Jenni AI
Academic writing editor with autocomplete, citation insertion, PDF chat and AI-edit suggestions.
Academic & Student Tools from USD 12.00
The best free AI humanizers
Tools with a free tier large enough to form an opinion. Ranked by editorial level first, which means a reviewed tool outranks an unreviewed one even when the unreviewed one is more famous.
Read this before the list
Free means free of charge, not free of consequence: your text goes to the vendor either way, and free tiers are where retention policies are loosest.
