Subjectly โ€” AI Study Assistant That Respects Your Privacy Transform how you learn with an AI-powered study companion that keeps your documents completely private. Unlike other apps, Subjectly processes everything locally on your device โ€” your notes, research papers, and study materials never leave your phone. PRIVACY-FIRST DESIGN Your documents belong to you. Subjectly uses a local-first architecture where all document processing happens directly on your device. We never upload, store, or access your files. Your study materials stay exactly where they should โ€” with you. BRING YOUR OWN KEYS (BYOK) Pro subscribers connect their own AI API keys from OpenAI, Anthropic Claude, or Google Gemini. Your API keys are stored securely in your device's keychain and never transmitted to our servers. AI queries go directly from your device to your chosen provider โ€” we never see your data. You're in complete control of your AI usage and costs. FREE TIER Try AI-powered study features without your own API key. Free tier queries are processed through our secure proxy. Document excerpts used as AI context transit our servers during processing but are never stored or logged. Your full documents always remain on your device. HOW IT WORKS 1.

Understanding a language is one thing. Speaking it confidently is another. Vokli is built to help you turn what you know into words you can actually say. Listen to a question, respond out loud in the language you're learning, and get AI-powered feedback on your answer. See where you went wrong, learn a better way to say it, and try again, so speaking starts to feel more natural over time. With Vokli, you can: * Practice actually speaking, not just tapping through exercises * Respond to questions in your target language * Get AI feedback after you speak * See corrections and clearer ways to express yourself * Practice at different difficulty levels * Retry answers and learn from your mistakes * Build fluency through short, regular speaking practice You don't need to wait until your grammar is perfect. You don't need a teacher or conversation partner beside you every time you want to practice. Just listen, speak, get feedback, and improve. Whether you're trying to stop freezing mid-sentence, become more comfortable forming your own answers, or simply get more speaking practice, Vokli gives you a place to practice out loud. Speak more. Learn from every answer. Get better at actually using the language you know. Vokli requires a subscription to access premium speaking practice and AI feedback features.
