How to choose without wasting money
1. Start with the task, not the tool
Write down the job you want gone: drafting quotes, chasing invoices, answering the same five questions. Then look for the tool that does that job inside software you already pay for. Most businesses already own something that can do it.
2. Prefer one tool that fits your stack
If you run on Google Workspace, Gemini is already there. If you run on Microsoft 365, Copilot is already there. Adding a third ecosystem usually costs more in time than it saves.
3. Stay on free tiers until a limit actually hurts
Free plans cover real work for a one or two person business. Upgrade when you hit a specific wall you can name, not because the comparison table looked better.
4. Test on a real job before you commit
Give the tool one genuine task from last week, with your real tone and your real customer. If the output needs a full rewrite, it is the wrong tool for that job.
