# Conversations

You can keep as many separate chats with Nymbot as you like. Each one is its own thread, its own context and its own title.

## Each chat is its own thread

Press **New chat** and you get an empty conversation. Nothing said in one chat is visible to the model in another — a debugging session and a recipe do not bleed into each other, and the older one costs you nothing while it sits there.

Every chat is a private message thread in its own right: the messages are [gift-wrapped](https://nymbot.ai/docs/encryption/) individually, published to relays, and reassembled on whichever device you sign in from. Sign in on a second device and the whole list is there.

The list is sorted by most recent activity. Search filters it by title and by the text of the messages inside, which is possible only because the decryption happens on your device — the search never leaves it.

## Where the titles come from

A new chat is called *New chat* until you say something. The first message you send becomes its name: the app takes that message, trims it to a short phrase, and puts it in the header and in the sidebar.

Two things follow from that. A conversation that starts "why does this regex backtrack" is findable a week later, and the title is chosen entirely on your device — the server is not asked to summarise anything, and never sees the title at all.

Rename any chat from its header menu if the first thing you asked turned out not to be what the conversation became about.

## What Nymbot remembers

Inside one conversation, the model sees the turns that came before it, so follow-up questions work without repeating yourself. The thread is reconstructed from the encrypted messages themselves each turn; there is no plaintext transcript sitting anywhere.

Older turns fall out of context as the conversation grows — the model is given the most recent stretch of it, not the whole history. If an answer starts drifting from something you established near the top, restate it or start a fresh chat.

Begin a message with `!` to send it with no history at all: a one-off question inside an existing conversation, without the thread's context colouring the answer or inflating the prompt.

## Sending pictures

Put an image link in your message and ask about it. The worker pulls any picture URLs out of what you send and hands them to the model alongside the question, so "what is wrong with this diagram? https://…" works as one message.

Every Claude, GPT, Gemini, Grok and Kimi [Pro model](https://nymbot.ai/docs/models/#pro) can see images, as can the creative and translation routes on the standard tier. A vision reply costs what that model's reply would have cost — there is no separate charge for looking.

> Uploading a picture from the device is not in the standalone apps yet; a link is. [Nymchat](https://nymchat.app) has the upload, and shares this conversation.

## Clearing and deleting

- **Delete a chat** removes it from this device, wipes its archived copies, and tells the server to drop the thread it keeps for context.
- `?clear` empties the current conversation without deleting it: same chat, blank slate, model context reset.
- A [panic wipe](https://nymbot.ai/docs/identity/#panic) takes everything at once — every conversation, your key, and any credits sitting on a [throwaway key](https://nymbot.ai/docs/anonymous/).

> **Careful**

> Deleting is not recoverable. Your history is encrypted to your key and nobody — including us — holds a copy that could be handed back.
