What's New in Chunk

2.6.1

September 29, 2026

GPT-6 and Claude Opus 5.5 are here, along with clearer Private chats and a long list of updates and fixes. NEW • GPT-6 and Claude Opus 5.5: GPT-6 Luna is the new free model, and Pro adds GPT-6 Sol and Claude Opus 5.5. • Siri & Spotlight know your stuff. Your notes, documents, research, collections, artifacts and more are indexed right on your device, so you can find, open and act on them by name. Turn it on or off per device in Settings. Your memories are never indexed. • Stop button: end any answer mid-reply on iPhone, iPad, Mac and Vision Pro (⌘. on Mac). • Private chats: a clear banner shows when a chat is private, and nothing from it is saved to chat history or Memory. • Past chats in Connected Chat: earlier chats now show up in suggestions, search and @-mentions, ready to pin or add to a collection. Pins stay with each chat. • Free research: Free accounts can run one research report a day (Quick Outline, Standard or Resource List). IMPROVED • Chat starters: up to four ideas that fit your screen, plus More ideas. With Pro and Memory on, personalized for you. • Documents: readable titles, Rename, multi-select, and a new Keep Out of AI Answers switch for sensitive files. • Collections: collection chat reads about 3× more of your sources and shows which ones fit, and its chats no longer fill Chat History. • Images: a new image model makes sharper pictures, and edits keep your original look round after round. • Notion: Chunk now searches up to 500 of your latest pages (up from 50) and drops pages you delete or stop sharing. • Keyboard: iPad shortcuts updated for entire app (⌘↩ sends, ⌘, opens Settings), and ⌘1–⌘6 go to the same places on every device. FIXED • Answers no longer run off the screen after you rotate your iPhone or iPad. • Long conversations with Claude no longer fail with an error. • Chat History stays smooth with long histories, and it's no longer blank in languages other than English. • Uploading to a collection now works on iPhone (iCloud files too), and library PDFs and Word files are no longer skipped in collection chat. • Artifacts now come back in the language you choose.

Not bad

Network timeouts keep occurring when the AI is doing something and i leave the app to wait for it to finish and it’s slightly glitchy

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!!
