DATA TO EVIDENCE
Your research,
in one place.
Upload a dataset, explore shared samples and connect your assistant to private analysis.
Access is by invitation.
YOUR WORKSPACE
Your data, projects and saved evidence. Develop the analysis in Claude or Codex.
Administrator review is recorded for the selected workspace.
Add a dataset
CSV, Excel (.xlsx), Parquet, JSON or Stata (.dta), up to 200 MB. Uploads and results stay private to this workspace.
Private library
Verified results
Revisit your saved findings, read the report, or download the supporting files. Opening a report does not rerun the analysis.
Research projects
Group datasets, questions, notes and saved reports without moving underlying data.
Your research team
Keep a shared study with its own members and data permissions. Your private workspace stays separate.
Prepare study data
Owners copy a private dataset into this study as an immutable snapshot. Choose one of your datasets, or paste the reference from Datasets → Copy dataset context. An additional version copies the same approved bytes under a separate identity; it does not transform or ingest data. Coauthors can inspect a known version and copy its context. Reviewers cannot prepare data.
Transform and register
Choose shared snapshots, build a recipe step by step, preview it, then apply it and register the resulting dataset. Repeating the same recipe reuses its immutable output. Missing values are never filled automatically.
1. Study sources
Pick snapshots already shared in this study. Each hash is filled in automatically. Add a second source only to join it.
2. Recipe steps
3. Dataset roles for registration
Column choices come from the previewed output when available, otherwise from the columns the recipe is expected to produce.
The exact documents that preview and apply send. Edits here replace the guided choices when you return to them or preview.
Continue in your research client
Copy the verified prepared dataset context, then continue registration and analysis in Claude or Codex. That client records the analysis-specific approvals.
Members and data access
Coauthors prepare and analyse. Reviewers inspect approved evidence. Raw data access is a separate, explicit grant.
Recent study activity
Study setup, membership and data preparation events. Analysis conversations remain in Claude or Codex.
Approved evidence
Reports explicitly approved for a named study member. Downloads recheck access and saved-report integrity. These approvals do not grant raw data access.
Published analyses
Open saved research state, revision history and results. Continue the research conversation in Claude or Codex.
Shared sample library
Read-only examples for exploration.
Connect Claude or Codex
Codex and Claude setup
Use the pre-registered client ID and complete OAuth in your client. Never paste a password or token into chat.
Full connection guideRemembered MCP connections last up to 30 days, with a seven-day idle limit. Your workspace browser session has its own eight-hour limit.
Reconnect an expired assistant connection
In Codex, run codex mcp login prolug and complete sign-in.
In Claude, open this connector in Settings and choose Reconnect.
Then start a new conversation and ask the assistant to check DiD-Acto's tools.
Your saved datasets and reports remain in your workspace.
Begin a careful analysis
Copy this guide to help your assistant inspect data, ask useful questions, suggest alternatives, explain uncertainty, and keep the tool's assessment beside every result.
