About AI vs Guide

AI vs Guide is an independent website that compares consumer AI assistants such as ChatGPT, Claude, Gemini, Perplexity, DeepSeek, Microsoft Copilot, Grok and Mistral Le Chat. We built it because most “best AI” pages are opinion lists with no dates and no sources. Prices and plan limits change every few weeks, so an undated comparison is often wrong.

What makes this site different

• Structured data, not just prose. Every assistant has a data file with its plans, prices, models and features. Comparison tables are generated from those files, so the same fact is identical on every page.
• Every fact has a source and a date. Each price or feature links to the vendor’s official page and carries the date we checked it. If we cannot confirm something, we show “Not verified” instead of guessing.
• No fake tests. We do not publish invented benchmarks, personal anecdotes or testimonials. When hands-on testing is needed, we say so and add it only once it has actually been done.

Independence

AI vs Guide is not affiliated with, endorsed by or sponsored by OpenAI, Anthropic, Google, Microsoft, xAI, Mistral AI, Perplexity, DeepSeek, Meta, Quora, Alibaba, Moonshot AI or any other company we cover. Product names are used only to identify the products being compared. No vendor pays for placement or rankings. The site may display advertising in the future; ads will never influence verdicts and will be clearly labeled.
