AI writing tools are easy to compare badly. Generic prompts often make every product look similar, so test them on the documents your business actually creates.
Test the same jobs
Give ChatGPT, Claude and Gemini the same customer email, proposal outline and long document. Compare accuracy, editing effort and how well each tool follows your tone.
Human review still matters
Check names, numbers, claims and links before publishing. Use AI to accelerate a draft, not to remove accountability for the final text.
Keep sensitive information in mind
Before uploading client or company material, review the provider’s current privacy, retention and business-account settings.
