Show HN: Script to bulk delete Claude chats from the web UI

I have a similar complaint every AI chat product I've used. There's no way to multi-select conversations and delete them in a single action. It's either delete all or click on the delete button and confirm for every single one.With many leaders in tech claiming that AI agents have drastically reduced the time and cost of shipping features, how do such small usability problems still not get fixed after years?

For pure, weird, late-night LLM chats, I've recently started using Qwen3.6-35B-A3B-Uncensored just running with llama-cli and it is a very refreshing chat experience.Uncensored model means it will not deny any requests (at least I have yet to come across one), if you grew up in the 90s it sort of feels like coming across the anarchist cookbook for the first time (though with more accurate content). Using llama-cli means the session is entirely local and entirely ephemeral. As a bonus all the reasoning steps are fully visible to the user.The base Qwen3.6-35B-A3B is more than adequate for "weird late night brainstorming chats" and I've really started to dislike the natural tendency to self-censor when the model is willing to refuse (and potentially report) any requests it feels is "inappropriate" and all these private thoughts are stored on someone else's server.

The Claude (and ChatGPT) web UI supports incognito/temporary chats that are discarded when you close the tab. Click the ghost or dotted speech bubble icon in the upper right corner of the page.I use this as my default mode so I don't clutter my chat history with random, one-off questions I ask. Unfortunately, there is no way to change your mind and save a productive incognito chat after you've started chatting.

Wouldn't downloading conversations be more useful? If you've input something into Claude that you don't want a future trillion-dollar US company (a bicorn?) to know, this script won't help I'm afraid. Free reminder that local AI exists and works well if you're willing to tinker a bit.

How are you managing it with ChatGPT? I've always found Claude relatively easy to do it with, but unless they've changed it in the last few weeks it's hard with ChatGPT.Edit: I should add I often want to keep one or two reference chats, so the "nuke all chats" button doesn't work for me.

Which of course assumes, that the "delete chat" function actually deletes anything from Anthropic's datastore.
