Papers, RFCs, and design docs need structure checks, linked citations, and history that survives collaboration. Canvas combines code and citation blocks with save points at review gates — so rebuttals reference exact structural change, not “the version from Tuesday.”

On working with constraints
Constraints don't fight a draft — they give it edges. The hardest part of any long document is deciding what it isn't.
Working hypothesis: the more open the canvas, the longer the first paragraph takes.

Research memos, RFCs, and design docs need more than paragraphs. Citation blocks link to sources; code blocks carry API shapes; callouts flag decisions. Structure-check skills align headings to your outline before submission.
Advisor feedback, peer review, eng sign-off — each gate gets a named snapshot. Diff against the submitted version for your rebuttal letter: which sections moved, which claims changed, which citations were added.

Write in Canvas for collaboration and AI-assisted structure; export markdown for git, static site generators, or LaTeX prep workflows. The canonical doc stays in Inkwell; exports are snapshots, not forks you lose track of.
Canvas — rebuttals need structural diffs against the submitted baseline — not “the version from Tuesday” buried in autosave history.
The three primitives that do the heavy lifting in this workflow.
Extract relevant passages from PDFs and articles into linked block citations — traceable back to source material, not pasted quotes you cannot find later.
Decision records, API contracts, and eng-review diffs at block granularity — the shape eng teams use internally, with version semantics docs tools usually lack.
Save points per submission round; diff for advisor check-ins; export for journals that still want Word or LaTeX handoff.
Skills and diffs run on your draft — nothing lands until you accept it. Every accepted change can become a save point.
Advisor or peer review without losing the submitted baseline.
Citation blocks tied to sources; structure check against your outline.
Snapshot frozen; you continue editing on main or a draft line for major restructure.
Threaded feedback on the paragraph or section — not a separate email thread.
Exact structural change for your revision letter or rebuttal doc.
Migration, granularity, pricing, and feature status — the concrete questions buyers raise before they switch.
Not necessarily. Many teams write and collaborate in Canvas, then export markdown or structured content for LaTeX conversion in their existing pipeline. Canvas is the canonical collaborative doc with history — export is a handoff step, not a fork you lose.
Digest quality depends on source text extraction. Clean PDFs yield linked block citations; scanned or garbled PDFs may need manual cleanup after ingest. Treat digest as assisted extraction, not automatic bibliography generation.
Real-time co-authoring and team workspaces are Team-plan features. Save points and diffs work for solo researchers on Pro; multi-author labs should plan on Team for presence and shared workspaces.
Diffs operate at block and heading level — a moved section, a rewritten paragraph block, a changed code fence — not character-level noise across the whole document. That matches how reviewers think about structural feedback.
