Solutions · CX & Voice of Customer Organize customer feedback by topic and compare it.

Compare which topics come up over time and alongside different ratings. The original comments help you interpret the differences.

Common hurdles

Your customers say a lot – just not in one place.

And new comments arrive every month. Turning them into something service, product and sales teams can work with takes a lot of manual effort.

  1. The challenge: Every channel on its own

    Survey tool, app stores and ticketing system each produce their own reports with their own categories. Nobody sees whether the same criticism shows up everywhere.

    With deepsight: The same categories for every source

    Analyze every source with the same codebook, including parent and child categories. You see which channels a topic shows up in.

    About your own codebook
  2. The challenge: A score without substance

    The report shows the NPS and perhaps a word cloud. Neither tells you which topics detractors raise.

    With deepsight: Topics by rating group

    deepsight sorts the comments by topic and compares what detractors, passives and promoters mention – with the comments verbatim.

  3. The challenge: Starting from scratch every month

    New export, new count. If the categories come out slightly differently each time, it stays unclear whether a topic is really growing.

    With deepsight: A time series instead of one-off reports

    Add new exports and newly retrieved app reviews as a further wave and align the topics. You see what increases and what decreases.

  4. The challenge: Individual requests get lost

    Among hundreds of comments are complaints, open questions and explicitly announced cancellations. To find them, someone has to read everything.

    With deepsight: Filter by intent

    deepsight sorts comments by intent, such as a complaint, a question or an explicitly stated intention to cancel. Filter these comments and pass them on to your service team.

    Go to intent analysis

Your questions

What your customer feedback can tell you

  • Which topics do customers mention more often this month than last month – and which less often?
  • Which topics are praised, which are criticized – and does a topic tip from praise to criticism?
  • Do new topics appear after a change, such as a new pricing plan or an app update?
  • Do regions, products or customer groups differ in what they write about?
  • For which topics do customers explicitly state an intention to cancel?
  • Which questions do customers ask again and again, for example about billing or contracts?

Good to know: You can also ask the assistant questions like these in your own words. Its answer separates calculation, evidence and interpretation.

Data structure

What your export should contain

One row per comment. What sits next to it determines what you can compare later.

The commentThe free text in its own column; for tickets, only the customer’s message, without your service team’s replies or quoted email threads.
The ratingNPS, CSAT or stars in their own column. deepsight suggests a suitable NPS column when you import data.
Month or quarterIn its own column, e.g. “2026-07”. Used as an attribute, it lets you compare time periods within one file; daily dates are not grouped into months automatically.
Source and channelIf comments from several channels go into one file, put the source in its own column. That way, every comment stays linked to its channel.
AttributesProduct, plan, region, branch or customer group – anything you want to compare groups by.

Good to know: Tickets and comments often contain names or contact details. Anonymization masks details such as names, email addresses or phone numbers before the analyses run. It does not detect every piece of information – check results before sharing them.

A single comment is an anecdote. Sorted by topic, comments show what keeps coming up.

Across all sources, month after month.

Process

From export to topic comparison

  1. Bring in the data

    Upload exports or retrieve app reviews via connector. Filter out empty comments and entries like “no comment” if you wish.

    Data quality check
  2. Set the topics

    Let deepsight suggest topics or apply your codebook. Add product names, plans and internal terms to the study context beforehand.

    Topic analysis
  3. Check against the comments

    Read the comments for each topic verbatim, correct individual assignments, and rename, merge or split topics.

    Topic refinement
  4. Compare

    Put ratings and topics side by side by month, source or customer group, with significance indicators if you wish.

    Group comparison
Results

What you pass on to service, product and sales

Good to know: Your quarterly report is built from tables produced in a different program? The slide factory turns Excel data into slides based on your PowerPoint template.

When service, product and sales see the same topics, everyone talks about the same thing.

Instead of a separate report for each channel.

Methodology

What matters when you compare feedback

Add new topics deliberately

Apply your codebook with additional suggested topics, and you’ll notice what it doesn’t cover yet – after an app update, for example. You decide whether a new topic stays: keep, merge or remove it. Every change is saved as a topic version.

Base per month and source

Shares refer to the analyzed comments of one month or one source; anything the data quality check filters out doesn’t count toward the base. Multiple mentions are possible. With few comments, shares fluctuate strongly – below a base of 10, values are flagged or hidden in group comparison and dashboards.

Every source has its own audience

Customers write tickets when they need something; reviews often come from customers with particularly good or bad experiences. What dominates tickets therefore doesn’t automatically apply to all customers.

Sentiment by topic

A comment like “Great product, late delivery” praises and criticizes at the same time. deepsight therefore classifies sentiment for each topic; check irony and ambiguous wording against the original.
