the system is great, to breakdown and analyse components and follow its logic is impressive when compared to other platforms. It still has quite a long way to go until it achieves the ideal service. I think that it’s price point is predatory and inflated by at least 30%. I think the developers need to have a long-term view on market share, aggregation, and profitability.
Great product. Would be good if we have reader mode when highlighting webpage in app
Exceptionally
A reader mode just like the Safari when you are highlighting would be a great feature
Great app - very useful.

Liner is a simple, effective and well supported app ... allows me to quickly find important focus points/issues when sharing important information.
love the app but it’s stupidly expensive

the subscription is too much, like comparatively double that of any remotely similar apps when this theory could be realistically implemented in any free notetaking app such as noto, craft, or notion etc.
