What's New in Chunk

2.5.2

July 19, 2026

Our biggest update yet. Universal Search for all your data + Design updates! Automations — set it once, let Chunk do the work Automations are standing AI agents that keep working while you don't. Set one up in a few taps and Chunk runs it on a schedule, then delivers a clean, cited digest. • Research — re-run any question on a cadence and get only what's new, summarized with sources • Watchers — track a price, a restock, or a page change and get alerted the moment it moves • Digests — a weekly roundup of your own notes, stale-note nudges, and connections you'd have missed • Agent Tasks — hand Chunk a job across your notes and the web; it plans, works, and drops the result straight into a note or report Save to Chunk — capture anything, from anywhere Share a link, article, screenshot, or PDF from any app right into Chunk. Your Inbox files it for you: AI titles it, tags it, and suggests the right folder and note links. Send it to a Collection in one tap, or keep it for later. Works from the Share Sheet, Siri, Shortcuts, and the Action Button — on iPhone, iPad. A warmer new look We've rolled out Paper & Ember — a calmer, more focused design across the whole app, with cleaner cards, better dark mode, and color accents that make everything easier to find. Plus dozens of fixes and refinements across Settings, account management, and overall reliability on iPhone & iPad.

Ehh it’s tough to import information in

I should have never subscribed but alas here we are.

The good:
- clean UI
- nice MacOS counterpart
- built in LLMs do work

The bad:
- it is very hard to get information into this app on iOS. With respect to each productivity app I’ve used, I always import 10 or so random stock related files (in different formats) to see how the app handles the uploads. Well, unfortunately, the only information i was successfully able to import was an Apple note and a URL. Had no luck with PDFs, .jpegs, sharing from X, sharing from email, sharing from files or from photos.
…..and that’s when i gave up interest because if you can’t easily import and export information into an PKM or second brain app, then it serves no purpose. See HyNote….it is hands down the best all encompassing productivity tool on the market - across any device or platform - but it’s harddddd to get information into it for processing (and out of it for incorporation into a larger note system). Recall is probably the second best tool but it just doesn’t have a great iOS UI and doesn’t have a macOS app.

Response from developer

I'm not sure what happened with your experience. I'm deeply sorry you had such a poor first impression of Chunk. One of the things that makes our app special is the ability to upload lots of documents and files to Chunk and search them easily. I wish you would've reached out to us so we could've made things right for you and fix any issues you were having. We'd love to have you back if you're willing to give us another chance. We had a day or two of outages last month that you may have just been unfortunate enough to use at those times. Again I'm sorry this happened to you, if you do try Chunk again, please send me an email if you have ANY issues or questions. Thanks - James founder of Chunk AI

Duped by the Aesthetically Please UI

Nearly impossible to get information/files/anything into this app on iOS which, in turn, makes it pointless across the Apple ecosystem. Waste of $

Powerful AI Companion

I have used a lot of AI tools and this is the best I have used to date!!

Amazing

I started using this app for grad school and it has seriously changed how I study. I have ADHD and usually get overwhelmed trying to keep track of everything I read, especially for technical subjects. Chunk helps me slow down and actually think through what I am reading. It lets me focus on the important stuff without getting distracted or lost. It feels like it was made by someone who actually gets how hard reading can be when your brain is bouncing all over the place. I use it pretty much every day now. It is simple, clean, and really useful. If you do a lot of reading or research and struggle to stay organized or focused, this is worth trying.
