Open WebUI vs OsmO

Unknown callers are screened automatically: spam is silenced while legitimate messages, bookings and urgent calls are passed through to you.

Set rules once — let family straight through, have a chosen character handle unknown numbers, silence telemarketers, and send after-hours calls to voicemail-style messages.

Feed the assistant your website, PDFs, Google Docs or Sheets, FAQs and Google Maps listing so it answers callers from your own materials rather than guessing.

Read a short line aloud and OsmO clones your voice so calls are answered as you, using either your voice or one of the studio and character voices.
