Lex review: a free plan and $18 a month, checked in June
Lex is a writing app with AI in it rather than an AI tool with a text box, and that is the whole reason to choose it. Our last check, on 11 June 2026, recorded a free plan with limited AI writes and Pro at $18 a month. That evidence is four months old and we have not re-verified it since.
The short answer
Buy Lex Buy Lex Pro if you write long-form prose most days and want feedback inside the document rather than in a chat window. Pro was $18 a month when we checked lex.page on 11 June 2026, which is $216 across a year, and that figure is four months old now.
Skip it if you need marketing templates, bulk generation or SEO scoring, because Lex has none of them and is not trying to. Skip Pro specifically if you write weekly rather than daily: the free plan carried limited AI writes on our June check and may be enough.
Where Lex fits
Lex fits the person writing essays, newsletters, chapters or long blog posts who wants the AI to behave like an editor reading over their shoulder. The interface is a clean page, the suggestions appear as comments in the margin, and nothing about it resembles a marketing dashboard. That is the specific job it does better than the template tools.
The product is deliberately small, and the pricing reflects that. Our 11 June 2026 check of lex.page recorded two plans: a free tier with limited AI writes, and Pro at $18 a month with unlimited AI writes, autocomplete and AI comments. There is no seat ladder and no usage meter beyond the free limit.
Pro at $18 a month is $216 across a year on that June figure. Our check did not record an annual rate: the page pointed to lex.page for annual billing options rather than naming one, so assume monthly billing until you have read the current page yourself.
The free plan is the trial, and there is no time-limited trial behind it. Our June snapshot records limited AI generations on free with no expiry attached, which means the honest way to evaluate Lex is to write something real on the free tier and notice when you hit the limit.
The thing you are paying for is restraint. Lex suggests and comments and will not rewrite your text for you, which is the right behaviour for a manuscript and the wrong behaviour for someone who wants fifty social captions by lunchtime. Know which of those you are before you subscribe.
Against the category Lex is the cheapest paid plan of the long-form tools and the narrowest. Rytr was $7.50 a month on Unlimited with a free tier, verified 6 October 2026, and is cheaper but built around short-form templates. Notion AI was $10 per member a month on Plus, verified 1 October 2026, and puts writing inside a workspace. Jasper was $69 a month on Pro, verified 6 October 2026, and is a marketing tool rather than a writing one.
The pricing on this page was last verified on 11 June 2026 and is the oldest evidence we hold for this product. Four months is long enough for a plan to be renamed, a free limit to tighten or an annual option to appear, and those sibling prices above are from October, so this comparison is not strictly like for like. Read lex.page before you buy. The AI writing tools category holds the alternatives.
Lex pricing
Lex is a freemium subscription with a flat monthly rate for Pro and no per-word charges. The figures below come from our check of lex.page on 11 June 2026 and have not been re-verified since, so confirm them before you pay anything.
| Plan | Price | What it adds |
|---|---|---|
| Free | $0/mo | Limited AI writes. No time limit recorded on our June check |
| Pro | $18/mo | $216 a year. Unlimited AI writes, autocomplete and AI comments |
There are only two plans, so the decision is small. Four things settle it:
- Which plan you need. Free with limited AI writes, or Pro at $18 a month on our 11 June 2026 check, with nothing in between.
- How often you write. Pro buys unlimited AI writes, so the value is in daily use rather than in the volume of words produced on any one day.
- Whether you need the premium models. Our June snapshot records model access as part of Pro without naming the models, so read the current list off lex.page rather than trusting this page.
- Billing period, which our check did not record. Lex's June 2026 page pointed to lex.page for annual options instead of publishing a rate, so budget for monthly billing.
Lex pricing against the AI writing tools
Lex is at the cheap end of the category and the narrow end of it. Rytr is $7.50 a month on Unlimited with a free tier, verified 6 October 2026, and undercuts Lex while doing a different job. Notion AI is $10 per member a month on Plus, verified 1 October 2026, which is the closest thing to a direct comparison if your writing already lives in a workspace. Jasper is $69 a month on Pro, verified 6 October 2026. Note that all three of those dates are more recent than Lex's own, so the gaps may have moved.
Lex billing terms worth knowing
The free plan does the work a trial would do elsewhere, which is the one thing to understand before paying.
- Free plan
- $0 a month with limited AI writes, as recorded on 11 June 2026.
- Pro
- $18 per month, $216 across a year, on the 11 June 2026 check.
- Annual billing
- Not recorded. Lex's June page pointed to lex.page for annual options.
- Trial
- No time-limited trial recorded. The free plan is the trial.
- Per-word charges
- None recorded. Pro is a flat monthly rate.
- Seats
- No seat ladder recorded on our June check, despite collaboration being built in.
- Check date
- 11 June 2026, against lex.page. Four months old and not re-verified.
The figures on this page are four months old and are given with their date for exactly that reason. If Lex's current page differs, the page is right and this is out of date. Our 11 June 2026 snapshot records no annual rate, so this page states none rather than estimating one, and our creator tool cost calculators will total a writing stack once you have today's numbers.
What Lex gives up
There are no marketing templates. Ad copy, product descriptions and subject lines are not what Lex is for, so a creator who also needs those ends up with two subscriptions rather than one.
There is no SEO capability whatsoever. No SERP analysis, no topic scoring, no keyword data, which means a search-led writer runs Frase at $49 a month on Starter, verified 1 October 2026, next to it.
Export and formatting are limited. Writing in Lex and publishing elsewhere means a conversion step, and anyone who needs precise layout control will be moving the text into another editor before it ships.
The AI will not edit your text, only suggest. That restraint is the point of the product and it is also slower than a tool that rewrites a paragraph on request, and some writers will find it precious rather than respectful.
