What is Spectra?

Spectra is a complete worship presentation appfor churches. Browse and display scripture, manage worship song libraries, build custom slides, schedule your service — and optionally let AI detect Bible verses from your pastor's sermon in real-time.

Key highlights:

• Full presentation suite — Scripture, songs, text slides, media, imported documents (PDF, Word, Markdown), and custom branding
• Song-level theming — One pick sets the backdrop image, overlay tint, motion layer, logo position, and decorative font for every verse, chorus, and bridge in a song
• Cinematic title slides — 5 layout styles (including the chunky “Concert” style with glow halo) and 10 decorative display fonts — Lilita, Lobster, Pacifico, Cinzel, Anton, and more
• Video backdrops — Drop a 50 MB loop (mp4 / webm / mov) under any slide; served from a local HTTP bridge for reliable seeking
• Theme Studio designer — Drag-and-drop WYSIWYG canvas for placing logo, verse text, and reference exactly where you want them — coexists with the form-based branding settings
• Animated lyric reveal — Line-by-line or word-by-word song lyrics with 33 entrance animations including typewriter, plus per-line emphasis loops
• Justify alignment for lyrics — Canvas-packed lines fill the slide width naturally without scattering words like CSS-justify does
• Pre-recorded timing — Capture cadence in a video-editor-style timeline (waveform, draggable markers, scrubbable playhead); live verses auto-advance hands-free
• Split-layout slides — Two side-by-side text columns with progressive reveal + spotlight controls — perfect for prayer / call-and-response moments
• Animated backgrounds — 12 ambient styles (Aurora, Bokeh, Stars, Worship rays, Snow, Rain, Fireflies, Embers…) so the screen is never static
• Always full-screen text — Auto-fit picks the largest font that fills the projector at any resolution
• AI verse detection — Optionally detect Bible references from live speech, hands-free with Autopilot + voice commands
• NDI broadcasting (up to 4 outputs) — Ship a projector mirror and transparent lower-third overlays to OBS, vMix, ATEM, and other NDI receivers from the same machine
• Works offline — Everything runs locally on your machine
• Cross-platform — Available for macOS and Windows
