Short answer: Streamlingo is a German (Karlsruhe, KIT spin-off) church translation tool with a genuine GDPR posture and a free 1-hour/month tier, priced at €44/month for 5 hours of translation plus 250 listener-hours. LiveInterpret.AI is also EU-hosted and GDPR-first, but never meters listeners — a growing congregation's bill stays flat — and includes whitelabel from €99/month, which Streamlingo doesn't offer at any price. If a German domestic vendor matters more than listener math, Streamlingo genuinely fits; if you want your own branding or don't want Easter attendance to move your bill, we fit better.

Streamlingo has real German-market trust: a Karlsruhe Institute of Technology spin-off with a syndicated story in German church press (epd), an explicit "your data is never used for AI training" pledge, and a free 1-hour/month tier that costs a tiny congregation nothing. If a German church specifically wants a domestic vendor for the invoice and support language, that preference is legitimate and we won't argue it away.
Streamlingo's €44 plan meters two things at once: translation hours and listener-hours. A congregation that grows — or just has a big Easter Sunday — can cross the included 250 listener-hours and start paying €0.10 per listener-hour over. We never count listeners at all, on any plan: a packed Easter service costs the same as a quiet Sunday with the same run time. We also include whitelabel (your church's own name, logo and colors) from €99/month; Streamlingo doesn't publish a whitelabel tier at any price. And our packs from €19 stay valid 12 months with zero subscription commitment.
Estimate your own listener-hours for a normal Sunday and for your busiest one (Christmas, Easter) before comparing prices — that number changes Streamlingo's bill and never changes ours. Then run both on a Thursday soundcheck: ours takes about two minutes to provision, with free unlimited practice mode before you spend any of the 30 free real minutes.
It depends on your listener count. Streamlingo's €44/month plan can be cheaper for a small, stable congregation that stays under 250 listener-hours a month. Once attendance or run time grows past that — Easter, a building move, a second language — listener-hour overage at €0.10/h adds an unpredictable amount; LiveInterpret.AI's €49 Standard covers a weekly 90-minute two-language service with EU hosting and branding included at a flat price regardless of attendance. Neither of us is "cheapest" — headset-rental systems cost €200–500 per event, which is the number both of us beat.
No. Both are browser-based, no app to install. The difference we document is locked-screen behavior: LiveInterpret.AI audio keeps playing when the phone locks; Streamlingo doesn't state this either way as of 2026-07-30.
Both publish a genuine EU/GDPR posture — this is one of the few comparisons on our site where that's true of the rival too. Streamlingo is German-hosted with a "never used for AI training" pledge; we're EU-hosted with a published DPA and tracking-free audience pages. If a domestic German vendor and invoice matter to your board, that's a legitimate reason to pick Streamlingo.
Nothing. Signup to a live event page takes about a minute, practice mode is free forever, and the first 30 real minutes are on us. There's no migration — your sound desk feed and a QR poster are the whole setup.
