Summize is contract lifecycle management (CLM) software with AI contract review inside Microsoft Word, and it does not publish a price. Its homepage describes a “contract intelligence system” with a knowledge layer, a contract operations layer and an AI agents layer, built for Microsoft-native legal teams (summize.com). Its pricing URL is a demo-booking form, and its security page says it holds ISO 27001 but has not yet earned SOC 2 (summize.com/security).

What Summize is
The homepage calls Summize a contract intelligence system that “wraps around the tools your business already uses” (summize.com). In practice it is a CLM: requests come in through Outlook or Teams, contracts are drafted and reviewed, and a repository holds the result.
Who Summize is for
Best for: Legal teams that live in Microsoft 365 and want intake in Outlook or Teams and AI review in Word, with sales, finance, HR and procurement requesting contracts.
The site has team pages for Legal, Sales, Finance, HR and Procurement. Customer logos, quotes and review scores on it are vendor-selected and we did not verify them. It is not a law firm practice-management product.
Summize pricing
There is no public price. The /pricing URL is titled “Book a CLM Demo” and contains a demo request form with no plans or amounts (summize.com/pricing). We show no figure. Ask for a written quote that says what is included in implementation and what changes at renewal.
Notable features
The Word AI add-in is described as giving a first-pass redlined review and as generating redlines aligned to your playbooks; you can accept, modify or reject each AI suggestion. Contract intake is embedded in Microsoft Teams and Outlook.
SIA (Summize Intelligence Agents) is the AI agent layer, including an “Ask SIA” assistant. The site says the repository can be queried with Microsoft Copilot and that SIA connects to Copilot via MCP; a separate page offers a connection to Claude.
Security and data handling
The security page shows an ISO 27001 accreditation and says third-party penetration testing is done regularly (summize.com/security). On SOC 2 it is explicit: it says it audits its infrastructure in line with SOC II and ISO standards and intends to work toward SOC II accreditation in the future, so it claims no SOC 2 report today. Ask for the ISO certificate and what it covers.
On AI data, the page says customer prompts, completions, embeddings and training data are available only to that customer, are not shared with other customers or OpenAI, and are not used to improve OpenAI models. That is a vendor statement; get it in the contract.
Summize vs Juro and Luminance
These are the two names searchers pair with Summize. All three sell AI contract review, and none publishes a price. The differences below come from each vendor's own pages (summize.com, juro.com, luminance.com), read 2026-11-02; we did not test any of them.
Summize vs Juro. Both are CLMs for in-house and business teams. Summize puts its review in Word and its intake in Outlook and Teams. Juro describes a browser-based, AI-native platform with AI review, self-serve templates and a repository, and its pricing page says plans are custom, with unlimited users and prices based on contract volume and integration complexity. On security, Juro's site names SOC 2 Type II; Summize's names ISO 27001 and says SOC 2 is a future intention. See our Juro profile.
Summize vs Luminance. Luminance presents a “Contract Intelligence Platform” with Negotiate, Discover and Automate pillars, and its pages name both ISO 27001 and SOC 2 Type II. It shows no price and sends visitors to a demo request, as Summize does. Both are vendor claims. See our Luminance profile.
Before you rely on this
We did not test the product. Capability, security and customer statements are the vendor's own, and the AI features are described in marketing terms without published accuracy results. Check the demo against your own contracts.
Summize alternatives
Contract lifecycle platforms: Ironclad, Juro and LinkSquares. Enterprise review and diligence: Luminance. Other lifecycle profiles: SpotDraft.
How to choose
- Decide first whether you need a repository and workflow platform or only a review assistant in Word.
- Run your own NDA, MSA and a messy third-party paper through a trial, not a demo set.
- Ask for the ISO 27001 certificate and the written terms on data use and model training; confirm SOC 2 status if your procurement requires it.
- Get a written quote that includes implementation, and compare it with one lighter tool.
The bottom line: Summize is a CLM with AI review in Word and intake in Outlook and Teams. It publishes no price and says it has no SOC 2 report yet, so request a written quote and the ISO certificate.
