Review: Lex.page for Marketing Copywriters

As a B2B copywriter, I'm always on the lookout for new tools and technologies that can streamline my writing workflow and help me create more effective content for my clients. I’ve used tools like Jasper, Gemini, TextCortex, Claude, and even Perplexity. 

Lex.page stands out as one of the few tools that is closer to a word processor than it is a chatbot (sharing similarities with tools like Jenni.ai and Jasper.ai). I first heard about Lex from Shu Omi. In it, he posits Lex as a AI writing assistant that lives in your comment section, which was what got me to give it a try.  

What is Lex? 

Lex, as mentioned, is more of a word processor than it is a pure text generator. Yes, you can get it to generate the text for you, but that will create nothing but the same thing everyone else is saying.  Instead, the best way to use Lex is to follow what the tutorial says, which is: 

1. Create a new document
2. Copy paste all your research notes/text into the document
3. At the top or bottom of the document (I personally prefer bottom), do a quick stream of consciousness exercise about the type of document you want to create, your target audience, what you hope to achieve, etc. 
1. Yup, this is a more extreme version of my prompt process
2. What you’re doing here is giving Lex context of how to view your document. 
4. Once you’re done, then you can hit the “Ask Lex” button on the right sidebar (the first icon under your profile pic) and ask it for help. 

If you’re not sure what to write, the Lex team has already included some premade templates to get your brain juices flowing. And here’s the kicker.

Switching to other LLMs is easy  

Lex has actually integrated other LLMs into their AI settings, which you can change at any time. Just head into the Settings on the right sidebar again, and then you can see this pretty extensive list. I’m actually pretty impressed - when I started writing this review 3 days ago, they had already integrated Meta’s Llama 3.1 and Mistral’s latest models, both of which had launched just a day or so before.  

How does Lex work?

Lex works best if you are the person doing the actual writing, with it chiming in as a writing assistant to help when you get stuck. It feels like you’re rubberducking, researching, and writing all at the same time.

Lex.page keyboard shortcuts  

You know Lex was designed by people who interact with a computer mainly through keyboards by how easy it is to format a document using keyboard shortcuts. Some things you should know: 

• Markdown compatible format
  If you use Markdown a lot, then you’ll feel right at home here. And unlike Wordpress, you can also use your regular keyboard shortcuts like Ctrl + B to format text in the same document, no extra switching needed. Yes, Ctrl/CMD + S saves the document just like desktop word processors. 
• CTRL/CMD + K brings up more options
  If you want Lex to run checks on your document, continue writing for you, or even just to generate text, this combination will bring up the menu. 
• Stuck? Press + three times
  This will immediately get Lex to generate the next words for you in your paragraph. Goes on for quite a bit too. 

Is this process more involved than simply prompting another chatbot? You bet.

Will it be more rewarding? For me, yes, because this process preserves more of your writing style and voice while strengthening delivery and providing structure.  

Should Copywriters Use Lex?

Honestly, for one-off items such as SEO blogs, articles, and I suspect even ebooks, Lex might be a pretty good option to keep in your back pocket. However, this is reliant on the following: 

• Your research materials are primarily text, as it requires you to compile everything into a single document. 
• You are very familiar with your intended topic and talking points, and what you really need is just some assistance to help you actually write and restructure thoughts. 
• You are not looking to hand off the creation process to someone else - you’re looking to write more effectively, whatever that means in your process. 

If this sounds like you, then yes, I think you should give Lex a try. However, if you’re just looking for someone else to do the thinking for you, no, Lex (and honestly, most other GenAI tools) are not for you. 

Who else might benefit from Lex?

Stream of consciousness writers. If you are the kind to simply write and want to format your writing after, then I think Lex would be perfect for you. 

Is Lex Free? 

Lex currently has two tiers - free and pro. For the pro tier, you can opt to pay monthly (USD $18) or yearly (USD $145). The biggest difference is in the available LLM models available - certain models which cost more are locked behind the Pro tier (which is fair and understandable).

One thing to note is that Lex themselves have turned on the options (wherever possible) to NOT use your data for training AIs (see their FAQ). This is applicable for both the free and paid tiers.  For me, this makes subscribing to Lex appealing for such protection.  

Conclusion (aka the TL;DR) 

So, should you sign up for Lex? 

The short answer is, it depends. 

For me, there’s a lot of features I find appealing about Lex, but a lot of it is highly contextual and requires more testing. 

At the end of the day, Lex is more of a word processor with some thoughtful AI features built in. While you can throw in your knowledge and prompt Lex to do the writing for you, what you will get (regardless of the GenAI model you choose) will be quite generic and honestly not worth the time.

To utilise Lex fully, you the writer need to put in the work to get the results you want. But applied correctly, Lex can really take your writing to the next level, and in doing so, you will actually learn the craft, rather than outsourcing the lessons to a language seeking pattern.

Side note: I had an odd bug when I first signed up for Lex where it kept looping that same document, making it impossible for me to create a new document or do anything else. However, this was quickly fixed, though I didn’t realise it then because I was buried under work and so only came back to Lex after almost 3 weeks. Have you tried Lex.page? What did you think of it?
