I never really felt like I belonged in that space — it was always clear that the rules were written by and for people who didn't look like me. When I started speaking up, things shifted. Not immediately, but gradually the dynamic changed.

My sense of identity had always been tied to place. Moving disrupted something fundamental — not just logistically but psychologically.

Everything you need

From raw data to
publishable insight

Codex covers the full qualitative workflow — data import, iterative coding, rich queries, and AI-powered synthesis.

Capture

Multi-format Import

PDF, DOCX, PPTX, TXT, Markdown, CSV — drag and drop into your workspace.

Audio Transcription

Whisper-powered transcription with automatic speaker-turn detection.

Web Fetching

Paste any URL and Codex extracts clean, readable content automatically.

Image & OCR

Import images; AI describes visual content and OCR surfaces embedded text.

Code

Manual Coding

Highlight any text, assign codes with color. Overlapping codes, hierarchies, and ⌘1–9 shortcuts.

AI-Assisted Coding

Inductive, deductive, and hybrid approaches. AI suggests codes for selections or entire sources.

Coverage Stripes

Visual sidebar stripes show coded regions at a glance. Coverage % per source.

Annotations & Memos

Inline sticky notes, three memo types: project, source-linked, and code-linked.

Analyse

Word Frequency

Top-50 word frequency with stopword filtering and visual frequency bars.

Matrix Coding Query

Codes × Sources heatmap. See at a glance where themes concentrate.

Co-occurrence Analysis

Detect which code pairs appear together most — and in which sources.

Word Clouds

Per-code vocabulary clouds and project-wide word clouds, size-weighted.

AI IntelligencePro

AI Chat Assistant

Ask natural-language questions about your data. Claude reads all sources, codes, and memos.

Report Generation

AI writes a methods section, findings, and abstract — academic-ready, codebook-informed.

Interview Guide

Generate follow-up questions based on emerging codes. Thematic grouping with facilitator notes.

Intercoder Reliability

Compare two coders, calculate agreement ratios, and let AI mediate conflicts.

CollaborateTeam

Real-time Team Sync

S3-backed project sync with 30-second polling and focus-triggered updates.

Longitudinal Analysis

Trace how themes evolve across sources over time. Identify turning points.

Snapshots & Restore

Version history for your project. One click to restore any prior state.

Export & Share

JSON/CSV export. Shareable public read-only links — no login needed for collaborators.
