KusArt

Notes compiled from publicly available sources. Last updated: 2026-08-21. Every figure is linked to the source it came from and dated. Verify against primary sources before relying on them.

TL;DR

KusArt is a consumer AI anime-art generator — text-to-image original-character ("OC") creation, style presets, inpainting, upscaling, LoRA training and video generation — operated by KAZAMA INC., a Delaware company at 2810 North Church Street, PMB 747006, Wilmington, DE 19802 (Terms of Service; Last updated April 2026). The product launched under a different brand: it ran as KusaPics on kusa.pics from at least May 2025, and kusa.pics now redirects to kusart.com (Wayback capture, 2025-05-13; redirect observed 2026-08-21) — see Identity and legal entities.

• The company's own archived corporate site states a pre-seed round: "Kamaza.Inc Raises $400K in Pre-Seed Funding Round … with iSeed Ventures as our lead investor", announced 2025-05-12 (archived kazama.inc, captured 2026-02-17). That site is now a dead Vercel deployment (HTTP 404 on 2026-08-21).
• The same archived page is the only source naming the team: "Neko (Caiwei Lu) - Founder & CEO", "LAX (Zhuozhi Li) - Technical Lead", "Roxy (Yuan Zhang) - Growth Lead", plus an R&D and market team with US and Japan backgrounds — see Founder.
• Publicly observable scale is mixed: the style picker on the live site shows per-style usage counters, the largest reading "111.3M uses" for one style (kusart.com; read 2026-08-21), while Similarweb reported only 81.1K visits to kusart.com for July 2026 and a 61% month-on-month drop for kusa.pics (Similarweb, Similarweb) — the brand migration sits between those two pictures, see Notes.
• Money flows through a Hong Kong intermediary: "Sygnal E-commerce Limited is an authorised distributor of our products", at RM 1903, 19/F Lee Garden One, 33 Hysan Avenue, Causeway Bay (Privacy Policy; Effective January 2025).
• Engineering is visible from the served application: a Next.js front end on Cloudflare calling a separate backend at api.kusa.pics under /api/go/ paths, Firebase for auth, a documented B2B API with X-API-Key, credit-freeze accounting and webhooks, and PostHog plus Google Analytics, Reddit and X pixels (page resources inspected 2026-08-21).

Basic

Identity and legal entities

The company writes its own name two ways — "KAZAMA INC." in the legal documents and the domain kazama.inc, but "Kamaza.Inc" in the corporate site's headings, body text and copyright line. No corporate registry filing for either spelling was retrieved — see Notes.

Product

KusArt describes itself as "an AI anime image generator. Powered by exclusive, ultra-aesthetic anime models" (kusart.com; accessed 2026-08-21). The archived corporate site adds that the product is "Built on diffusion models (DMs) and enhanced with proprietary modules" (archived kazama.inc).

Surfaces and feature areas

Commercialization

Pricing pages are not public: the header "Pricing" link points at #pricing, an anchor that does not exist on the page, /pricing returns HTTP 404, and /credits redirects away for logged-out visitors (checked 2026-08-21). The structure below is what the Terms describe.

Reported scale over time

No user count, revenue, subscriber count or generation total is published by the company for either brand.

Content rules as published

The Terms prohibit, among other categories: "Sexual content involving minors, age-ambiguous characters, school uniforms used in a sexual context, or characters presented as underage"; "Non-consensual intimate imagery, sexual exploitation, sexual harassment, or abusive sexual content"; and "Unauthorized use of real persons' likenesses, private images, personal data, or confidential information" (Terms of Service; Last updated April 2026). The company states it operates "internal controls, automated filtering mechanisms, keyword filters, image moderation tools, account risk signals" and conducts "continuous internal monitoring and periodic audits of our AI models and services".

On ownership, the Terms state: "You, whether a legal or physical entity, retain all rights and ownership of your Content. We do not claim ownership of your Content unless you and KusArt specifically agree otherwise in writing", while noting that "KusArt does not guarantee that any generated output is unique, non-infringing, accurate, lawful, commercially usable, or suitable for a particular purpose" and "does not verify ownership of all user-submitted content".

Founder

No team page exists on kusart.com. The only source naming individuals is the company's own corporate site at kazama.inc, archived 2026-02-17 and returning HTTP 404 on 2026-08-21 (archived kazama.inc). It states: "Kamaza is built by an international team with expertise in product thinking, AI capabilities, and cultural understanding".

None of these names appears on the live product site, no headcount is given, and no third-party source reviewed corroborates the roles — see Notes.

Funding

One round is claimed, by the company itself on its now-offline corporate site.

