Compare GPT, Gemini, Claude & Grok answers side by side, then synthesise insights.
AI Compare lets you send one prompt to multiple leading AI providers—Gemini, ChatGPT, Claude, and Grok—and view their responses side by side. Whether you're researching, writing, coding, or just curious about how different models think, AI Compare gives you the complete picture in one unified interface.
- 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.
