Make a better
research question.
Practical ideas for connecting sources. These are workflows to explore, not pre-computed conclusions.
Explain a price disagreement
Compare a spot-metal quote, an explicit futures contract and any currency conversion. Check units, contract identity, provider and source-time basis before describing a difference as a market move.
Follow the manual →Trace a shipping disruption into company research
Start with source-backed port or corridor evidence, inspect time/geography, then review the relevant company exposure and assumptions. A spatial match is a candidate relationship, not proof of loss.
Follow the manual →Find what actually changed in a source
Choose one source or instrument in Data History, compare retained versions, and separate observation date from capture date. Distinguish a corrected value, a newly captured older record and a new observation.
Follow the manual →Compare a historical narrative with its map sources
Use Ancient Map to compare records with different publication and depicted dates. Preserve projection/alignment limitations and source licences rather than treating the overlays as ground truth.

Are the data examples live?
Prices and observations are fetched from Watchtower sources, not sample numbers. Cryptocurrency cards show source-dated USD market snapshots; ECB currency cards are dated reference fixings, with derived cross-rates labelled. The data refreshes in the background. Each source has its own cadence. Source observation dates, partial coverage and last-known snapshots are visible in the evidence panel. Reference imagery is clearly labelled.
Can I save my research?
Pro includes saved investigations, reports, alerts and exports, so you can return to an idea and keep the supporting evidence together.
What does Pro include?
Pro provides the research workspace, including advanced views, saved investigations, reports, alerts, source-linked exports and historical research. Licensed sources, optional model requests and administrator previews retain their separate requirements. Subscriptions renew monthly or yearly through PayPal.
