Attach Evidence
Last updated: October 20, 2026
Some answers are stronger with proof behind them: a SOC 2 report, a penetration test summary, a policy PDF. Evidence lets you attach those files to an answer so reviewers can see them and so they can travel with the project when you export it.
Adding evidence to an answer
Evidence belongs to one answer. In a project with several answer columns, each column has its own files. See Multi-Column Answer Support in Iris Projects.
Open a project and find the answer. Click Evidence in the footer under the answer, or open the Evidence tab, which sits with Citations, Comments and History. A new answer starts with No evidence attached.
Click Upload evidence to pick files from your computer, or Reuse existing to pick a file Iris already has. The line under the buttons keeps count, for example "0 of 5 evidence relationships used".
In Reuse evidence, set Source to Project and media files or Knowledge Map files, search by file name, and choose the file.
Evidence is the third tab, right after Citations and Comments. Each answer has its own list, and an empty one says No evidence attached.
Files can be .pdf, .csv, .doc, .txt, .docx, .xlsx, .png, .jpg or .jpeg. An answer holds up to 5 files, and you can add up to 5 in one upload. If a file is too big, Iris tells you it "exceeds the 75 MB limit". Only a project's reviewer, its participants and people who can view all projects can add evidence, and not once the project is finalized.
Remembered evidence
When an approved answer in the Approved Answers Library has files attached, Iris remembers them. Later, when an answer cites that library entry, Remembered evidence appears in the Evidence tab: "Evidence saved with cited approved answers. Choose what to attach." Click Add beside a file to attach it. Add is unavailable once the answer has 5 files, because remembered files count toward the limit.
Files saved with a cited library answer show up under Remembered evidence, each with its own Add button.
In the Library, open an entry and choose the Evidence tab in its drawer. There, Upload evidence adds files from your computer and Add existing picks files Iris already has. You can upload up to 100 files at once and there is no limit per answer. Library View users can change evidence only on answers they own.
Exporting with evidence
Click More Actions at the top of the project, then Export Project. You'll find it between Notify Unapproved and Link HubSpot Deal.
On the Export tab, pick CSV, DOCX or XLSX. Under Additional Options, check Include Attachments. Check Include Cited Files as well if you want the source documents.
Under Comments, choose No comments, Inline comments or Native Excel comments to decide how comments come along with the export. No comments is selected to start.
Click Export.
Iris builds the files in the background and emails you. The subject starts "Project Export Ready:" and ends with the project name. It contains a link to a ZIP with your export file, a Referenced Source Files folder if you included cited files, a Question Attachments folder, and attachment_mapping.csv, which lists each question with its file names. In the document workspace, the export menu has Include cited files and Include attachments.
Pick a format, check Include Attachments under Additional Options, choose how to handle comments, and Iris emails you a ZIP. The History tab next to Export lists earlier exports.
Media page caution
Evidence files also appear on Media in Settings. Be careful there. Deleting a file on that page has no confirmation, and it hides the file from every Evidence list and from exports, which frees its slot. See Media Library.
