What it is.

It reads survey responses from Google Sheets, groups them into positive, neutral, and negative, then batches them for analysis so the model reads a set instead of one answer at a time.

An AI step generates themes and insights per group, results aggregate into a consolidated report, and that report goes to a summary sheet and a Slack channel on a daily schedule.

What you get.

  • Sentiment grouping across every response before any analysis runs.
  • Batch-based analysis, so themes come from a set of answers.
  • Themes and insights per sentiment group.
  • A consolidated report written to a summary sheet and posted to Slack daily.
HOW TO USE IT

How to set it up.

1

Point the sheet nodes at your own survey data and replace the placeholder sheet ID and name.

2

Rename the expected columns, since the template arrives with non-English column headers you have to change.

3

Check the batch size, because too small a batch produces themes from noise.

4

Add your model credentials and run one day of responses before scheduling it.

5

Set the Slack destination to a channel where somebody owns the follow-up.

6

Keep the raw responses, since a theme is a summary and the quote is the evidence.

Use cases

Themes from a set, not a row

Batch the responses so the analysis sees them together.

Group sentiment first

Sort the responses before any theme work runs.

Report to the channel

Send the summary to Slack so the team reads it without a doc.

Best for

Open-text survey questions

Free-text answers tell you the most and get read the least.

Continuous feedback programs

A daily run turns a rolling survey into a rolling read on it.

Reporting themes upward

Three themes per sentiment group is a report format that survives a leadership meeting.

Questions about Analytics & Attribution

How many responses before themes mean anything?
Should open text be coded by hand or by model?
Strengths
  • It batches before analyzing, so the themes stay stable across runs.
  • Sentiment grouping happens before theme extraction, so a positive theme and a negative one stay separate.
  • The output lands in both a sheet and Slack, so it is readable and keepable.
Limitations
  • The template arrives with non-English column names, so setup means renaming fields before the first run.
  • Themes from a model are a summary, so keep the raw responses for anything you plan to quote.
  • Running daily on a small response volume produces themes from very few answers.
  • Model calls scale with response count, so a large survey carries a cost on every run.
Skip this if
  • Skip it if your survey tool already summarizes open responses for you.
Ideal for
  • Growth analysts
  • Customer success leads
