1. Which AI tools do businesses really need in 2026?

Market analysis 2026: 78% of DACH businesses use at least one AI tool in production (Bitkom, March 2026). But only 31% measure ROI systematically. Reason: most start with the wrong tool.

Three demand clusters dominate 2026 search behavior:

• Generative assistants ("ai tools", "ai apps") — text, images, code
• Specialized apps ("free ai", "ai software") — focused tools for audio, video, translation
• Enterprise platforms ("ai solutions consulting") — GDPR-compliant rollout with data integration

So the answer to "which AI to use?" depends on which cluster fits your use case. We cover all three.
