Your volunteers deserve
to show up ready.
Volunteer training, role documentation, scheduling, and an AI assistant that answers questions from your own documents — so Sunday runs even when you’re not in the room.
Closed beta · Invite only · Built for local churches
Institutional knowledge walks out the door every time a long-tenured volunteer leaves or a staff member transitions.
Volunteers show up guessing. Role expectations, setup procedures, service flow — scattered across texts, emails, and someone’s memory.
Ministry leaders can’t be everywhere. Training, follow-up, answering the same questions weekly — it takes time no one has.
Good projects stall out. Without a system to manage follow-through, ministry momentum dies in somebody’s inbox.
Every tool your team needs.
Nothing they don’t.
Each feature answers one question: does this save a real ministry leader real time?
Role documentation
Every serve role, fully written out. Responsibilities, setup procedures, service-flow notes — structured and searchable. When people leave, the knowledge stays.
DocumentationScheduling & notifications
Volunteers know when they’re serving and what role they’re in before they walk through the door. Automated reminders, confirmed schedules, no Sunday morning surprises.
SchedulingTraining modules
Build training paths for any ministry role. MinistryOS can generate module content from documents you already have. Track who’s completed what before they step into a role.
TrainingKnowledge base
Training guides, tech manuals, SOPs, and process documents — organized by department and role. No more group texts, scattered PDFs, or tribal knowledge that walks out the door.
DocumentationMinistry teams
Organize volunteers by department. Assign training and documents relevant to each role. Everyone sees what they need — and only what they need — whether you have five volunteers or fifty.
TeamsProject management
Track ministry initiatives from idea to completion. Assign tasks, set deadlines, follow through. Events, team development, facility work — nothing falls through because no one owns it.
New
Your church’s AI. Trained on what you’ve already built.
“I Tertius, who wrote down this letter, greet you in the Lord.”Romans 16:22
Tertius was Paul’s scribe. He didn’t add to the message or interpret it. He faithfully recorded what was given to him and made sure it reached the people who needed it.
That’s exactly what this does. Upload your training guides, tech manuals, and process documents — Tertius learns your church’s way of doing things. When a volunteer asks how to start the sound system or where to find the livestream checklist, Tertius pulls the answer from what you’ve uploaded.
No generic advice. No internet searches. Just your church’s own knowledge, available to your team whenever they need it.
Got a process that only lives in your head?
Walk through it out loud. MinistryOS turns what you say into a clean, usable training document — ready to assign to your team.
No writing required. No formatting. Just talk through how you do it, and let the system do the rest.
Set it up once.
Let it run every week.
Built for leaders who don’t have time to manage another platform.
We set it up
Request access and we provision your workspace. Nothing to install, nothing to configure. Works in any browser. Ready before the end of a conversation.
Upload your documents
Add your training guides, tech manuals, runsheets, and process documents — whatever your church already has. MinistryOS indexes everything automatically so Tertius can use it.
Invite your volunteers
Send your team a link. They log in, complete their assigned training modules, and get access to Tertius whenever they have a question. They arrive ready.
Track what matters
See who’s completed training, what’s on the schedule, and where ministry projects stand — all from one dashboard. No chasing. No guessing.
Your church’s documents belong
to your church. Full stop.
MinistryOS uses Zero Data Retention on all AI processing. When Tertius answers a question, the content of that conversation is not stored, logged, or used to train any outside model. It’s processed and gone.
Your knowledge base, your training materials, and your volunteers’ activity stay within your MinistryOS workspace. We don’t sell it. We don’t share it. We don’t use it.
Church data is sensitive. We treat it that way.
Ready to stop holding
it all in your head?
MinistryOS is in closed beta. We’re working with a small number of churches right now — learning what works, fixing what doesn’t, building toward a full launch. If this is your problem, we’d like to talk.
