App Store: "AI chatbot" search results (US)
The App Store's top results for the same search look very different. They're dominated by character and companion apps, not the big assistants:
| App | Developer | Rating | Ratings |
|---|---|---|---|
| Character AI | Character.AI | 4.27 | 560,739 |
| AI Chatbot – Nova | ScaleUp | 4.64 | 127,329 |
| Sakura | Sakura AI | 4.76 | 22,327 |
| AI Chatbot – Ask Me Anything | Evolly | 4.64 | 15,917 |
| EMOCHI World | Mesora | 4.66 | 12,858 |
| Soulplay | Studio Dopa | 4.64 | 12,356 |
What the numbers say
- The big three assistants have massive scale and high ratings. ChatGPT and Gemini alone account for about 85% of all the ratings in this list.
- Same app, different store reputation. Character AI is rated 2.25 on Google Play but 4.27 on the App Store. Always check both stores before drawing conclusions.
- Companion apps are the growth niche for smaller developers. PolyBuzz, Talkie and Emochi each have 10–50M+ installs, from studios most people have never heard of.
- Search position isn't popularity. On the App Store, ChatGPT and Gemini don't appear in the top results for the generic term "AI chatbot", which is a reminder that store search ranking depends on keywords, not just size.
