Terms of Service

Last updated: 2026-07-25 · Version: 1.0-draft

0. Read this first — what these Terms do and do not cover

libi is free and open source software licensed under the GNU General Public License, version 3 only (GPL-3.0-only).

The LICENSE governs the software. These Terms do not.

Your rights to run, study, modify, copy and redistribute libi come from the GPL and from nothing else. Nothing here restricts, conditions or reduces those rights. If any provision of these Terms would operate as a "further restriction" within the meaning of section 10 of the GPL, that provision does not apply to the software and you may disregard it.

These Terms govern only (1) this website, and (2) any optional hosted services we may offer in future (§10), which are separate commercial products not covered by the GPL.

You never need to accept these Terms to download, install, run, fork or redistribute libi.

1. Who we are

libi is operated by Nadav Nagel, an individual sole proprietor in Israel ("we", "us"), at admin@nagellabs.com. By using this website or any hosted service you agree to these Terms. If you do not agree, do not use them — the software remains available to you under the GPL regardless. You must be at least 16, or the age of digital consent where you live.

2. The software: GPL-3.0-only

You may use libi for any purpose, including commercially; study and modify the source; and redistribute original or modified versions, provided you pass on the source under the same licence and preserve the notices. The licence text controls over this summary.

libi is free to use, and complete without paying anything. The editor, the agent integration, every export path and every feature described in our documentation are available at no cost, with no account, no trial period and no seat limit. libi Pro (§10) is an entirely optional paid membership that adds cloud services on top; it does not unlock anything in the app and nothing in the free product is withheld pending payment.

Whether you pay or not, you use libi at your own risk. Paying for libi Pro buys you optional cloud services — it does not buy a warranty, a guarantee of results, or an assumption of liability for what the software does on your machine. §§8 and 9 apply in full to free and paid use alike.

We impose no additional restriction on those rights. We do not restrict who may use libi or for what, and we do not require attribution beyond what the GPL requires.

Trademarks are separate from copyright. The name "libi" and the libi logo are not licensed under the GPL. You may accurately state that your project is based on libi. You may not use our name or logo in a way suggesting your fork is official or endorsed by us. This reflects GPLv3 §7(e), which expressly permits declining to grant trademark rights.

Bundled third-party components — including ffmpeg, ffprobe, yt-dlp and machine-learning models — are covered by their own licences, not ours.

3. You bring your own keys

libi includes no AI credits and we do not resell model access. You supply your own credentials for services such as fal.ai and ElevenLabs, and your own subscription to a CLI coding agent.

• libi calls those providers directly from your computer using your key. We never receive, proxy, store or see your keys, requests or responses.
• You are bound by each provider's own terms and pricing, and are solely responsible for charges you incur. libi asks you to approve paid operations before running them, but the spend is yours.
• We are not responsible for a provider changing pricing, deprecating a model, refusing a prompt, suspending your account, or producing an unexpected output.

4. Your content and AI output

You own everything you create with libi. We claim no ownership of and no licence to your footage, projects, prompts or outputs. We could not claim them if we wanted to — they never reach us.

Ownership of AI output is legally unsettled and differs by country; some jurisdictions decline copyright to purely machine-generated material. We make no representation that you own, can protect, or can safely commercialise anything libi's AI features generate.

You are responsible for what you generate. libi is a tool that follows your instructions. You are solely responsible for what you make and what you do with it — including whether it infringes copyright, defames someone, uses a person's likeness or voice without rights, breaches a platform's rules, or is unlawful where you or your audience are. We do not review, moderate or host your output. We cannot — it never reaches us.

5. Synthetic media, likeness and voice

libi can generate realistic images, video and speech. That carries risk you carry, not us:

• Never create sexual content involving minors.
• Never create non-consensual intimate imagery of a real person.
• Do not clone a real person's voice or likeness without documented consent. Many countries grant enforceable personality and image rights.
• Do not create synthetic media intended to deceive about elections, public health or safety, or to impersonate someone for fraud.

Labelling obligation. From 2 August 2026, Article 50(4) of the EU AI Act requires deployers of AI systems generating deep-fake content to disclose that it is artificially generated. If you publish synthetic media to an EU audience, that obligation is yours as the deployer, and it applies even without intent to deceive. TikTok, Instagram, YouTube and X impose their own AI-disclosure rules. Comply with them.

6. Downloading from third-party platforms (yt-dlp)

libi bundles yt-dlp, an independent tool that can download media from web platforms. We do not operate or control those platforms, and this is a real exposure worth understanding:

• Platform terms typically prohibit downloading. Doing so can breach your contract with that platform and get your account suspended.
• Downloading may separately infringe copyright, depending on the work and your country's rules.
• Legitimate uses exist — your own uploads, works you licensed, public-domain material, platform-authorised exports, and uses covered by an exception where you live.

You are solely responsible for ensuring you have the right to download any material. We provide the tool; we do not authorise or encourage infringing use, and we accept no liability for how you use it. If you are unsure whether a download is lawful where you live, don't.

7. Acceptable use of this website and hosted services

(This applies to our website and hosted services only. It is not, and cannot be, a restriction on the GPL-licensed software — see §0.)

