Sandstone vs Wordsmith: Two AI Platforms for In-House Legal, Compared
Wordsmith and Sandstone both pull in-house legal work out of the inbox and into a system. Both sit in Slack, email, and Word. The differences show up underneath: how much of your existing content comes across, how permissions are enforced once it's there, and how much of contract execution each platform carries. Here's a side-by-side.
Sandstone vs Wordsmith
| Capability | Sandstone |  Wordsmith |
|---|---|---|
| Primary focus | AI-native operating system for in-house legal work, including contract execution | Operations platform and legal front door for in-house teams |
| Where the work happens | Slack, email, and existing business systems | Slack, email, Microsoft Teams, Word, and shared document repositories |
| Intake and triage | Structured intake; agents interpret intent and route with full context attached | Captures, triages, and routes every request, with owners and SLAs |
| Document sync at scale | Mapped ingestion pipelines that sync and structure millions of documents out of existing systems, so context is drawn from your full document set rather than a sample | Connected sources |
| Permissions | Permissions mapped across every connected integration, so access rules hold consistently no matter which system a request or a document came from | Per-integration access |
| 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 before anything moves | Deployed agents |
| Approvals and workflows | Multi-step approvals and conditional workflows, including drafting triggered from Salesforce | Self-serve workflows deployed to procurement, sales, and HR |
| Contract repository | Serves as system of record, with contracts connected to matters, counterparties, and obligations | Approved templates plus connected external document stores |
| CLM coverage | Replaces a CLM for teams that want intake, execution, and system of record in one platform, and runs alongside one where an existing investment makes that the better call | Positioned as an operations platform rather than a CLM |
| Internal collaboration | Legal works a request together in the app or the plugins — comments and drafts stay behind the scenes, and business or external parties are brought in only when you choose | Shared task view |
| Acting back in source systems | Replies and actions go back to Slack, procurement, and contract systems under a shared team identity, with permissions mapped across those integrations centrally | Agent responses |
| Institutional knowledge | Past decisions mapped into a knowledge base that compounds across matters | AI workers trained on the team's own rules; drafting engines they call Blueprints |
| Reporting | Cycle time, risk exposure, capacity, and deviation rates | Volume, turnaround, and cost saved, reported team by team |
| Best fit for | Teams that want requests, contract execution, and the contract record in one system, replacing a separate CLM or repository | Teams that want a front door and self-serve answers, with documents left in their existing repositories |

Frequently asked questions
In Sandstone you build the workflow step by step rather than deploying an agent and describing what you'd like it to do. You set which steps run, in what order, what may and may not happen at each one, and where a human approval is required before anything moves. For a large enterprise this is usually the gating question in a security review, so ask any vendor to show you the configuration surface in a demo rather than describe it — and ask what happens at the boundary, when a request matches nothing that was set up.
Sandstone maps permissions across every integration, so the rules hold consistently whether a document came from your CLM, your procurement tool, or a Slack channel. Worth asking any vendor how access is resolved when a single request touches three systems with three different permission models.
In Sandstone, yes — the team can comment and draft on a request inside the app or the plugins without any of it surfacing to the requester, then bring in a business stakeholder or outside counsel when it's ready. Ask any vendor specifically whether internal discussion is separable from the requester's view, because collaborative means different things in different products.
In Sandstone it can go out under a shared team identity, so the business sees the legal team rather than a bot — and the permissions behind it are mapped centrally across integrations rather than resolved per connector. That matters for how a request is received and for what the audit trail shows later.
It's technically possible, but we'd argue against it. Both products want to be the front door for the business, and two front doors confuses the people you're trying to make life easier for. This is a pick-one decision.
