Qualitative Coding Tag Hub — Free Text-Segment Tagger

This tool supports the first pass of qualitative coding: you paste a text segment from an interview or open response, assign it a code (a short label capturing what the segment is about), and build a coded set with live counts per code. Coding turns pages of raw text into an organized structure where patterns can be seen: which codes recur, which appear once, and which segments share a code. The tool exports the coded set as JSON for use in other software. It does not code for you — the judgment of what a segment means stays human, which is exactly as it should be in qualitative research.

How to use it

Paste a text segment.
Type a short code for it, using consistent wording.
Click Add tagged segment.
Repeat for every segment you code.
Watch the counts: recurring codes are candidate themes.
Click Export JSON to save the coded set.

Worked example

Coding ten interview passages about starting a new job, you tag “I felt lost on my first day because nobody explained the system” as onboarding-gap, and three similar passages get the same code. Two passages about helpful colleagues become peer-support. The counts table now shows onboarding-gap 4, peer-support 2, and a handful of singletons. That structure is the beginning of a theme: newcomers’ early experience is shaped less by formal training than by whether anyone explains the unwritten system — a finding that emerged from the codes, not from counting words.

Honest limits

This hub stores segments only while the page is open; closing the page loses the coded set unless you exported the JSON, so export often. It codes segments you paste, not whole transcripts automatically, and it offers no inter-coder agreement measurement — for that, use the Inter-Rater Reliability Calculator with a second coder’s independent codes. Codes are only as good as their definitions: without a codebook (one sentence per code, with an example and a counter-example), two coders will use the same label for different things and the counts will mislead.

Who it is for

This tool is for students learning qualitative coding, researchers doing a first open-coding pass, and small teams who want a lightweight way to organize segments before moving to dedicated software. It is a starting bench, not a full analysis environment: when codes number in the hundreds, graduate to dedicated qualitative software.

Going further

Write the codebook as you code, not after. Each time you create a code, add one sentence defining it, one example segment that fits, and one that nearly fits but does not — the near-miss is what keeps future coding consistent. Review singletons at the end: a code used once may be a genuinely unique insight worth keeping, or a label that should merge into a sibling code. And code in passes: a first pass with broad descriptive codes, a second pass grouping codes into themes, and a final pass checking that every segment still fits its code after the themes changed. Coding is analysis, not filing, and the hub is most useful when you treat each tagging decision as a small analytic judgment rather than a clerical one. Keep a memo for each code as it evolves: when you created it, what made you split it from a sibling, and which segment forced a definition change. Those memos become the audit trail of your analysis and often the first draft of your findings section, because they record not just what you coded but why you saw it that way at that moment. Months later, when a reviewer asks why a theme emerged, the memo answers with evidence instead of reconstruction. Qualitative rigour lives in such records far more than in any count.
