About The Great Sage
Wisdom meets code — we make AI personal and under your control.
The Great Sage is the company behind the Janet ecosystem and J.A.N.E.T. Glasses — investor relations, campaigns, and the European glasses vision. We believe everyone deserves an AI companion that respects privacy and runs on hardware they own.
Janet is constitutional AI: 16 axioms, teachable runbooks, and cluster-only communication. She grows with you, works offline, and never sends your data to the cloud.

Questions & Answers
Common questions about Janet, The Great Sage, and how to get started.
Why Janet?
J.A.N.E.T. stands for Just A Neat Evolving Thinker. It describes what she is: an AI that keeps learning and adapting with you, not a fixed assistant. The name is memorable, works across languages like Japanese, and clearly sets her apart from Siri or Alexa. It's short, easy to say, and feels like a companion rather than a product.
What devices can I use Janet on?
Janet runs on your computer (janet-seed), then you connect from your phone (CallJanet for iOS), code editor (Janet Awakening in Cursor), smart home (Home Assistant), or future glasses. There are or will be native apps for iOS, watchOS, macOS, Windows, and Android. The vision includes Meta Quest. Right now you can see what's available at what-can-janet-do.pages.dev. Production-ready deployment is targeted for Q3 2026 if funding is successful.
What are the benefits of Janet?
Janet is built privacy-first. What that means is that your data stays on your devices and never goes to the cloud. You own your data. Janet works offline so you're not dependent on the internet. She follows a set of 16 rules that define her behavior. She's open source, so people can inspect and improve the code. The glasses add live captions, translation, and memory support, all running locally on your device. And there's no subscription — you pay once for the hardware and can optionally pay for support.
Why did you come up with Janet?
I wanted an alternative to the big tech assistants that rely on the cloud and monetize your data. J.A.N.E.T. — Just A Neat Evolving Thinker — is open, privacy-focused, works offline, and is built with accessibility in mind. The idea is to provide an alternative to Siri, Alexa, and Google with something you can own and trust. It's about giving people real choice instead of closed ecosystems that harvest your data.
How to use Janet?
You run the core brain (janet-seed) on your computer, then connect from your phone (CallJanet), code editor (Janet Awakening), or smart home. You say "Hey Janet!" to start and talk naturally — she supports both voice and text. When you're finished, say "Thank you, Janet!" or "Good night, Janet." The glasses will show live captions and translation right in your field of view, and all of that stays on your devices — nothing goes to the cloud.
Janet vs other AI?
Janet is meant to replace Siri, Alexa, and Google Assistant. She keeps your data on your devices, not in the cloud. She works offline, follows clear rules, and has no subscription. She's teachable — you can add runbooks and context. The glasses add accessibility features and are designed to be built in Europe in the future. Competitors rely on the cloud, subscriptions, and closed systems. Janet is open source, runs on your hardware, and you keep ownership of everything.
What are runbooks and how do they work?
A runbook is like a recipe or checklist for Janet. You write step-by-step instructions instead of code, and she follows them. For example, weather: check internet; if yes, look up the weather and answer in one sentence; if no, say you're offline. Or reminders: ask what and when, save it, then remind the user. Why it matters: no coding, you can change instructions later, you decide what she does in each situation, and she gets better as you add more runbooks. It's teaching her with simple steps instead of programming.
What would support for Janet mean to me?
Support could mean backing the Janet Glasses campaign on GoFundMe, adopting Janet in your daily life, or contributing to the project. The glasses aim to provide live captions, translation, and memory support — features that matter for accessibility. The campaign target is €5,000, with a deadline of May 1, 2026. Your support would help validate that people want privacy-first, future EU-made AI wearables that don't depend on subscriptions or the cloud.
Why open source?
Janet is open source, so anyone can inspect, modify, and share the code. That creates trust — no hidden behavior. People can add features, fix bugs, and make sure it's safe. The whole ecosystem, including the core brain (janet-seed), is open. That reduces vendor lock-in and lets the community shape the product instead of a single company.
Why no subscription?
Subscriptions tend to create lock-in and pressure companies to collect more data. Janet uses a one-time purchase model with optional support. The glasses are a single purchase with no monthly fee. That keeps costs predictable and avoids usage caps or paywalls for core features. You buy it once and you own it.
Why is privacy important?
Big tech companies collect and use your data. Janet is built so your data never leaves your devices. There's no cloud storage and no telemetry. We cannot access your conversations. The glasses process your voice locally so it doesn't go anywhere else. Privacy isn't an add-on — it's built into the design from the start, because your words and habits should stay yours.
Why pay for J.A.N.E.T.?
You don't have to. If you're tech-savvy, you can run Janet entirely for free — it's open source. Download janet-seed, connect your clients, and you're set. No subscription, no paywall.
