Tool Overviews: What Makes Them Tick

What is Lex?

Lex, built by Nathan Baschez of Every. to is a laser-focused AI writing tool. It’s not trying to be a Swiss Army knife of productivity apps — it’s all about writing flow.

• Core Purpose: Help writers fight blank-page syndrome, refine tone, and push through drafting walls.
• Who It’s For: Freelancers, bloggers, content creators, and anyone spending hours polishing words.
• Differentiator: Minimalism + speed. Lex doesn’t clutter your experience with calendars, databases, or task boards. It’s just you, your words, and AI completions.

My Experience: I often use Lex when drafting blog posts late at night. The blinking cursor can feel terrifying, but with Lex’s AI suggestions, I go from “blank page panic” to a solid first draft in minutes. No distractions, just writing.

What is Notion AI?

Notion AI is the AI-powered extension of the popular productivity app, Notion, created by Ivan Zhao and Simon Last. Unlike Lex, it’s designed to supercharge knowledge management and workflows.

• Core Purpose: Help teams and individuals summarize, rewrite, expand, and analyze content without leaving the workspace.
• Who It’s For: Teams juggling docs, wikis, tasks, and databases — basically anyone who thrives on organization + AI.
• Differentiator: Context awareness. Because Notion AI sits inside your existing workspace, it understands the surrounding content and workflow. Summaries, insights, and content expansions feel smarter and more actionable.

My Experience: I’ve used Notion AI to summarize messy meeting notes and convert them into actionable bullet points. It’s like having a virtual project assistant that never forgets a deadline.

Switching tools is never just “copy-paste.” Here’s what you should know:

Advanced Workflow Hacks: Getting the Most Out of Each Tool

Lex Hacks

1. Use AI Completion Early: Don’t wait until you’re stuck — let Lex generate a skeleton draft to spark ideas.
2. Sentence-by-Sentence Refinement: Instead of finishing a whole paragraph, tweak sentences as Lex suggests. Faster flow.
3. Offline Drafting: Draft without distractions and sync later — Lex keeps your ideas intact.

Notion AI Hacks

1. AI Summarize Pages: Perfect for long meeting notes, research articles, or multi-page docs.
2. Task + AI Combo: Add AI-generated notes directly to tasks or project boards — no manual copy-paste.
3. Template Automation: Create AI-powered templates for repetitive workflows like SOPs or client briefs.

Learning Curve & Data Policies

• Lex: Plug-and-play. You can start generating content in minutes. Data stays minimal, giving freelancers peace of mind.
• Notion AI: Longer setup. Learning how AI interacts with databases, tasks, and wikis takes practice. Enterprise-level data policies add security but require attention.

Personal Note: I spent a week training Notion AI on my own workspace. Once it “learned” my context, the summaries and suggestions felt almost psychic — worth the setup if you manage complex projects.
