Do you want to compare groups, or code every response?

To see what sets one segment apart from another, comparative analysis works. To cross codes with the rest of the questionnaire, you need every response coded and back in your data.

What languages are your responses in?

According to its help center, Relative Insight analyzes words and phrases in 13 languages, but runs the full analysis only in English, French, German and Spanish, and compared data must be in the same language. Always ask about yours.

Do you measure in waves and need the same codebook in all of them?

Ask to see how the codebook carries from one wave to the next, on your own data.

Where is your data processed?

Relative Insight states ISO 27001 certification at its Lancaster and London offices; we did not find on its site which AI models it uses. Survey Coder uses Claude models, by Anthropic. Always ask.

Do you pay a subscription or for what you code?

With occasional studies or uneven volume, the pricing model changes the real cost a lot.

Comparison

Survey Coder vs Relative Insight

Relative Insight is a customer intelligence platform built on comparative text analysis: it shows what sets one group apart from another in surveys, calls, tickets, reviews or social media. Survey Coder is built for a different job: coding your survey open ends and returning them to your data and your tables.

Where they are alike

Both analyze open-ended survey responses, such as NPS or satisfaction.
Both let the analyst define their own categories.
Both let you track themes over time.

Where they differ

Survey CoderRelative Insight

Built for

Survey CoderOpen-ended survey responses: NPS, satisfaction, concept tests, trackers.

Relative InsightComparative analysis of customer, fan and employee text: surveys, calls, CRM notes, tickets, reviews, social media and chats.

How it uses AI

Survey CoderBuilds the codebook from your responses, or applies the one you already use, and codes every response.

Relative InsightCompares datasets to show how they differ, detects topics with AI, and lets you build your own themes on top of them.

What you take away

Survey CoderThe codes as columns attached to each respondent, in your .sav or an Excel file; from a .sav, also the tab book with banner and significance.

Relative InsightDashboards, insight cards as PowerPoint or images, and CSV exports with frequencies and differences between groups.

Waves of an ongoing program

Survey CoderThe next wave inherits the same codebook automatically, so the trend is comparable.

Relative InsightIts custom themes, applied to time-stamped data, show how each theme changes over time.

How you pay

Survey CoderPer coded response, one-time purchase. Credits never expire.

Relative InsightCustom quote based on data sources, volume and licenses; no per-word or per-message charge. One-year minimum contract. Free trial, no credit card.

What we say about Relative Insight comes from its website and help center, as of September 23, 2026.

When Relative Insight is the better fit

If you want to monitor what customers, fans or employees say across many channels continuously, and compare segments to see what sets them apart, Relative Insight is built for that. Survey Coder focuses on coding open-ended survey responses.

When Survey Coder is the better fit

If your work is a survey program — a monthly NPS, a brand tracker, concept tests — and the codes need to come back into your data as variables and end up in tables, wave after wave with the same codebook. That is what it is built for: AI does the first pass and your team puts its judgement where it's actually needed.

What one company found when it compared

A services company compared our coding of its NPS with its own, across every response. They agreed on around 96% — and when it reviewed the differences, it found several came from errors in its own coding.

A typical study of 5,000 to 8,000 comments is coded in under an hour.

Five questions that decide it

You do not need to believe either page. These questions decide it, and they apply to any vendor — including us.
