Can AI-generated art or music be copyrighted?
This is general information, not legal advice, and the answer differs by country. But the shape of it is now clear enough to act on.
The shape of the answer
Output the machine produced on its own is, in most places, nobody's copyright. The US Copyright Office has said so repeatedly, most fully in its 2025 report on copyrightability: material generated entirely by AI is not registrable, and typing a prompt — however long — does not by itself make you the author of what comes out. Courts in the US have agreed on the narrow point that a non-human cannot be an author.
What you contributed is protectable in the ordinary way. Lyrics you wrote, a script, a selection and arrangement of many generated pieces into one work, substantial edits, your own voice or performance, a painted-over render — these are human authorship and are treated as such. In the US you register the work and disclaim the AI-generated portions; other jurisdictions reach similar places by different routes (the UK has a specific computer-generated-works provision that is under review; the EU and Japan look at the human contribution case by case).
Platform terms sit on top. Whether you may use the output commercially, whether the platform keeps a licence to it, whether free-tier output is treated differently — all of that is in the terms of the tool you used, for the plan you were on, on the day you used it. Read the current version; they change.
Why this makes the record you make today matter
Notice what every one of those answers turns on: what did the human do, and when. That is a question of evidence, and evidence is easiest to make at the time and nearly impossible to make later. Six months on, nobody — including you — can reconstruct which forty generations you threw away or which verse you rewrote by hand.
So the practical advice is the same in every jurisdiction: document your contribution the day you finish, and fix the date. That is what the human contribution field in an authorship record is for. It is frozen into the record with the file's fingerprint and your name, anchored to a public chain that night, and verifiable by anyone later. It does not decide whether you hold copyright; it is what you would need to show whoever does decide.
What to write in the contribution field
Specific, modest, true. “Wrote all lyrics. Generated ~40 candidates in Suno, chose one, re-ordered the bridge and the final chorus. Re-recorded the lead vocal myself. Mastered in Logic.” Avoid adjectives; list acts. If the honest entry is “prompted and picked one”, write that — a record that overstates is worse than no record, because it is the first thing the other side will test.

AI 生成的圖和歌，有著作權嗎？
以下是一般資訊，不是法律意見，而且各國答案不同。但輪廓已經清楚到可以據以行動。
答案的輪廓
機器自己產出的部分，在多數地方誰的著作權都不是。美國著作權局講過很多次，最完整的是 2025 年那份可著作性報告：完全由 AI 生成的內容不受理登記，而打一句提示詞——再長都一樣——不會讓你成為產出的作者。美國法院在「非人不能是作者」這個窄的點上也一致。
你貢獻的部分，用一般方式受保護。你寫的歌詞、劇本、把許多生成片段挑選編排成一件作品、大幅修改、你自己的聲音或表演、在算圖上重畫——這些是人的創作，就當人的創作處理。在美國是登記作品並聲明排除 AI 生成的部分；其他法域用不同路徑走到相近的地方（英國有一條專門的電腦生成作品規定、正在檢討中；歐盟和日本逐案看人的貢獻）。
平台條款疊在上面。能不能商用、平台是否保留一份授權、免費方案的產出是否另有待遇——全在你用的那個工具、你當時的方案、你使用那天的條款裡。去看現行版本；它們會改。
為什麼這讓你今天做的紀錄變得重要
注意上面每一個答案都繞著同一件事轉：人做了什麼、什麼時候做的。這是證據問題，而證據在當下最容易做、事後幾乎做不出來。半年後，沒有人——包括你——能重建你丟掉的是哪四十個版本、哪一段是你親手改寫的。
所以實務建議在每個法域都一樣：做完那天就把你的貢獻寫下來，並把日期釘住。著作紀錄裡的「人的貢獻」欄就是為此存在。它和檔案指紋、你的名字一起凍進紀錄，當晚上鏈，日後任何人都能查驗。它不決定你有沒有著作權；它是你拿給決定的人看的東西。
貢獻欄該怎麼寫
具體、保守、真實。「歌詞全部自己寫。在 Suno 生成約 40 個候選，選了一個，把橋段和最後一段副歌重排。主唱自己重錄。在 Logic 做母帶。」少用形容詞，列動作。如果誠實的版本是「下了提示詞、挑了一個」，就這麼寫——寫過頭的紀錄比沒有紀錄更糟，因為那是對方第一個會檢驗的地方。
Questions常見問題
If I wrote a very detailed prompt, am I the author of the image?如果我的提示詞寫得非常詳細，我是那張圖的作者嗎？
In the US Copyright Office's stated view, no — a prompt alone does not make you the author of the output, however detailed. Your authorship lies in what you did with the output: selection, arrangement, modification. Other jurisdictions vary.
依美國著作權局公開的立場，不是——單靠提示詞不會讓你成為產出的作者，再詳細都一樣。你的創作在於你對產出做了什麼：挑選、編排、修改。其他法域各有不同。
Does a blockchain record replace copyright registration?區塊鏈紀錄可以取代著作權登記嗎？
No. Where a government registration exists, it has legal effects a private record cannot have. A blockchain-anchored record is evidence of existence and of your stated contribution on a date; use it alongside registration, not instead.
不行。有政府登記制度的地方，登記有私人紀錄不可能有的法律效果。上鏈的紀錄是「某天已存在、以及你當時聲明的貢獻」的證據；和登記並用，不是取代。
What if the law changes?法律如果改了呢？
Then the question will still be what you did and when. A dated, verifiable statement of your contribution is useful under any rule that turns on human authorship — which is every rule so far.
問題仍然會是你做了什麼、什麼時候做的。一份有日期、可查驗的貢獻聲明，在任何以人的創作為判準的規則下都有用——到目前為止，每一條規則都是。
