Best Free AI Email Writers: What You Get Without Paying
The best free AI email writers right now are the general assistants (ChatGPT, Claude, Gemini), built-in options like Gmail's AI help where available, Grammarly's free tier for editing, and Letter Moth's free plan of 10 drafts a day. Free tiers change often, so check limits before you rely on one.
This roundup explains what each free option is actually good for, since the real difference is workflow and limits, not just price. We build Letter Moth and say so, and we point out where the free tiers of other tools suit you better.
| Option | Free access | Best for | Draft lands in your email box |
|---|---|---|---|
| ChatGPT / Claude / Gemini | Free tiers, limits vary (check) | Flexible drafting and rewrites | No, you copy it over |
| Gmail built-in AI | Check availability for your account | Quick drafts in Gmail | Yes, in Gmail |
| Grammarly | Free tier (check what it includes) | Editing and clarity | Works where you type |
| Letter Moth | 10 drafts a day, 3 saved prompts, no card | Drafts from the page, limit-aware | Yes, inserted into the box |
| Jasper / Copy.ai | Check for a current free plan or trial | Marketing copy at volume | No |
What does free actually get you?
Free tiers usually trade something: a daily cap, fewer features, slower access to the newest models or a limited context window. That is fine for occasional emails, but worth knowing if you write many.
Look at four things: the daily or monthly limit, whether the draft lands in your email box or in a separate window, whether you need to paste context, and whether a card is required to start.
ChatGPT, Claude and Gemini free tiers
The big assistants all offer free access with usage limits that vary and change, so check each provider's site. For email, they are excellent: paste a rough idea and ask for a short, polite version in your tone, or ask for three subject line options. You supply the context each time, and copy the result across yourself.
- Strengths: very flexible, good at rewriting and brainstorming
- Trade-offs: copy and paste, usage caps, you manage voice and length
Gmail's built-in help: free where it is offered
Gmail has built-in AI writing help in some accounts and plans. It is convenient because it is right in the compose window. Check whether it is available to you and what limits apply, since availability depends on your account and region.
Grammarly's free tier: editing rather than drafting
Grammarly has a free tier that catches grammar and spelling and suggests clarity improvements across sites. It is a polish tool more than a writer, and many people pair it with a drafting tool. Check what the free tier includes today, since features move between tiers.
Our comparison Letter Moth vs Grammarly explains how the two differ.
Letter Moth's free plan: 10 drafts a day, no card
Letter Moth is a Chrome extension (also Edge, Brave and Opera, not Firefox or Safari). The free plan gives you 10 drafts a day and 3 saved prompts, and you do not need a card. You sign in with Google, write a profile once, and click the toolbar button on a profile or page. You review the context, untick anything you like, choose a tone and it inserts the draft into the email box, trimmed to the character limit. It never sends.
If you hit the daily cap, Pro is unlimited and prepaid: INR 299 for 30 days or INR 2,499 for a year, by UPI, card or net banking, never auto-renewing, with a 7-day refund on the first Pro purchase. See the cold email writer or the pricing section.
What it does not do: no sending, no email finding, no sequences, no CRM, and it does not work in Firefox or Safari.
Free trials of Jasper and Copy.ai
Jasper and Copy.ai are marketing copy platforms. Check their sites to see whether they offer a free plan or only a trial right now. They are aimed at teams producing lots of copy, which is more than most people need for personal emails.
Which free option should I start with?
If you write a few emails a week and enjoy chatting through ideas, start with a chatbot. If you want drafts in the box with fewer steps, add an extension. If you live in Gmail and keep things simple, try its built-in help if you have it. You do not have to choose only one.
Free tools still need your judgment. Read every draft and make sure the facts and tone are yours. Our guide to how to write a cold email that gets replies is a good checklist.
Whichever free tool you pick, build a few habits that make drafts better. Give the tool one clear goal for the email, one fact about the recipient and one specific ask. Keep the email under about 120 words. Read it aloud and cut anything you would not say in person.
Products change often. Treat this page as a starting point and check each tool's own site for current features, limits and pricing before you decide.
