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 account

Nothing else goes through

Argos only receives the parameters of the tools called (a name, a country, a code), never your chats or your files.
