What to build with Kunavo.
- Customer Support
AI customer support
The fastest-ROI AI deployment in any B2C SaaS — automate ticket triage, draft 80% of responses, and escalate the rest cleanly. Production code, real cost numbers, and the compliance pitfalls that catch teams off-guard.
Explore - Knowledge Base
RAG chatbot API
Most internal knowledge bases are dead documentation — nobody finds anything. A Claude-backed RAG chatbot turns them into a real assistant that cites sources and refuses when it doesn't know. Here's the production pattern.
Explore - Trust & Safety
AI content moderation
Modern moderation isn't just regex — it's nuance: sarcasm, dog whistles, brand-context misuse, image+text combinations. LLMs do this far better than rule-based systems, at a price that scales.
Explore - Developer Tools
AI code assistant
Cursor, Aider, Cline, Continue.dev — they're all powered by the same handful of frontier LLMs. If you're building a coding tool (or a co-pilot inside your own dev product), here's the architecture and the cost reality.
Explore - Data Processing
AI data extraction
The boring, valuable use case. Invoices, receipts, contracts, leads, resumes — anywhere you'd previously have built a parser, an LLM with JSON-mode does it in 30 lines, more accurately, and you can ship in a day instead of a quarter.

日本語 RAG チャットボットを Claude で構築 — 5,000 文書のナレッジベースを 30 行で
社内ドキュメント 5,000 件を Claude Sonnet 4.6 で検索可能にする RAG 完全実装。1 クエリ約 0.9 円（prompt caching 適用後）。埋め込みは Kunavo では提供しておらず、その工程のみ OpenAI に直接課金されます。日本語特有のトークン消費・ハルシネーション対策・本番投入チェックリスト含む。
Kunavo 專門為獨立開發者和小團隊的生產級 AI 功能設計。三個真實差異：(1) 文字、影像、影片、音樂統一計費；(2) Stripe 原生結賬，Alipay、Apple Pay、微信支付全部支援，無需走線下發票；(3) 路由完全透明 —— 我們絕不偷換你的模型到更便宜的版本。
多數模型低於廠商官方掛牌價 —— 按模型不同最高低 70%；少數與掛牌價持平，對應的模型頁會寫明。儲值越多額外贈送越多。再加上運營層面的省心：一個帳戶、一份餘額、一套 SDK、無承諾最低消費。每個模型的 per-1M-token 價格在 /pricing 頁直接公示，與上游官方價隨時可對比。
是。我們實現了 /v1/chat/completions、/v1/embeddings、/v1/images/generations、/v1/models、/v1/video/generations 等完整 OpenAI 端點。Streaming、function calling、vision、tool use 全部行為一致。已經在用 OpenAI SDK 的專案改一行 base_url 即可遷移。
永不過期。Kunavo 是按呼叫扣費的預付錢包模式，餘額永久保留，沒有月費、沒有最低消費、沒有有效期限制。賬戶登出時餘額按原支付方式退回。
不會。4xx 和 5xx 響應一律不計費。流式響應在中途斷開時，只扣已生成部分。所有扣費在控制檯「用量明細」按呼叫檢視，支援匯出 CSV 用於對賬。
信用卡（Visa、Mastercard、Amex、JCB、銀聯）、Apple Pay、Link、Cash App Pay、Klarna、Amazon Pay、支付寶與微信支付。本地支付依付款人所在國出現 —— 巴西 Pix、比利時 Bancontact、波蘭 BLIK、奧地利 EPS、葡萄牙 MB WAY —— Stripe 會在結帳頁把美元價格換算成當地貨幣。SEPA、BACS、BECS 銀行代扣不在我們支援的方式內；這些國家發行的銀行卡可正常使用。 自動儲值可按需開啟，需綁定一張銀行卡（支付寶／微信支付無法自動扣款）；綁卡後餘額會按你設定的金額自動補上，$10 起。
Kunavo 執行在單一美東區域（維吉尼亞州 Ashburn），前面是一層就近終止 TLS 的 anycast 邊緣網路。帳戶、帳單與用量資料存放在單一主資料庫中，每日做加密卷快照。
