FAQ
Q: How much should a small business spend on AI? A: Start at $50–80/mo (ChatGPT + 2 tools). Scale only after one tool clearly saves time.
Q: Will AI replace my team? A: No — it removes the tasks they resent. The team shifts to higher-value work.
Q: Is a custom chatbot worth it yet? A: Usually not for small teams. Start with off-the-shelf tools; build custom only if volume justifies it.
Verdict
The lean small-business stack is ChatGPT + Notion AI + Zapier + Otter. That quartet covers writing, memory, automation, and meetings — the four things that eat a small team’s day.