It is a small team with limited support. A product this focused depends on a few people continuing to work on it, which is a risk you accept rather than one you can price.
Our pricing evidence is from 11 June 2026, which is the weakest part of this page. Four months is long enough for the free allowance to tighten or the Pro rate to move, and we would rather say so than present a stale figure as current.
Bulk work is impossible by design. If your job is fifty pieces a month, Lex will slow you down, and Copy.ai at $29 a month on Chat, verified 6 October 2026, is shaped for that instead.
How Lex compares
The three tools below are the ones weighed against Lex, and the axis is long-form writing against generation at volume. Prices are each vendor's published rates with the date we checked them, and Lex's own date is four months older than the rest, so read the table with that in mind. The wider field sits in the AI writing tools category.
| Tool | Best for | Price | Where it breaks |
|---|---|---|---|
| Lex | Long-form prose with editorial feedback in the margin | Free, $18/mo Pro (June 2026) | No templates, no SEO, limited export |
| Rytr | Cheap short-form writing across many formats | Free, $7.50/mo Unlimited | Template-led, not built for a manuscript |
| Notion AI | Writing inside a workspace you already pay for | Free, $10/member/mo Plus | A workspace first and a writing tool second |
| Jasper | On-brand marketing copy across a team | $69/mo Pro ($59 annually) | Marketing copy rather than long-form prose |
What to test on the Lex free plan
The free plan carried limited AI writes with no time limit on our 11 June 2026 check, and that is the oldest evidence on this page. Confirm the current allowance first, because it is the figure everything else here depends on.
- Check the current free allowance and the Pro rate on lex.page. Our figures are from June 2026 and this is the one step you should not take on trust.
- Draft something you were going to write anyway, at its real length. A thousand words of your own work tells you more than any prompt experiment.
- Use the AI comments as an editor rather than as a writer. If the feedback makes you change a paragraph, the product is working as intended.
- Notice exactly when you hit the free AI limit. That moment is the whole upgrade decision, and it arrives sooner for daily writers than for weekly ones.
- Test the export route you will rely on. Limited formatting is a known constraint and it matters more if your work ships as a newsletter or a layout than as plain text.
- Try collaborating with one other person before relying on it. Our June snapshot records real-time collaboration as built in and records no seat pricing, so confirm how a second writer is billed.
- Set a year of Pro at $216 against Rytr at $7.50 a month, verified 6 October 2026, and Notion AI at $10 per member a month, verified 1 October 2026. The cost calculators will total the stack once you have Lex's current rate.
Lex questions buyers ask
How much does Lex cost per month?
Lex has a free plan with a monthly allowance of AI checks, and the Pro plan was $18 a month when checked on 11 June 2026. Our record does not contain an annual rate for Pro, so confirm that on lex.page rather than deriving one. Pro includes unlimited AI checks, premium models, early access to features and priority support. The pricing evidence is four months old.
Does Lex have a free plan?
Yes. Lex's free plan includes 30 AI checks per month, access to GPT-3.5, Mistral, Mixtral, and Llama 3 models, plus full document editing and collaboration features. It is enough for occasional writing with AI assistance but may feel limiting for daily writers who rely heavily on AI feedback.
Who is Lex best for?
Lex is built for writers who want AI assistance in a clean, focused editor: bloggers, newsletter authors, essayists, and book writers. It is not designed for marketers who need templates, SEO features, or bulk content generation. If you value the writing experience over output volume, Lex is a strong fit.
Lex vs Jasper: which is better?
Different tools for different needs. Lex is a distraction-free writing tool with inline AI feedback, best for long-form content. Jasper is a marketing-focused AI platform with templates, brand voice, and team features, best for marketing teams producing varied content types. Lex costs $18/month; Jasper starts at $69/month per seat. Choose Lex for writing; choose Jasper for marketing.
What AI models does Lex use?
The free plan includes GPT-3.5, Mistral 7B, Mixtral 8x22b, Llama 3 70b, Claude Instant, and Claude Haiku. The Pro plan adds GPT-4, GPT-4 Turbo, GPT-4o, Claude 2.0, Claude 2.1, Claude 3 Sonnet, and Claude 3 Opus. You can switch between models depending on your task.
Is Lex good for blog writing?
Yes: blog writing is one of Lex's strongest use cases. The distraction-free editor keeps you focused, the AI feedback helps with structure and clarity, and the title generation feature saves time on headlines. The main gap is that Lex has no SEO tools, so you will need a separate tool like Surfer or Frase for keyword optimization.
Can I export documents from Lex?
Lex supports basic document export, though formatting options are more limited than Google Docs or Notion. For most blog and newsletter workflows, you can copy the content directly into your publishing platform. If you need rich formatting, tables, or complex layouts, you will want to finalize the document in another tool.
Can teams collaborate in Lex?
Yes. Lex supports real-time collaborative editing similar to Google Docs. Multiple users can edit the same document, leave comments, and see changes live. However, there are no workspace management features, role-based permissions, or team billing options. It works for small teams but not for large content operations.
Is Lex worth $18 per month?
If you write daily and value a clean, focused editor with strong AI feedback, $18/month is fair. Especially since it includes unlimited AI checks with no word limits. If you write occasionally or need marketing-specific features, the free plan may be sufficient, or a tool like Copy.ai at $29/month might give you more for a similar price. Writesonic covers more ground still, but starts at $99/month.
Can I cancel Lex anytime?
Yes. Lex offers a month-to-month Pro plan with no long-term commitment. You can cancel anytime and keep access through the end of your billing period. The annual plan requires a 12-month commitment but comes with a money-back guarantee if you cancel within the first month.
