Chat with your documents

Reader's Chat feature allows you to chat with documents as you're reading. This is currently only available on the web and desktop versions of Reader, but we plan to reciprocate the feature to mobile as we continue to develop it.

To access the chat, open any document and click Chat in the right sidebar (or hit the backtick ` twice to cycle between the panels).

The language model has access to the underlying document, its metadata, and your reading position, so it's more effective than other Ghostreader prompts at extracting detailed information, clarifying random questions that come up while reading, and applying the writer's concepts to domain-specific situations. The LLM also has access to the chat history, so you can more naturally ask follow up questions.

Save chat responses

If you get a particularly useful or evocative response while chatting, you can save it to the document's note field. Not only will this separate the note out from the chat interface, it will also allow it to be synced to Readwise with the rest of the document's notes and highlights.

To save a response to the document note, click the notebook icon below the response.

Additionally, you can use the Copy icon to save the response to your clipboard for use elsewhere.

Change the GPT model

By default, it uses OpenAI's GPT-5.1 model with fairly low thinking for quick replies, but you can optionally switch to a more thoughtful version of the model if you'd prefer to trade speed for intelligence.

To change the model, click into the dropdown menu at the bottom of the chat field.

Clear the chat history

If at any point you'd like to start fresh with a new chat, you can click Clear chat at the bottom of the Chat panel. This will erase all of the current responses, so make sure you've copied or saved anything you might want to keep before you click this!

Use preset prompts

Ghostreader comes loaded with a variety of default prompts, and you can also customize them or create your own.

To use a preset prompt, open the Preset prompt dropdown at the bottom of the chat window and select the prompt you'd like to run.

The preset options will vary based on the scope of the selected text. That is to say, you'll see a different set of options if you have a word or two selected in the document versus if you have a full sentence or paragraph selected. If you have nothing selected, the listed prompts will be for the full document content.

To quickly access the preset prompts, use the G keyboard shortcut for selected words or passages, or use shift + G to run a prompt on the full document.

If you'd like to save a particular chat response as a highlight note, you can use the Copy option below the response, then use the N keyboard shortcut to edit the highlight note and paste the Ghostreader note.
