Diary and usage studies

Everyday life,
before memory tidies it up

An online diary study asks people to report close to the moment, in text, photos, video or audio, over days or weeks. On Qualzy you see what they actually did rather than what they remember doing, with the routines and attitudes behind it, and every entry is summarised as it arrives.

Examples of what you can research

Habits people don’t notice they have

Diaries

Routines and habits

Meals, commutes, the morning rush, a weekly shop. Anything that happens repeatedly is easy for memory to flatten. An entry each time it happens shows the variety, and the photos show the fridge, the shelf and the mess afterwards.

Usage and attitudes

How a category fits into people's lives

Screener data, attitude scales and open answers in one project, so the numbers and the reasons sit side by side. Ask about specific occasions rather than behaviour in general, and you get moments instead of self-image.

Before the interview

Pre-tasks and homework

A few days of entries before an interview or group, so you walk in already knowing how people live. Discovery Research run short projects of one to two weeks this way, ahead of in-person groups and IDIs.

What a week can look like

Seven mornings in one breakfast diary

An illustrative example rather than a real participant, but a familiar pattern. Asked on day one, Sam would probably have said breakfast happens most days.

  1. Mon Photo

    Toast, eaten standing up. The kids' lunches came first.

  2. Tue Video 0:48

    Here's the cupboard. The cereal's for them, the granola's mine.

  3. Wed After a reminder

    Skipped it. Meeting at eight, so just a coffee on the way in.

  4. Thu Voice note 0:32

    Breakfast bar from the station kiosk. Not proud of it.

  5. Fri Photo

    Bacon roll. Friday rule.

  6. Sat Video 1:20

    Everyone at the table for once. This is what I wish weekdays looked like.

  7. Sun Looking back

    Reading my week back: I sat down to eat twice.

What the week shows. By Sunday, reading back over their own entries, Sam had noticed the pattern too. The gap between the routine people describe and the one they actually live is what a diary is for.

Capturing it

Ways to catch the moment

A diary form on a phone, with multiple choice, photo upload and ranking questions, beside the researcher's view of the answers

Forms & Diary Entry

Repeated entries, once a day, once a week or each time something happens, for days, weeks or months. Keep the core questions the same each time so entries can be compared, mix scales with open questions about why, and let people look back at their own previous entries. Forms add survey-style structure, with conditional logic and screener data, inside the same project.

Video uploads from participants with transcripts and AI summaries

Video, audio and image uploads

Photos are the workhorse of an online diary, and video adds explanation and feeling. Every video and audio upload is transcribed and summarised as it arrives.

Participants' social posts with photos, and AI summaries above each one

Social Posts

Text, photos, video and voice notes in one response, posted from real situations: at the supermarket, while cooking, after using a product. Posts can be private, or open for comments.

Journeys

When the experience has stages, such as moving house, choosing a mortgage or recovering from an operation, a journey activity adds a score at every stage. The journey chart shows where things rise and fall, and the entries explain why.

How a study runs

Diaries that people keep up with

Automatic nudges

Automatic reminders keep people on track, so you're not chasing them by email on day three. Check who's up to date each day and contact anyone falling behind while there's still time to catch up.

On any device, wherever the moment is

People take part in a browser on their phone, tablet or computer, with nothing to install, so they can make an entry where the behaviour actually happens.

A forum or an AI-moderated chat

Diaries run in the familiar forum, or as their own self-contained chat with multiple entries, where an AI moderator follows up against the goals you set, asking for the detail that's missing or a better photo.

A few weeks or a few months

Most diaries run for one to four weeks as a Qualzy Discussion. For a longer view with the same people, run them in a Qualzy Community.

"We used to ask for input in pre-tasks and get them to email things. Now it is all captured in one place inside Qualzy."

From entries to the debrief

Weeks of entries, without weeks of reading

  • Key points on every entry. Each entry is translated if needed, summarised and broken into key points as it arrives, with the participant's own words behind each one.
  • Maizy Chat while the diary runs. Ask how weekday and weekend routines differ, or what people say on the days they skip breakfast, and check the answer against the evidence.
  • Themes once the diary closes. Build themes across every entry, with the quotes and clips that support each one.
  • Still read some diaries end to end. The way one person's account changes across a fortnight is often where the real finding is.

Diaries in practice

Discovery Research

A window into participants' lives

Discovery Research, a full-service UK agency, runs short projects of one to two weeks as pre-tasks before in-person groups and interviews, with participants uploading photos and videos from their everyday lives, and AI analysis to keep up with the volume.

"Qualzy gives us a window into the lives of our participants and has the tools that allow us to analyse and understand those lives."

Hamish Kynoch, Head of Qualitative Research, Discovery Research

Feeling Mutual

Behaviour captured in the moment

Feeling Mutual use photo diaries alongside video uploads and screen recordings to capture behaviour as it happens, such as during an EV charging session, rather than from memory afterwards.

"With Qualzy, participants can upload mobile videos, complete a photo diary, or share text about their thoughts, anxieties, and frustrations. Qualzy helps me delve into the intricacies of their lived experiences."

FAQ

Designing a diary that works

How long should a diary study be?

Usually one to four weeks. Choose the shortest length that gives you enough occasions of the behaviour per person to see a pattern.

Are diary entries private?

Usually, so nobody adjusts their account to match what others have posted. You can open a separate discussion task later if you want people to react to each other.

Can a diary run in the AI-moderated chat?

Yes. The diary runs as its own chat with multiple entries, and the AI moderator follows up against the goals you set. You can also run it as a forum, the familiar way.

Can we combine a diary with interviews?

Yes. Run the diary as a pre-task, then hold the interviews in Qualzy Live, in the same project, so the diary and the interviews are analysed together.

Can people see their own earlier entries?

Yes, whether the diary runs as a forum or a chat. Looking back over a week of their own entries often prompts the most reflective answer of the study, so it's worth asking for one at the end.
