| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | S-tier for solo + free. The best free option, hands down. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. |
