Turn a quarter's worth of product reviews into a short themes report

Turns exported product reviews into a short plain-language themes report, with every claim linked back to actual review text.

How it works
The small model tags each review against a theme list — sizing, delivery, quality, price, packaging — and pulls a short supporting quote from the review text. The large model then writes a plain-language report from the tagged pile: which themes dominate, which products they cluster on, with representative quotes for each. You get a readable document instead of a star-rating average, and every claim in it links back to a real review.
Data you need
Exported reviews as text with product ID, date and rating — a CSV from Shopify, WooCommerce, Judge.me, Trustpilot or similar. You want a few hundred reviews at minimum for themes to be meaningful; a shop with forty reviews in total does not need this.
What to expect
Reliable at surfacing themes that genuinely recur, and because every claim links to quoted reviews, the report can be checked rather than trusted. The documented failure modes are omission and overgeneralisation, not invention: the report can be accurate sentence by sentence and still miss the one theme that matters. Counting is only as good as the tagging, so treat theme sizes as rough proportions rather than precise figures, and expect sarcasm and backhanded praise to be misread sometimes.
Where people stay involved
Someone who knows the products reads the report before it drives decisions. The model can rank a theme as major that a human would recognise as one vocal customer repeating themselves, and it cannot know that the sizing complaints refer to a batch you already fixed.

Which model, and what it costs to run

This job runs in bulk rather than to a waiting person, so size is not the constraint — we take the strongest independent score on sticking to the document that we may serve freely and that fits on a single card.

Hardware only, third-party prices from 2026-07. The figure excludes the KV cache, which grows with context length and how many people use it at once — sized properly in a conversation, not guessed here. Renting by the token is cheaper up front; why our customers still self-host is below.

The API is cheaper per token. Here is why our customers don't use it.

We will not pretend otherwise: renting a model by the token from a serverless API costs less per million tokens than a card we run for you. We show that price on every use-case page. What it does not include is the part a shop with a customer database actually pays for.

  1. 01

    Your data never leaves hardware you can point at

    A serverless "we don't retain your data" is a clause in a contract. Running the model on a card in Amsterdam is a fact of architecture: your catalogue, tickets and customer records are never sent to a third party at all. For a GDPR audit, that is the difference between a promise and a floor plan.

  2. 02

    The price cannot move without your say-so

    A serverless rate card is somebody else's lever. The provider can raise the price, retire the model, or change the terms, and your cost moves with it. The same model on the same card costs the same next year — you own the number.

  3. 03

    The model cannot be taken away

    Hosted APIs deprecate models on their own schedule; the one you built on can be gone in a quarter. An open-weight model on your own hardware runs for as long as you keep the lights on. No vendor can end-of-life it out from under you.

And the price gap closes with volume: past a card you keep busy — very roughly four billion tokens a month — owning is cheaper outright, even before the three reasons above.

Getting a case like this one from a conversation to production takes about two months, and you can stop at the end of any phase.
