AI for store data analysis: what you can trust it with
AI analytics means using language models (chat assistants and assistants built into analytics tools) to ask questions about your store's data in plain words: "why did revenue drop?", "which products earn the most?". Models prepare queries and explanations quickly, but they make mistakes with numbers, so the result has to be checked.
In plain words
AI is good at a draft: a database query, a spreadsheet formula, a short description of a chart. Accuracy is harder for it: it can skip a value in a table, add things up wrong, or miss that the data contains an error. So it makes sense to trust AI with preparation and leave verification to a person.
What the research says
- Dirty data. The RADAR benchmark (NeurIPS 2025, 2,980 table-query pairs from real data) tests whether models notice missing values, outliers and logical inconsistencies. The authors' conclusion: frontier models do well on clean tables, but quality drops sharply when such flaws appear (arXiv, 2025). Store data is usually dirty: duplicate orders, test purchases, empty fields.
- Table reading errors. An ACL 2026 paper (June 2026) shows that models make mistakes when quoting or skipping table values, even when they understand the table's structure; these errors were found in every model tested (from 1.7 to 20 billion parameters) (arXiv, 2026). This is a study of small models; it has no direct figures for the largest services.
- Complex database queries. The LLMSQL benchmark (2025) shows that on a cleaned test based on WikiSQL, DeepSeek-R1 reaches 88.40% accuracy without additional training (arXiv, 2025). This is a simple test with queries to a single table; the result does not carry over to the complex data schema of a store. There are no separate figures on accuracy with real online store data.
Assistants inside the tools themselves
GA4 has a conversational assistant, Analytics Advisor. In October 2025 Search Engine Journal reported that it had appeared for some users, while Google had not published a help page or an official announcement at that time; the scope of availability, data handling and whether it can be turned off remained unclear (SEJ, 2025). Check the current status in Google Analytics help.
What you can trust it with
Task | Trust |
|---|---|
Write a query or formula | Yes, but check the result on 2–3 rows you know |
Explain what a metric means | Yes, verify against the help docs |
Summarize a large text review | Yes, spot-check |
Calculate revenue, margin, conversion | Only through a verified system; AI can get the total wrong |
Explain the reason for a change | As a hypothesis that needs testing |
Decision on purchasing or pricing | No, only as one input |
Safety rules
- Do not upload customers' personal data (phones, addresses) to public services. See Personal data in Ukraine and GDPR.
- Ask it to show the query or the steps, and repeat the calculation by hand on a small sample.
- Clean the data first (duplicates, test orders), otherwise the model will add up the errors too.
- Fix the metric definitions (what counts as "revenue", "order") so AI and people count the same way.
- Compare the answer with a dashboard (Owner's dashboard).
Common mistakes
- Taking a confident tone for accuracy.
- Asking "why?" when the data has no field for the answer.
- Trusting an estimate of ad impact based on correlation: causes need an A/B test.
- Giving AI working data that contains customers' personal data.
FAQ
Can AI replace an analyst? Only one thing follows from the confirmed data: AI speeds up preparation, but errors in numbers happen (2025–2026 studies). The studies do not confirm replacement.
Can I ask ChatGPT about my sales? Yes, if the file has no customers' personal data and you check the result.
What should I check first? Total sums and row counts: do they match your accounting system?
