- A product we built and run · AI receptionist for inbound calls
GreetKeeper is an AI phone receptionist that Hashlogics built and runs as a live product at greetkeeper.com. It answers every inbound call, books into Google or Microsoft calendars, and transfers to your team when a caller needs a person. If your business depends on the phone, you lose work when calls arrive after hours or while staff are with a customer. Voicemail only records that someone called.
The problem we set out to solve.
Calls arrive after hours, during busy seasons, and while your staff are already helping someone else.
Voicemail records that someone called, but it can't book the appointment or route the caller.
Urgent calls don't get handled the same way every time.
Booking by phone means a person on your team works the calendar by hand.
A missed-call alert tells you almost nothing about what the caller wanted.
What success needed to look like
- Answer an inbound call at any hour and understand what the caller needs.
- Book into your Google or Microsoft calendar.
- Hand the caller to a person when one is needed.
- Leave a written record of every conversation.
- Work with your existing number instead of replacing it.
How we delivered it.
- 01
Start from the unanswered call
Designed GreetKeeper around the calls that go unanswered: after hours, while staff are with a customer, and in busy seasons.
- 02
End every call in an action
Gave each call one of five endings, so it books, answers, transfers, takes a message, or escalates to a person.
- 03
Keep your number
Built GreetKeeper to sit behind call forwarding, so you keep your existing number and the phone system you already use.
- 04
Make the handoff a rule
When a caller asks for a person, or the AI is unsure, the call goes to your team.
- 05
Run it ourselves
Hashlogics operates GreetKeeper as a live product, so the team that built it also keeps it running.
What we built.
GreetKeeper sits between the caller and your business. You forward your existing number to it, and it answers every inbound call, at any hour. It answers the questions you train it on and reads the name, number and time back before it books into your Google or Microsoft calendar. When a caller asks for a person, it transfers to your team.
Every call arrives as a transcript and a short summary, so you know what was asked and what happened next. Teams with several locations get one account with per-number settings: each number can have its own hours, greeting and calendar. A webhook, signed with HMAC-SHA256 so your systems can verify it, reports each completed call, booking, message and transfer.
- ForwardYour existing number forwards the call.
- AnswerGreetKeeper picks up and hears the request.
- ActIt books, answers, transfers, or takes a message.
- RecordA transcript and short summary are written.
- NotifyA signed webhook goes to the URL you set.
When a caller needs a person, the call goes to your team instead of staying with the AI.

GreetKeeper's AI voice is one part of the product. The value is in what a call connects to: your calendar, a transfer to the right person, and a record you can act on. One rule underneath it all: the AI handles what it knows and hands off what it doesn't.
