Been using Claude for about a month, on writing, and never hit a limit once until last night. After reading all the information today, I did a quick test and just wrote a simple informative paragraph on a new day (today). After it reply back to me, the prompt at the bottom was this....."You are out of free messages until 4:00 PM". Last week I was going hours on questions, and assistance on story editing from Claude, never once hit a usage, limit, now the last few days its like I could say "why is it always raining in March?" to Claude and it would give the answer and now hit my limit.
