Your First Use

Here’s your first concrete interaction with Lex. Open a new document and try these steps:

1. Create a new document – Click the “+” icon or “New doc” on the dashboard.
2. Type a prompt – For example, type:

Write a short email to my team announcing a new feature launch

1. Press Enter – Lex will immediately generate a draft below your prompt. The AI works inline, so you’ll see the text appear as you write or after you press Enter.

What happens? – Lex’s AI reads your prompt and produces a complete, context-aware response. You can then edit it, ask for a rewrite, or expand on any section. Expected output (example):

Subject: Exciting New Feature Launch!

   Hi Team,

   I’m thrilled to announce that our new [Feature Name] is now live. This update will help our users [key benefit].

   Please check it out and let me know if you have any questions.

   Best,
   [Your Name]

You can also highlight any text and use the AI toolbar (pencil icon) to rewrite, shorten, or expand that section.

Common Use Cases

1. Drafting a blog post outline

- Type: Outline a blog post about remote work productivity tips

- Lex returns a structured outline with headings and bullet points. You can then expand each section by clicking “Write more.”

2. Rewriting a paragraph for clarity or tone

- Highlight a dense sentence, click the AI icon, and choose “Simplify” or “Make more professional.”

- Example: Input The implementation of the new protocol will facilitate an increase in operational efficiency. → Output The new protocol will help us work more efficiently.

3. Brainstorming ideas for a campaign

- Type: Give me 5 catchy taglines for a sustainable clothing brand

- Lex generates a list you can refine. Use the “Generate more” option to get additional ideas.

Tips & Best Practices

• Stay within free tier limits – Lex’s free plan includes a generous number of AI generations per month. To track usage, click your profile icon → “Settings” → “Usage.” If you hit the limit, you can either wait for the next billing cycle or upgrade to a paid plan.
• Common pitfalls to avoid

- Over‑relying on AI – Use Lex as a starting point, not a final copy. Always review and personalize the output.

- Vague prompts – Be specific. Instead of Write about marketing, try Write a 3-paragraph introduction to a guide on social media marketing for B2B startups.

- Ignoring the inline toolbar – Don’t miss the ability to select text and apply AI actions (rewrite, shorten, expand). It’s the fastest way to refine specific parts.

• Performance optimization tips

- Use keyboard shortcuts: Press Cmd+Enter (Mac) or Ctrl+Enter (Windows) to trigger AI generation without reaching for the mouse.

- Work in short bursts – The AI works best when you feed it one idea at a time. For long documents, write each section separately.

- Leverage templates – Lex offers pre‑built templates for emails, blog posts, and more. Start from a template to save time.
