LegalOn AI Sales Assistant Sela

LegalOn AI Sales Assistant is an Outlook add-in that suggests AI-generated reply drafts to sales reps when they open customer emails, and allows them to switch automatic responses on or off. It is currently operated as a proof of concept (PoC). After receiving an application from a participating company, LegalOn Technologies issues user accounts, and only users with these pre-issued accounts can use the add-in as a limited-access trial. We do not plan to make the add-in publicly available, and only users explicitly approved by our company can access its features.

When a user opens a target email in Outlook (an email that includes the tenant-specific receiving address in CC and has been imported into our internal system), the add-in reads the message ID, body text, and thread history via the Outlook add-in APIs and sends them to our backend API. The backend matches the message ID against our internal database to identify the corresponding email, and an AI model then generates a reply draft. The generated content is inserted into an Outlook reply or compose draft, where the user can review and edit it before sending. If the email is not registered in our system, the add-in clearly informs the user (for example, via a banner or notification) that a reply suggestion cannot be generated.

In the settings view of the add-in, users can toggle an “AI auto reply” setting on or off. When this setting is turned on and a target email is received, the server-side AI automatically generates a reply email and sends it without manual intervention.

Authentication is performed via OAuth2 using Auth0. All external communication is conducted over HTTPS only. Locally stored information is limited to configuration flags in user-specific settings; we do not send data to other external services or retain it for long-term storage beyond what is necessary for providing this service. The user interface is primarily available in Japanese.
