Materials
Calculators and utilities we built for our own work and kept: agreement statistics, rating-scale scorers, transcript preparation, study planning. Every one runs entirely in your browser — no account, and nothing you paste is ever uploaded.
Compute and plan inter-rater agreement: every coefficient side by side, with confidence intervals and sample sizes.
Percent agreement, Cohen's κ, weighted κ, Scott's π, Fleiss' κ, Gwet's AC1 and Krippendorff's α — computed together, so you can see where they disagree.
Open toolHow many items does a reliability substudy need? Plans N for a target kappa or ICC confidence-interval width, and shows the precision curve.
Open toolEstimate the unglamorous parts of a transcript study before you commit to them: time, cost and turnaround.
How long will an hour of audio actually take? Estimates typing time, word count, cost and turnaround across DIY, professional and AI-plus-review workflows.
Open toolItems × passes × time × wage, plus QA and setup — to a total, a cost per label, and a timeline that assumes a realistic working day.
Open toolPrepare sensitive transcripts for sharing and analysis, without the text ever leaving your browser.
Score the standard clinical instruments, with severity bands, subscale readouts and the scoring quirks each scale is known for.
Nine items to a 0–27 total with severity band, the ≥10 screening threshold, and an explicit item-9 risk flag.
Open toolSeven items to a 0–21 total with severity band and the ≥10 clinical-significance threshold.
Open toolFourteen items to a 0–56 total, with psychic and somatic anxiety split out and both competing cutoff conventions shown side by side.
Open toolSeventeen items on mixed 0–4 and 0–2 ranges, with severity band, remission flag, and a view of the scale's uneven item weighting.
Open toolTen items to a 0–60 total with Snaith bands, remission threshold, response calculation and an item-10 risk flag.
Open toolEleven items with the four double-weighted ones handled correctly, plus a subtotal that exposes the scale's signature scoring quirk.
Open toolEighteen items on either numbering (0–6 or the original 1–7), with Shafer's five factor subscores and an approximate PANSS conversion.
Open toolTranslate depression totals between the two clinician scales using the published equipercentile tables — both directions, with bands, remission and change.
Open toolExplore the category systems behind an annotation scheme, and take them away as a label set you can code with.
