Prismara vs Reactive Playground

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

Reactive Playground is a visual learning app for reactive programming. Instead of reading operator definitions only, you can play with marble timelines directly. Pick a category, open an operator, move events around, edit their values, clone items, remove them, or turn them into errors and completed events. The output updates live so you can understand what each operator really does. Explore operator categories such as: Transforming Filtering Combining Error Handling Utility Each playground shows a source timeline, an output timeline, a short explanation, and a code-style example. It is useful for learning ReactiveX concepts, reviewing operators, or quickly refreshing how a stream behaves before using it in code. Reactive Playground is made for developers, students, and anyone learning Rx-style reactive programming.
