Tools and models
The prompting skills you have learned work across every AI tool. But different tools have different strengths, and knowing which to reach for saves time.
Which tool for which task
Claude (by Anthropic) - strongest at long document analysis, careful reasoning, and nuanced writing. Handles up to 200 pages of text in a single conversation. Best choice when you need to upload a contract, financial report, or policy document and ask detailed questions about it.
ChatGPT (by OpenAI) - the most versatile general-purpose tool. Good at writing, brainstorming, coding, and image generation. The browsing feature lets it pull current information from the web. A solid default for everyday tasks.
Gemini (by Google) - integrates directly with Google Workspace. If your business runs on Gmail, Google Docs, and Google Sheets, Gemini can work with your existing documents without copy-pasting. Strong at multimodal tasks - combining text, images, and data.
Perplexity - built for research. Every answer includes source links so you can verify claims. Best choice when you need factual, referenced information rather than creative output.
Free vs paid
Every tool above offers a free tier. Free tiers are useful for learning and occasional tasks, but they come with limits - slower responses, older models, and usage caps.
Paid tiers (typically $25-35 CAD per month) give you access to the most capable models, faster responses, and higher usage limits. If you are using AI daily for business tasks, a paid subscription pays for itself quickly.
Business considerations
Data privacy - read the terms of service before uploading sensitive business data. Most paid tiers do not use your data for training. Free tiers sometimes do. If you handle client data, check the privacy policy or use the tool’s enterprise offering.
Terms of service - AI-generated content is generally yours to use commercially, but policies vary. Review the terms for your specific tool, especially if you are publishing content or using it in client deliverables.
Consistency - if your team uses AI, standardize on one tool. This makes it easier to share prompts, build templates, and train new team members.
Focus on the skill, not the tool
Tools change fast. New models launch every few months. The skill of writing clear, structured prompts does not change. A person who can write a great prompt for Claude can write a great prompt for ChatGPT, Gemini, or whatever launches next year.
Master one tool first. Learn its strengths and quirks. Build a library of prompts that work for your business. Then explore others when you have a specific need the first tool does not cover well.
