Question 1

How do I compare AI answers side by side?

Accepted Answer

Blend's Compare mode sends one question to several AIs at once and puts their answers side by side, so you can see where they agree and where they differ. The points where two models disagree are almost always where the wrong answer is.

Question 2

How do I cross-check an AI answer?

Accepted Answer

Blend's Cross-check mode hands one AI's answer to a different AI and asks it to find factual and logical errors. Using a second model matters — asking the same model to check itself shares the same blind spots.

Question 3

What is a multi-AI app?

Accepted Answer

A multi-AI app lets you use several AI models from one place instead of subscribing to each separately. Blend is a multi-AI workspace: one question, multiple AIs, better answers — with Claude, GPT, Gemini, DeepSeek, Groq, Mistral and Cohere in one screen.

Question 4

What is Blend?

Accepted Answer

Blend is a unified AI app that automatically matches the best AI to each question. You can use Claude, GPT, Gemini, DeepSeek, Groq, Mistral and Cohere from one screen.

Question 5

Can I use Claude and GPT without my own API keys?

Accepted Answer

Yes. With a Blend subscription (from $9/month) you can use 7 AI providers key-free. You can also register your own API keys (BYOKey advanced mode) for unlimited use.

Question 6

Is there a free version of Blend?

Accepted Answer

Yes. Blend offers a free daily trial (Gemini, 60 messages per day) with no API key required.

Question 7

How much does Blend cost?

Accepted Answer

A free daily trial, Pro at $9/month, or Smarter at $43.20 for 6 months (20% off) or $54 for 1 year (50% off). Optional prepaid credit packs ($5, $10, $20) are also available.
