🇹🇼 Instinct AI評測：估值三週破25億美元，隱私爭議隨之而來
最近矽谷最紅的話題不是新模型，而是一支只花四個月就把估值衝上25億美元的AI個人助理——Instinct AI。這家由前Sierra研究員Noah Shinn創辦的新創，靠著「不用學新介面，傳訊息或打電話就能用」的產品概念，在邀請制內測階段就吸引Index Ventures、Benchmark等頂級創投搶著加碼，但同時也因為過度寬鬆的權限要求與隱私條款惹出爭議。
Instinct AI是什麼？
Instinct AI是一個能連接你的信箱、簡訊、通話、螢幕與定位的個人代理，你只要傳簡訊或打電話給它，它就會像真人助理一樣訂餐廳、殺價、填表單、訂機票，完成後還會主動回報，不必你三催四請。
操作方式：沒有新介面
創辦人Noah Shinn在X上強調Instinct「沒有新介面」——你不用下載App學操作，只要像傳訊息給朋友一樣傳給它任務，它會自己用手機和電腦完成，行為模式被訓練成貼近真人使用習慣。早期用戶形容，它會訂到餐廳、談好帳單、跟進沒被要求的後續事項。
Instinct AI為什麼估值暴衝到25億美元？
今年稍早Instinct的估值還在1億美元左右，短短幾週內因為口碑爆紅，Index Ventures和Benchmark聯合領投2.5億美元B輪，總募資達3.5億美元，估值直接翻五倍。這種速度就算在AI圈也罕見，反映出創投對「真正能自主完成任務的代理」有多渴望。
Instinct AI有哪些隱私疑慮？
爆紅的同時，質疑聲浪也跟著來。TechCrunch報導指出幾個關鍵問題：
- 權限過度寬鬆：App要求存取信箱、通話、螢幕、定位等大量個資
- 資料保留爭議：即使用戶撤銷授權，部分資料仍會被保留
- 未經確認就寄信：早期測試者反映助理曾在沒有明確同意下寄出郵件
- 條款授權過廣：使用條款給予Instinct永久且不可撤回的資料使用權，可用於訓練AI模型，甚至允許它代表用戶簽署具約束力的協議
值得申請邀請碼嗎？
如果你只是想找個更聰明的行事曆助理，現階段建議先觀望。Instinct目前仍是邀請制免費測試，還沒公布定價模式，功能強大是事實，但把信箱、通話、定位、代簽署權限一次交給一家成立不到一年的公司，風險不小。等條款更透明、資安團隊有更多獨立稽核結果再入手也不遲。
常見問題 FAQ
Q：Instinct AI現在能申請嗎？
A：目前是邀請制內測，需申請或朋友邀請碼才能使用，官方尚未公開定價。
Q：Instinct AI安全嗎？
A：目前有明確的隱私疑慮，包括資料保留、未經同意寄信與過廣的使用條款授權，建議謹慎評估後再授權存取。
Q：Instinct AI跟Siri、Google助理有什麼不同？
A：Instinct主打「無新介面」，直接用簡訊或電話下指令，且會主動跨App完成多步驟任務，而非單純語音查詢。
Q：Instinct AI創辦人是誰？
A：由前Sierra研究員、23歲的Noah Shinn創辦，公司名稱為Spear Street Technology。

🇺🇸 Instinct AI Review: $2.5B Valuation, Privacy Concerns Rise
Instinct AI is the personal assistant startup everyone in Silicon Valley is talking about right now — not because of a new model, but because its valuation hit $2.5 billion in about four months. Founded by 23-year-old former Sierra researcher Noah Shinn, the invite-only agent promises "no new interface": you just text or call it, and it handles the rest. Top VCs are chasing it, but privacy watchdogs are already raising red flags.
What Is Instinct AI?
Instinct AI is a personal agent that connects to your email, texts, calls, screen, and location. Text or call it a task — book a table, negotiate a bill, fill out paperwork — and it acts like a real assistant, following up without being asked twice.
No New Interface, By Design
Founder Noah Shinn has said on X that Instinct deliberately has "no new interface" — no app to learn, just a text thread like you'd send a friend. It's trained to operate a phone and computer the way a human would. Early users describe it booking restaurants, negotiating bills, and completing follow-ups on its own.
Why Did Instinct AI's Valuation Explode to $2.5B?
Earlier this year Instinct was valued around $100 million. Within weeks, word-of-mouth hype drove Index Ventures and Benchmark to co-lead a $250 million Series B, pushing total funding to $350 million and the valuation to $2.5 billion — a 5x jump in a matter of weeks. Even by AI-startup standards, that pace is extreme, and it signals just how hungry investors are for agents that can actually finish tasks autonomously.
What Privacy Concerns Surround Instinct AI?
The hype came with backlash. TechCrunch reported several concrete issues:
- Overly broad permissions: the app requests access to email, calls, screen, and location
- Data retention after revocation: some user data reportedly persists even after access is revoked
- Unconfirmed actions: early testers reported the assistant sending emails without explicit approval
- Sweeping terms of use: Instinct's terms grant a perpetual, irrevocable license to user data — usable for AI training — and even let it enter binding agreements on a user's behalf
Is Instinct AI Worth Requesting an Invite For?
If you just want a smarter calendar assistant, it's worth waiting. Instinct is genuinely powerful, but handing a less-than-one-year-old company access to your inbox, calls, location, and the power to sign agreements on your behalf is a real risk while it's still free, invite-only, and unpriced. Wait for clearer terms and independent security audits before opting in.
FAQ
Q: Can I sign up for Instinct AI right now?
A: It's invite-only beta; you need an invite code, and pricing hasn't been announced yet.
Q: Is Instinct AI safe to use?
A: There are real privacy concerns — data retention after revocation, unconfirmed email sending, and broad data-use terms — so proceed cautiously.
Q: How is Instinct AI different from Siri or Google Assistant?
A: Instinct skips voice-query interactions and instead executes multi-step, cross-app tasks from a simple text or call, more like a human assistant than a voice search.
Q: Who founded Instinct AI?
A: 23-year-old former Sierra researcher Noah Shinn, under the company Spear Street Technology.
