A chat assistant, or an inbox that runs itself?
Copilot helps when you ask it to. Relynt works on its own, triaging every thread and drafting replies in the background, so your inbox is handled before you think to ask.
Proactive, not on-demand
Copilot waits for a prompt. Relynt triages and drafts every thread automatically, so you review a queue that's already done.
Purpose-built for email
Relynt is built around the inbox (triage lanes, VIP detection, send scheduling), not a general assistant bolted onto your apps.
Works in Gmail and Outlook
Relynt runs in both inboxes, not just the Microsoft stack, and stays read-only until you turn on action.

An assistant you prompt, or a teammate who just handles it.
Copilot is powerful when you remember to ask and write a good prompt. Relynt needs no prompting. It reads every thread as it lands, drafts replies in your voice, and surfaces only what needs you. The work is done before you'd have thought to ask for it.
