Open Download Siesta AI and choose Browser extension for your browser. Install it, open its side panel, and sign in. If you already have the extension, open it and continue.
Open the extension side panel and choose the agent for the draft. Set Browser Control to Off so the agent cannot click, type, navigate, or send on the page.
Use Browser Control Off when the agent only needs attached context and must not act on the page.Platform guide: Browser Control

Attach The Text And Request A Draft
Select the relevant message, right-click it, and choose Attach this text to Siesta. Check the attached text, type the tone and maximum length you want, say Do not send it, and select Send in the extension.
Click the copy button below the answer, paste the draft into the reply field, and compare it with the original message. Correct names, facts, promises, links, and tone yourself before sending.
The draft should respond only to the attached note, stay under 80 words, ask for the order date, and remain unsent until you review and send it manually.
The most common problem is attaching too much page context or leaving Browser Control on. Start a new chat, turn control off, and attach only the relevant selection. Next, learn how to work with a document in Summarize a File.