So why pay at all? Two reasons. First: crowdfunding. If you back J.A.N.E.T. Glasses or similar campaigns, you're helping build the ecosystem — hardware, accessibility, EU-made products. Second: service. If you're not into tech, you pay for convenience. J.A.N.E.T. in a box, Janet Server, pre-set glasses — plug-and-play, fully set up. We handle installation and configuration so you get Janet without fiddling with servers or terminals.
Free if you do it yourself. Pay for support, hardware, or someone else doing the setup for you.
What are Janet Glasses?
Janet Glasses are AI smart glasses that run Janet — live captions, translation, and memory support right in your field of view. Phase 1 is Janet software on Brilliant Labs Halo hardware (JanetXHalo). The long-term goal is J.A.N.E.T. Glasses: our own hardware sourced and built in Europe, same features but Janet-native — offline, no subscription, constitutional AI. They're lightweight, all-day battery, and your voice never leaves your devices.
How do Janet Glasses help with accessibility?
Janet Glasses are built for accessibility first. They show live captions so you can read what's being said — for people who are deaf or hard of hearing. They do translation in real time for non-native speakers. And they support memory assist, so you can get gentle reminders and context without sending anything to the cloud. All of that runs locally on your devices. No subscription, no data harvesting.
I'm not a developer — can I still use Janet?
Yes. If you're not into tech, you don't have to run servers yourself. You can back the Janet Glasses campaign and eventually get plug-and-play glasses. Or you can pay for "Janet in a box" or Janet Server — someone sets everything up for you. If you are tech-savvy, you can run it all for free: download janet-seed, connect your phone or editor, and go. Either way, no monthly subscription for core Janet.
What are the 16 rules (axioms)?
Janet follows 16 constitutional axioms — rules that govern how she behaves. They cover things like telling the truth, respecting your privacy, not doing harmful things, and asking you before taking risky actions. One of them is Soul Check: for sensitive actions she'll ask for your confirmation instead of doing them automatically. The full list is in the project docs. The point is: her behavior is predictable and you're in control.
Can Janet do anything I ask?
She can do a lot — voice, text, file search, reminders, smart home, coding help. But she won't do things that break her rules. She won't lie, steal your data, or do harmful actions without your explicit confirmation. Soul Check is there so risky or sensitive steps need your okay. You're the one in charge; she's built to support you within clear boundaries.
Where is my data stored? Who can see my conversations?
Your data stays on your devices and in your Janet cluster — the computer and devices you run Janet on. There's no cloud. The team behind Janet can't access your conversations or your voice. The glasses process audio locally. So: you own it, and nobody else can see it unless you choose to share.
How much does it cost to get started?
To get started for free: download janet-seed and connect from your phone or code editor. No subscription. If you want hardware or someone else to set it up, you pay for that — for example backing the Janet Glasses GoFundMe (campaign target €5,000, deadline May 1, 2026) or buying a pre-configured Janet Server. The glasses are one-time purchase, no monthly fee. So: free if you do it yourself; you pay for convenience or to support the ecosystem.
Can I contribute to Janet?
Yes. The whole ecosystem is open source (GPL/MIT). The main repo is JANET on GitHub — janet-seed, CallJanet-iOS, Janet Awakening, JanetOS, and more. You can report bugs, suggest features, submit code, or improve docs. There's no vendor lock-in; the community helps shape what Janet becomes.
Why not just use ChatGPT or Siri?
ChatGPT and Siri send your data to the cloud and often require subscriptions or lock you into one company. Janet runs on your hardware, works offline, has no mandatory subscription, and you can teach her with runbooks. Your conversations stay yours. For young adults especially: you get an assistant you actually own, with no hidden data deals or monthly fees.
Who is The Great Sage?
The Great Sage is the company behind the Janet ecosystem and J.A.N.E.T. Glasses. Janet is the product. The Great Sage is the entity that brings it to market and runs efforts like the GoFundMe for the glasses.
What's next for Janet?
Short term: production-ready deployment (Q3 2026 if funding works), more apps and platforms, and the Janet Glasses Phase 1 campaign (software on Halo, then a pilot). Next: J.A.N.E.T. Glasses as our own European-sourced hardware — same privacy and no subscription, but built in the EU. The vision is a full ecosystem: OS, iOS, Android, Meta Quest, glasses, and smart home, all offline-first and under your control.
How can I back the glasses?
Back the Janet Glasses campaign on GoFundMe. The goal is €5,000 by May 1, 2026. Your support funds Halo units for development, JanetXHalo software (live captions and translation), an accessibility pilot, and a landing page for the ecosystem. It's Phase 1 validation: proving that Janet on glasses works before we build our own European hardware. Go to glasses.greatsage.org to support Janet Glasses.
