Copyright and AI Texts: What Fiction Authors Need to Know in 2026 — Before Publishing

You wrote a novel with AI assistance. Do you own it? Can you publish it? Do you need to disclose that AI was involved? And what happens if someone claims the AI plagiarized?

These questions are not academic. They are practical — and they affect every author who worked with AI in 2025 or 2026. The law always lags behind technology, and in the area of AI-generated content, the legal landscape in Germany, Austria and Switzerland is still evolving. But there are already clear principles, rulings and guidelines you need to know.

This article is not a legal opinion — it is well-founded guidance. For specific legal questions about your individual work, I always recommend consulting a specialized media law attorney.

The fundamental question: Who owns AI-generated text?

This is the crucial question — and the answer is more complicated than "the AI" or "the user."

European copyright law (and its national implementations in Germany, Austria and Switzerland) protects works that are the result of a personal intellectual creation by a human being. This is the core principle: copyright arises from human creativity. An AI is not a human. It cannot acquire copyright. Therefore, texts that were entirely generated by an AI, without human creative input, are not protected by copyright.

What does this mean for you as an author?

Scenario A: You wrote with AI (not: AI wrote for you)

If you developed the idea, planned the structure, created the characters, determined the tone — and AI helped you as a tool (brainstorming, rephrasing, consistency checking) — then the result is your personal intellectual creation. You are the author. The novel belongs to you. You have full copyright.

This is analogous to using other tools: An author who uses Grammarly remains the copyright holder. An author who uses Scrivener for structural planning remains the copyright holder. An author who uses EPOS-AI to check character consistency or evaluate and select scene suggestions remains the copyright holder.

Scenario B: AI generated most of the text

If you told the AI "write me chapter 5 about X" — and adopted the output without substantial editing of your own — the copyright situation becomes more difficult. The personal intellectual creation is missing. The text may not be eligible for copyright protection. This means: anyone could copy and use it without being legally liable to you.

This is a problem — especially if you publish that text and engage in commercial activity.

The 80/20 rule as a practical benchmark

There is no legally defined threshold for when an AI-assisted work becomes eligible for copyright protection. As a rule of thumb: the more you as a human have creatively shaped the work — idea, selection, editing, composition — the stronger your copyright. If you can say: 80% of my creative decisions are mine, the AI executed 20% (formulations, alternatives, technical consistency checks) — your copyright is virtually unassailable.

What do the courts say? Recent rulings 2024–2026

Courts are starting to take positions. Here are the most important developments that novel authors should know about:

USA: Copyright Office — AI-generated content not eligible for protection

The US Copyright Office has clarified in several decisions (2023, 2024): purely AI-generated content is not eligible for copyright protection. For works combining human creativity and AI assistance, the degree of human selection and creative input is decisive. The human contribution must be identifiable and creative.

EU: AI Act and copyright

The EU AI Act (in force since 2024) contains transparency obligations for AI-generated content — but no direct copyright regulations for literary works. The EU Commission is working on a framework for copyright in the AI context, expected for 2026/2027. Until then, national law applies.

Germany: Trends in case law

German courts have not yet directly addressed novel copyright with AI assistance. The general trend in legal scholarship: personal intellectual creation lies with the human who shapes the work — even when technical tools are used. AI as a writing tool is legally comparable to a word processor, as long as creative decision-making authority remains with the human.

Do I need to disclose that I used AI?

This is one of the most frequently asked questions — and the answer is nuanced.

With publishers and agents

A legal obligation to disclose AI use to publishers does not currently exist in Germany, Austria or Switzerland for AI-assisted works. However: more and more publishing contracts contain explicit clauses about the use of AI. If your contract includes such a clause and you violate it, this can lead to contract termination.

Practical recommendation: proactively ask your publisher or agent about their position on AI assistance — before you submit. It is better to address it openly than to conceal it and risk consequences later.

With readers

Under the AI Act, Germany has introduced a transparency obligation for mass AI-generated content. For a novel written with AI assistance (where human authorship is primary), this obligation typically does not apply. For a novel consisting predominantly of AI output, it might.

Regardless of legal obligations: many authors choose to include a note in the afterword for ethical reasons. This is a legitimate, respectful position — and does no harm when honestly worded.

With judges and competitions

The situation here is clear: most literary prizes and competitions introduced their own rules for AI in 2024 and 2025. Many exclude AI-assisted works — some accept them with disclosure. Always check the current terms of participation before submitting.

Copyright and training data: Can AI plagiarize?

A legitimate concern: what if the AI reproduces passages from copyrighted works during your writing process? Are you then responsible for plagiarism?

The answer is nuanced. Language models are trained on large text corpora — including copyrighted works. The legal debate about training itself has not been conclusively settled. But for you as an author: if an AI tool reproduces unmarked passages from existing books in your text, and you publish those passages, you could face liability.

How to protect yourself

Always run a plagiarism check before publishing. Free tools like Copyscape or PlagScan check your text against the public web. For more comprehensive checks against published books, specialized services exist. If a passage is flagged as suspicious: rewrite it entirely in your own words.

Important: a serious AI writing tool like EPOS-AI is designed to support text creation, not to reproduce existing text. The likelihood of direct text reproduction is low with writing assistance tools — but checking before publication remains good practice.

