The available evidence falls into three different buckets. Similarweb’s AI Chatbots and Tools page is a website or domain category ranking, and the visible excerpt lists domains including chatgpt.com, grok.com and openai.com. First Page Sage’s April 2026 material tracks market-share trends for generative AI chatbots and names products such as ChatGPT, Google Gemini, Perplexity and ClaudeAI. Revoyant, ZDNET and iTitans are 2026 AI chatbot reviews or recommendation lists that include tools such as ChatGPT, Claude, Gemini, Copilot, Perplexity, Grok, Meta AI, DeepSeek, Poe and Character AI.
Those are useful signals, but they are not the same ranking. A website-traffic category list is not an App Store or Google Play chart. A general category ranking is also not automatically a Taiwan-only ranking. Mixing those sources into one table can make the result look more precise than the evidence allows.
In the visible Similarweb excerpt for the AI Chatbots and Tools category, chatgpt.com is ranked No. 1, grok.com No. 4 and openai.com No. 6. The same excerpt also shows kimi.com at No. 12, base44.com at No. 24 and you.com at No. 42.
That supports three cautious conclusions:
If the goal is to build a practical list of mainstream AI chat tools to compare, the public evidence can be combined more carefully: website-ranking signals, 2026 market-share tracking and 2026 review lists can all help identify likely candidates. The order below is a comparison priority, not a Taiwan-specific website-traffic ranking, search ranking or app-store ranking.
| Reference order | AI chat tool | Public signal supporting inclusion |
|---|---|---|
| 1 | ChatGPT | The visible Similarweb excerpt ranks chatgpt.com No. 1 in the AI Chatbots and Tools category; Revoyant lists ChatGPT as a major 2026 AI chatbot; First Page Sage includes ChatGPT in its April 2026 generative AI chatbot market-share tracking. |
| 2 | Google Gemini | First Page Sage includes Google Gemini in its April 2026 generative AI chatbot market-share tracking; Revoyant’s 2026 list also includes Google Gemini. |
| 3 | Claude | First Page Sage includes ClaudeAI in its April 2026 generative AI chatbot market-share tracking; Revoyant’s 2026 list also includes Claude. |
| 4 | Perplexity AI | First Page Sage includes Perplexity in its April 2026 generative AI chatbot market-share tracking; Revoyant’s 2026 list also includes Perplexity AI. |
| 5 | Microsoft Copilot | Revoyant’s 2026 list includes Microsoft Copilot; ZDNET’s 2026 review explicitly says it tested ChatGPT, Copilot and other tools. |
| 6 | Grok | The visible Similarweb excerpt ranks grok.com No. 4 in the AI Chatbots and Tools category; ZDNET’s 2026 review excerpt also mentions testing involving Grok. |
| 7 | Meta AI | Revoyant includes Meta AI in its 2026 list; iTitans’ 2026 roundup of ChatGPT-like apps also mentions Meta AI. |
| 8 | DeepSeek | Revoyant discusses DeepSeek in its 2026 open-source AI chatbot category. |
| 9 | Poe | iTitans’ 2026 roundup of ChatGPT-like apps mentions Poe. |
| 10 | Character AI | iTitans’ 2026 roundup discusses Character AI and describes its conversations as leaning toward personality-style interaction. |
Under a strict “publicly visible website-ranking data only” standard, the clearest chatbot-related entries in the provided evidence are chatgpt.com at No. 1 and grok.com at No. 4. openai.com also appears at No. 6, but it is better treated as an OpenAI or ChatGPT-related domain rather than a separate chatbot app slot when the goal is to compare products.
The same Similarweb excerpt lists kimi.com at No. 12, base44.com at No. 24 and you.com at No. 42. Those domains may be worth monitoring, but they are not top-ten entries in the visible excerpt.
To produce a strict “Taiwan 2026 top ten AI chat apps by website ranking,” four things would need to be fixed in advance:
The cleanest conclusion is therefore limited but useful: public sources are enough to identify major AI chat tools worth comparing in 2026, but not enough to claim that they are Taiwan’s verified top ten by website ranking. A true Taiwan list would require a complete dataset filtered to Taiwan, measured over the same period, ranked by the same metric and cleaned for product-domain duplicates.
