Handles portals you haven’t seen before
First time on a new portal? FillBase detects the questions and fills them automatically. No setup, no config, no waiting for support.
Review before you submit
Every answer appears in a side panel with confidence scores. Edit, skip, or approve — nothing gets submitted until you say so.
Same answers, every channel
The extension pulls from your SOC 2, policies, and past approved questionnaires — the same source of truth your Slack workflow uses. No conflicting answers between portal and spreadsheet.
- Confidence scores and source citations on every answer
- Fill all questions at once or one at a time
- Consistent responses whether the buyer uses a portal or a spreadsheet
