iOS app: quote part of an assistant reply, like the desktop citations #14050

Same gap on the Android beta app. Long-pressing assistant text only shows the system menu (Copy, Select all). There's no Cite/Quote action, so the copy-paste-and-mark-up workaround is the only option there too.

From the source, this is shared mobile code, not an iOS-specific limitation. apps/mobile/src/features/threads/ThreadFeed.tsx renders received citations via renderAssistantCitationsAsText, and modules/t3-markdown-text registers no selection-menu action. docs/user/composer.md also scopes Cite to "web and desktop". Could this proposal cover both mobile platforms, maybe as a custom item in the native selection menu (Android ActionMode / iOS edit menu) that builds the citation with serializeAssistantCitation?

Env: Android beta app, server 0.0.46-nightly.20261010.

That would be awesome having this functionality! i am always copying and pasting things down when i am using mobile app version of this!

+1, would use this daily on iOS. Happy to implement in the native-selection-menu shape proposed above once a maintainer OKs the scope.

+1 MISSING THIS ON ANDROID LOL

+1. On mobile I often want to reply to one specific passage, and without Cite I copy it, paste it and mark it up by hand. The native-selection-menu shape @Abdullah1738 proposed (Cite next to Copy, same t3-citation: link as web) looks right. Mobile already renders citations; it just can't create them.

+1 for the iOS app. I follow agent threads on my phone, and when I want to reply to one passage I copy it into the composer and mark it up by hand. The shape Abdullah1738 proposed above (Cite next to Copy in the native selection menu, same t3-citation: link as web) would cover this, since mobile already renders the citations it receives.

+1 from iOS. The shape proposed above (Cite next to Copy and Copy markdown in the selection menu) is what I want. One tap, and the selected text goes straight into the composer as a citation, the same as on desktop.

It would also be good to cite several passages inline before sending, so they collect in the composer the way desktop citations do.

+1 from iOS. I follow agent threads on my phone, and replying to one passage means copy, paste and marking it up by hand. That's my daily workflow right now and it's tedious. The shape @Abdullah1738 proposed (Cite next to Copy in the native selection menu, same t3-citation: link as web) covers it. @juliusmarminge, could you confirm the scope so one of the volunteers can start?

+1 from iOS.

I find T3 code incredibly useful when using from my phone, but this feature being missing makes things tougher than using the desktop version.

+1 from iOS and iPadOS. I use Cite on desktop many times a day to reply to one specific passage. On iPhone and iPad I have to copy, paste and mark it up by hand, so the mobile apps feel incomplete. The native selection menu shape proposed above (Cite next to Copy) would be perfect. PR #29386 already implements it, so it would be great to get a maintainer look at it.

#29386 was closed today because it conflicted with main. Under the new CONTRIBUTING rules I'm not opening a replacement PR myself, since outside contributors can't send features. I'll leave the decision to you.

I see this as parity with desktop rather than a new feature. Desktop can already create citations, and mobile can only show them. This brings Cite to iPhone, iPad and Android.

The work is ready if you want it:

• Branch on current main: https://github.com/marxo126/t3code/tree/cite-mobile-main. It's one commit, with @jakeleventhal and @maria-rcks as co-authors.
• It fixes both open review threads from feat(mobile): select, cite, and comment on assistant text #29386. Citations now use the same rendered-text offsets as the desktop selector, and Cite checks the composer length limit.
• I've tested it on a real iPad Pro 11 M4 and iPhone 17 Pro Max through TestFlight. All mobile tests pass.

@maria-rcks, you kept #29386 up to date. Would you like to take it over, or should I open the PR? I'll only open one if a maintainer asks.

Update: Jake has reopened this as #35306. Please review and test there. The branch below also adds "Go to message" highlighting, which I'm offering to Jake once his branch settles.

I picked up Jake's #29386, which was closed for merge conflicts, and rebased it onto current main. It follows the shape @Abdullah1738 proposed above: Cite next to Copy in the native selection menu, inserting the same t3-citation: link web uses, so the agent sees no difference between desktop and phone.

Branch: https://github.com/an4s911/t3code/tree/feat/mobile-assistant-citations
Two commits: Jake's feature (credited as co-author) and one addition.

What it does

• Select assistant text, tap Cite, and a quote chip goes into the composer.
• Tap the chip to add or edit a comment, copy the quote, remove it, or Go to message.
• Quotes in sent messages open read-only.
• Addition: Go to message now highlights the quoted text in the same blue as web, including quotes that run into bold text.

Mobile only, with no server, contract or web changes. Tested on an iPhone (a sideloaded build of this branch) and an Android emulator. vp run check:changed passes.

	iPhone	Android
Cite in the selection menu
Quote sheet with comment
Go to message highlights the quote
Sent quote, read-only

Would a maintainer be OK with a PR for this? I'm happy to cut it down, for example by dropping the highlight, if you'd prefer it smaller.

Edit: want to help test? Report your device and whether Cite, the quote sheet and Go to message worked, here in this discussion.

iPhone, no Mac needed: download T3CodePreview.ipa from the test release and sideload it with your Apple ID (Sideloadly, AltStore, or xtool on Linux). It installs as "T3 Code Preview" next to the App Store app. Free-account installs last 7 days, and T3 Connect sign-in isn't available in this build, so connect to your server over LAN or Tailscale.

Build from source (Android, or iPhone with a Mac and Xcode):

curl -fsSL https://vite.plus | bash     # installs the `vp` CLI, if you don't have it
git clone -b feat/mobile-assistant-citations https://github.com/an4s911/t3code.git
cd t3code && vp i
vp run mobile:install android           # or: ios
cd apps/mobile && vp run dev:client

Android needs the Android SDK, and the first native build takes 10–30 minutes. Then pair the app with your usual T3 Code server and try citing text in any thread.
