AI Compare

AI Compare lets you send one prompt to multiple leading AI providers and view their responses side by side. • SINGLE MODE Chat with one provider at a time. Switch models on the fly, attach images or documents, and review full conversation history. • COMPARE MODE Send the same prompt to all configured providers simultaneously. See each model's answer in parallel columns, complete with streaming text, generated images, token counts, and estimated API costs. • SYNTHESIS After gathering responses, tap Synthesise to let an AI summarise consensus, disagreements, unique claims, and potentially questionable statements. Export the synthesis or any provider's thread as a searchable PDF. • MULTI-MODEL SUPPORT Fetch available models directly from each provider's API. The app caches model lists so switching providers is instant. • ATTACHMENTS Drag-and-drop images on macOS or use the photo picker on iOS. Supported files are automatically resized and converted to JPEG for efficient upload. • TOKEN TRACKING View input/output token counts per message. Usage Stats shows rolling totals for the last 24 hours, 7 days, and 30 days, with cost estimates based on public pricing. • SECURE KEY STORAGE API keys are stored in the system Keychain, not in plain text. • NATIVE EXPERIENCE Built with SwiftUI for macOS and iOS. Conversations sync locally via SwiftData; no external account required. Requires your own API keys from Google AI (Gemini), OpenAI, Anthropic, or xAI. Network access is needed to reach each provider's API.
