A workspace that keeps claims, source passages, and review decisions connected as an argument changes.

Trace a claim
Add sources. Connect passages to claims. Review supporting evidence and counterevidence, then export the approved research record.
Revising a claim preserves its history and returns carried evidence to draft for renewed review. Source metadata, a precise locator, and human approval are required for exported evidence.
Your workspace
Explore the example or create a private workspace without an external account. A recovery key lets you return on another device.
Optional Jev review
Jev can assess evidence against a claim, compare claims, and examine changed passages. You preview the text before sending it. Suggestions stay separate from research decisions and cannot approve evidence.
The workspace works without Jev. Optional checks use the visitor’s own TypeSafe connection, with a daily review limit and a disconnect control. My personal account is not shared.
