Ivo
Ivo is AI contract review for in-house legal teams. It applies redlines directly in Microsoft Word or Google Docs, evaluates agreements against your playbooks and historical contracts, benchmarks clauses by governing law and industry, and queries executed contracts in plain language.
- Works inside Word and Google Docs, where contract negotiation actually happens
- Applying redlines in the document removes the translation step a review report creates
- Reviewing against your playbook rather than a generic standard produces judgement rather than noise
- Deriving a playbook from executed contracts turns tacit institutional knowledge into something checkable
- No pricing published anywhere, so cost requires a sales process
- No accuracy or evaluation data for redlining, leaving your own testing as the only measure
- The population behind clause benchmarks is not disclosed, which changes what a benchmark means
Luminance
Luminance is a contract platform from Luminance Technologies Ltd. spanning Draft, Negotiate, Analyze, Comply, Investigate and Collaborate. It describes a mixture-of-experts architecture using probabilistic consensus across multiple models, with over 1,000 customers named on the site.
- A customer list including major enterprises and magic-circle law firms
- Coverage from drafting through post-signature investigation in one platform
- Multi-model architecture is a defensible answer to single-model brittleness
- Surfacing model disagreement aligns with the asymmetric cost of contract errors
- Performance percentages are unaudited and state no baseline
- The models behind the architecture are not disclosed
- A six-module platform is an implementation project, not a subscription
