Free AI Writing Tools

Which AI writing, editing and content tools a startup can use for free today, how many words or rewrites the free plan covers, which features it keeps for paid plans, whether a card is needed and what the first paid plan costs, read from each tool's own page.

5writing assistants
4AI content generators

Free allowances read on each provider's own pages, all checked on or after . AI writing tools change their word caps and free plans often: confirm the terms on the tool's page before you rely on it.

AI writing tools you can use for free today include QuillBot (Paraphrasing up to 100 words a time), Rytr (10,000 characters a month, free forever), Grammarly (Spelling and grammar checks, free), Jasper (7-day free trial, all platform features), and Wordtune (10 rewrites and AI suggestions, unlimited grammar checks). Each of the 9 free plans below links to the tool's page that states it, with its main limit, where it works, whether a card is needed and what the first paid plan costs.

AI writing tools check grammar, rewrite sentences and draft copy for the site, the blog and the inbox. Most have a free plan or a free trial, and for an early team that is often enough.

The headline rarely tells you how far it goes. A free plan can cap the words per paraphrase, the rewrites per day or the characters per month, and keep full rewrites or tone controls for paid plans. Each tool below shows what is free, its main limit, whether a card is needed and what the first paid plan costs, quoted from the tool's own page with the date we read it.

Which tools we picked and the order they appear in are our editorial choices; the terms are the tools'. Some of these tools pay us a referral commission when someone signs up through our link: those links are labeled, and they play no part in which tools are listed or where.

Methodology

How this comparison is built

The list covers AI writing assistants and content generators a founder can use for free today without applying to a program. The order and the "best for" notes are our editorial reading of each tool's terms. Every term comes from the tool's own pricing or help page on the date shown, never from a third-party list; follow each link for the full conditions. A cap on words or credits, or modes kept for paid plans, can matter more than the headline, so the comparison quotes them wherever the tool states them. Some of these tools pay StartupPerks a referral commission, and their links are labeled as referral links; that decides neither whether nor where a tool appears, and no tool pays for a placement on this page.

StartupPerks is a comparison tool and is not endorsed by the programs it lists. It is a referral partner of some providers, and those links are labeled where they appear. AITraining.jobs and Founden are run by the same company as StartupPerks: their listings are free, ranked by the same rules as every other program, and labeled "Same owner as StartupPerks" wherever they appear. Values and eligibility are aggregated from each provider's public pages and can change or be incomplete. Always confirm the current terms and your eligibility on the provider's own page before applying.
