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. No vendor pays for placement and no vendor has reviewed this page. How this evidence is graded
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.

ParachuteIntegrations & Tool Calling From any chat, Parachute's AI works inside Clio Manage and Smokeball once a firm authorizes each connection. It searches and creates matters, runs conflict checks across every matter a person or company appears on, creates and updates contacts, logs billable time, adds notes, tasks and calendar events, and saves finished documents to the linked matter, and a meeting's notes and attendance time can be filed the same way. In InfoTrack, still in beta, it gathers the details for a title, company or insolvency search, asks the user to confirm and places the order on the firm's own account. NetDocuments and OneDrive feed matters, precedents and reviews and take finished work back.

SpellbookIntegrations & Tool Calling Spellbook works inside Microsoft Word and its Associate web application. Connections to iManage and OneDrive pull the customer's documents into a chat context or project, and Spellbook also connects to more than two hundred public legal databases. All of these read data in, under the customer's existing permissions. Spellbook names no action in a third party system and no framework for adding the customer's own tools.

Workflow Orchestration Ability to sequence, branch, retry, route, and combine deterministic workflow nodes with autonomous agent steps. |
||

ParachuteWorkflow Orchestration Deep analysis takes a contract through five stages in two to three minutes. It checks the document against standard requirements, extracts every party's obligations, tests it against the firm's knowledge base, rates each risk High, Medium or Low, and runs any custom stages the firm adds. Tabular review runs each column's question across every document in parallel, the AI makes large edits across a document in one pass or produces several documents from one precedent in a single request, and in chat it chains steps such as finding a Clio matter, asking which one is right and linking it. A firm cannot build multistep workflows of its own. SourceParachute, help.goparachute.ai/features/document-review and goparachute.ai/release-notes/smarter-document-editsread 2026-10-12 |

SpellbookWorkflow Orchestration Associate takes a goal, breaks it into tasks and executes them across a document set. It updates terms and party details and fixes issues across documents, reviews datarooms and financing documents, disclosure schedules and employment packages, and revises multiple documents in one action.

Triggers & Channel Coverage How agents wake up and where they work: schedules, webhooks, message events, CRM events, inbox events, chat, email, voice, and collaboration tools. |

ParachuteTriggers & Channel Coverage Work reaches Parachute without anyone opening the app. A notetaker booked ahead of a Teams, Meet or Zoom call joins on schedule, and when the meeting ends Parachute writes the file note and transcript into a new thread. An email forwarded from a firm address to a user's own Parachute inbox becomes a thread with up to 10 attachments, and the Today briefing, built when a lawyer first opens it each day, keeps adding new email that needs a reply. Lawyers also reach it from the web app, the Word add in, the desktop app and a Slack bot that answers when mentioned. Drafting and actions in practice systems still wait for a lawyer to ask.

ParachuteKnowledge Grounding & RAG Every thread draws on two knowledge bases, the organization's own, with policies, playbooks, prior advice, contracts and structured company information uploaded as PDF, DOCX, TXT or URLs, and a global one of regulations and frameworks that Parachute curates, with the firm's content taking priority. A structured library of Acts and Regulations across all nine Australian jurisdictions opens section by section, and admins choose which Acts the AI may cite and whether it searches the web, with overrides per thread. Answers carry clickable citations back to the document, the section of the Act or the web page, and conflict detection checks new drafts against the firm's existing policies.

SpellbookKnowledge Grounding & RAG Drafting and review draw on the customer's own material and on outside sources. The customer's own material covers saved libraries and precedents, playbooks that encode its standards for every later review, and document history connected from iManage and OneDrive, with citations back to the source. Outside the firm, Spellbook draws on more than two hundred public legal databases, and Compare benchmarks terms against industry standards. All of it stays available across sessions and can be queried. SourceSpellbook, spellbook.com/integrations/imanage and spellbook.com/pricingread 2026-09-06 |

Memory & State Persistence Ability to persist context across a run, conversation, workflow, user, team, or longer-term memory layer. |
||
|
ParachuteMemory & State Persistence Personal memory keeps each user's working preferences, such as a sign off, paragraph length or how advice is set apart, and applies them in chat, email drafting and documents. Parachute saves a preference when a user states one in chat and shows a notice with a link, and users can add memories, rewrite them with AI, delete them, or switch saving and applying off. Tone of voice settings hold up to three email tones and a document voice, and each matter carries standing instructions for every draft on it. Memory never holds client or matter facts, and each chat starts fresh, so earlier conversations are not recalled.

ParachuteHuman Oversight & Guardrails Any document can go to expert verification, legal or cybersecurity, priced per request. It routes to the business's connected law firm, whose lawyers claim it from a queue and review it in the editor with comments and suggestions the client sees live, or to a pool of verified professionals, and the client rates each review. AI suggestions in the editor land as tracked changes a person accepts or rejects one at a time, InfoTrack orders and Clio matter links wait for the user to confirm, and Today drafts replies that the lawyer sends from Outlook.

ParachuteSecurity, Identity & Governance Compass Assurance Services certifies Parachute to ISO/IEC 27001:2022 under certificate 8818-4353-01, covering the SaaS platform for legal research, drafting and review, and security practices follow SOC 2 controls with no SOC 2 report. Members see their own threads, Admins manage people, settings and billing and can open all work, and an Expert role handles verification at law firms. Matters are private by default and shared per person as viewer or editor, removed members lose access at once, and the Enterprise plan adds SSO and SAML, while the Word add in signs in with Microsoft 365. Each organization's data is logically isolated and encrypted in transit and at rest. SourceParachute, goparachute.ai/security and help.goparachute.ai/account/team-managementread 2026-10-12 |

AI inference runs in the United States by default. Firms that need inference to stay in Australia can have their instance switched to Australian region infrastructure on Amazon Bedrock and Google Vertex AI in Sydney, at some cost in speed or model choice, and knowledge base embeddings already run in Sydney on Azure OpenAI.

Users choose a depth instead, Paralegal at 1 credit for quick questions and light drafting, Lawyer at 3 for detailed review and research, or Senior Associate at 15 for complex analysis, or let Auto pick the mode, and the Enterprise plan adds priority model access at busy times.
