ByoKey– AI Chat & API Hub

ByoKey is an AI chat for your own API key – and it shows you what your answers cost. You pay the AI provider directly, and only for what you use. ByoKey adds no subscription and no markup, and makes your costs visible. SEE WHAT YOU SPEND • Tokens and cost under each answer, wherever a price is known • Totals per chat, per project and per month • A monthly budget you set yourself, with a bar that shows how much of it is used • Compare before you choose: price per million tokens and context length for each model, where the provider's model list includes them • Your own prices for models without a listed price – otherwise ByoKey shows "Price unknown" rather than a wrong figure Amounts based on the provider's own figures are shown as they are; amounts that rest on an estimated token count or on a price you entered are marked "approx.". YOUR KEY, YOUR CHOICE • 15 AI providers, including providers that process data in the EU – or a server of your own, also on your local network • Compatible with API keys from OpenRouter, OpenAI, Anthropic, Google Gemini, Mistral AI and more • Connect with OpenRouter: sign in instead of copying a key – or start with free models (daily limits apply) • Your keys are stored only on this device and are sent only to the provider they belong to • Nothing goes to a provider before you agree – separately for each provider BUILT FOR REAL WORK • Projects with their own instructions and default model • Attach PDFs, text and code files, and images • Create images with the image models of selected providers • Tables and code blocks in answers; export source files or preview HTML on your device • Voice mode: speak and have answers read aloud. On your device it works with any model; via the provider it needs that provider's models for speech recognition and speech output – only some providers offer them • Unsent text stays with each chat while the app is open • Choose the default model for new chats SAFE BY DESIGN • An on-device content filter checks requests and answers • Report content and block models right in the chat • No account with us, no tracking, no ads • In English, German and Polish Free – no in-app purchases, no subscription. Note: ByoKey requires your own API key from a third-party AI provider (for example OpenRouter) or a server of your own. The provider bills you directly for using its models. ByoKey sells no credit, receives no commission and runs no server that your chat requests pass through.
