What this app is. What it isn’t. What you could build.

One-liner

A note-taking app that lets you annotate, organize, and connect ideas across PDFs, web pages, and documents with a fluid, spatial interface.

Strengths

Highly praised for its unique spatial annotation system that allows users to freely move text fragments around the canvas ("I can finally think in a non-linear way").
Strong support for PDF annotation and document manipulation, especially useful for researchers and students ("Perfect for highlighting and organizing research papers").
Intuitive drag-and-drop interface for reorganizing content, enabling dynamic idea mapping ("It’s like mind-mapping but with real text").
Seamless integration of web clips and PDFs into a single workspace ("I can pull in articles and instantly link them to my notes").
Consistently rated as one of the best tools for deep reading and knowledge work ("This is the only app I use for academic writing").

Weaknesses

Frequent complaints about performance lag on older devices or large documents ("The app freezes when I open a 50-page PDF").
Lack of offline access on iOS ("Can’t use it without Wi-Fi—this defeats the purpose for travel").
Steep learning curve for new users unfamiliar with spatial note-taking ("It took me days to figure out how to do basic things").
No native mobile app for Android ("Only available on iPad and Mac—no way to use on my phone").
Limited collaboration features compared to competitors like Notion or Obsidian ("Can’t share or co-edit with others easily").

Opportunities

Build a lightweight, fast version optimized for mobile-first users with offline support and better performance on low-end hardware.
Add real-time collaboration features with minimal friction—ideal for remote teams or study groups.
Create a browser extension that captures and auto-organizes web content into LiquidText-style spatial notes.
Develop a simplified 'starter mode' with guided workflows for users overwhelmed by the spatial interface.
Offer a tiered pricing model with a free plan focused on core annotation and basic organization.
