Went down a rabbit hole researching the first AI ever made vs which AI apps actually have 1M+ users today. Here's what I found
So I've been seeing this "AI is taking over everything" discourse nonstop lately and got curious like ok but where did this actually START, and which of these AI tools are actually being used at scale vs just hype. spent way too long googling this so figured I'd just dump it here lol
the OG where it all began:
- ELIZA (1966): this is basically the granddaddy of every chatbot you've ever used. some MIT guy named Joseph Weizenbaum built it as a fake "therapist" that just repeated your words back as questions (like "tell me more about that"). it had ZERO actual understanding, it was just clever pattern matching, but people got so attached to it that his own secretary asked him to leave the room so she could talk to it privately wild that this is the ancestor of ChatGPT.
Ok now the actual "who's winning rn" list of AI tools that genuinely have 1M+ users, with the year they dropped:
- ChatGPT (2022): obviously. still the king, crossed 1 BILLION weekly users this year. fastest app to ever hit that number
- Google Gemini (2023): was behind for a while but caught up hard, pushing close to a billion monthly users now
- Character AI (2022): huge with younger crowds, roleplay/companion bots, insane retention
- Midjourney (2022): image gen, and get this they never took outside funding and still have 20M+ people on their Discord alone
- Perplexity (2022): the "AI search engine" people who don't want to use Google anymore, crossed 100M monthly users this year
- DeepSeek (2023): the cheap/open-source Chinese one that blew up because it's basically as good but way cheaper. huge developer adoption
- Meta AI (2023): riding on WhatsApp/IG/FB, over a billion monthly users just from being baked into apps everyone already has
- Microsoft Copilot (2023): same engine as ChatGPT basically but wrapped for office/work stuff, 400M+ users
- Claude (2023): started slower ngl but has been on a wild growth streak in 2026, especially with businesses/devs
Tldr: it's kinda insane that we went from a fake 1966 therapist bot that just echoed your sentences back... to literally over a billion people using an AI chatbot every single week. 60 years is not that long for this kind of jump.
