What a single sentiment score misses in product feedback

Short answer

AI sorts feedback on B2B products by the topics it concerns and keeps both experiences from one comment, for example praise for the manual and a complaint about setting up the machine. A single “positive” or “negative” score will not show that. Consider your own model when a ready tool keeps losing distinctions that matter for the product.

Customer feedback and AI: statistics 2026

22.5 h

fewer correction hours a month at 3,000 comments: a ready topic tool cuts errors from 20% to 10%, fine-tuning to 5%. Scenario.

Figures checked: 22 October 2026

From comments to a conversation about the product
  1. 01Commentthe client's whole text
  2. 02Passageseach topic separately
  3. 03Topicsa list agreed with the product team
  4. 04Summarynumber of clients and quotes
  5. 05Decisiona question for the next conversations

Two topics in one comment

Say a client using a machine writes: “After a format change we spend a long time setting the guides, but the manual is clear”. The product researcher needs to find this statement both when reviewing comments on format changes and when discussing the documentation.

A useful summary keeps both threads. Under preparing the machine for work, it shows the remark about time-consuming guide setting. Under the manual, it records the positive view of how clear it is. Both entries lead to the same original statement, so the person reading the report can see them together and check the context.

The product team gets a concrete topic for discussion this way: what exactly is hard about a format change, when the client rates the manual well? It can go back to the author of the comment or look for other statements about that stage of work. It does not have to re-read every comment tagged as general dissatisfaction.

This one remark does not establish whether the machine has a fault, how long setting up takes or how often other clients have a similar experience. It supplies questions worth investigating.

From a set of B2B product comments to a conversation about the product

The person preparing a feedback review often reads the same material several times, each time from a different angle. Once they look for remarks about start-up, another time about daily use. If the statements exist only as long notes or a single sentiment score, they have to rebuild that split themselves.

A helpful tool shows the comments about a chosen part of the client's experience, with praise next to difficulties and suggested changes. The researcher reads the original statements, corrects the assignments and prepares a summary for the product meeting. With access to the source, they can check details a short topic name does not capture.

Check the features you already have

For a small set of comments, a shared topic list and manual tagging may be enough. They also help settle what the team means by “format change” and when a comment is about the documentation. Without that agreement, differences between the people tagging feedback can look like a model problem.

Ready text analysis tools can also assign topics. Qualtrics describes in Text iQ tagging statements for reporting, automatic assignments based on search queries, and manual corrections. Which features you get depends on the tool's edition. Test the version you use on your own comments before you order a separate model.

You can run a similar trial with an available language model and clearly described topics. If it keeps both threads from mixed comments and the researcher rarely corrects the assignments, further adaptation may not be needed. What matters is the result on comments about your product, in the languages you actually receive them in.

When adapting the model is justified

The reason for further work is a recurring mistake the team can explain. The model may, for example, regularly treat remarks about setting the guides as a rating of the manual, although the comments are about the effort of preparing the machine. A person who knows the product then shows which distinction the summary has to keep.

One way to adapt a model is fine-tuning, further training of an existing model on correctly assessed examples. In such a project the goal is recognising company and industry wording and assigning remarks to the agreed topics. First, though, you need to establish whether the errors remain after the topic descriptions are improved and the available solutions are checked.

The researcher reviews mixed comments that were not used for adaptation. They record how many assignments need correcting and what the corrections concern: a missed thread, the wrong topic or a rating attached to another part of the statement. They also check comments the current tool handles well. Such a comparison shows the work that remains in preparing the summary and helps judge whether an adapted model is worth maintaining.

If what you need most is a report of the symptoms reported in complaints, the article on fine-tuning for sorting quality complaints will help. It covers reported quality problems, while product research also covers praise and suggested changes.

A feedback summary for the product team's work

Syntalith builds apps and adapts AI models. We propose a tool in which the team reviews feedback by a chosen topic, sees the original statements and corrects the assignments. The aim of the project is to prepare material for the product conversation without sorting the same comments again from the start.

The client's team names the topics that keep coming up at meetings and examples of wrong assignments. We check what the current tool provides and set the scope of the app from that. Where there are recurring difficulties in recognising the product's language, we also compare the result of adapting the model. The proposed connection to the feedback source should let you go back from the summary to a specific statement.

