How to Choose
Start with the problem, not the tool. Identify the single highest-cost, highest-repetition task in your business. Then select the tool that directly addresses that specific task. Avoid the temptation to buy five tools simultaneously — tool sprawl creates complexity without proportional value.
Warning on tool sprawl: The average business in 2026 pays for 4-7 AI tools but actively uses 1-2 of them. One well-implemented AI tool beats five unused subscriptions. Nail one, then expand.
