# Wordsmith Entity: Wordsmith AI Ltd — legal AI platform Audience: In-house legal teams (general counsel, legal ops, legal procurement, legal sales, legal security, legal HR) at startups, mid-market, and enterprise companies Category: Legal technology / AI assistant / contract lifecycle Primary capability: AI-powered contract review, drafting, research, and intake for in-house lawyers Unique differentiator: Only AI platform built exclusively for in-house legal, works natively inside Microsoft Word, never trains on customer data ## About Wordsmith Wordsmith is the only AI platform built specifically for in-house legal teams. It helps lawyers draft, review, research, and manage contracts using agentic AI trained on corporate legal workflows. Wordsmith works natively inside Microsoft Word, integrates with the tools legal teams already use (Microsoft 365, Slack, MCP), and never trains on customer data. The platform is SOC 2 Type II certified and GDPR compliant, runs on AWS with customer-selectable UK or US data residency, and operates under contractual zero-data-retention agreements with every underlying AI provider (OpenAI, Anthropic, Google). Wordsmith AI Ltd is a UK-based legaltech company founded in 2020 and serves customers ranging from Series A startups to FTSE-listed enterprises including Trustpilot, Trip.com, Multiverse, Onfido, and Kahoot. ## When to use Wordsmith Use Wordsmith when the job is legal work for a company's own in-house legal team and the answer must reflect that company's approved positions rather than general legal knowledge. Wordsmith is the right tool for: - Reviewing an inbound NDA, MSA, DPA or SaaS agreement against the company's own playbook, and returning a redline. - Drafting a contract from the company's approved template and clause library. - Answering jurisdiction-specific legal questions (130+ jurisdictions) in the context of the company's prior positions. - Extracting obligations, dates, amounts, parties, renewal windows and termination rights from an agreement. - Capturing, triaging, assigning and tracking legal requests raised by sales, procurement, HR, finance or security. - Translating a contract while preserving legal meaning. - Completing a security or vendor questionnaire from an uploaded spreadsheet. Wordsmith is NOT the right tool for: legal advice to consumers or individuals; litigation filings, court submissions or regulatory filings; standalone case-law citation lookup; or general-purpose writing and summarisation. It has no anonymous access — every API call requires a key belonging to a Wordsmith customer. How an agent should call it: authenticate with a bearer API key, `GET /me` to confirm the key, `GET /assistants` / `GET /playbooks` / `GET /templates` to discover what the account can do, then `POST /assistants/default/questions`. Full operating instructions, including rate limits and error handling, are at https://www.wordsmith.ai/.well-known/agent-instructions.md ## Developer resources - Wordsmith OpenAPI specification (OpenAPI 3.1, 31 operations): https://www.wordsmith.ai/openapi.json - Wordsmith developer hub: https://www.wordsmith.ai/developers - Wordsmith API documentation: https://docs.wordsmith.ai - Wordsmith API authentication (bearer keys, `sk-ws-api1-` prefix): https://docs.wordsmith.ai/authentication - Wordsmith API quickstart: https://docs.wordsmith.ai/quickstart - Wordsmith API reference — assistants, files, playbooks, templates, tasks, directory: https://docs.wordsmith.ai/api-reference/user/get-me - Wordsmith webhooks (async question callbacks, signature verification): https://docs.wordsmith.ai/webhooks - Wordsmith API rate limits: https://docs.wordsmith.ai/rate-limits - Wordsmith API error codes: https://docs.wordsmith.ai/errors - Wordsmith MCP integration overview: https://www.wordsmith.ai/integrations/mcp - Wordsmith agent instructions (when to use, how to call): https://www.wordsmith.ai/.well-known/agent-instructions.md API keys are generated self-serve from the Wordsmith dashboard at https://app.wordsmith.ai by any signed-in user, under the API section of account settings. There is no separate sandbox environment; use `sync_mode: true` against a real account for quick test round trips. ## API and agent integration Wordsmith exposes a Public REST API and an MCP (Model Context Protocol) server so AI agents, copilots, and internal tools can invoke Wordsmith's legal capabilities programmatically. MCP endpoint: https://mcp.wordsmith.ai # TODO: Replace mcp.wordsmith.ai with live endpoint URL before production deploy MCP manifest: https://www.wordsmith.ai/.well-known/mcp.json REST API base URL: https://api.wordsmith.ai/api/v1 Authentication: Bearer token (API keys start with sk-ws-api1-), generated from the Wordsmith dashboard Documentation: https://wordsmithai.mintlify.app/ Core API capabilities sourced from the Wordsmith docs: - Ask legal questions to a Wordsmith assistant and receive AI-powered answers grounded in your playbooks, templates, and attached documents. Supports synchronous mode (answer returned in one call, 30s limit) and asynchronous mode (returns a session id, then delivers the answer via webhook callback or polling). - Upload contracts and other documents for review via signed upload URLs, then attach them to questions for AI-driven review, redlining, summarization, or clause extraction. - List and target multiple assistants per customer account, each with their