Qualitative analysis
with AI you can audit.

QualiLens runs five established qualitative methods — from grounded theory to literature synthesis — with LLM coding that pauses for your review, keeps verbatim provenance on every excerpt, and never touches a server we control.

Five steps to a complete analysis

The wizard walks you through method selection, configuration, model choice, data upload, and cost estimation — then the pipeline runs, pausing at each checkpoint for your review.

Step 1

Choose a method

Grounded theory, thematic analysis, content analysis, framework coding, or literature synthesis.

Step 2

Configure

Set your research question, method-specific options, and any codebook or framework.

Step 3

Pick a model

Anthropic, OpenAI, Google, or Mistral — your key, your account, direct connection.

Step 4

Upload data

Drag in documents, PDFs, or recordings. Transcription runs automatically.

Step 5

Review & run

See a cost estimate, start the pipeline, and approve each checkpoint.

Five established methods

Each method follows its own epistemology. QualiLens implements distinct pipelines with method-appropriate stages, checkpoints, and figures.

Grounded Theory

Stages
Familiarization, open coding, axial coding, selective coding
Checkpoints
Code review, core category, theoretical model
Report figure
Paradigm flow model

Thematic Analysis

Stages
Familiarization, initial coding, theme construction, theme review
Checkpoints
Code review, theme refinement
Report figure
Thematic map

Content Analysis

Stages
Codebook derivation or import, systematic coding
Checkpoints
Codebook approval, frequency review
Report figure
Frequency bar chart

Framework Coding

Stages
Apply framework, chart by source, build matrix
Checkpoints
Low-confidence review, emergent codes, matrix
Report figure
Framework heatmap

Literature Synthesis

Stages
Structured extraction, cross-paper synthesis, concept matrix
Checkpoints
Extraction table, concept review
Report figure
Concept-by-paper heatmap

Built for researchers

Every method follows published methodological commitments. The wizard records your choices verbatim so your methods section writes itself.

What makes QualiLens different

Researcher-led checkpoints

The pipeline pauses at every analytic decision point. Your edits are final and are never overwritten by later automated stages.

Provenance on every excerpt

Every coded passage stores the verbatim quote and its character position. The coded-source reader draws coding over each document in place.

Full audit trail

Every stage boundary, model call, and researcher decision is logged. The report appendix reproduces this trail for reviewers.

Runs locally

No QualiLens server. Your data goes only to the AI provider you chose, over a direct API connection. Nothing is collected.

Four providers, your key

Anthropic, OpenAI, Google, and Mistral. Cost estimation before every run, and resumable runs that never re-bill finished work.

Reports and Word export

Interactive report with narrative sections, method-appropriate figures, full evidence chains, and one-click Word export.

Your data stays on your computer.

No QualiLens server, no telemetry, no analytics, no background connections. Analysis calls go directly to the provider whose key you supplied — and nowhere else.

QualiLens needs Python and an API key. A first analysis on one short document costs cents, not dollars.
