Paideias combines AI-assisted codebook generation, real-time collaborative coding, and built-in inter-coder agreement in a browser-based workspace — no licence fees, no installation, and a QDPX export path if you ever want to move a project back to ATLAS.ti.
Migrating from ATLAS.ti
Paideias exports and imports projects in the QDPX format, the open interchange standard for qualitative data analysis software. If your department or lab already has ATLAS.ti projects, you can bring your codebook and coded excerpts into Paideias without re-coding from scratch, and export back out if you ever need to. That interoperability is deliberate — Paideias is built to be the tool teams switch to, not one that locks their data in.
Frequently Asked Questions
Paideias is a browser-based ATLAS.ti alternative with AI-assisted codebook generation, real-time collaborative coding, built-in inter-coder agreement (Cohen's Kappa, Krippendorff's Alpha), and client-side AES-256-GCM encryption — free to start with no installation.
Paideias exports and imports the QDPX format, the open standard for QDA data exchange that ATLAS.ti also supports, which makes moving projects between the two tools straightforward.
Yes. Paideias calculates Cohen's Kappa and Krippendorff's Alpha automatically across coder pairs for every code in a project, and surfaces the breakdown per code so teams can resolve disagreements before they affect the whole dataset.
