Everything your worship service puts on screen, in one calm place.
JTM Cast helps your church prepare and present Scripture, hymn lyrics, and media โ with a preview-first workflow, so nothing reaches the congregation until you decide it should.
Runs in your browser. No installation required for the cloud edition.
Built around how a service actually runs
Prepare beforehand, operate calmly during worship. Every change is previewed first and goes live only when you press TAKE.
Worship program management
Build your order of service in advance โ Scripture readings, hymns, and media in sequence โ then step through it during worship.
Scripture display, multiple translations
Search for a passage and project it instantly. Show more than one translation side by side โ including English and Japanese versions together.
Hymn lyrics
Find hymns by title, number, or a line of the lyrics, and present them verse by verse with clean, readable styling.
Image & media projection
Upload announcement slides, artwork, and video, organize them with tags, adjust size and position, and bring them on screen when needed.
Prompter & stage outputs
Separate output windows for different audiences: a prompter view for the person speaking, and a stage & broadcast view for screens and cameras.
Multiple devices, in sync
Operate from one computer and project from another. Your program, hymns, and settings stay synchronized across devices in real time.
Import your own translations
The translation your church actually reads from can be brought in as a CSV file — one row per verse, with the column names listed further down this page — and it appears alongside the translations already included. Book names can be written in any language — include the book-ID column and every row is filed by that ID, and your own book names are what appear on screen. Translations you import stay private to your church — no other church can see them. Please import only translations your church holds the rights to use. Download a sample CSV →
Move over from PowerPoint or ProPresenter
You do not have to rebuild years of material. Hymns and their lyrics come across from ProPresenter, and a PowerPoint deck comes in as slides — its text, its pictures, and where they sit on the slide. Starting with JTM Cast does not mean starting from nothing.
Smooth on the day
Lyrics and Scripture change the moment you press TAKE, with no stutter on the screen the congregation sees. Worship does not wait for software.
AI voice assist
Optional speech recognition listens for spoken Scripture references โ in English or Japanese โ and suggests the passage, ready for you to review and project.
What it looks like in the room
The operator works on one screen. The congregation and the speaker each get their own.
Screens are shown with sample data. The worship scene behind them is an illustration.
How it works
From sign-in to Sunday morning in four steps.
Create your church account
Sign up at cast.mannasys.com. Each church gets its own private workspace โ your data is never visible to other churches.
Prepare the service
Build the program: add Scripture readings, pick hymns, and upload the slides and media you plan to show.
Open the output windows
On the projection computer, open the stage & broadcast window and, if you use one, the prompter window for the speaker.
Preview, then TAKE
During worship, line up the next item in preview and press TAKE when you are ready. Only TAKE changes what the congregation sees.
Bring your own Bible translation
The translation your church actually reads from, on screen next to the ones already included. Import is available on every plan, including Free — and the sample file below is yours to download right now, with no account needed.
Start from the sample
A ready-made CSV with the correct header row and twelve verses. Open it in any spreadsheet, replace the rows with your translation, save as CSV, and import.
โฌ Download the sample CSV (English) โฌ Sample with Japanese headers โฌ Sample with Shona headers
The English and Japanese samples carry public-domain verses (the King James Version and the 1955 Japanese Colloquial Bible). The Shona sample carries the header row and three rows to overwrite. Please import only translations your church holds the rights to use.
Fill in the file
Keep the header row from the sample — the importer looks for those column names. One row per verse. Save as CSV (UTF-8).
Open the import screen
Sign in with a church administrator account, open โ๏ธ System settings, choose the ๐ Bibles & translations tab, then ๐ฅ Bulk Bible import.
Upload
Under ๐ค Upload local Bible files, choose your CSV (several at once is fine) and press Import. The version code is taken from the file name; you can change it and the display name on the row before importing.
Use it
The translation appears in the version list beside the built-in ones, shown with the book names you wrote. It stays private to your church.
What each column means
| Column | Meaning | Example |
|---|
See it in action
Pick a passage from the order of service, check it in preview, then press TAKE to go live. On the left, the operatorโs screen; on the right, what the congregation sees at the same moment.
In use where it matters
JTM Cast is not a prototype. It runs real worship — from weekly services to gatherings of hundreds.
Pricing
One price for your whole church. Cancel any time. The free plan has no time limit.

Frequently asked questions
Do we need to install anything?
No. The cloud edition runs entirely in a modern web browser at cast.mannasys.com. There is also a local install edition for churches that want to run JTM Cast on their own computer โ it offers the same features plus live streaming.
Can we stream our service to YouTube?
Yes, with the local install edition. It adds video switching and streaming to YouTube Live on top of everything the cloud edition does. The cloud edition focuses on projection and presentation.
Is our church's data private?
Yes. JTM Cast is multi-tenant by design: each church's programs, media, and settings are isolated and never visible to other churches.
Can several people operate it at the same time?
Yes. You can sign in from multiple devices, and changes to programs, hymns, and settings synchronize between them. During live operation, the preview-and-TAKE workflow keeps output changes deliberate.
What can accidentally end up on screen?
Very little. Preview operations never reach the live output โ only pressing TAKE updates what the congregation sees. There is also a one-touch way to clear the projection, and an undo for accidental clears.
Can we use our own Bible translation?
Yes. A church administrator can import a translation as a CSV file, one row per verse, and several files can be imported in one go. The column names are listed in the translations section, and the header row may be written in any language JTM Cast supports. Book names can be written in any language, as long as the file also carries the book-ID column (GEN, PSA, MAT, REV …) that tells JTM Cast which book each row belongs to; without that column, book names are matched against the built-in English and Japanese names instead. Exporting the translations you already have gives you a CSV that already has the column, so it doubles as a template. The imported translation then appears in the version list beside the ones already included, shown with its own book names, and stays private to your church. Please import only translations your church holds the rights to use.
Which languages does it support?
The app is offered in English and in Japanese — the sign-in screen, the operating console, and the manual all have an English version. A Shona translation is under way; the parts not translated yet appear in English. Scripture can be displayed in multiple translations, including English versions, and the AI voice assist understands both English and Japanese.
