Summarize a collection

Summarizer produces one summary per document, configurable length and tone, downloadable and savable.

Summarizer runs the same summarization task across every source in a dataset. One summary per document, the way you specify, all downloadable in a single run.

What you get

  • One summary per source in the dataset.
  • Each summary uses the length and tone you picked.
  • Downloadable individually (as PDF or markdown) or all at once as a ZIP.
  • Optionally saved into your workspace as notes (one note per source) for further editing in Co-work.

Run it

  1. 1

    Build the dataset: pick a label, multi-select on the documents page, or use Smart Search to find the right set.

  2. 2

    Open the workflow runner and pick Summarizer.

  3. 3

    Set the inputs (see below).

  4. 4

    Click Run. The workflow dispatches a sub-worker per source and persists the results to a durable record. You can leave the page; the run continues in the background.

Inputs

  • Length: brief (a few sentences), medium (a paragraph or two), detailed (multi-section). Brief is faster and cheaper; detailed catches more nuance.
  • Tone: neutral, formal, conversational, technical. Pick what fits the audience.
  • Format: narrative prose or bulleted. Bulleted is easier to skim; narrative reads better.
  • Custom instructions: optional free-form guidance ("focus on financial risks", "ignore boilerplate sections", "include section page numbers").

The custom-instructions field is the most under-used and most useful input. A short steer ("emphasize renewal terms and termination clauses") changes the summaries noticeably.

When summaries land

Each per-source summary lands as it completes. You can open partial results while later sources are still running.

If the dataset is large, the workflow respects your plan's prompt fair-use limits. Workflow runs are credit-metered; see How credits work.

After the run

  • Save as notes: turns the summaries into editable notes in your workspace, useful when you want to refine some of them in Co-work.
  • Download: pull a ZIP of all summaries, or grab individual PDFs.
  • Open the run record: the workflow lives in your workspace's runs list; re-open it any time.

Common patterns

  • Onboarding a stack of contracts: Summarizer with length: medium, format: bulleted, and an instruction like "focus on parties, term, renewal, termination, and governing law."
  • Triaging a research dump: Summarizer with length: brief to find the few papers worth reading in full.
  • Briefing for a meeting: Summarizer with format: bulleted and "limit to facts the attendees won't already know."
