August Launches ‘Personas’ AI Memory System

Legal AI startup August has launched Personas, ‘a memory layer purpose-built for legal work’, which remembers how lawyers ‘specify formats and style preferences, [and] recurring facts’, and then applies those details where needed.

Early users found that Personas helped retain and share institutional knowledge, ‘from a partner’s memo structure, to a client’s standing instructions, so teams moved faster with fewer repetitive prompts and handoffs’, they added.

They also found that ‘in internal testing with more than one hundred lawyers, [it] improved output accuracy by more than 25% on average, and cut follow-up questions by more than twofold’.

In short, this is tapping one of the more unusual aspects of genAI, namely the ability to create outputs and actions with distinct and persistent characteristics. In this case the ability is used for a very practical and efficiency-gaining purpose at ‘the client, matter, or lawyer level’.

The feature has been in early access with select customers ‘who report significant gains in speed and accuracy from day one’, August stated.

In terms of how they got here, the company said that for the last year August has built and tested Personas with firms to ensure it ‘captures institutional knowledge without crossing client or matter lines’.

To protect client confidentiality, ‘behind the scenes, Personas encrypts data, enforces hard client- and matter-level walls, and limits access by role with approvals – with options for data residency and enterprise key management’.

Thomas Bueler-Faudree, Co-Founder, concluded: ‘By tying memory to the boundaries professionals already live by (Client, Matter, Partner) and making scope, consent, and auditability visible in the product, Personas shows how ethically scoped memory can speed work and safeguard trust. The same pattern maps cleanly to healthcare, finance, and consulting, where institutional knowledge must be reusable without leaking across walls.’

Is this a big deal? Yes. Because, as an increasing number of innovation experts are finding, the next big movement in legal AI is to leverage knowledge within a platform more effectively and then hand it back to the end users in an improved format. Personas is a way of doing this.

The move follows the company rebranding and raising $7m in fresh funding.