The page states the purpose as: "This Pre-Seed investment will accelerate our AI technology development, expand our product offerings, and strengthen our position in the anime and creative AI community." A search-result summary additionally names Llama Ventures as a participant; that name does not appear in the archived company page and was not confirmed. No investor announcement, filing or press release corroborating the round was found, and no later round is claimed anywhere — see Notes.

Engineering

Technology stack and platforms

No stack page is published. Items below were confirmed from the served application and its network requests on 2026-08-21.

• Front end: Next.js (x-powered-by: Next.js, _next/static assets, App Router locale segments and x-middleware-rewrite: /en), served through Cloudflare (server: cloudflare, cf-ray, Cloudflare Insights); eight locales are declared via hreflang alternates.
• Backend on a separate domain: the app calls api.kusa.pics — observed endpoints include /api/go/categories/list and /api/go/styles/list_for_user; static assets also load from cdn.kusa.pics and a CloudFront distribution (dz2b1yn8y4hm.cloudfront.net). The retained kusa.pics domain therefore still serves the API and CDN after the brand moved to kusart.com.
• Authentication: Firebase — the page fetches firebase.googleapis.com/v1alpha/projects/-/apps/1:751503584748:web:…/webConfig — together with Google Identity Services (accounts.google.com). The B2B API documentation refers to "Firebase web tokens" for ordinary web routes.
• Analytics and marketing: PostHog (us.i.posthog.com, us-assets.i.posthog.com), Google Analytics (G-HC6FZE38L4) and Google Tag Manager, plus Reddit (alb.reddit.com, pixel-config.reddit.com) and X/Twitter (static.ads-twitter.com, analytics.twitter.com) advertising pixels.
• Payments: processed through third parties, with Sygnal E-commerce Limited named as authorised distributor; the Terms reference "payment processors, card networks, financial partners" but name none (Privacy Policy, Terms).
• Models: the product exposes its own named models — Kusa-XL, Kusa-Easy, Kusa-Anima, Kusa-Mix, Kusa-Niji — alongside pages for third-party models (Nano Banana, gpt-image-2, Seedance 2.0). The underlying architecture is described only as "diffusion models (DMs) and enhanced with proprietary modules" (archived kazama.inc).
• No public code: no GitHub organisation or package registry presence under the brand was found (checked 2026-08-21).

Systems

Data handling as documented

The Privacy Policy is short. It says the company collects account information, generated content ("We store content generated by users, such as images created through our AI models"), usage data including IP address, and cookie data; that it does "not sell your personal data"; and that it shares data with service providers and payment processors, to whom it passes "payment amount, currency, and transaction ID" (Privacy Policy; Effective January 2025).

The Terms add that non-subscriber content and prompts may be surfaced publicly by default, that users grant "a non-exclusive, worldwide, royalty-free license to display, host, reproduce, and distribute your shared content within the community areas of our platform and related promotional surfaces" when using sharing features, and that the Services may rely on "AI infrastructure providers" without naming any (Terms of Service). No retention period, subprocessor list, GDPR/CCPA rights section, or statement about whether user content trains the company's models was found in either document — see Notes.

Technical background sought

No careers page, job posting or hiring channel exists on kusart.com (paths probed 2026-08-21). The only role descriptions found are the three team entries on the archived corporate site, which describe work on style recommendation, "unlimited art style models", character consistency and planned "Omni architecture models" (archived kazama.inc).

Industry domain

The work spans diffusion-model image generation and fine-tuning (LoRA training, style presets, character consistency), anime fandom conventions such as Booru tagging, consumer subscription and credit billing through an offshore distributor, multi-locale SEO across eight languages and roughly 160 indexed pages, and content moderation for user-generated character art — including the age-representation rules and likeness restrictions written into the Terms (sitemap, Terms, archived kazama.inc).

Not publicly disclosed

Search scope for the findings below (2026-08-21): kusart.com homepage, /terms, /privacy, /contact, /faq, /blog, /credits, /api-for-business, /train-lora, /nano-banana, /image-generator/*, /events/*, robots.txt, sitemap.xml and the English locale sitemap (159 URLs); probes of /pricing, /about, /company, /legal and /companyprofile; the page's network requests, script hosts and Firebase configuration; WHOIS for kusart.com and kusa.pics; Internet Archive CDX indexes and dated captures for kusart.com, kusa.pics and kazama.inc; api.kusa.pics; the Discord invite API, Instagram, X and YouTube accounts; the Apple App Store; Similarweb for both domains; Crunchbase; and English and Chinese searches on KusArt, KusaPics, KAZAMA INC., Kamaza Inc. and the named team members.

