Frequently Asked Questions
Are free AI tools good enough for business use?
For many tasks, yes. Free tiers of ChatGPT, Grammarly, and Canva AI handle basic business needs well. However, for professional or high-volume use, paid tiers offer better quality, more features, and priority support. The best approach is often to start free and upgrade as your needs grow.
Which AI chatbot is best: ChatGPT, Claude, or Gemini?
Each has strengths. ChatGPT (GPT-4) is the most versatile and widely integrated. Claude excels at nuanced analysis, long documents, and coding. Gemini integrates best with Google Workspace. For most business users, try all three free tiers and see which fits your workflow best.
Are AI tools safe for confidential business data?
It depends on the tool and plan. Many free tiers use your data for training. Business/Enterprise plans typically offer data privacy guarantees. For confidential data, look for SOC 2 compliance, data processing agreements, and options to opt out of training. When in doubt, anonymise sensitive information.
How do AI tools compare to hiring staff?
AI tools excel at repetitive, high-volume tasks like answering FAQs, scheduling, and data entry. They work 24/7 and scale instantly. However, they cannot replace human judgment, relationship-building, or creative strategy. The best results come from AI handling routine work while humans focus on high-value activities.
What AI tools should a small business start with?
Start with: (1) ChatGPT or Claude for writing, research, and brainstorming, (2) Grammarly for professional communication, (3) Canva AI for quick design work, and (4) Zapier or Make for basic automation. These cover most small business needs and all have generous free tiers.
Can I build a custom AI chatbot for my business?
Yes. Options range from no-code platforms (like Chatfuel or ManyChat) to custom-built solutions. For a chatbot trained on your specific products, services, and FAQs—one that integrates with your website and CRM—a custom solution typically delivers better results. That's exactly what we build at Hand On Web.
How quickly is AI technology changing?
Very quickly. Major updates happen monthly. Tools that were cutting-edge six months ago may be surpassed by new options. We recommend checking this guide periodically (we update it regularly) and following announcements from OpenAI, Anthropic, and Google for major changes.
Do I need technical skills to use AI tools?
Most modern AI tools are designed for non-technical users. Chatbots like ChatGPT and Claude work through simple conversation. Design tools like Canva AI use intuitive interfaces. Automation tools like Zapier are visual and no-code. Technical skills only become necessary for custom integrations or self-hosted solutions.