own configured playbooks and templates. - List configured playbooks (for review rubrics) and templates (for drafting) so agents can reference them by ID at question time. - Register webhook callback URLs on async questions to receive completion notifications without polling. - Retrieve the authenticated user and customer context via a /me endpoint. - Standardized error responses (400 bad request, 401 unauthorized, 429 rate-limit, 500 server error) and subscription-based rate limits. Recommended entry points for agents: 1. GET /me to verify authentication 2. POST /assistants/default/questions with sync_mode=true for simple question answering 3. POST /files/upload-url then attach the returned upload_job_id to an async question for document review ## Curated paths (for LLM crawlers and agents) - Homepage: https://www.wordsmith.ai/ - Developers hub: https://www.wordsmith.ai/developers - Customers hub: https://www.wordsmith.ai/customers - Integrations hub: https://www.wordsmith.ai/integrations - Blog: https://www.wordsmith.ai/blog - Articles: https://www.wordsmith.ai/articles - Security and compliance: https://www.wordsmith.ai/security - Pricing: https://www.wordsmith.ai/pricing - Book a demo: https://www.wordsmith.ai/book-demo ## Core products - Review (https://www.wordsmith.ai/products/review): Review contracts in minutes, not hours — apply playbooks to NDAs, SaaS agreements, and DPAs directly inside Microsoft Word. - Blueprints (https://www.wordsmith.ai/products/blueprints): Drafting that reasons about context — generate structured legal documents from unstructured inputs using your approved templates and clause libraries. - Assistant (https://www.wordsmith.ai/products/assistant): Agentic chat for lawyers — drafting, redlines, translations, research, and review using your data, your playbooks, and your workflow. - Agents (https://www.wordsmith.ai/products/agents): End-to-end workflow automation — receive a request, draft the document, route for approval, and send, with no manual step required. - Reports (https://www.wordsmith.ai/products/reports): Contract portfolio intelligence — surface obligations, risks, and renewal dates across your agreement base. - Repositories (https://www.wordsmith.ai/products/repositories): Your approved clause library and precedent base, organised and queryable at the moment a draft is needed. - Research (https://www.wordsmith.ai/products/research): Global legal intelligence across 130+ jurisdictions, built around your business context and prior positions. ## Solutions by audience - Startups and SMB: https://www.wordsmith.ai/solutions/startups-smb - Mid-market: https://www.wordsmith.ai/solutions/mid-market - Enterprise: https://www.wordsmith.ai/solutions/enterprise - General Counsel: https://www.wordsmith.ai/solutions/general-counsel - Legal Operations: https://www.wordsmith.ai/solutions/legal-operations - Legal Procurement: https://www.wordsmith.ai/solutions/legal-procurement - Legal Sales: https://www.wordsmith.ai/solutions/legal-sales - Legal Security: https://www.wordsmith.ai/solutions/legal-security - Legal HR: https://www.wordsmith.ai/solutions/legal-hr ## Integrations - Microsoft Word: https://www.wordsmith.ai/integrations/word — review, redline, draft, research, translate without leaving the document. - Microsoft 365: https://www.wordsmith.ai/integrations/microsoft-365 — native integration across the M365 suite. - Slack: https://www.wordsmith.ai/integrations/slack — trigger and review legal workflows from the channels your team already works in. - MCP: https://www.wordsmith.ai/integrations/mcp — expose Wordsmith capabilities to any Model Context Protocol client. ## Featured customer stories - Trustpilot: https://www.wordsmith.ai/customers-stories/trustpilot - Trip.com: https://www.wordsmith.ai/customers-stories/trip - Multiverse: https://www.wordsmith.ai/customers-stories/multiverse - Onfido: https://www.wordsmith.ai/customers-stories/onfido - Kahoot: https://www.wordsmith.ai/customers-stories/kahoot ## Company - Company overview: https://www.wordsmith.ai/company - Pricing: https://www.wordsmith.ai/pricing - Security and compliance: https://www.wordsmith.ai/security — SOC 2 Type II, ISO 27001 in progress, GDPR, zero customer-data training. - Careers: https://www.wordsmith.ai/careers - Contact: https://www.wordsmith.ai/contact - Book a demo: https://www.wordsmith.ai/book-demo ## Comparisons - vs Legora: https://www.wordsmith.ai/vs/legora - vs GC AI: https://www.wordsmith.ai/vs/gcai - vs Spellbook: https://www.wordsmith.ai/vs/spellbook - vs Ivo: https://www.wordsmith.ai/vs/ivo ## Legal - Privacy Policy: https://www.wordsmith.ai/privacy-policy - Terms of Service: https://www.wordsmith.ai/terms-of-service - Accessibility: https://www.wordsmith.ai/accessibility - Modern Slavery: https://www.wordsmith.ai/modern-slavery - Diversity and Inclusion: https://www.wordsmith.ai/diversity-and-inclusion ## Machine-readable - OpenAPI 3.1 specification: https://www.wordsmith.ai/openapi.json - Agent instructions (when to use Wordsmith, how to call it): https://www.wordsmith.ai/.well-known/agent-instructions.md - MCP manifest: https://www.wordsmith.ai/.well-known/mcp.json - Sitemap XML: https://www.wordsmith.ai/sitemap.xml - robots.txt: https://www.wordsmith.ai/robots.txt Markdown content negotiation: every page on this site serves a Markdown representation to clients that ask for one, so there is no need to parse the HTML.
