Evidano is an AI-powered qualitative data analysis platform that converts transcripts, artifacts, and survey rows into thematic, cadence, and cross-segment analyses. Anthropic’s June 26, 2026 Economic Index report "Cadences" maps hourly and daily patterns of Claude usage and links them to a paired survey, showing that 93% of conversations produce artifacts and a linked sample of ~9, 700 respondents reports rising expectations about AI. This post shows how to convert Anthropic’s public findings into reproducible, segmentable qualitative analyses using Evidano, from ingest to thematic reports and cross-segment comparisons in hours not weeks, and links to the original report at Anthropic.
Key Takeaways
Anthropic’s "Cadences" demonstrates that combining hourly usage logs, artifact labels, and a linked ~9, 700-respondent survey reveals temporal patterns, deliverable types, and rising expectations about AI; 93% of Claude conversations produce artifacts and a tax-related spike reached 8× on April 14, 2026. Evidano ingests transcripts, metadata, and survey rows to reproduce artifact and cadence analyses and cross-segment comparisons quickly.
- Anthropic’s June 26, 2026 report links hourly-sampled conversations to a privacy-preserving survey of ~9, 700 respondents, enabling behavior-to-attitude mapping.
- Ninety-three percent of Claude conversations produce artifacts, so treat artifacts as first-class qualitative units when coding and comparing cohorts.
- Event spikes can be large and time-specific, for example an 8× spike in tax requests on April 14, 2026, which underscores the value of timestamped cadence analysis.
- Evidano supports ingesting transcripts and survey CSVs, training or importing artifact taxonomies, and running cross-segment and cadence analyses in a single project.
Fast take + source
Anthropic (June 26, 2026) upgraded their Economic Index to sample conversations hourly, add a classifier for outputs, and link usage logs to a survey, reporting that 93% of Claude conversations produce an artifact and that users’ expectations about AI are rising.
- Why this matters: the report combines behavioral logs (what people do) with attitudinal survey data (how people feel), the multimodal inputs qualitative teams need for policy, UX, and product decisions.
- What you’ll get from this post: practical ways to reproduce these linkages with Evidano, plus a short workflow to move from raw transcripts and survey rows to themes, cross-segment comparisons, and stakeholder-ready visuals.

What happened, research methods summarized
Anthropic combined telemetry and a linked online survey to produce the Cadences report and trained classifiers to label conversation purpose, artifact type, and autonomy metrics.
Anthropic combined telemetry (hourly sampled conversations across chat, Cowork, Claude Code, and a 1P API) with a linked online survey launched April 2026, trained classifiers to label conversation purpose (work, personal, coursework), artifact type (about 30+ categories), and reading-level and autonomy (1–5), and used privacy-preserving matching to exclude respondents with fewer than five sessions, yielding ~9, 700 respondents for analysis.
- Data types: chat transcripts, metadata (timestamps, surface), classifier labels, and survey rows.
- Analytic highlights: cadence analysis (hourly/daily), artifact distribution (explanations, documents, code), autonomy metrics, token consumption correlated with wage proxies, and attitudinal measures from the survey.
Implications for qualitative researchers and UX teams
1) Treat artifacts as first-class qualitative units
Treat artifacts as first-class qualitative units because Anthropic finds 93% of conversations produce artifacts and many of those are explanations (17%) or documents (15%).
For qualitative research, codebooks and thematic coding should include artifact type as a primary field so teams can compare not just topics but deliverable forms across user cohorts.
2) Use cadence to triangulate intent
Use cadence to triangulate intent because hourly patterns sharpen interpretation of motivations, for example news at 7 a.m., recipes at 6 p.m., and sleep advice around 5 a.m.
When you see a spike in a cluster, link timestamps to qualitative notes or open-text survey answers to capture context around the observed behavior.
3) Link behavior to perception at the respondent level
Link behavior to perception at the respondent level because Anthropic shows people who delegate more are more optimistic about pay and job prospects.
Your qualitative survey should capture both usage logs and open-ended rationale to explain why delegation aligns with optimism or worry.
4) Watch for sample bias
Report and adjust for sample bias because the survey respondents skew toward Computer & Mathematical (≈30%) and Management (23%).
Always report respondent composition and weight or stratify analyses when generalizing beyond heavy users.
