What they share
Both are desktop voice assistants for Mac and Windows. Both let you dictate into apps by voice and ask an assistant to take actions in connected apps such as Google Calendar, Slack and Notion.
What Arkemis focuses on
- Approval on every change: Arkemis shows each action in a connected app as a draft, and nothing sends, moves or deletes until you approve it.
- One sentence, several apps: a request like "reply to Maya and move our 2pm to Thursday" becomes both drafts at once.
- Integrations: Gmail, Google Calendar, Outlook, Notion, Slack, Linear, Google Drive, Docs, Sheets, Meet, Tasks and Microsoft Teams.
Pricing
Arkemis has a free plan (2 minutes of dictation and 5 assistant actions a month) and Pro at $29 USD a month. VoiceOS publishes its own plans, which third-party listings show starting lower than Arkemis Pro, so check its site for current prices.
