The problem

Researchers kept interview quotes in one tool, sources in another and their synthesis in a slide deck. Every time they wrote up a finding they lost the link back to the person who said it.

Approach

A quote in Fieldnotes is an object, not text. It carries its source, timestamp and tags wherever you paste it, so a finding in a report still opens the minute of the interview it came from.

I prototyped the editor in code from week two. Dragging a quote between notes, and what happens to its source when you edit it, were questions a static mock could not answer.

Fig. 2Quotes keep their source, even three documents later.
  1. Findings are written as sentences, so a synthesis reads like a report instead of a wall of stickies.
  2. Every quote keeps its speaker and timestamp, even after it is pasted into another document.

Details

The sidebar collapses to icons at narrow widths instead of disappearing. Search opens on the slash key and filters by tag, person or date as you type.

  1. Type a tag or a name and it turns into a filter. There is no filter panel.
  2. Enter opens the quote inside its interview, at the minute it was said.
  3. Findings and raw notes share one index, so a finding links back to every quote behind it.

Outcome

Fieldnotes left beta in June 2025. The component library I built is now the team's design system, with docs written next to the code.

“Most designers hand you a picture of the editor. Ines handed us the editor. We shipped her prototype’s drag interaction almost line for line.”
