Byoky is a wallet for your AI API keys. Keep your OpenAI, Anthropic, Gemini and other AI keys in one encrypted wallet on your iPhone or iPad. Apps connect to the wallet, you approve, and Byoky makes the API calls for them. The app never sees your key. WORKS IN SAFARI The Byoky Safari extension brings the wallet to Safari. Add keys in its popup, and websites that support Byoky can use them, just like the desktop extension. BUILT-IN BROWSER Open any web app inside Byoky by its address. It connects to your wallet automatically, with no extension needed. ONE WALLET, EVERY PROVIDER Anthropic (API keys and Claude setup tokens), OpenAI, Google Gemini, Mistral, Cohere, xAI, DeepSeek, Perplexity, Groq, Together AI, Fireworks, OpenRouter, Azure OpenAI and custom endpoints. YOU STAY IN CONTROL โ€ข Approve every app before it connects. โ€ข See every request and token count. โ€ข Set allowances, and revoke access any time. โ€ข Groups and cross-provider routing: move an app from Claude to GPT without the app changing a line. NO SERVERS No account. No cloud. No tracking. Keys are encrypted and stored in the iOS Keychain. Requests go straight from your phone to the provider. Move keys between devices with password-protected .byoky backup files. OPEN SOURCE MIT-licensed on GitHub: github.com/MichaelLod/byoky

Prismara puts the best AI models in one fast, native iPhone app. Subscribe for a monthly pool of credits, then chat with 300+ models from leading providers, and switch between them in a single tap from the corner picker. Built entirely in SwiftUI with no third-party analytics SDKs, Prismara is lightweight, private, and quick to launch. WHAT YOU CAN DO - Chat with 300+ models: pick any model from the live, searchable catalog, with favorites and badges for price, context length, and vision support. - Switch models on the fly: change the model mid-conversation from the chat toolbar. - Stream responses token by token: with markdown, code blocks, copy and regenerate, a reasoning disclosure, and live token and cost readouts. - Attach images, photos, and PDFs: captured or chosen from your library, automatically downscaled and sent to vision-capable models. - Tune your setup: set a default model, temperature, and system prompt, and track your credit balance. PRIVATE BY DESIGN Your conversations are stored only on your device. Prismara includes no advertising, tracking, or third-party analytics SDKs. The messages you send are processed by the AI providers you choose to generate responses; the developer keeps no copy of your chats. SUBSCRIPTIONS Prismara offers optional auto-renewable monthly subscriptions, each including a pool of credits you can spend across every model: - Plus: 4,000 credits per month ($2.99) - Pro: 10,000 credits per month ($7.99) A free tier with a smaller monthly credit allowance is included, so you can try Prismara before subscribing. Credits are spent based on the model you choose and the length of each response. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel anytime in iOS Settings under Apple Account, then Subscriptions. Privacy Policy: https://www.prismara-ai.app/privacy Terms of Use: https://www.prismara-ai.app/terms
