Yes. Attach a bill, receipt, or past email and Genie reads it for context — so your letter cites the right names, dates, and details. PDF, DOCX, JPG, and PNG are supported.
Attachments are for context only. The file itself is never stored: it's screened for safety, read in memory to pull out the text, and then discarded. Only the extracted text becomes part of your letter's content.
One caution: text pulled from a file automatically may be incomplete or inaccurate. Please confirm any details drawn from a file — account numbers, dates, amounts — before approving your letter.
