Ithy: Combine Deep Research AI

Ithy is an AI research assistant that combines findings from multiple AI models into one report. Ask a question once, compare AI answers side by side, and read the combined answer. If you usually open several tabs for multi AI chat, you can start with one question in Ithy.

DEEP RESEARCH
In Deep Research, several AI models investigate the same question independently. The team varies by mode and can include ChatGPT, Claude, Gemini or DeepSeek. Ithy combines their findings and keeps their individual responses available, so you can compare AI answers and see where the models agree or take different approaches.

AI SEARCH ENGINE WITH SOURCES
Use Ithy as an AI search engine when you want to explore a topic and check the evidence. Fast Research gives you a focused starting point. Choose Deep Research when the question needs a wider investigation. Open the links beside important claims and use tables, diagrams, images or videos when they help explain the findings.

FROM SEPARATE ANSWERS TO ONE REPORT
If you use multi AI chat to check how different models approach a question, try the same question in Ithy. The AI research assistant pulls the findings into one report so you can read the synthesis and still inspect the original responses. Compare AI answers when a difference matters, then check the linked sources before relying on it.

RESEARCH YOU CAN COME BACK TO
Use the AI search engine to explore an unfamiliar topic, compare options or investigate a technical question. Keep useful answers in your library, organize them into folders and share or export a report. Set a writing style for the AI research assistant. Where multi AI chat leaves several responses to revisit, Ithy lets you save the combined report as one item.

READ OFFLINE
Save completed answers for offline reading. Search your saved answers, adjust text size and share useful passages. Offline copies stay on your device. Videos and interactive charts are available in the online answer. The AI search engine needs an internet connection.

RESEARCH REWARDS
Earn points as you research and share. Reach Silver to discover your available member reward. A qualifying paid referral earns 25,000 points, enough for 25 research answers. See reward eligibility in your account.

GO FURTHER WITH PRO
Pro includes premium AI models and Unlimited Deep Research. Paid Pro also includes 1,000 API requests each month for your own tools, separate from research on the website and in the app. Subscription prices and renewal terms appear before purchase. Manage app subscriptions in your store account.

Try as a guest or sign in for your library and membership. When you want a multi AI chat alternative for an open-ended question, ask the AI research assistant once, compare AI answers, and keep one combined report. AI can make mistakes. Check important claims against the linked sources.
