Every call answered. Every line yours.
Linedesk is the open-source AI receptionist you run on your own server. It answers every call, books the appointment and hands over to a person when needed. You own the code and the data.
One Docker project, about 1.5 GB of RAM. Rather not run a server? Linedesk Cloud is coming soon.
Brightwater Plumbing, this is Maya, the AI receptionist. How can I help?
Hi, our water heater stopped working this morning. No hot water at all.
Sorry about that. I can get a technician out to you. Does Thursday between 9 and 11 work?
Thursday works.
You're booked. I'll text you a confirmation in a minute.
What happens when your phone rings
Your AI receptionist answers on your own number and tells callers it's an AI. In these examples she's called Maya: you pick the name, the voice, the greeting, the hours and what counts as urgent.
Picks up on the first ring
Day, night and weekends. Nobody waits on hold.
Finds out what they need
Name, address and the problem in the caller's own words.
Books the job
Into your calendar, inside your working hours, with buffers and minimum notice.
Hands over to a person
Puts the caller through to your on-call number, or flags the call for a callback right away.
Lands in your inbox
Recording, transcript and a short summary, sorted by whether you have to act.
Only the calls that need you.
Maya sorts every call by who has to act. What she handled on her own waits in its own view.
One call at a time
Open a call, read the summary, mark it done. The next one is already there.
Recordings you can trust
Every call keeps its audio, the full transcript and what Maya did, so you can check any answer.
Calm by default
You only get a notification when a person is needed. Everything else waits quietly in the inbox.
Works on any phone line
Forward your existing number or get a new one. Your callers don't notice a change.
Run the whole line on your own server
The code is on GitHub under AGPL-3.0. Recordings, transcripts and customer data are stored on a machine you control. Calls run through the carrier and AI providers you pick, on your own accounts.

Where Linedesk fits
Answering services send calls to people. Closed AI receptionists keep the code to themselves. Voice platforms give you parts to build with. Linedesk is the finished product, with the source.
