Custos/legalos
A contract-lifecycle product built on a tabular-review foundation, organised around counterparties and bulk intake, shipping under the legalos brand.
legalos is Custos's rebrand and repositioning of the upstream Mike tabular-review tool into something closer to a contract-lifecycle product. The headline move is organising the workspace around counterparties - vendors, customers, internal parties - rather than just documents in a grid. A bulk-upload triage queue auto-classifies incoming contracts and routes them to projects, and a structured "Key Terms" panel pulls facts out of each upload and tracks how they shift across re-uploads.
Under the hood, Custos has wired in an xAI Grok provider with per-user keys and moved storage onto Supabase. The original tabular review surface hasn't been abandoned - cells are now versioned and comparable across models - but the centre of gravity has clearly moved toward CLM workflows and the contracts pipeline that feeds them.
It's a single-handle effort under the Custos account. There's no public brand story beyond the legalos name, but the direction of travel is consistent: take Mike's review primitives and build a contracts product around them. Click through to GitHub if you want to see how far it's gone.
What's in it
- Counterparties + customer index Reframes the workspace around vendors, customers, and internal parties - the backbone of the CLM repositioning.
- Bulk intake triage queue Drop a pile of contracts in; each gets auto-classified, assigned a role, and routed to a project in one click.
- Structured contract facts with version deltas A "Key Terms" panel extracts effective dates, terms, and other facts from each upload and tracks how they change across re-uploads.
- Versioned tabular review with model comparison Review cells are no longer overwrite-only - every rewrite is archived alongside the model and prompt that produced it, so answers can be compared across models.
- Org-aware extraction prompts Extraction now knows which side of an agreement is "us", fixing a class of embarrassing mislabelling on uploaded contracts.
- Grok provider and Supabase storage Adds xAI's Grok as a first-class model option with per-user keys, and moves file storage onto Supabase.
