A research instrument from Data Druid Tech. New for 2026.
Field studies · qualitative + quantitative · offline-first

A research instrument worthy of the work.

Plan your instrument, collect mixed-methods data offline, then read the open responses with Margin — a research AI grounded in your own dataset. Built for the researchers, NGO M&E teams, and consultancies who actually have to make sense of what they gather.

Paid from day one — no ads, no surprises. Used in fieldwork across Nigeria & Ghana.

"The coordination between us and the Births & Deaths Registry has improved, but regional offices still operate on three different data standards. Until that's resolved, integration is more on paper than in practice."

Made for

Three audiences. One tool.

We didn't build for "everyone." We built for the people who actually have to collect qualitative + quantitative data and then make sense of it.

NGOs & M&E teams

Baseline-midline-endline surveys, programme evaluations, dialogues. Audio interviews, GPS, photos — collected offline by a roster of enumerators, analysed centrally.

Academic researchers

PhD fieldwork, faculty studies, mixed-methods theses. Versioned instruments, ethics-aware consent, CSV exports your analysis tools can open. Plus Margin to help theme open-text answers.

Consultancies

Short engagements, multiple clients, polished outputs. Branded instruments, public response links, narrative reports drafted from your data — without Excel-stitching weeks.

Capabilities

The whole loop — designed, not duct-taped.

KoboToolbox for quant. Otter for transcripts. NVivo for coding. Excel for cross-tabs. Dropbox holding it together. Fieldnote replaces that stack with one product.

Designer

Drag-build instruments with text, Likert, GPS, audio — one form, mixed methods.

Versioned automatically. Old responses stay tied to the version they were collected on. Skip logic and cohort-gated sections built in.

Collect

Offline-first PWA — install once, work for days without a signal.

Service worker caches the app shell, IndexedDB stores responses locally, sync resumes when the connection returns. Tested across 3G, EDGE, and zero-bar deployments.

Sync

Append-only, idempotent, conflict-aware.

Every response carries a client UUID. Submit it twice — Fieldnote accepts it once. No silent overwrites, no lost interviews, full audit log.

Margin · AI

An AI that reads your responses, cites the ones it quotes, and never invents data.

Margin is your in-product research analyst. Summarise sets of responses, extract themes from open text, draft narrative paragraphs — all grounded in the actual data, with citations.

ResearcherWhat concerns came up most in Q5?
MarginFood prices (12 mentions: a1b9, c3d7, f5e2…), unreliable rainfall (9 mentions), and rising school fees (6 mentions).
GIS

GPS capture built into the form — coordinates with accuracy, no separate app.

GPS points ship today. On the roadmap: polygons, lines, and map-based analysis. The map is the input control where location is the answer.

Distribute

Send public response links by email — no app install required.

For expert interviews and online surveys, paste a list of recipients and Fieldnote generates per-respondent links. Track sent, opened, submitted.

How it works

Three steps, one continuous flow.

From the moment you draft an instrument to the moment you read your final report, the data never leaves Fieldnote. Nothing gets lost in CSV land.

Design

Draft an instrument in the visual designer. Add field types, skip logic, validation. Publish it — Fieldnote freezes that version forever; future edits fork a new draft.

Collect

Enumerators install the PWA, sync once, and go offline. Or send anonymous public links by email. Either path lands in the same response table.

Analyse

Per-questionnaire insights dashboards, AI summaries via Margin, a sectioned response viewer. Export to CSV or JSON whenever you need to leave.

Meet Margin

Your research analyst — calm, exact, and never out of context.

Margin lives in the margin of your fieldnote. Ask her to summarise a hundred interviews, find the themes across regions, draft your introduction paragraph, or check whether a specific quote came from your dataset. Every claim cites the responses it came from.

Researcher
Summarise the open-text answers from the Ghana site, focusing on coordination challenges.
Margin
Three patterns emerged. (1) Coordination gaps between the NIA and Births & Deaths Registry, cited in 4 interviews (a3, b7, c2, d4). (2) Funding bottlenecks at district level, raised in 3 (b7, c2, e9). (3) Limited interoperability with civil registration — universal across 6 of 8 interviews.
