Comparison

Best Lex alternatives

Lex vs. Google Docs + ChatGPT: Lex integrates the AI directly into the writing workflow, creating a seamless experience. Pick Lex if you value a focused, minimalist environment and want to switch between the best AI models (like Claude and GPT-4) without leaving your document. Choose the Google Docs + ChatGPT combo if you need the full G-Suite ecosystem (Sheets, Slides) and are comfortable with the context-switching of copying and pasting between your document and a separate AI chat interface.

You need an all-in-one office suite with spreadsheets and presentations (e.g., Google Workspace).
Your workflow heavily relies on a mature 'Track Changes' feature, which is not yet available in Lex.
You require deep integration with a specific project management or CRM system.

Questions & Answers

Frequently asked questions

Is Lex secure and private for handling confidential business documents?

+
Yes. Lex states that all data is privately and securely hosted, with strict internal access policies. Crucially, your writing is not used to train AI models, as they leverage enterprise APIs with enhanced privacy protections.

Can I collaborate with my executive or team members using Lex?

+
Yes, collaboration is a core feature. You can share a link with anyone to collaborate on a document in real-time for free. For teams with heavy usage, a 'Lex Teams' add-on is available to organize work in shared folders.

What's the main benefit of upgrading to Lex Pro for an assistant?

+
The primary benefit of Lex Pro is access to the highest quality AI assistance through premium models like GPT-4.1 and Claude 4 Opus. This results in more intelligent and nuanced suggestions for your writing, along with priority support and early access to new features.

Does Lex work on mobile devices?

+
Yes, Lex provides a mobile web version that allows you and your collaborators to view and edit documents on the go, without needing to download a native application.

Can Lex replace Google Docs or Word for an EA's daily tasks?

+
For writing-centric tasks, yes. Lex is designed as a superior, focused writing experience. However, it does not include the other components of an office suite, such as spreadsheets or presentation software.

Is my writing used to train the AI?

+
No. Lex explicitly states that it uses enterprise APIs from partners like OpenAI and Anthropic, which prevents your data from being used for training. They commit to informing users for opt-out if this policy ever changes.
