Most 'free' AI writing tools are free trials disguised as free plans. After 7 days or 500 words you hit a paywall. The tools below are different — either permanently free with real usage limits, or free with no time restriction. Here's what's actually free in 2026, and what the genuine limitations are.
Copy.ai Free
Best free plan
4.0/5
2,000 words per month — the most generous permanently-free AI writing tier available. No credit card, no trial expiry. Access to all templates. Genuinely useful for occasional writers who don't need volume.
From $0 · Permanently free
ChatGPT Free
Most versatile
3.8/5
GPT-3.5 access at zero cost with no word limits. Less capable than GPT-4o (ChatGPT Plus) but handles most writing tasks competently. Requires more prompt engineering than template-based tools — better for users comfortable directing an AI through conversation.

Writesonic Free
10K words free
3.9/5
10,000 words per month free — the highest word count of any free tier. Access to article writer, templates, and Botsonic. Generous enough to evaluate the tool properly before committing to a paid plan.
