Why Choose Babilo?

Traditional language apps sell your data and charge you every month. Babilo flips the script with local-first AI that's free for everyone.

shield_lock

100% Private & Offline

Your voice and data never leave your machine. By running Gemma 4 locally via Vulkan, Babilo ensures total linguistic privacy without needing an internet connection.

code_blocks

GPLv3 Open Source

Transparency you can trust. Our core logic is open to the community, ensuring the project remains ethical, auditable, and free from corporate data-mining.

download

Free & Open Source

No gated features, no hidden tiers. Babilo is fully open source under GPLv3 and available to download free on GitHub. Build it, fork it, or just use it.

speed

No Latency, No Limits

Engineered in Rust for immediate response times. Practice conversations in real-time with neural synthesis that reacts as fast as a human tutor.

Free vs. Paid

Why pay monthly when the best language AI is free and open source?

Frequently Asked Questions

Clear answers for learners and developers alike.

How can Babilo run Gemma 4 locally without lag? expand_more

We utilize the Vulkan API and custom Rust bindings to orchestrate GPU VRAM directly. By using 4-bit quantization and native multimodal processing, we bypass the heavy overhead of traditional Python-based AI stacks.

Is Babilo really free? expand_more

Yes. Babilo is fully open source under GPLv3 and free to download from GitHub. No subscriptions, no tokens, no 'Pro' tiers. Your hardware does the work, so there are no compute costs for anyone.

What languages will be supported at launch? expand_more

Thanks to Gemma 4's multilingual capabilities and Supertonic's polyglot synthesis, Babilo will launch with full support for Spanish, English, French and German with more being optimized post-launch.

Does Babilo require an internet connection? expand_more

Only for the initial download and updates. Once installed, the entire neural engine, STT, and TTS systems run 100% offline. Your data never touches a cloud server.

Can I use Babilo if I don't have a high-end Gaming PC? expand_more

While a dedicated GPU (NVIDIA/AMD) provides the best experience, our Vulkan-based optimization allows Babilo to run efficiently on modern integrated graphics and Apple Silicon (M-series) chips.
