Privacy-first AI surveys with end-to-end encrypted responses
Responses are encrypted on the respondent's device before upload, so only the survey owner holds the key and can decrypt the data.
Generate structured, less biased questionnaires from a prompt, refine wording, create answer options and add skip logic and multilingual support.
Automated thematic analysis, sentiment detection, anomaly flagging and data encoding turn open-ended answers into usable categorical insight.
Run natural back-and-forth interviews with dynamic follow-up questions that adapt to each respondent for deeper qualitative data.

Answer security questionnaires, RFPs and buyer portals with cited answers from your own docs.
Upload SIG, CAIQ, HECVAT, DDQ and RFP files as XLSX, DOCX or PDF and get filled answers back with the source cited for each.
The Chrome extension detects and fills vendor risk management portals such as OneTrust, Whistic, ServiceNow and Panorays, plus spreadsheets.
Wolfia pulls in Google Drive, Confluence, Notion, Slack, SharePoint, Drata and GitHub so answers always reflect your current policies.
Approved reps can ask @wolfia in Slack and get an answer with the policy it came from, without waiting on the security team.
