Overview

Dioptra redlines contracts using AI, and the detail that matters is what it redlines against: your own playbooks and previously executed contracts, not a generic notion of standard terms.

That distinction is the whole game in contract review. Every legal team has positions it will and will not accept, and those live in playbooks and in the history of what has actually been signed. A tool marking up against generic standards produces suggestions a lawyer has to re-evaluate from scratch; one working from your executed contracts is proposing what your organisation has already agreed to before.

Worth knowing before you evaluate: Icertis has acquired Dioptra, announced on the site itself, to build an AI-first contracting experience. The product currently operates with its own pricing, signup and demo path, but ask about the roadmap and how it will sit inside Icertis before committing to a multi-year arrangement. As always, generated redlines inform a lawyer’s judgement rather than replacing it.
