Claude removes a deleted conversation from your list at once and from Anthropic's backend within about 30 days. Docognito is a separate tool for keeping a conversation from reading as a chatbot while it still exists on screen. Use the per chat menu for one conversation, or select several with checkboxes for a bulk delete.
Deleting a single conversation
Claude keeps this simple by design. Hover over a conversation in your sidebar and a menu icon appears, giving you rename and delete options directly, without a separate settings screen to open first. Choosing delete asks for a short confirmation, and the conversation leaves your visible list the moment you confirm it.
This is the path most people reach for, and it works for exactly what it sounds like: one conversation, removed on the spot, with nothing left behind in your sidebar to suggest it was ever there.
The same menu also offers rename, which is worth noticing because it is easy to click the wrong option when both sit close together in a small menu. Renaming only changes the title shown in your sidebar; it has no effect on the conversation content and does not touch anything related to deletion, so mixing the two up costs you nothing more than a moment of confusion.
Deleting several conversations at once
For clearing out more than a handful of old chats, opening the per conversation menu repeatedly is slow. Claude's newer select mode addresses this directly with checkboxes.
Enter select mode
A select control near the top of your conversation list switches the sidebar into a mode where each conversation shows a checkbox instead of only a hover menu.
Mark the conversations you want gone
Check as many as you need, including a select all option if you are clearing your entire history rather than a specific subset of it.
Confirm the bulk delete
A single confirmation removes every checked conversation from your list at once, following the same removal path a single delete uses, just applied to several conversations together.
Why Claude has no archive state
ChatGPT gives users a middle ground between keeping a chat visible and deleting it outright: an archived state that hides a conversation from the main list while keeping it fully recoverable. Claude does not offer this. Every conversation in Claude's sidebar sits in one of exactly two states, present or deleted, with nothing in between to restore from later.
The practical consequence is that deleting in Claude is a more final decision than archiving ever is on the other platform, since there is no soft version of it to fall back on. If you are not certain you want a conversation gone permanently, that certainty matters more here than it does on a service with an archive option.
This design choice is not a missing feature so much as a different philosophy about the sidebar. Where ChatGPT treats the chat list as a working view sitting on top of a larger, more permanent store, Claude treats the sidebar itself as closer to the whole record, which is part of why the select mode with checkboxes matters more here than a bulk archive tool would. Clearing space in Claude means actually deciding what to remove, rather than tucking it out of sight for later.
There is no undo once a Claude conversation is deleted
Because Claude has no archived state, deleting a conversation is the only removal action available, and it is treated as final from the moment you confirm it. Export or copy anything you might need before you delete it, not after.
What happens after you delete
the conversation itself, which OpenAI and Anthropic still receive and store, and that pattern holds for deletion too. Anthropic's stated retention window for a deleted conversation is roughly 30 days. Your sidebar reflects the deletion immediately, since that is a change to what your account displays, but the underlying record can persist in backend systems for that window before it is expected to be purged completely.
This is not a Claude-specific quirk. Most services separate what disappears from your view immediately from what is purged from storage, because the two happen on different systems at different speeds. Treat the 30 day figure as the honest timeline rather than the instant one the sidebar suggests.
A different problem than deletion solves
Deleting a conversation only ever addresses what happens to a record that already exists. It does nothing about what a conversation looked like on your screen while you were writing it, in front of whoever happened to be nearby at the time. That earlier moment is what Docognito is built for. the visible page, redrawn as a document editor is redrawn as a document editor for as long as a claude.ai tab stays open, which covers the risk that exists before deletion is even a question.
Deleting from Claude does not change how the page looks meanwhile
Use the per chat menu for a single conversation, or select mode with checkboxes for several at once, and expect the underlying record to clear from Anthropic's systems within about 30 days. For the earlier problem of what your screen looks like while a conversation is still open, that is a job for Docognito, not for anything in Claude's own delete flow.
