Trend 1: Free Is the New Premium

80% of these tools are completely free.

What this means:

• Barriers to entry are gone (anyone can create professional content)
• Competition shifts to strategy (tools are commoditized; execution matters)

For marketers: You can now test more, learn faster, and scale smarter—but you need analytics (like Adfynx) to make sense of all that data.

15 out of 26 tools are Chinese (ByteDance, Alibaba, Tencent, Baidu).

• China is winning the AI race in consumer applications

• Global competition is intensifying (OpenAI, Google, and Chinese giants are all pushing boundaries)

For marketers: If you're targeting Chinese markets, Chinese tools are essential.

Trend 3: Specialization Is Dead, Integration Is King

Most tools now handle multiple modalities (text, images, video, data).

What this means:

• Single-purpose tools are being replaced by all-in-one platforms
• Workflows become integrated (no more switching between 10 apps)
• Context is preserved (AI remembers your conversation across tasks)

For marketers: Your AI stack should integrate seamlessly—create content with free tools, analyze with Adfynx, iterate based on data.

• ✅ Stay curious (new tools launch weekly—stay updated)

The tools exist. The strategies are proven.
