Kai's verdictA-tier. Best for teaching a kid to code in 2026.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
