OshiKoi — Browser/Extension/Mobile 3D AI Companion Platform

Published · Researched 2026-09-20

Overview

OshiKoi (oshikoi.io) is a 3D anime AI-companion platform launched November 25, 2025 (per its PRLog launch press release), spanning browser, a Chrome extension ("OshiKoi: AI Mate in Your Browser"), and mobile apps (Android package com.oshikoi.app; iOS app referenced on the official site). Companions ("Mates") are real-time-rendered 3D anime characters with live voice and facial expressions, adaptive vector memory ("remembers everything you've shared together"), and community-shared user-created Mates. The platform supports custom VRM/VRoid avatar import, voice cloning, multiple chat models (GPT, Claude, Gemini, OshiLM per official site), real-time AI motion generation, and Discord integration. The official site showed active development through September 2026 (Calendar & Automation update Sept 1, 2026; CyberPunk outfit update Sept 9, 2026).

Social standing

Where people talk about it: Google Play / AppBrain owner reviews (the richest signal), the Chrome Web Store listing, and the platform's own community Mate library (user-created characters with handles like @user_0jjhjyfd, @Lạc_Lạc, @tyler_20831). No Facebook group, Instagram, Threads, Reddit, or public Discord server surfaced in this pass — the social footprint is app-store/community-library driven.

Consensus verdict: genuinely used and liked for cheap chat and Japanese voice, with a real split — enthusiastic 5-star reviews praising cost and character variety sit alongside 1-star reports of crashes, a candy-billing glitch allegation, and setup confusion. This is a live product with real users and real friction, not a promo ghost.

Key social/press moments:

• Nov 25, 2025 PRLog launch release: "browser-based real-time 3D anime companions, emotional animation, adaptive memory, voice, and Discord integration."
• Official site news (observed Sept 21, 2026): "📅 Calendar & Automation Update – September 1, 2026" (Google Calendar link: Mate can view/add/edit events); "🌃 CyberPunk Update – September 9, 2026" (new CyberPunk outfit for official Mates and Staff).
• Chrome Web Store (observed Sept 21, 2026): version 0.2.2, updated July 27, 2026; "Offers in-app purchases"; offered by oshikoi (Integrated Software Solutions, Wilmington DE). A third-party Socket snapshot reported ~6K users and 4.9/5 from 9 ratings — third-party data, treat as indicative only.
• Android app (APKPure/AppBrain): version 1.0.160, updated July 29, 2026.
• AppBrain owner reviews: Jun 16, 2026 (5★, detailed pricing breakdown); Jun 25, 2026 (5★ "Soo cool"); Jul 20, 2026 (5★ "BEST AI Companion app"); Jul 24, 2026 (1★ persistent crashes); Aug 7, 2026 (1★ candy-billing glitch allegation); Aug 25, 2026 (1★ "no preset characters… uploaded a picture, it didn't register").

Main praise (from AppBrain reviews):

• Cheap chat: "Crystals/Candy are cheap compared to ALL the others, if you stick to the lowest chat model."
• Japanese spoken voice option.
• Character variety + make-your-own ("Lots of interesting characters… you can make your own").

Main complaints / failure modes:

• Persistent crashes (Jul 24, 2026 1★: "App constantly crashes, reinstalled, but the problem was persistent").
• Billing glitch allegation (Aug 7, 2026 1★: "keeps spending 8 candies even though it was supposed to be 4… going on for over a year").
• Setup confusion (Aug 25, 2026 1★: "Has no preset characters. When I uploaded a picture, it didn't register").

Representative quotes: "One of the actual best AI chats out there; I'm thoroughly surprised. It costs money, but Crystals/Candy are cheap compared to ALL the others, if you stick to the lowest chat model, which is what I'm using." (AppBrain review, Lance Typhon, Jun 16, 2026). "Great app for anybody who just wants someone to talk to. Lots of interesting characters to choose from and if you by some chances don't like any of them, you can make your own. Hands down the BEST AI Companion app you can find." (AppBrain review, Chris Jarvis, Jul 20, 2026). "App constantly crashes, reinstalled, but the problem was persistent." (AppBrain review, Jordan Jones, Jul 24, 2026). Honest reporting: no Facebook/Instagram/Threads/Reddit/Discord signal found.

Key specs

Pricing

• Free to start; in-app purchases (Crystals/Candy dual currency). Official current price list UNVERIFIED — no official pricing page found; the figures below are owner-reported (AppBrain review, Jun 16, 2026), not official:
  • ~480 Crystals ≈ $4.50 USD
  • 100 Crystals → 2,100 Candy (conversion)
  • Long chats ~14 Candy each (lowest chat model)
  • Outfits ~200 Crystals
• Chrome Web Store confirms "Offers in-app purchases."

Support reality

• Official support: bug reports via the site ("Submit Bug Reports… you'll have to go through Fuyumi first" — an AI staff character); support site oshikoi.io; email contact@oshikoi.io.
• Community support: in-platform Mate sharing; no public Discord/Reddit found despite launch release mentioning Discord integration (integration feature, not a public server — UNVERIFIED).

Verdict

• OshiKoi is the strongest missed 3D AI companion in this lane: launched Nov 2025, verifiably live and updating in September 2026, real owner reviews on both app stores, a browser extension with thousands of users, and a feature set (voice cloning, VRM import, model choice, vector memory, calendar automation) that outguns most desktop-only rivals.
• The honest caveats: pricing is owner-reported, not official; the review split shows real crash/billing friction; and social proof lives in app stores rather than fandom communities. The honest read: this is the "AI companion as a platform" story — browser + extension + mobile + community marketplace — and the September 2026 calendar-automation update shows it's evolving toward agentic utility, not just chat.
