What is a more efficient substitute for Notion?

Notion is sluggish and missing offline support. Which note-taking app offers faster response times and offline capabilities for a smoother workflow?

After struggling with the sluggishness and dependency on internet connectivity in Notion, I decided to switch to Obsidian. From personal use, I found that Obsidian offers a highly responsive interface and completely local storage, which has significantly improved my workflow. Its markdown-based approach may seem different at first, but the speed benefits and offline reliability make up for the learning curve. The ability to customize and extend its functionality through plugins further enhanced its efficiency for my note-taking needs.
