The difference
Prompts for AI apps, or writing in every app
Lemon leads with voice-to-prompt for AI apps such as ChatGPT, Claude and Cursor. It also offers plain dictation. If most of your day is prompting AI tools by voice, it is aimed straight at that.
Scrubbr writes the prompt too, and the rest of your writing. Hold Option in Gmail and it drafts the reply. Hold it in Slack and it writes the message. Hold it in ChatGPT and it writes a prompt with the details already in it. The context comes from your email, chat, calendar and meeting notes, so you do not paste it in.
Lemon's policy names Google services and lists no others by name. Scrubbr also reads Outlook, Slack, Microsoft Teams, Google Chat, Outlook Calendar and Granola. See Scrubbr for AI prompts.