Do more, faster with Evidano, mapped to this use case
Problem: Multimodal inputs (transcripts + survey rows + metadata)
Ingest transcripts and survey CSVs together to preserve timestamps and session IDs and run combined thematic and frequency analyses so artifacts, cadences, and survey responses are linkable in one project.
Solution in Evidano: upload files; preserve timestamps and session IDs; and run a combined thematic and frequency analysis so artifacts, cadences, and survey responses are linkable in one project.
Problem: Need consistent artifact coding across 30+ types
Train or import a classifier to standardize artifact labels so you can compare artifact distributions across cohorts.
Solution in Evidano: import Anthropic-style codebook or train a custom classifier, then run AI-assisted coding to label artifact types and purposes and export disagreements for quick human review.
Problem: Compare segments (e.g., automation share, occupation, gender)
Run cross-segment analyses and hierarchical code trees to surface frequency tables, co-occurrence networks, and side-by-side quote buckets for decision-makers.
Solution in Evidano: run cross-segment analyses and hierarchical code trees; export frequency tables, co-occurrence networks, and quote buckets per segment.
Problem: Reproduce cadence analyses (hourly/daily) and event spikes
Filter by timestamp to generate hourly heatmaps and to tag event windows so you can surface representative quotes and artifacts from those windows, for example the April 14 tax spike.
Solution in Evidano: filter by local timestamp to build hourly/daily heatmaps and to tag event windows and surface representative quotes and artifacts from those windows.
Security & compliance
Use end-to-end encryption, PII redaction, and data-use guarantees when working with sensitive qualitative research to match privacy-preserving approaches.
Evidano encrypts data, supports PII redaction, and does not train third-party models on customer data, making it suitable for sensitive qualitative research similar to Anthropic’s privacy-preserving approach.
Quick workflow: reproduce Cadences-style analyses in 7 steps
Collect transcripts, metadata, and survey rows with respondent IDs to start the Cadences-style workflow.
1) Collect: export transcripts (chat/agent logs), metadata (timestamps, surface), and survey CSVs with respondent IDs.
2) Ingest to Evidano: upload files; enable custom dictionary and PII redaction if needed.
3) Auto-label: run artifact classifier and purpose (work/personal) and autonomy scoring, then review low-confidence labels.
4) Thematic coding: run AI-assisted open-coding, collapse into themes, and validate with purposive samples.
5) Cadence analysis: filter by local timestamp to build hourly/daily heatmaps and tag external events (for example, filing deadlines).
6) Cross-segment analysis: compare automation share, occupation, gender, and sentiment; export quote lists per segment.
7) Report: generate visualizations such as word clouds, co-occurrence networks, and hierarchical code trees and prepare stakeholder-ready summaries.

FAQ: AI-enabled qualitative research
What are the core insights of Anthropic’s Cadences report?
The core insights are that hourly-sampled conversations linked to a survey reveal temporal patterns, artifact prevalence, and shifting expectations about AI.
Anthropic reports that 93% of conversations produce artifacts, a linked survey of ~9, 700 respondents shows rising expectations about AI, and event-driven spikes such as the 8× tax spike on April 14, 2026, illustrate strong temporal effects.
How can researchers reproduce artifact and cadence analyses?
Researchers can reproduce artifact and cadence analyses by ingesting transcripts and survey rows with timestamps and respondent IDs, running classifiers, and filtering by time windows.
Follow the seven-step workflow: collect transcripts and survey CSVs, ingest to Evidano, auto-label artifacts and purposes, run thematic coding, build hourly/daily heatmaps, compare segments, and generate report visuals.
Which data types are necessary for Cadences-style studies?
Necessary data types include chat transcripts, metadata with timestamps and surface, classifier labels, and linked survey rows with respondent-level identifiers.
Anthropic used chat transcripts, metadata, classifier labels for purpose and artifact type, and a privacy-preserving linked survey to enable behavior-to-attitude mapping.
How should teams handle sample bias in these linked datasets?
Teams should report respondent composition and apply weighting or stratification when generalizing beyond heavy users to handle sample bias.
The Anthropic survey skews toward Computer & Mathematical (≈30%) and Management (23%), so report composition and apply weights or stratify analyses when necessary.
