Our verdict

Apollo AI works inline: type a short command like /ap followed by a prompt in any textbox and it inserts a generated suggestion on the spot. Custom commands and templates let you tailor the tone and structure of what it produces. There is no dedicated interface beyond that slash command, so it stays a lightweight add-on rather than a full writing tool.
