AI tools with the most product-market fit We asked my 1m+ newsletter subscribers “Which AI tool(s) would you be very disappointed to lose access to?” ChatGPT dominates. Half of respondents (50.2%) would be very disappointed to lose ChatGPT. Claude came in second, followed by Cursor, Gemini, and then Claude Code. It's interesting to see @meetgranola at #7, and @Lovable right after.
