Use case

Keep every claim connected to its source

SpacebarX gives sources, evidence, synthesis and next questions one structured home. Build the argument in a tree where the supporting context is always one branch away.

Start a research workspace

The claim is a child of the paper that licenses it. Collapse it and the evidence chain is four lines.

Make the argument visible as you build it

Use one outline for the question, sources, claims and synthesis. Every claim can carry the note, quote and source context that supports it—without scattering the work across separate documents.

Keep evidence in context

Put the source note directly beneath the claim it supports.

See gaps early

Search and saved searches reveal unfinished synthesis, missing evidence and open questions.

Preserve the trail

Version history and local-first storage keep the research record under your control.

Build the research tree

Start with the question
The document is named for what you are trying to answer, not for the literature you happen to have collected.
Add sources, claims and synthesis as branches
One item per paper, with the citation and locator in its note, so a claim can never drift away from the page it rests on.
Mirror evidence when one source supports more than one claim
It stays a single item, edited from either place — no second copy to keep honest.
