
- Solo/small-team developer, but unusually transparent: weekly updates, public Discord, Reddit presence, and a candid feature list. Better community signal than most indie companion apps.
- Bug complaints (movement, sleeping-eye glitch, AI responsiveness) are the main support load; no data on resolution speed.
Community verdict
The indie dark horse: real 3D life-sim depth, a transparent dev, no subscription, and fast-growing downloads — but polish is the risk (bugs and slow AI are the top complaints), and the 18+ positioning plus weak IG/FB presence mean it lives in a different lane from the mainstream picks. The takeaway: the best "pay once, own the 3D girlfriend" value proposition in the track, with eyes open on Early Access jank.
Primary images
aiko-01.jpg— official itch.io cover art (olympus-studio.itch.io), "AIKO AI Girlfriend" branding over the 3D home. Primary pick.aiko-02.jpg— in-game screenshot (3D home, dancing animation, AP/bond meters) via AppAgg listing.
Both verified JPEG, content-accurate. Note: a first candidate for aiko-01 (a Japanese avatar-customization app screenshot misattributed on an aggregator page) was rejected and replaced with the official cover art.
Evidence status
- Play stats (4.37★, ~6,700 ratings, 500K+ downloads) from AppBrain/aggregators, Sept 2026.
- 70B model claim: developer claim, UNVERIFIED.
- No organic Instagram/Facebook owner posts or representative social quotes found in this pass — social standing rests on store reviews and the dev's community.
