6 minute readLast reviewed August 2026

Quick answer

Use a Document for editable work, a Response for one saved assistant answer, a Checkpoint for an imported conversation package, and a Project to group related items.

How the four types differ

TypeBest forEditable?
DocumentWriting, notes, drafts, and continued workYes
ResponseOne useful assistant answer kept as capturedMake a Document copy first
CheckpointA saved conversation packageReview it; copy selected work when needed
ProjectOrganizing related itemsIt organizes items rather than replacing them

Use a Document when the work should change

Documents are for writing and revision. Add blocks, change the title, save updates, and use Download document when you need a local file.

Use a Response when the original answer matters

A Response keeps one assistant answer as captured. Choose Make copy when you want to revise it as a Document.

Use a Checkpoint for a saved conversation package

A Checkpoint keeps the imported package and its captured work together. Review it first, then copy or organize the parts you want to continue.

Use a Project to keep related work together

A Project groups Documents, Responses, and Checkpoints. It does not combine them into one record. Open the Project, find Download project, then choose Markdown, JSON, or ZIP.

A simple way to choose

  • Need to edit it? Use a Document.
  • Need to keep one answer as captured? Use a Response.
  • Need to preserve a conversation package? Use a Checkpoint.
  • Need to keep related items together? Use a Project.
