AI access is built on data collection and privacy exploitation. LAVA changes that.
Cloud AI bills you monthly, token limits and train on your conversations, your uploaded private documents. LAVA flips that: the model lives on your device, so there is nothing to upload, nothing to bill, nothing to collect and nothing to leak.
“AI is one of the most profound things humanity is working on. It is more profound than fire or electricity.”
- Sundar Pichai, CEO of Google“Privacy is a fundamental human right.”
- Tim Cook, CEO of Apple“Saying you don't care about privacy because you have nothing to hide is like saying you don't care about free speech because you have nothing to say.”

Short answers
FAQ.
What is LAVA?
LAVA (Local AI Voice Assistant) is a free Chrome extension that runs AI on-device with Chrome built-in Gemini Nano, and full voice support. It answers by text and voice, calibrate mic and enable hands-free mode just say “Hey LAVA”, or just click the mic for simple voice use, or type using keyboard. Includes study playbooks, resume improvement help, translation, and talk-to-any-page.
Is my voice and data private?
Yes. Everything is processed on your device and stays on your own device, cleared by deleteting browser history/cache. No backend AI server, zero telemetry, hence no data collection, no training on your chats. That is the whole point of on-device/local AI.
Does it work offline?
Yes. Chrome downloads the on-device model once (needs internet). After that, disconnect Wi-Fi — LAVA still answers, translates, and reads aloud.
Is it really free and unlimited?
Yes. No signup, no tokens, no subscriptions, no API keys. On-device inference has no server cost per question, so chat as much as you want, even offline.
How is LAVA different from ChatGPT, Gemini or Claude?
Cloud AIs run giant models on vendor servers: they need internet, accounts, and often subscriptions, and prompts leave your device. LAVA runs a compact model inside your browser: instant, private, offline, unlimited — ideal for study, writing, translation, and daily voice tasks.
What do I need to run it?
Desktop Chrome with built-in AI (Gemini Nano) on Windows, macOS, Linux or ChromeOS, plus a mic and speaker. Install LAVA, let the model download finish, open Hands-Free mode and press Calibrate once.
Which languages are supported? Is Hindi supported?
15 languages for voice + text with spoken read-back using OS voice packs. Yes — including Hindi, English, Spanish, French, German, Portuguese and more. Speak in one language, have LAVA translate and read back in another, or use it to practice.
What can I actually do with it?
Hands-free Q&A with “Hey LAVA” even in the background. Study playbooks that simplify topics and build quizzes. Writing help for posts, emails, essays, resumes. Select text on any page or open a PDF and talk about it. Save to PDF or print.
How do I talk to it?
Three ways: say “Hey LAVA” (hands-free), click the mic and speak in 15 languages, or type and choose answer length. All three give typed + spoken answers.
Does it work in airplane mode / with no Wi-Fi?
Yes, after the one-time model download. Students use it on flights, campuses, and rural classrooms with no connection.
Is LAVA safe for use?
Outputs are AI-generated locally on your device using Google Chrome's built-in Gemini Nano model, which LAVA does not provide, own, control, or warrant - LAVA only interfaces with it via Chrome's Built-in AI APIs, and such small on-device models can make mistakes for fact checking, hallucinate, or provide incomplete information and even error information, so you must verify important facts from authoritative sources and must not rely on LAVA for high stakes medical, legal, financial, mathematical, programming, or other professional advice or decisions, with LAVA/FIG providing the extension "as is" without warranties and, to the maximum extent permitted by law, accepting no liability for generated outputs or any actions taken based on them.
Why free? What’s the catch?
No catch. There is no cloud bill to pass on because inference happens on your device. FIG builds lightweight privacy first software; LAVA is free worldwide on the Chrome Web Store with more on-device features planned.
