How to choose AI Writing tools

Two things separate these tools more than anything else. The first is the kind of writing each tool is built for. Sudowrite is built only for fiction. SEO Writing AI and Intelliwriter are built for search-optimized articles. Spell and Revise suit general documents and team editing. The second is cost before any work is done. Smodin, Spell, SEO Writing AI, Revise, and ProWritingAid all have a free plan. QuillBot, Sudowrite, and Intelliwriter are paid only, and ShortlyAI publishes no price at all.

  1. What kind of writing the tool is built for

    Fiction writers have one clear option: Sudowrite. It generates the next section of a story, expands scenes, and gives feedback on drafts. It does not handle business or academic writing. For Academic Writing, Smodin, Studybay AI Essay Writer, Spell, and QuillBot all cover that ground. QuillBot adds citation generation and a plagiarism checker. For SEO Content Creation, SEO Writing AI analyses competitor pages and can post directly to WordPress. Intelliwriter starts at $14.99 a month and focuses on content written to rank in search results. Spell and Revise both allow multiple people to edit the same document at the same time.

  2. Whether a free plan covers enough to start

    Ten tools here have a free plan, but none is completely free. Spell's free plan exists but limits how many AI messages can be sent per day. Revise's free plan caps daily AI use and requires a paid plan for higher limits. SEO Writing AI offers a free plan alongside a $29 a month Pro plan. ProWritingAid's free plan restricts word count and blocks access to chapter critique and manuscript analysis. Smodin's free plan is available but premium pricing requires contacting sales. Studybay AI Essay Writer charges from $3 per page for AI essay generation. QuillBot, Sudowrite, and Intelliwriter have no free plan at all.

  3. What the tool adds beyond generating text

    QuillBot includes a plagiarism checker and an AI detector alongside its rewriting tools, which matters for anyone submitting work that must be original. ProWritingAid goes further with more than 25 different writing reports, a chapter critique feature, and a tool that reads a manuscript the way a test reader would. Smodin claims over 98% accuracy in spotting AI-generated text and can rewrite content to remove those signals. Spell and Revise both keep a full revision history so earlier versions of a document can be recovered. Sudowrite and ShortlyAI focus on generation and brainstorming and do not offer plagiarism or AI detection.

Frequently asked questions

Which AI writing tools have a free plan?

Ten tools here have a free plan, including Smodin, Spell, SEO Writing AI, Revise, ProWritingAid, and Wordtune. None is completely free: each limits something, whether that is daily AI messages, word count, or access to advanced features. Wordtune's free plan is called Basic and costs $0 a month. QuillBot, Sudowrite, Intelliwriter, and ShortlyAI have no free plan.

Which tool is built for writing fiction with AI?

Sudowrite is the only tool here built solely for fiction. It writes the next 300 words of a story, expands scenes, helps with brainstorming, and gives feedback on drafts. Plans start at $10 a month for the Hobby and Student tier and go to $44 a month for the Max plan. Tools like ShortlyAI also support creative writing but are not limited to fiction and currently require joining a waitlist to access.

Which tools help with SEO content creation?

SEO Writing AI and Intelliwriter are the two tools here focused on search-optimized content. SEO Writing AI analyses competitor pages, handles keyword placement, generates articles in bulk, and posts them to WordPress automatically. Its Pro plan is $29 a month. Intelliwriter starts at $14.99 a month and writes content aimed at ranking in search results, with a $199.99 a month Premium plan for higher volume.

Which AI writing tools work for students and academic essays?

QuillBot, Smodin, Studybay AI Essay Writer, Spell, and Wordtune all cover academic writing. Studybay AI Essay Writer is the most focused: it generates essays, checks grammar and style, detects plagiarism, and assists with citations, charging from $3 per page. QuillBot adds citation generation and a plagiarism checker and costs $14.95 a month or $89.95 a year for an individual. Smodin and Spell both have free plans that cover some academic writing features.

Which tools let a team write and edit together?

Spell and Revise both support real-time editing by multiple people on the same document. Spell's Team Plan is $40 per user per month and includes full document editing with AI-powered drafting. Revise keeps a revision history and shows tracked changes so every AI edit can be reviewed or reversed. Both have free plans, though daily AI use is capped on each.

Do any AI writing tools publish no price at all?

ShortlyAI lists no price on its website and requires joining a waitlist for access. Smodin's premium pricing also requires contacting sales rather than showing a number. Intelliwriter does publish its prices: $14.99, $28.99, and $199.99 a month depending on the plan. QuillBot publishes its individual plan at $14.95 a month and team seats from $6.66 per seat per month when billed annually.
