  • Enterprise: contact sales, adds unlimited AI prompts, dedicated support and admin controls
Good fit for

Anyone who wants grammar, clarity and tone checks across email, documents and web forms.

Look elsewhere if

Users who mainly want long-form drafting from a prompt.

How it scored

  • Writing quality: 80/100. Its grammar, clarity and tone editing is the category reference, while AI drafting is serviceable rather than outstanding.
  • Works where you write: 100/100. Works in almost every place you type: browsers, email, Word and desktop apps.
  • Value: 70/100. Pro is $12 a month billed annually with 2,000 AI prompts, but $30 month to month.
  • Privacy & reliability: 70/100. Offers the standard data controls for this type of tool.
  • Expert & User Ratings: 70/100. Widely recommended by reviewers.

Our verdict

Grammarly ranks first because it works in nearly every place you type and its editing is widely recommended. Its AI drafting is serviceable rather than outstanding, so it suits polishing more than writing from scratch.

Pros
  • Works in browsers, email, Word and desktop apps
  • Strong grammar, clarity and tone suggestions
  • Useful free plan
Cons
  • Pro is much dearer billed monthly than annually
  • AI drafting less capable than leading chatbots
  • Best features need a paid plan

  • Pro is $12 a month only when billed annually; month to month it is $30.
  • The free plan has 100 AI prompts a month, while Pro gives 2,000.
  • Plagiarism and AI-text detection need Pro, and unlimited prompts and admin controls need an Enterprise quote.

Good fit for

All-round drafting, brainstorming and editing, including on a low budget.

Writers who want suggestions inside Word or Gmail rather than a separate app.

How it scored

  • Writing quality: 80/100. Strong drafting across many styles, with a Canvas editor for revisions.
  • Works where you write: 50/100. Works mainly in its own web and mobile apps, with little built-in help inside other tools.

  • Privacy & reliability: 50/100. Scored on outages in June 2025 and September 2026 and the addition of ads to the paid Go plan.
  • Expert & User Ratings: 80/100. The most widely recommended assistant overall.

Our verdict

ChatGPT ranks second as the most widely recommended assistant, with strong drafting and a capable free plan. It works mainly in its own apps, which limits its reach.

Pros
  • Strong drafting across many styles
  • Canvas editor for revisions
  • Capable free plan and $8 Go tier
Cons
  • Ads on Free and Go plans
  • Works mostly in its own apps
  • Has had outages
Things to know before you buy:
  • The Free plan and the $8-a-month Go plan (US price) both show ads, while Plus at $20 a month does not.
  • It works mainly in its own web and mobile apps, so there is little built-in help inside other writing tools.
  • Higher tiers above Plus are listed on the vendor's pricing page rather than fixed here.
  • Outage: June 10, 2025: a partial outage lasting most of a day. Sept 3, 2026: a roughly 34-minute outage blamed on a routing error.

  • Google Workspace business plans now cost more than before because Gemini is bundled in.
  • Price change: Jan 2025: Google Workspace business plans rose in price as Gemini was bundled in. Google AI Pro is $19.99 a month.
  • Outage: June 10, 2026: roughly 13 hours of disruption in two waves, blamed on a database performance issue.

How to Choose

Decide what you write most

Emails, reports, blog posts, fiction and marketing copy each suit different tools. General chatbots handle most jobs, editing tools polish what you have already written, and niche apps focus on one genre. Pick by your main use case rather than by feature count.

Check where the tool works

Some assistants live in their own app or browser tab, while others sit inside Gmail, Word, Docs or any text box through an extension. If you write mostly in one program, a tool that works there saves a lot of copying and pasting.

Try the free plan with your own text

Most tools here offer a free tier or trial. Give each one a real draft of yours and compare how natural the result sounds and how much editing it needs, because samples on marketing pages are rarely representative.

Compare annual and monthly prices

Several tools charge much less when billed annually than month to month. Work out which you would really use before committing to a year, and note that usage limits on cheaper plans can matter as much as price.

Look at usage limits

Chatbots cap how much you can send in a session or a week, and some editors cap daily rewrites. If you draft long documents or write every day, check the limits on the plan you plan to buy, not just the free tier.

Think about voice and privacy settings

If you want text that sounds like you, look for style matching, brand voice or the ability to upload samples. Also review each tool's data and training settings before pasting in confidential work.

Frequently Asked Questions

Which AI writing assistant is best for everyday emails and documents?

Tools that work inside the apps you already use are the easiest. Gemini fits Gmail and Google Docs, Microsoft Copilot fits Word and Outlook, and Grammarly works in most browsers and desktop apps. ChatGPT and Claude are strong drafters but mainly live in their own apps.

Can I use an AI writing assistant for free?

Yes, most have a free tier. Gemini, ChatGPT, Claude, Copilot, Grammarly, QuillBot, Wordtune and Rytr all offer free plans with limits. Jasper offers a 7-day trial rather than a free plan, and Sudowrite offers a free trial with no credit card.

What is the difference between a chatbot and an editing tool?

A chatbot such as ChatGPT or Claude can draft, brainstorm and rewrite from a prompt. An editing tool such as Grammarly, QuillBot or Wordtune works on text you have already written, suggesting corrections, rephrasings and tone changes.

Which tool is best for fiction?

Sudowrite is built around stories, with tools for brainstorming, outlining and expanding scenes. General chatbots such as Claude and ChatGPT are also widely used for creative drafting and can handle other writing too.

Should I edit AI-generated text before using it?

Yes. AI drafts can be generic, contain mistakes or miss your voice, so read and revise them before publishing or sending. Editing tools like Grammarly can help with a final polish.

How We Evaluated

Every Flickthru ranking follows the same five-step process, applied the same way to every product on the page.

  1. Market scan: We gathered the 28 platforms recommended across current expert reviews, buyer guides and verified-user ratings, then shortlisted the 10 that best fit this category and offer their own built-in AI.
  2. Evidence gathering: For each shortlisted product we collected features, plans and current pricing from the vendor, alongside the strengths and weaknesses reported in recent expert reviews.
  3. Risk checks: We checked every product for recent price changes and service reliability. Anything relevant is summarised in the product’s Detailed Analysis and reflected in its score.
  4. Scoring: Each product is scored against the five criteria in our Evaluation Methodology using the same rules for every product, and the Flickthru Score out of 100 combines them. Writing quality, the main job these tools do, counts most. Value is judged on what the paid plans deliver for their price. Each product’s Detailed Analysis explains how it scored on every criterion.
  5. Editorial independence: Rankings are decided by Flickthru’s editorial process alone. Placement cannot be bought.

This ranking was last updated in September 2026. This page was researched and drafted with the help of Claude, an AI assistant made by Anthropic, which is one of the companies ranked here. We applied the same criteria to every assistant.
