Short answer: there is no single best free AI chatbot, because the three big free plans limit different things. ChatGPT's free plan offers unlimited everyday text chats but caps uploads, images, voice and research. Claude's free plan runs on a usage budget that resets on a rolling five-hour window, with no published message count. Gemini's free plan has "standard limits" that refresh every 5 hours up to a weekly limit. I checked each company's own pages on October 12, 2026.

Short answer: NotebookLM is now called Gemini Notebook in Google's help pages. The free plan allows up to 100 notebooks and 50 sources per notebook, with each source up to 500,000 words or 200MB. Everything else (chat, Audio Overviews, reports) now runs on a usage budget that refreshes every 5 hours until a weekly limit. Google doesn't publish daily counts, so older "50 chats a day" figures are no longer official.

Short answer: A Gemini "usage limit reached" message means you've used your allowance for the current window. Google says the limit refreshes every five hours until you hit a separate weekly limit, so the fix is to wait for the refresh time Gemini shows, use less per prompt, or upgrade.
