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.

The AI super app for work — tasks, projects, calendar and meetings in one place
Motion reads priorities, deadlines, dependencies and durations, then continuously builds and re-optimizes a daily plan and warns you when tasks are at risk.
Describe a project and Motion generates its tasks, deadlines, stages and assignees in seconds, then keeps statuses updated and flags delays automatically.
Join meetings and produce summaries, action items and follow-up emails, with recordings and transcripts that link back into your tasks and calendar.
Draft, proofread and organize documents with AI, and ask questions across your docs, notes, projects and tasks to find anything instantly.