Do not: attempt unauthorised access to our systems or another user's data; probe or test our infrastructure without written permission; interfere with or overload the service; distribute malware or unlawful content; misrepresent yourself as us; or break any applicable law.

We may suspend access to the website or hosted services for serious or repeated breach. This never affects your GPL rights in the software, which we cannot terminate.

8. No warranty

libi is provided "AS IS", without warranty of any kind. For the software, sections 15 and 16 of the GPL apply directly and control — including the disclaimer of merchantability and fitness for a particular purpose, and the statement that the entire risk as to quality and performance is with you.

For this website and any free hosted service we disclaim all warranties to the fullest extent the law allows. We do not warrant that libi will be error-free, that it will not lose or corrupt data, or that any AI output will be accurate, appropriate or lawful.

Back up your work. libi stores everything locally and edits media files.

Consumer rights are unaffected. Nothing here excludes rights you have as a consumer that cannot lawfully be excluded, including under Israel's Consumer Protection Law, 5741-1981 or, where applicable, EU and UK consumer law.

9. Limitation of liability and indemnity

Nothing limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot lawfully be limited. Where local consumer law gives you stronger protection, that law prevails.

This section applies equally to free use and to paid libi Pro use. Paying for a subscription does not increase what we take responsibility for; it buys optional cloud services, not a warranty.

Subject to that, and to the fullest extent permitted:

• You use libi at your own risk, in both tiers. We accept no liability for how the software behaves on your machine, for anything you create with it, for what you do with the result, or for any loss — of data, work, time, money or opportunity — arising from using it.
• For the software, GPL section 16 applies and controls, including its exclusion of liability for loss of data.
• We are not liable for indirect, incidental, special or consequential damages; lost profits, revenue, goodwill or data; API charges you incur with third parties; the output of any AI model; or claims arising from content you downloaded.
• Our total aggregate liability for the website or any free service is limited to [USD 100]. For a paid service it is limited to what you actually paid us in the 12 months before the event.

These limits reflect a deliberate allocation of risk: libi is given away free by one person, and the price reflects the absence of any assumption of liability.

Indemnity. If someone brings a claim against us because of what you did — content you generated or published, media you downloaded, a likeness or voice you used, or your breach of these Terms — you agree to defend and indemnify us, including reasonable legal costs. We will tell you promptly, will not settle without your consent, and will let you control the defence. This does not apply where the claim arises from our own breach or negligence, nor to the extent prohibited by consumer law where you live.

10. Paid and hosted services (future)

These do not exist yet. This describes terms that will apply if and when we launch libi Pro. The free software remains fully functional without it.

• Not covered by the GPL. Hosted services are proprietary network services; a subscription grants no rights in their source code.
• Billing. Billed in advance. We will give 30 days' notice before any price increase.
• Cancellation, and your Israeli statutory rights. libi Pro is an ongoing transaction (עסקה מתמשכת) under the Consumer Protection Law, 5741-1981, which gives you rights we cannot contract away:
• a 14-day right to cancel, which applies whether or not the service has already commenced (§14ג(ג)(2)) — extended to 4 months for people with disabilities, those aged 65+, and new immigrants within 5 years, where the sale involved a conversation;
• cancellation online, through a prominent link, and as easy as signing up was — we will ask only for your name and ID number, never a reason or a retention call;
• the contract ends within 3 business days of your notice, after which we stop supply and charge you nothing further;
• any cancellation fee is capped at 5% of the price or NIS 100, whichever is lower, and is zero where you cancel because of a defect or our breach.
• Renewal. For Israeli consumers, an automatic-renewal clause in a fixed-term contract has no legal effect under §13א — so a fixed-term plan simply ends on its date unless you actively renew. We intend to offer monthly rolling plans, which sidestep this entirely.
• Refunds. [STATE POLICY]. Statutory withdrawal and cancellation rights apply notwithstanding anything here.
• Availability. No service-level agreement unless separately agreed in writing.
• Termination and your data. On termination we will make your stored content available for export for at least 30 days, then delete it. Your local ~/.libi/ data is unaffected — libi keeps working offline.

11. Copyright complaints

We do not host user content. If you believe material on this website infringes your copyright, email admin@nagellabs.com with: identification of the work, the URL, your contact details, a statement of good-faith belief that the use is unauthorised, and a statement that your information is accurate and you are authorised to act.

12. Governing law and disputes

These Terms are governed by the laws of the State of Israel, and the competent courts of Tel Aviv-Jaffa have exclusive jurisdiction — except as set out below.

Consumers. If you use libi as a consumer and live in the EEA, the UK, or another country whose law lets you bring proceedings locally, nothing here removes that right, and you keep the protection of the mandatory consumer law of your country of residence.

Before formal proceedings, please email admin@nagellabs.com. Most problems are a misunderstanding and can be sorted out in a day.

13. General

Changes. Material changes take effect 30 days after we post them here with a new date. Changes to these Terms never change the GPL licence on the software, and never apply retroactively to a version you already have.

Severability. If a provision is unenforceable the rest stands. In particular, if any provision would be a "further restriction" under GPL §10, it is severed as to the software.

Assignment. You may not assign these Terms. We may assign them to a successor or to an entity formed to operate libi, on notice to you.

Entire agreement. These Terms, the Privacy Policy, and — for the software — the GPL, are the entire agreement between us.