Describe one situation in which an overall feedback score did not help the team understand the client's experience. Tell us where you keep the comments and who prepares the review today. That is the starting point for a conversation about the scope of work; information about working together is on Syntalith's pricing page.

What a B2B product feedback model costs and what it saves

Scenario: 3,000 comments a month
Today: 20% errors × 3,000 × 3 min
30 h × €34.90 = €1,047
After a change without training (a ready topic tool): 10%
15 h (€524)
After fine-tuning: 5%
7.5 h (€262)

Fine-tuning saves another 7.5 h (€262) a month beyond the simpler change

The error shares and the correction time are the scenario's assumptions, which we measure on cases not used for training. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat.

The comparison before the decision
  • Cases for assessment kept apart from training examples
  • The same set for the current solution, the simpler change and the new model
  • Decisions by the people who correct the results today
  • Errors counted separately for each type of mistake

Where to start

In the free process review we choose one process and 20 to 100 cases the team has already handled. We compare the simpler change with the adapted model on cases the model has not seen, and within 2 working days you get a written summary with a price. We adapt models as part of private LLMs, and build the app as an AI app.

How we count the payback: product feedback

We run the same count for your team in the free process review.

€1,675

a month for preparing 12 management reports

Payback: 2.1 mo.

4 hours to prepare a management report and checking in 15% of the old time are our assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat, for companies with 10 or more employees. Model cost: checking the commentary in our reporting system (about €0.0002) plus compiling the data (Claude Sonnet 5.5, about 30,000 + 2,000 tokens), at the ECB rate of 1.1205 USD per euro on 22 October 2026.

foap.com customer service: 95% of replies are sent automatically.

Users from several countries write to foap.com, in several languages. The system reads the entire conversation and the terms of that person, and then sends a response in that person's language. Questions about money and exceptions go to the team with a ready draft, so they have to check and send them.

We establish a prototype during a free analysis.

Data checked on October 25, 2026.

„Is my data safe?”

Yes. You choose where they go: from your company account to the model on your server.

  1. 00Employee's private account

    Customer and company data ends up in an account that the company cannot see or control. There is no data processing agreement, so it is a violation of the GDPR. When an employee leaves, the chat history goes with them.

  2. 01ChatGPT or Claude corporate account

    The provider does not use your data to train models. A copy of the queries remains in his logs for up to 30 days.

  3. 02API with zero retention (ZDR)

    The provider processes the request and does not save anything. It requires his consent, we prepare the application together.

  4. 03Processing in the EU

    Queries are counted and stored in Europe: OpenAI in the EU region, Claude via clouds with the EU region.

  5. 04Model at your place

    The open model runs on your server or in your cloud in the EU. The data does not go outside the company.

What we do with every implementation

  • Confidentiality agreement and data processing agreement before we receive any data.
  • You choose the cases for the prototype and we anonymize them upon request.
  • The data stays in the EU and we delete it after the test.
  • Corporate accounts with an administrator on your side.

When data cannot leave the company

The open model runs on your server or in your cloud in the EU. To choose from:

PLLUM
Polish model, HIVE consortium commissioned by the Ministry of Digitization
Qwen
Alibaba
GLM
Zhipu AI
DeepSeek

Do you have a lot of your own data? We will fine-tune the small model.

  1. 1 Your examples
  2. 2 tuning
  3. 3 test on new cases
  4. 4 model at your place

When you have thousands of similar emails, documents or reports, we teach a small open model based on your examples. It works for you, responds quickly and costs less to maintain than a large model. We measure quality on issues that the model has not seen while learning.

Przemysław and Piotr did it in large programming and consulting companies. Artem did it before and does it today at Syntalith. It's about models on your own infrastructure, tuning and quality measurement.

Questions

  • How does AI analyse feedback on B2B products?

    It assigns parts of a comment to topics, for example the manual or setting up the machine, and keeps both experiences from one sentence.

  • When does your own feedback model make sense?

    When a ready topic tool regularly merges distinctions that matter for the product, and the team has checked examples of correct assignments.

  • How much does fine-tuning a model cost?

    An AI app at Syntalith costs from €3,000 net, and we price adapting the model after comparing it with a simpler change on cases the model has not seen. In the scenario, fine-tuning saves another 7.5 hours a month beyond what the ready topic tool gives.