Data protection: Where do your unpublished chapters end up?

For authors, this is often more important than the pure copyright question: what happens to the text you upload to an AI tool?

American providers (OpenAI, Google, etc.)

The standard terms of service of many US-based AI providers allow the use of user data for model improvement — unless you explicitly opt out. This means: your unpublished novel chapters could flow into the training of future models. Additionally: processing takes place on US servers, which is relevant for EU citizens from a data protection perspective (GDPR).

European providers (EPOS-AI)

EPOS-AI processes all texts exclusively on Swiss servers, under the Swiss Data Protection Act (nDSG) and EU GDPR. No training with user data, no sharing with third parties. For unpublished literary works, where the timing of first publication is commercially relevant, this is a significant advantage.

Practical recommendations: How to protect yourself as an author

Document your creative work

Keep a simple writing journal during the writing process, or use the versioning features of your writing tool. This documents how the work evolved over time — shaped by your creative hand. In a dispute, a documented creation history is more valuable than an after-the-fact explanation.

Use AI as a tool, not as an author

Your strongest legal position is when AI clearly served a supporting function: consistency checks, rephrasing suggestions, brainstorming partner, structural analysis. The core creative work — idea, characters, tone, scene design, decisions about phrasing — lies with you.

Read the terms of service of your AI tool

Before working intensively with a tool: check the terms of service on three points. First: who owns the texts created with the tool? Serious tools like EPOS-AI transfer all rights to the user. Second: are your texts used for training? Third: where are your texts stored — EU/Switzerland or USA?

When approaching publishers: communicate proactively

If you know you worked with AI and plan to submit the novel to a publisher: clarify the publisher's position in advance. An honest answer to a question is always better than concealment that gets discovered later.

Specifics for the DACH market

Since EPOS-AI is a Swiss company and many users write in Switzerland, Germany and Austria, it is worth a brief look at the specific differences in these three legal systems.

Germany: UrhG and AI

The German Copyright Act (UrhG) protects personal intellectual creations. An AI is not a person and cannot create works. The Federal Court of Justice (BGH) has shown a tendency in similar cases (computer-generated works): human creative decisions are decisive. A novel written with AI assistance where the human author made creative decisions enjoys full copyright protection.

Austria: UrhG-AT

The Austrian Copyright Act is very similar to the German one. Here too: copyright arises from human creation. Austrian case law regarding AI works is even less developed than German law, but follows the same fundamental principles.

Switzerland: URG and nDSG

The Swiss Copyright Act (URG) shares the same fundamental principle: protection of human works. Additionally: the Swiss Data Protection Act (nDSG, in force since September 2023) is one of the strictest in Europe. It significantly strengthens users' rights to informational self-determination. EPOS-AI as a Swiss company is bound by the nDSG — a concrete data protection advantage for authors who want to protect their unpublished works.

What comes next: Keeping an eye on legal developments

Copyright law in the AI space will evolve significantly in the coming years. Three developments you should watch:

EU framework for AI and copyright: The EU Commission has announced plans to create a unified framework for copyright of AI-generated works. A draft directive is expected for 2026/2027. This could bring both obligations (labeling) and rights (clearer protectability of hybrid works).

Publishing industry standards: Major German publishers and the German Publishers and Booksellers Association (Börsenverein) are working on unified guidelines for AI-assisted works. What is currently handled differently from publisher to publisher will soon be standardized.

Judicial precedents: The first lawsuits involving AI-generated works will lead to landmark rulings in the coming years. Follow coverage in specialized media law publications.

Copyright and publishing contracts: What to watch when signing

When you sign a publishing contract, you transfer certain usage rights to your work to the publisher — but you remain the author. This is the fundamental distinction: authorship is inalienable. Usage rights can be transferred.

Watch for AI-specific clauses in publishing contracts, which have become more common since 2024. Some publishers require the author to guarantee that no AI was used in creating the work. If you wrote with AI assistance and sign this clause without addressing it, you risk contract termination or even damages claims in the worst case.

What to do? Clarify the question proactively — before you sign. Explain to the publisher concretely how you used AI: as a consistency checker, as a brainstorming partner, for style analysis. Many publishers do not fundamentally object to AI-assisted writing — they simply want transparency and assurance that the creative work comes from a human.

One more point: some publishing contracts now include clauses about who holds the rights to AI training data derived from the published work. This is a new legal territory that is developing rapidly. Read every contract carefully before signing — or have it reviewed by a media law attorney.

Conclusion: Legal certainty comes from smart practice

The good news: for authors who use AI as a tool and retain creative control, the legal situation is clear and fundamentally favorable. Your novel is your work — as long as you are the creative shaper.

The less good news: the industry is in flux, and what applies today may change tomorrow. The best strategy is therefore not to wait for a perfect legal landscape. The best strategy is to write informed: with clear documentation of your creative work, with tools that respect your data sovereignty, and with open communication toward publishers and readers.

That protects you. And it is the right thing to do.

The most important thing in one sentence: Be the creative shaper of your work. Use AI as a tool. Document your work. Communicate openly. Then your novel stands on solid ground — legally, ethically and creatively.
