I have been using Claude AI (and some ChatGPT and some Perplexity). I even subscribed to the $20 monthly plan for Claude. Recently I exceeded my allowed time (or number of entries or some limit) and was cut off and told that I could return in 5 hours. Since then I've been unable to use it. I've tried shutting it down and restarting and clearing cache in my browser.
Claude's tetrad color harmony recommendation focuses on a rectangular arrangement, differing from the square tetrad suggestions provided by other AI systems like DeepSeek and ChatGPT. This unique approach aims to accommodate color deficiencies while still prioritizing aesthetic compatibility.
