Four plans

Start where your study is.

Sotto is sold in four plans, and each one includes everything in the plans below it. Move up when the work moves on, and move back down whenever you want. What you have already made stays yours to read and to export at every plan, including the free one.

Sotto Stacks

Free

Your whole research library, searchable, on your own computer. Free, no card, no expiration.

Sotto Scope

$9.99 / month

Design the study. Methodology, research questions, instruments, IRB materials and field notes, all on an ordinary laptop.

Sotto Sense

$19.99 / month

Transcribe and code your interviews on your own computer. Needs a machine that can run a language model.

Sotto Solo

$29.99 / month

The complete qualitative workflow for one researcher, from protocol to written findings. Needs a machine that can run a language model.

Every plan keeps your research data on your own computer.

The boundary

You decide what, if anything, leaves.

Participant data is analyzed on your own computer. Writing help and literature review are the two places where anything can cross, and Sotto shows you the exact text first and sends nothing until you approve it.

Inside, on your machine

Everything your participants said.

✓Recordings and transcription
✓Coding and thematic analysis
✓Memos, field notes, IRB protocol
✓Your whole searchable library
You choose
Outside, only if you send it

Two places an AI model is involved.

→Writing help on a passage you send
→Literature review across published sources
·Nothing else, and nothing by default
·License checks send a key, never your data

Start free. Move up when the work does.

Sotto Stacks needs no payment card and uses the same installer as every paid plan, so you can find out whether Sotto runs on your computer before you pay.
