Sandstone vs Chamelio: Contract Intelligence, or the System for All Legal Work?
Chamelio and Sandstone are both AI-native platforms built for in-house legal teams. Chamelio grew out of AI contract review and centers its platform on negotiation, a contract repository, and contract workflows. Sandstone starts from the full legal function: requests of every kind, arriving from the systems where the business already works, with counterparty history and prior decisions attached. The differences show up in how far beyond contracts each platform reaches and how deeply each connects to the enterprise systems where legal work begins. Here's a side-by-side.
Sandstone vs Chamelio
| Capability | Sandstone |  Chamelio |
|---|---|---|
| Primary focus | AI-native operating system for in-house legal work, with contracts as one part of it | Legal intelligence platform built around contract review, negotiation, and a contract repository |
| Origin | Built around legal context: counterparties, relationships, and prior decisions across every request type | Started in AI contract review and expanded into a broader platform |
| Work beyond contracts | Advisory questions, policy and compliance requests, employment and product matters, and contracts in one queue, with one record | Contract-centered: review, negotiation, approvals, and obligations |
| Intake and triage | Structured intake from Slack (backed by a direct Slack partnership), Microsoft Teams, email, ServiceNow, Jira, Asana, Zip, Coupa, Salesforce, and other business systems; agents interpret intent and route by expertise and capacity | Requests captured through structured workflows |
| Where the work happens | Slack, Microsoft Teams, Outlook, Word, and the enterprise systems where requests start: ServiceNow, Jira, Asana, Zip, Coupa, Salesforce, HubSpot, SAP, and more | Microsoft Word, shared drives, email, communication channels, and CRM, per public materials |
| Contract review | Surgical redlines in Word from your playbooks, with comment replies, accept-and-reject, and multi-source citations | Word-native redlining guided by playbooks |
| How automation is defined | You build workflows step by step: which steps run, in what order, what may and may not happen at each one, and exactly where a human approval is required | Configurable AI agents for routine contract work |
| Permissions across systems | Permissions mapped across every connected integration, so access rules hold no matter which system a request or document came from | Access controls within the platform |
| Repository | One repository of contracts, companies, people, and decisions, synced from SharePoint, OneDrive, Box, or Drive, with AI-extracted custom fields | Contract repository with AI-extracted metadata |
| Acting back in source systems | Replies and actions go back to Slack, Microsoft Teams, ServiceNow, Jira, Asana, Zip, Coupa, Salesforce, and contract systems under a shared team identity | Responses within supported channels |
| Reporting | Cycle time, risk exposure, capacity, and deviation rates across all legal work, not only contracts | Insights on legal workload and impact |
| Best fit for | Enterprise legal teams that want intake, context, contract execution, and the record for all legal work in one system | Teams whose main need is faster contract review and a smarter contract repository |

Frequently asked questions
If contract review is genuinely the whole problem, a contract-focused tool can solve it, and we'll tell you so. Most in-house teams find that contracts are only part of the queue: advisory questions, policy requests, and employment and product matters arrive through the same channels and need the same context. Sandstone earns its place when you want all of that in one system rather than contracts in one tool and everything else in an inbox.
A product counsel question in Slack, a ServiceNow ticket asking whether a vendor needs a DPA, a Jira issue about open-source licensing, and an NDA from Salesforce all land in the same queue, get triaged by the same rules, and draw on the same record of prior decisions. The answer to the third request of a kind starts from the first two.
Ask every vendor to show, not describe, three things: a request arriving from the system your business actually uses, a reply going back into that system, and how permissions are resolved when one request touches several systems. Sandstone integrates with ServiceNow, Jira, Asana, Zip, Coupa, and Salesforce as well as Slack, Teams, email, and Word, with permissions mapped across all of them.
It's technically possible, but we'd argue against it. Both products want to hold your legal knowledge and your workflows, and splitting them means context lives in two places. This is usually a pick-one decision.
