Terms & Conditions

These terms govern your use of Esbi, a voice and text assistant for Android made by StareBrain, your Esbi account, and this website. By creating an account, installing or using the app, or using this website, you agree to them and to our Privacy Policy. If you don't agree, don't use Esbi.

Esbi is in early access. Features, workflows and behavior described here and on the site may change.

You give Esbi a command by voice or text. For everyday commands — calling or texting a contact, setting an alarm, opening an app, changing a setting — it acts directly on your phone. For larger tasks inside other apps, it uses Android's Accessibility service to read the screen and tap, type and scroll for you, and tells you what it is doing as it goes.

Esbi asks before it sends a text, and the agent always asks before sending, paying or deleting inside other apps. You can stop a running task at any time with the Stop button on the status card or by saying “stop”. You can switch on “Run commands without asking first” to skip the confirmation card for ordinary commands; it is off by default, and you are responsible for what you choose to run without a prompt.

Esbi cannot open your photos, videos or documents — this is enforced in the app's code — so it can't perform tasks that need them, and it never reads, copies or sends them.

Capabilities may be added, changed or removed over time.

To use Esbi you need to sign up for an account with your email address and a password, and, if we have switched on invite-only sign-up, a valid invite code. You must give accurate information, keep your login details secure, and tell us if you think someone else has access to your account. You're responsible for activity under your account and for keeping your device secure.

You must be at least 13 years old, and old enough under the law where you live to agree to these terms on your own. If you believe a minor is using Esbi without appropriate consent, contact us and we'll act on it. You can delete your account at any time in the app under Settings → Account.

Esbi only acts within the permissions you have granted in Android's settings and the app. You can revoke any of them at any time, and Esbi then stops being able to do that kind of thing.

You're responsible for what you ask Esbi to do and for checking a confirmation before you approve it. Esbi describes what it is about to do in good faith, but you are the one approving the action.

Don't use Esbi to send messages, place calls, or take any action you wouldn't be allowed to take yourself — including harassment, spam, impersonation, or anything illegal where you live.

Don't attempt to bypass Esbi's safety checks or the restriction on opening photos, videos and documents, reverse-engineer the app, overload the service, access another person's account, or use Esbi in a way that could disrupt it for others.

We can suspend or close accounts that violate this section.

The AI services behind Esbi have limited free capacity that all users share. To keep Esbi available to everyone, each account has daily limits on the requests that use those services (for example agent steps and cloud voice recognition). When you reach a limit, Esbi tells you in plain words and those features resume the next day. Everyday commands that run on your phone, such as calls, alarms and opening apps, are not affected. We may change the limits at any time.

To understand a command or the next step of a task, the app sends it to our server, which forwards it to third-party AI providers — currently Groq, NVIDIA (NVIDIA NIM), OpenRouter, Google Gemini and Ollama Cloud — as described in our Privacy Policy. What's sent can include the text of your command, a short recording of your voice when cloud recognition is used, a short list of names to help spell them correctly, and a text description of what appears on your screen while a task runs (the “screen log”). We can process these requests on our server, and the providers can see them too.

Because the screen log reflects what's on your screen, it can include content from other apps and from other people. Avoid having passwords, payment details or other sensitive information on screen while you use the agent, and don't use it where you aren't allowed to share that content. The providers are independent companies; we don't control their systems, and their own terms and privacy policies govern what they do with the content they receive.

Esbi acts on your behalf in other apps and services on your phone, such as messaging, calendar and video apps. Your use of those is still governed by their own terms, and we're not responsible for them. AI output can be wrong, incomplete or out of date, so check what Esbi proposes before you approve it.

You keep ownership of what you say or type and of the information on your phone. You give us, and the providers described above, permission to process your commands, recordings and screen log as needed to understand them, run and secure the service, and fix problems.

You're responsible for your commands and for the people and services you direct Esbi to contact — including having the right to send any message it sends on your behalf.

Esbi, StareBrain, their names, logos, software and website content belong to StareBrain and its licensors. While you comply with these terms, you have a personal, non-exclusive, non-transferable, revocable licence to install and use the app on your own devices.

Nothing in these terms transfers any ownership of our intellectual property to you. If you send us feedback or ideas, we may use them without obligation to you.

Joining the waitlist reserves your interest only. It isn't a purchase, a guarantee of access, or a promise of a launch date. We'll email waitlist members once at launch, and you can ask us to remove you at any time.

Things you send through our contact and investor forms are handled as described in the Privacy Policy. Information on this website, including any figures or timelines, is for general information and may change; nothing on it is an offer or investment advice.

Esbi is provided as-is and as-available, especially during early access. We aim for commands to succeed the large majority of the time, but speech and language understanding aren't perfect, and apps change in ways that can stop a task from working. Always watch the confirmation prompts and stop a task if it does something you didn't intend.

We don't guarantee the app will be uninterrupted, error-free, secure from every threat, or fit for any particular purpose beyond what's described here. We also don't guarantee the availability or output of third-party AI providers or hosting services.

To the extent allowed by law, StareBrain and its creators aren't liable for indirect, incidental, or consequential damages arising from your use of the app — including a message sent, a call placed, an event booked, or an action taken in another app that you approved or chose to run without a prompt, content visible on your screen that was included in a request, a misheard name or command, or an outage or error at a third-party provider.

Nothing here limits liability where the law doesn't allow it to be limited.

We're actively building Esbi and may add, change, or remove commands and features as the product develops. We'll update the date at the top of this page and flag material changes to these terms in the app before they take effect. Continuing to use Esbi after that means you accept the updated terms.

You can stop using Esbi, uninstall it, and delete your account at any time. We may suspend or close your account if you violate these terms or misuse the service. Sections that by their nature should continue — such as intellectual property, no warranty and limitation of liability — continue after termination.

These terms are governed by the laws that apply where StareBrain's operator is established, without regard to conflict-of-law rules. If a dispute arises, please contact us first so we can try to resolve it informally. Any dispute we can't resolve that way will be handled by the courts that have jurisdiction there, except where your local law gives you the right to bring a claim where you live.

These terms and the Privacy Policy are the whole agreement between you and us about Esbi. If part of these terms can't be enforced, the rest still applies. If we don't enforce a right straight away, that doesn't mean we've given it up.
