Security
Read-only
None of the 21 tools writes, edits or deletes: the server only reads the Argos database, and your assistant cannot change anything in your account.
Revocable key
Each key has a name, is shown only once and is revoked in one click: the server then answers in preview only, immediately. An address that carries a key is kept like a password.
Free accountNothing else goes through
Argos only receives the parameters of the tools called (a name, a country, a code), never your chats or your files.
