Browser tab, or a native app you can trust offline?

Speakflow deserves its reputation among browser teleprompters: it works on any OS, its Flow voice-scroll is a headline feature, and its real-time collaboration and API are strengths few competitors match. The reasons users consider alternatives follow directly from its web-first design, and echo through its (admittedly small) base of public reviews:

• No offline mode. Web-only means a dropped connection mid-take is a stopped prompter. For anyone recording in studios, on location, or on unreliable Wi-Fi, that's a structural risk, not an edge case.
• Scripts live in the cloud. Convenient for collaboration, less comfortable for confidential material — investor updates, legal statements, unreleased product scripts. The free tier also limits script history to 7 days.
• The Overlay isn't claimed to be share-proof. Speakflow's Overlay floats above Zoom or Meet, but the company doesn't state it's excluded from what you share — the one guarantee a meeting prompter is really for.
• Voice-scroll consistency. One independent review reports Flow tracking inconsistently at times; unlimited Flow is also reserved for paid plans.
• Price for solo users. Plus runs $15/month billed annually — $180 up front — and Studio $99/month annually. Reasonable for teams using collaboration; steep for one person who just needs to read a script.

A browser teleprompter is a page; a native prompter is part of your machine. That distinction produces every practical difference here. Because Lumi runs natively, it can work fully offline, keep your scripts local instead of on someone's server, record your take in the same app, and — the one a browser tab fundamentally cannot match — render Meeting Mode so the script exists only on your display and never in the Zoom, Meet, or Teams feed or its recordings. An overlay you position over a call window and an overlay that's invisible to the share look identical to you; to your audience, only one of them is actually private.

There's also a simplicity dividend: one app, one price, no plan matrix. Open Lumi, paste your script, and FlowPrompt keeps up with your voice — no tab management, no checking whether this month's plan includes unlimited voice-scroll.

Teams that write together. If your workflow involves a producer editing the script while the presenter reads it — live, from different machines — Speakflow's real-time collaboration is the point, and Lumi doesn't attempt it. Its API also makes sense for studios wiring the prompter into a larger production stack. Choose Lumi when you're the one on camera: recording at your desk, presenting on calls, working offline, keeping scripts private, and preferring $9/mo (or $27 once) over an annual commitment.
