What's New in Version 3.0.3



- Write freehand ink on your documents, your excerpts, your comments, and even directly on the workspace!


- You can link any point in any object (i.e., document page, excerpt, workspace, comment, etc.) to any point in any other object—just by drawing a line from one to the other! When you draw a line between objects, the app creates a “live” Ink Link that updates as the objects move, and fades if the objects get far enough apart.

- LiquidText puts persistent link-buttons on both ends of the Ink Link; tap one to retrieve the object on the other end!

- Create as many of these Ink Links as you want, make mind maps, show how different documents relate, show how ideas on different pages connect, or cite which documents and sources inspired your ideas.


- Draw a large circle, box, or other shape in a document, and a small button appears—drag the button and a freeform excerpt is instantly created from whatever was in the circle/box/shape!
- Connect these freeform excerpts together to form groups, just as with all LiquidText excerpts.

Customer Reviews

Really changed the way I research

I'm loving this app. It has made my research more memorable, organized, and retrievable--all the things I need to continue my dissertation research. I do have two complaints, however. (1.) I can only highlight a PDF, I don't seem to be able to underline or cross out. (2.) I cannot edit highlights or see notes that existed on the PDF before uploading it to LiquidText. With these two features this would be 5-star app. Add a text reader in which I can adjust the voice and pace, and I would pay three times what I paid for this app.


Has become better with every release. Being able to use the pencil is a game changer. This supports my thinking while reading like no other app. The price is remarkably low. Looking forward to more improvements.

Crashes...No Trial of Ink...

Crashed on load. Rebooted, crashed on load again.
No trial of inking...just a $9.99 upgrade.
