    TinyClaw

    TinyClaw

    The original Tiny Claw as your personal autonomous AI companion

    TinyClaw is an open-source autonomous AI companion framework designed to make personal AI agents simpler, cheaper to run, and more accessible to individual users. The project is built from scratch with a deliberately small native core and a modular plugin architecture that allows capabilities to expand without turning the system into a heavy monolith. Its philosophy centers on creating a persistent AI companion that behaves more like a helpful digital partner than a purely configurable assistant. TinyClaw incorporates self-improving memory and smart routing mechanisms intended to reduce large language model costs by tiering queries intelligently. The framework is designed to be self-configuring and easy to set up compared to more complex agent stacks, with a Bun-native runtime and built-in web interface. Overall, TinyClaw aims to democratize autonomous AI agents by delivering a lightweight, extensible, and personality-driven companion platform that evolves with the user over time.

    Lumo Android App

    Lumo Android App

    Android application for Proton Lumo

    Lumo Android App is the official Android client implementation of Lumo, a privacy-first AI assistant created by Proton that lets users interact with an intelligent chatbot securely and confidentially on mobile devices. Lumo is designed so that every conversation remains encrypted and private, meaning chats are not logged, tracked, or used to train external large language models, and all interactions are protected with zero-access encryption so only the user can read them. The Android app offers a responsive, native experience where users can ask questions, summarize documents, brainstorm ideas, or get help with tasks—while Proton’s strict privacy protections extend to the mobile interface. It integrates smoothly with Android’s system UI and supports features like voice input or clipboard sharing for convenience, while respecting user data control and transparency.

    Lumo iPhone App

    iOS application for Lumo

    Lumo iPhone App is the native iPhone and iPad client for Lumo, Proton’s privacy-centric AI assistant that allows users to ask questions, get summaries, generate content, and leverage AI help while keeping all conversations confidential and encrypted. Built with SwiftUI, the iOS app wraps a secure web-powered interface and communicates with the Lumo service in a way that ensures zero-access encryption, meaning even Proton cannot read or log user chats—only the device holder can decrypt them. It includes native features like on-device voice recording and speech recognition, flexible navigation, and payment integration for subscription plans if users choose expanded capabilities. The app’s architecture uses a combination of WebView and JavaScript bridges to power responsive chat UI while retaining strong data protection principles.
