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 all excerpts, and stays entirely on your machine.

The workflow

Five steps to a complete analysis

A five-step wizard handles method selection, configuration, model choice, data upload, and cost estimation. The pipeline then 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.

Methods

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

Each method follows published methodological commitments. The wizard records your choices verbatim, so you have a record for the methods section.

Why QualiLens

What makes QualiLens different

Established CAQDAS platforms host your data on their servers or require per-seat licenses. QualiLens is open source, runs locally, and replaces manual coding with auditable LLM-assisted coding behind researcher-controlled checkpoints.

Researcher-led checkpoints

The pipeline pauses at each analytic decision point. Your edits are final and are not overwritten by later automated stages.

Provenance on all excerpts

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

Full audit trail

All stage boundaries, model calls, and researcher decisions are logged. The report appendix reproduces this trail for reviewers.

Runs locally

No QualiLens server. Your data go 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 each run, and resumable runs that don't 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 stay 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 requires a Mac with Apple silicon or a Linux computer (on Windows, WSL), Python 3.11+, and an API key from any supported provider. A single-document analysis typically costs a few cents.
