Audience
Busy professionals, small business owners, and people who miss important calls or receive spam and unknown calls and want them screened and handled on their existing phone number.
About OsmO
OsmO is an AI phone assistant for iPhone and Android. It answers calls you cannot take, screens spam and unknown callers, captures the caller's name and reason, and texts you a transcript and summary. It also makes outbound calls for everyday tasks like booking appointments, checking availability, chasing refunds, and waiting on hold. OsmO works on top of your existing phone number through conditional call forwarding, so there is no new number or SIM. It is free to download, with an optional Pro plan.

WarmLane
WarmLane is a 24/7 AI voice agent built for businesses that lose money every time the phone goes unanswered.
Every missed call is a customer who called the next business instead. WarmLane answers on the first ring — at 2 AM, on a Sunday, or while the owner is under a sink — and handles the call the way a well-trained receptionist would. It answers questions about services, hours, pricing and service area using your own business information, qualifies the caller, captures their name, number and reason for calling, and books the appointment directly onto your Google Calendar or Calendly. The caller gets a confirmation by text and email, which also cuts no-shows.
When a call genuinely needs a person, WarmLane forwards or warm-transfers it to you or your team, so nobody is ever left stranded. Missed and dropped calls get an automatic callback and text. Every conversation is transcribed, searchable, and exportable.

SwiftGuard
SwiftGuard is an AI receptionist for plumbing and heating businesses. When the plumber is under a sink or out on a callout, SwiftGuard answers the phone in the company's name, tells the caller it is an AI assistant, takes the caller's name, address and problem, and books the job into the connected Google Calendar based on real availability. A business chooses whether SwiftGuard answers every call or only the calls nobody picks up; forwarding is a short code dialled on the existing phone, so the business keeps its number. Callers can also move or cancel an existing appointment or leave a message, and every call lands in the dashboard with a recording, a transcript and the caller's details. Calls it cannot handle are flagged for a callback. The agent speaks English, Dutch, German, French, Italian and Spanish and switches language mid-call. Calls and transcripts are encrypted and deleted after 90 days. Three flat monthly plans include a bundle of call minutes with no per-minute charge.
