About this app

LookinGlass is multi-model AI chat. Ask the world's best language models the same question — Claude and GPT-4o — and decide for yourself which answer is better. Compare reasoning side by side, or get a single synthesized answer.

Three ways to think

• Standard — focused chat with one model
• Parallel — same prompt sent to Claude and GPT-4o at once, color-coded so you can compare reasoning side by side
• Bash — every provider runs in parallel, then Claude synthesizes the best of each into one clear answer

Built for clarity

A single horizontal waveform is your entire interface. It listens while you type, ripples while it thinks, settles when it's done. No avatars, no clutter, no chrome.

Everything stays with you

• Persistent history across web and mobile — every conversation survives a reinstall, a device switch, a sign-out
• Search every word you've ever sent, plus the facts LookinGlass auto-remembers about you
• Personal projects — pin a system prompt to a project and every chat inside it inherits your rules
• Drop in a PDF, Word doc, spreadsheet, or PowerPoint and ask about its contents
• Auto-titled threads, edit-and-resend, copy and regenerate — every modern-chat affordance, none of the noise

• Mermaid diagrams — flowcharts render as actual visuals
