Did you like it?
What it does
Drop in a month of your calendar. Read it back as a statement of where the hours actually went.
Who it is for
For anyone whose week is booked solid and cannot say by what.
Notes from the making (7)
  1. launched — drop a calendar export, get thirty days back as a statement
  2. the calendar is read in the browser and never uploaded; there is no server that could hold it
  3. classification is deterministic first — a model sees only the titles of commitments no rule could place, and only if you let it
  4. €9 for the whole history instead of a month
  5. one click instead of a calendar export — connect Google, approve, results, with the token issued to the page and handed straight back
  6. declined meetings, meeting rooms and holiday feeds are thrown away before anything is counted
  7. staged: the calendar file is the whole product, and the one-click connection waits behind Google’s review rather than holding the experiment up

This page stays up whatever happens to the experiment. The record it is drawn from is public: /api/nothing/experiments.
