PRACTICAL GUIDE · CHOOSE BY USE CASE
Free AI writing tools: choose the editing job first
Proofreading an existing paragraph and generating a first draft are different jobs. Start with the part of writing you want help with, then compare the allowance and restrictions that apply to that activity.
Questions to settle before choosing
Are you drafting or revising?
Choose one representative piece of writing and specify the help you need. Use the product descriptions to shortlist options for that step.
What does the allowance measure?
Prompts, characters and words cannot be compared as if they were the same unit. Keep the provider’s wording and plan around your own workload.
How will you review the result?
Check factual statements, quotations and whether the wording preserves your meaning. A free-plan comparison does not assess the quality or originality of an individual output.
A selection to explore
An editorial selection, not a measured ranking. Access types and restrictions remain visible, including trials or paid access where relevant.
