The short answer
Use ChatGPT when you want to think, write or research in a conversation. Use Arkemis when you want something done where you already work: a reply sent, a meeting moved, a note filed, without switching windows or copying and pasting.
Where they differ
- Where you use it: ChatGPT runs in its own app or browser tab. Arkemis sits at the edge of your screen and works over whatever app you're in.
- Input: ChatGPT is mostly typed, with a voice mode. Arkemis is built around holding a key and speaking.
- Doing the work: Arkemis drafts real actions in Gmail, Google Calendar, Outlook, Notion, Slack and Linear, and you approve each one before it runs.
- Dictation: Arkemis types what you say into any text field on your computer.
Using them together
They don't compete for the same moment. Plenty of people brainstorm in ChatGPT and then use Arkemis to act on the result in their inbox and calendar. Arkemis is independent and not affiliated with OpenAI.
