Ask about a file or an image

1. Add the file in one of these ways:
   • Drag it from File Explorer onto the BoltAI window.
   • Copy it in File Explorer, or take a screenshot, then click in the message box and press Ctrl+V.
   • Click + and choose Attach File or Attach Photo.
2. Ask your question, for example Summarize this in five bullet points.

You can attach:

• Images (PNG, JPEG, GIF, WebP, HEIC), with a model that can see images
• Text, Markdown, CSV, JSON and XML files
• PDFs, with a model from OpenAI, Anthropic, Google AI, Google Vertex AI, Azure OpenAI or OpenRouter

Each file can be up to 10 MB. If a file is still uploading when you press Enter, BoltAI sends your message once it's done.

To see every file in a chat, press Ctrl+I and click Attachments. See The Inspector.

A file won't attach

• "This model can't read …": the current model doesn't take that kind of file. Switch to a model that does, for example one from OpenAI, Anthropic or Google AI for a PDF. See Choose and switch models.
• "Files must be smaller than 10MB": split the file, or attach only the part you need.
• A Word or Excel file: save it as PDF or CSV first.
