Both Miramis and Summize are AI-native contract management platforms with strong UK/European credentials. The differences sit in architectural philosophy, repository depth, native compliance, and lifecycle coverage.

Miramis approach
Repository depth and search
Summize
Miramis
Native European compliance
Summize
UK-based with strong Microsoft ecosystem integration, but not specifically architected for European regulatory environments. No native Nordic eID support (BankID, MitID), no native eSigning - integration with DocuSign or other eSign tools is required for execution. Standard eIDAS support via third-party integration rather than as a core platform capability.
Miramis
Embedded-first vs. platform-first
Summize
Miramis
The System of Record for Your Contracts
Summize's core innovation is embedding contract workflows into the tools where work happens - Word, Outlook, Teams, Slack. It's a smart approach for organisations heavily invested in Microsoft 365 where adoption is the primary CLM challenge.
Miramis takes a different approach: a focused CLM platform that serves as the strategic system of record for contracts, with embedded layers where they add value. Browser-based workflows for centralised contract operations. Microsoft Word add-in for legal teams who prefer to work in Word. Native integrations with Salesforce, HubSpot, and Microsoft Outlook for sales and business teams. The platform consolidates contract data, workflows, AI capabilities, and intelligence in one place - while still meeting users in their preferred tools where it makes sense.
For organisations that want contracts as a strategic asset rather than a process distributed across embedded tools, the focused-platform approach delivers depth that decentralised models cannot.
Built in Stockholm for European Mid-Market and Enterprise
Summize is UK-based with strong Microsoft ecosystem credentials. Miramis is Stockholm-based and architected specifically for European regulatory environments. The difference shows up in compliance specifics.
Native eIDAS-compliant eSigning is included in Miramis - no separate DocuSign subscription required. BankID is natively supported for Swedish counterparties. MitID for Danish. eIDAS for international parties. Multiple signing methods can be used on the same contract for cross-border agreements. GDPR-native data residency is the default. ISO 27001 certified, SOC 2 compliant, regular penetration testing, and contractually-guaranteed exclusion of customer data from AI model training.
For organisations operating in the Nordics and across Western Europe where compliance is not optional, Miramis is built for that environment from the architecture up. Summize meets eIDAS through integrations and supports European customers, but the compliance posture is general rather than European-first.
Every Contract Queryable in Plain Language
Both Miramis and Summize use AI to extract metadata and surface contract insights. The difference is where that intelligence lives in the product architecture.
In Summize, AI-powered review and analysis happen primarily in the embedded layer - inside Word, inside Outlook, inside Slack via Ask SIA. The standalone repository is functional but secondary, and reviewers consistently mention search and customisation limitations. For organisations whose primary need is reviewing individual contracts, this is an effective design.
For organisations that need contracts as a queryable knowledge asset across the full portfolio, Miramis approaches it differently. PLAI turns the entire repository into interactive intelligence - "Which contracts auto-renew before December?" "What's our total exposure to MFN clauses?" "Which agreements have non-standard limitation of liability?" Get the answer in seconds. Save custom filtered views, export to CSV for reporting, run portfolio analysis across thousands of agreements. Bulk-upload legacy contracts and PLAI extracts metadata, structures the archive, and makes it queryable in minutes.
This is the difference between AI for individual contract work and AI as the engine of a strategic contract intelligence system.
One Platform, One Subscription, eIDAS Built In
Summize requires a separate eSigning tool - typically DocuSign - for contract execution. The integration is clean, but it's a separate subscription, separate cost, and separate vendor relationship.
Miramis includes eIDAS-compliant eSigning natively integrated into the contract workflow at no additional per-user cost. For Nordic businesses, BankID and MitID are built in. For international counterparties, standard eIDAS signing is included. For teams that prefer DocuSign or other signing tools, integrations are available - but most organisations find the native signing covers their use cases without needing a separate per-user signing subscription.
For mid-market and enterprise organisations evaluating total cost of ownership, removing the separate eSign subscription often makes the Miramis total cost lower than Summize plus DocuSign combined - while consolidating the workflow into one platform.
