Agentic Index

Parachute vs Spellbook (2026)

Parachute and Spellbook help lawyers draft and review contracts to the firm's own standards, and they differ in where the work happens. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.

Spellbook lives in Microsoft Word, where it reviews and redlines, drafts from saved libraries and precedents and applies playbooks, while Spellbook Associate takes a goal across a set of documents and revises many at once, pulling files from iManage and OneDrive, on OpenAI and Anthropic models with SOC 2 Type II. Parachute is a full workspace for firms of 1 to 200 lawyers, with matters, precedent drafting, five stage contract review, tabular review, AI actions in Clio and Smokeball, a notetaker, a daily briefing and one click expert verification by a lawyer, plus its own Word add in. Transactional work that stays in Word, with revisions across many documents, is Spellbook's strength. An all in one practice workspace with lawyer sign off is Parachute's.

This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Parachute and Spellbook are each graded against the same 14 capability Agentic Index taxonomy, from the vendor's own public materials under the Agentic Index verification standard, alongside 1,006 researched vendors.

Choose Parachute if

  • Matter work, meetings, email and drafting should sit in one workspace.
  • A stack of contracts should be compared side by side in a grid, with a risk flag and a citation in every cell.
  • The AI should act in Clio or Smokeball when a lawyer asks.
  • Any document should go to a lawyer for verification before it goes out.
  • Answers should cite the Australian Act and section they rest on.

Choose Spellbook if

  • Your lawyers live in Microsoft Word and want the AI there.
  • One instruction should revise terms and party details across a whole document set.
  • Playbooks should encode your negotiation positions for every review.
  • SOC 2 Type II and sign in through your own Microsoft tenant are requirements.
