Threads
Branch any answer into its own focused conversation, without losing the thread of what you were doing.
Branch off any answer
Most of the time you talk to Chalie in a straight line — one message, one reply, next message. But sometimes you want to dig into one specific answer without derailing everything else. Reply directly to any answer and it opens into a thread: a focused side conversation that branches off that exact reply, while your main conversation stays exactly as it was.
Getting started:
- Hover over any answer and click the reply icon to branch it into a thread.
- Keep asking follow-ups inside the thread — it remembers everything said there.
- Come back to the main conversation any time; nothing you did in the thread changes it.
The thread panel
Opening a thread slides in a focused panel showing that whole exchange from the start — your original question, Chalie’s answer, and every reply since. It’s a separate space: you can have a thread open with its own back-and-forth running while the main conversation sits untouched behind it.
Close the panel and reopen the thread later — everything is exactly as you left it.
Automatic labels
The first time you reply into an answer, Chalie quietly reads that opening exchange and gives the new thread a short topical label — three to five words, enough to recognize it in a list. This happens on its own in the background; you don’t need to name anything. The label appears in your conversation list moments after the thread is created, without needing to refresh.
Finding a thread again
Every thread you’ve branched off is searchable. Open search (the search icon, or ⌘K / Ctrl+K) and type a keyword — Chalie matches it against anything you said inside that thread, or against its auto-generated label, so you can find a thread either by what you asked or by what it turned out to be about.
Setting how hard Chalie thinks
Each thread has its own thinking-effort setting, separate from the main conversation and from every other thread. Leave it on Auto and Chalie decides per-message how much deliberation a reply needs, same as normal. Pin a thread to Medium or High when you want it to always think harder — useful for a thread where you’re working through something genuinely difficult and don’t want it second-guessing whether the question deserves the effort.
The setting sticks to that thread. You can have one thread pinned to High for a hard problem while everything else runs on Auto.
Keep typing into a busy thread
If a thread is still generating a reply, sending another message doesn’t interrupt it and doesn’t get lost — it queues. The moment the thread finishes what it was doing, everything you queued up sends together as one follow-up. This means you can fire off a few follow-up thoughts in a row without waiting for each reply first; they’ll all be there, in order, the moment the thread is ready.
The main conversation and any open thread queue independently — being busy in one never blocks or queues anything in the other.
How threads relate to memory
A thread’s content isn’t lost once you leave it. Like the rest of your conversation, what happens inside a thread feeds into Chalie’s memory over time, so something you worked through in a thread can still come up later in an ordinary conversation. See Memory for how that recall works.
Threads are for this conversation’s detour — a place to dig into one answer without cluttering the main line. They’re not a separate memory system, just a separate view onto the same conversation.
