1. ChatGPT Free: best for outlines and first drafts

ChatGPT’s free plan runs on GPT-6 for text. Paste your essay question and ask for three possible arguments, an outline, or counterpoints to your thesis. It’s also good at explaining a reading you don’t understand. Don’t trust its citations without checking them; it can still invent sources. Our free chat AI guide covers its limits.

2. Claude Free: best for feedback on long work

Claude handles long documents well. Upload your draft and the marking rubric, then ask where your argument is weakest. The free plan includes Sonnet and Haiku, file uploads and up to 5 projects, with usage that resets every five hours. See is Claude AI free for the full breakdown.

3. Jenni AI: best free AI essay writer for citations

Jenni is built for academic writing. It suggests your next sentence as you type, lets you chat with uploaded PDFs, and formats references in more than 10,000 citation styles. The free plan includes 10 AI autocompletes a day, 10 PDF uploads, 3 AI edits, 5 AI chat messages and unlimited citations.

4. Grammarly Free: best for the final polish

Grammarly Free fixes spelling and grammar, shows your tone and includes 100 AI prompts for rewriting. Pro costs $12 a month and adds full-sentence rewrites, plagiarism checks and AI text detection, which is useful before you submit.

5. Gemini: best for research with Google tools

Gemini’s free tier is handy if your notes already live in Google Docs and Drive. Use it to summarize sources and compare viewpoints, then write the argument yourself.

How to write an essay with AI, the honest way

• Check the rules: some courses allow AI for brainstorming only; others ask you to disclose it.
• Outline with AI, decide yourself: pick the argument you can defend best.
• Write in your own voice: ask AI for feedback on each paragraph instead of having it write them.
• Verify every source: open each citation and confirm it says what you claim.
• Edit last: run Grammarly or Claude for clarity, then read the essay aloud.
