The Short Answer
Thematic is a well-regarded AI feedback-analytics platform. Point it at a pile of existing unstructured feedback - survey verbatims, support tickets, app reviews, call transcripts, CRM notes - and it surfaces themes without predefined categories and quantifies what matters. Independent reviews credit it with 80-90% theme accuracy depending on the dataset. (Thematic) If you have a feedback backlog and need to make sense of it, Thematic is a serious tool.
But notice the precondition: data you already have. Thematic is an analysis-only layer. It does not talk to your customers, it does not ask follow-up questions, and it cannot capture the context that was never written down. Its output is only as deep as the raw feedback you feed it - and most raw feedback is shallow, one-line, and unprobed.
Koji owns the entire loop. Its AI voice interviewer collects the conversations - probing each answer in real time - and then automatically codes them into themes with a one-click report. You are not analyzing thin survey scraps after the fact; you are generating rich, purpose-built qualitative data and getting the analysis for free in the same workflow.
Short version: Thematic makes sense of feedback you already have. Koji generates better feedback and makes sense of it too. For teams that want depth rather than dashboards of existing noise, Koji is the more complete, AI-native choice.
Why "analyze what you have" hits a ceiling
The fundamental limit of any analytics-only tool is the garbage-in problem. If your inputs are NPS comments and one-star reviews, even perfect analysis yields shallow themes: "shipping slow," "too expensive," "confusing UI." Those are symptoms, not causes - and acting on symptoms wastes roadmaps.
This matters because the cost of misreading customers is enormous. PwC's 2025 research estimates poor experience costs U.S. businesses about $1.6 trillion a year, with 73% of companies underestimating their true churn. (PwC 2025) And "too expensive" is the most over-reported symptom of all - in reality, price is rarely the real reason customers churn. The only way to get past the symptom is to probe - to ask the follow-up question in the moment. Analytics tools cannot do that. An AI interviewer can.
Koji vs Thematic: head-to-head
| Koji | Thematic | |
|---|---|---|
| Collects data | Yes - AI voice & text interviews | No - analyzes data you import |
| Probes follow-ups | Yes, in real time | N/A |
| Analyzes feedback | Yes - automatic thematic coding | Yes - its core strength |
| Data depth | Rich, probed conversations | Limited to existing (often thin) feedback |
| Structured metrics | NPS, CSAT + 6 question types | Quantifies themes from text |
| Setup | ~30 min, self-serve | Integrate sources, configure |
| Pricing | From EUR 29/mo, 10 free credits | Enterprise annual contracts |
| Best for | End-to-end research (collect + analyze) | Analyzing large existing feedback corpora |
1. Collection is the missing half
This is the whole game. Thematic is downstream of data collection - it inherits whatever depth your existing channels happened to capture. Koji is the collection step, and it is built to capture depth: when a customer says "the reporting felt limited," Koji's AI interviewer asks which report, what decision they were trying to make, and what would have unblocked them - automatically. The dataset Koji analyzes is one Thematic could never receive, because the probing that created it never happens in static feedback.
2. Analysis: you still get it - automatically
Choosing Koji does not mean giving up the analytics Thematic is known for. Koji performs two-pass thematic coding: an open/descriptive first pass grounded in verbatim quotes, then an axial pass that clusters near-duplicate themes into a clean codebook across every interview - and assembles a shareable report. It is the analysis layer and the collection layer in one. (See how Koji analyzes open-ended responses and our thematic analysis guide; if you are evaluating analysis-only tools, our best AI thematic analysis tools guide compares the category.)
3. Structured + qualitative in one pass
Thematic quantifies themes from text, but it cannot run a structured NPS or CSAT question and then probe the reason behind the score. Koji supports six structured question types - open-ended, scale, single-choice, multiple-choice, ranking, yes/no - so a single Koji study captures the number and the narrative, with both flowing into the same report.
4. Speed, cost, and access
Thematic is an enterprise product with annual contracts and source-integration setup. Koji is self-serve: live in ~30 minutes, EUR 29/month (Insights) or EUR 79/month (Interviews), 10 free credits to start, transparent credit costs (text = 1, voice = 3), and a quality gate so only substantive conversations are billed. You can go from idea to analyzed interviews in an afternoon.
5. Bias and consistency
Imported feedback carries every response bias and leading-question artifact baked into how it was originally collected. Koji's AI interviewer asks every participant neutrally and identically, producing cleaner, more comparable qualitative data than the messy corpora analytics tools typically inherit.
When Thematic is the right call
Thematic is genuinely good at its job. Choose it if:
- You sit on a large backlog of existing feedback (tickets, reviews, verbatims) and need to quantify it.
- You want a dedicated analytics layer on top of feedback channels you will keep running.
- Your collection is already solved and your gap is purely making sense of volume.
In that scenario, an analysis-only specialist earns its place - and you can even pair it with Koji for the conversations your existing channels miss.
When Koji wins
Choose Koji if you need new depth, not just analysis of old noise:
- Discovery & validation: test problems, features, and messaging with real, probed customer voices.
- Churn & win/loss root-cause: interview the people themselves instead of mining their one-line complaints.
- Pricing research: uncover willingness-to-pay through conversation, not guesswork.
- Continuous discovery at scale: run weekly interviews without staffing every session.
- Lean teams that want collection + analysis in one self-serve tool, not two enterprise contracts.
Koji delivers 10x faster insights, no research expertise required, and the full path from question to insight in hours, not weeks.
The bottom line
Thematic is an excellent analysis tool - but analysis is only half the loop, and it is the second half. Whatever Thematic surfaces is capped by the depth of the feedback you already collected, which is usually thin. Koji closes the loop: it collects rich, probed conversations and analyzes them automatically, so you are not reverse-engineering insight from one-line reviews - you are getting it straight from the source.
If your problem is "we have too much shallow feedback and cannot make sense of it," Thematic helps. If your problem is "our feedback is too shallow to act on," that is a collection problem - and Koji is the AI-native platform built to solve it end to end.
