Minimalist interface that feels like Google Docs but better. Markdown shortcuts, keyboard-driven, no toolbars.

The honest take

✓ What works

The cleanest writing interface on the web — better than Google Docs for serious writers
AI feels integrated, not bolted-on like Notion AI or Docs AI
Generous free tier for casual writers
Built by writers who use it daily — every detail is intentional

✗ What doesn't

Free tier caps at 10 AI runs/month — heavy users hit the wall fast
No collaborative editing (yet) — Google Docs still wins for teams
Limited formatting compared to Notion or Docs
No mobile app — web only

Verdict

Lex is one of the best-known writing tool on the market in 2026. The free tier alone is worth a signup, and the paid plan is priced fairly compared to peers. If you're shopping for a writing tool tool, put Lex on your short list.
