AI Compare

Compare multiple LLM answers side by side, then synthesise insights.

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.