• Pricing. No public price list exists: the header "Pricing" link targets a #pricing anchor that is absent from the page, /pricing returns HTTP 404, and /credits redirects logged-out visitors away. Only the credit/subscription structure is documented, in the Terms.
• Any user, subscriber, revenue or generation total. The company publishes none for either brand; the only quantities on the site are per-style usage counters.
• Corporate registration. No filing was retrieved for "KAZAMA INC." or "Kamaza Inc."; the Delaware address given is a PMB mailbox, not an operating office.
• Which entity collects payment, and through what processor. Sygnal E-commerce Limited is named as "authorised distributor" without explanation of the arrangement, and no payment processor is named in either policy.
• Whether user content is used to train models. Neither the Terms nor the Privacy Policy states a position, and no opt-out is described.
• Data retention, subprocessors and statutory rights. The Privacy Policy states no retention period, names no subprocessor, and contains no GDPR or CCPA rights section.
• The models behind the product. Only marketing names (Kusa-XL, Kusa-Easy, Kusa-Anima, Kusa-Mix, Kusa-Niji) and a generic "diffusion models … enhanced with proprietary modules" description; no base model, provider, hosting region or compute partner is named, including for the third-party models the site exposes.
• Team size and current staffing. The three named roles come from a corporate site that is now offline; the live product site names nobody.
• Funding beyond the claimed pre-seed. No later round is claimed and no investor announcement was found; iSeed Ventures' participation was not confirmed from the investor's side.
• Sources that could not be read on 2026-08-21: kazama.inc (HTTP 404, read via the Internet Archive instead), kusart.com/credits and /manage-subscription (login-gated), and Crunchbase (subscription-gated).

Inconsistencies across sources

• The company spells its own name two ways. The Terms and Privacy Policy say "KAZAMA INC." and the domain is kazama.inc, while the corporate site's headings, body copy and copyright line all read "Kamaza.Inc" (Terms, archived kazama.inc).
• Brand versus documents. The live site is KusArt, but the archived corporate site describes "Our flagship product KusaPics", and the API and CDN still run on kusa.pics — three names in simultaneous use as of 2026-08-21.
• Policy dates predate the brand. The Privacy Policy is "Effective January 2025", before the kusa.pics domain was registered on 2025-03-01 and before the earliest archived capture of the product.
• Scale signals disagree by orders of magnitude. One style's counter reads "111.3M uses" on the live site, while Similarweb reported 81.1K visits to kusart.com for July 2026 (kusart.com, Similarweb). The counters are cumulative and brand-migration traffic still sits partly on kusa.pics, but no source reconciles the two.
• Investors. The company's own page names only iSeed Ventures as lead; a search-result summary adds Llama Ventures, which appears nowhere in the archived page and was not confirmed.
• NSFW positioning. The Terms bar paid features from being used for "Adult content, pornographic services … or sexually explicit paid content" and prohibit sexualised depictions of age-ambiguous characters, while the product's public style categories and marketing lean on "waifu/husbando" character generation; no page states where the moderation line sits in practice.

Other

• A brand migration onto a bought domain. kusart.com was still advertised for sale on PerfectDomain in July 2025, roughly two months after the product launched as KusaPics on kusa.pics; by August 2026 it serves the product and kusa.pics redirects to it, while continuing to host the API and CDN (Wayback, 2025-07-12; observations 2026-08-21).
• The public surface is SEO-heavy. The English sitemap alone lists 159 URLs, of which roughly 30 are single-purpose "Play" generators and a large block are meme-library and style pages, replicated across eight locales (sitemap).
• The corporate site went offline while the product kept shipping. kazama.inc was live as recently as its 2026-02-17 capture and now returns a Vercel "DEPLOYMENT_NOT_FOUND" error, taking with it the only public statements of funding and team (archived kazama.inc; checked 2026-08-21).
• A documented B2B API sits behind a product with no public pricing. The /api-for-business console publishes auth headers, response envelopes, error codes, credit-freeze behaviour and webhook flow, while the consumer plans themselves are not listed anywhere public (B2B API console).
• Contests are a visible acquisition channel: a Seedance 2.0 video contest ran 2026-05-07 to 2026-06-20, and an "Anima AI Creative Contest" advertises "3M credits + $10,000 prize pool" (events/seedance-2, kusart.com).
• Audience is concentrated off-site. Instagram carries 64K followers against a Discord of 637 members and modest measured web traffic, suggesting the brand's reach sits mainly on social platforms rather than on the site itself (figures observed 2026-08-21).
