Plura is a bring-your-own-key (BYOK) client for major AI models. Configure your own provider credentials, choose a model, and work across text, images, voice, search, and multiple providers in one app. Before Plura sends disclosed data or a provider credential to any external AI or search service, it identifies the actual receiving operator and destination, explains the purpose and data categories, links the available privacy policy, and asks for explicit permission. • Multiple providers: OpenAI-compatible services, Anthropic Claude, Google Gemini, DeepSeek, and local Ollama • Auto routing: choose a suitable model based on the request • Model council and comparison: ask several models and compare or synthesize their responses • Image generation and vision: create images or select a photo for an authorized provider to analyze • Optional web search using your own Tavily, Brave Search, or Serper key • Long-term memory, summaries, and cross-session retrieval, controlled in Settings • Voice input and read-aloud • Per-provider token and cost reporting • On-device Apple Foundation Models on supported devices Privacy controls: • Provider credentials are stored in the iOS Keychain; conversations, settings, memories, and consent decisions are stored locally • External transmissions occur only after the user authorizes the displayed recipient and scope • Public custom endpoints must use HTTPS and disclose their real operator and privacy policy where required • Changing a provider's endpoint, operator, policy, relationship, or disclosure requires a new decision • Permissions can be reviewed or revoked under Settings → Privacy • No advertising, analytics, or tracking SDKs Plura 1.0 is free and contains no in-app purchases.
