How it works
- 1. Pick your models. Choose which AIs answer, from GPT and Claude to Gemini and more.
- 2. Send one prompt. MultiLens fans it out to every model in parallel.
- 3. Compare and synthesize. Read the answers side by side, or merge them into one.
Why ask more than one model
No single model is best at everything. One writes cleaner code, another reasons more carefully, a third has fresher information. Seeing the answers together shows where the models agree, which is usually a good sign, and where they differ, which is worth a closer look.
Frequently asked questions
- What is MultiLens?
- MultiLens is a multi-model AI chat app. You send one prompt and it asks several models at once (GPT, Claude, Gemini, and more), shows their answers side by side, and can synthesize them into one.
- Which AI models can I use?
- GPT from OpenAI, Claude from Anthropic, and Gemini from Google, plus more through OpenRouter. You can run several at once in a single conversation.
- What does synthesis do?
- Synthesis reads every model's reply and merges them into one combined answer, reconciling where they disagree, so you don't have to read each response in full.
- Is MultiLens free?
- There's a free tier to get started. Pro and Ultra plans add more models per prompt and higher monthly usage.
- Can I use it on mobile?
- Yes. MultiLens runs in the browser and as native iOS and Android apps.
