Hermex is a native iPhone and iPad client for your self-hosted Hermes agent. Connect to a reachable Hermes Web UI server, or enable the optional Bot Mode beta to connect directly to a Hermes agent host. Open existing sessions, start conversations, and follow streamed responses, tools, and reasoning as they arrive. Queue, steer, or stop an active run. Review file edits as diffs, browse workspace files, send photos and files, and dictate messages. Manage Kanban boards and cards, browse Tasks, Skills, Memory, and Usage, and choose models, profiles, and reasoning settings. Bot Mode adds a Bots inbox, Desktop sections, reactions, quick replies, approvals, questions, and group rooms. Live Activities keep working runs visible on the Lock Screen and Dynamic Island. Optional notifications let you know when work finishes or needs your attention. The share extension stages content from other apps for you to review and send. Agent execution happens on your configured server, not on the iPhone. Your server owns your conversations, tools, and workspace. Recent sessions and messages may be cached locally for read-only offline viewing; clear that cache from Settings. There is no Hermex-hosted agent backend, tracking, or analytics service. Optional push notifications use an open-source, self-hostable relay. Message previews are encrypted on your Hermes host and decrypted on your iPhone; the relay handles device tokens, notification metadata, and ciphertext, never message text, server URLs, or Hermes server credentials. Push is off until enabled. Hermex has no in-app account creation or in-app purchases. You need your own reachable Hermes server. Not affiliated with Nous Research.
