a teleprompter is text that scrolls, flipped left to right. that's the whole product. so it's worth asking why the category charges rent for it, and what an MIT licence actually changes for the person reading.
open prompter is free and MIT-licensed. keeping it on the App Store costs $99 a year in Apple Developer Program fees and returns nothing. that's the honest starting position, and the rest of this is the argument for why that's still the right trade.
what a teleprompter actually is#
strip the marketing off and you get three jobs.
- show the words. big enough to read at arm's length, or at three metres if you're on a rig.
- move them at your pace. a timer, a thumb, or your own voice.
- flip them. so the words survive a bounce off a piece of glass and land the right way round in your eye.
that's it. no model to train, no server to run, no content to license. a teleprompter is a text view with a scroll offset and a transform matrix. the hardest part is making the scroll feel good, and that's craft, not infrastructure.
compare that to the things software normally charges monthly for. hosting. storage. a synced database. a model doing inference. a teleprompter needs none of it. the text is already on your device. the reading happens on your device. nothing has to leave the room.
so a subscription in this category isn't paying for a running cost. there mostly isn't one.
the feature that makes it a teleprompter is the one behind the paywall#
here's the part that gets me.
mirror mode is what separates a teleprompter from a notes app. if you can't flip the text, you can't use a beam-splitter rig, and if you can't use a rig you're reading beside the lens instead of down it. everyone can see you doing it. mirror mode is the load-bearing feature.
it is also, in this category, the classic paywall.
think about why. the paywall gets placed where the pain is highest and the substitute is worst. you can live without a font picker. you can live without a countdown. you cannot live without the flip, because the glass will not un-reverse itself out of sympathy. so that's where the gate goes.
it's a defensible business decision. it's just not a technical one. flipping a view horizontally is one line in every UI framework shipped in the last twenty years. the fee isn't for the work. it's for the fact that you can't say no.
what open source actually changes#
"open source" gets used as a vibe word, so here is the specific list of what it buys you.
- you can read the claims. the privacy posture isn't a promise on an about page. it's a repo. no analytics call, no tracking SDK, no quiet upload, and you can confirm that yourself instead of believing me.
- the feature set can't be taken back. the version you have today is licensed to you today. a future maintainer, me included, cannot retroactively put mirror mode behind a gate in the code you already hold.
- you can fork it. if the project stalls, dies, or goes somewhere you don't like, the source is sitting on GitHub and somebody else can carry it.
- your files stay ordinary. there's no proprietary container to be locked into, because the app reads the markdown you already wrote and never copies it anywhere.
that last one is quieter than the others and it might be the most important. most of the lock-in in this category isn't the licence. it's the paste box. once your script lives in someone's database in their format, leaving costs you every script you ever wrote.
what open source does not change#
being honest about the limits is the price of making the argument.
MIT is permissive. that means somebody can take this code, close it, add a subscription, and ship it. that's allowed and i knew it when i picked the licence. GPL projects like Imaginary Teleprompter chose the other way, and require derivatives to stay open. both are defensible. i picked the one that puts fewer conditions on the person downloading it.
open source also doesn't promise you a maintainer. it promises you the code. a repo can go quiet. an app can fall behind an iOS release. free software has no support desk and no refund, because there was nothing to refund.
and it doesn't make the software good. plenty of open-source tools are unpleasant to use. the licence is a property of the distribution, not of the craft. you still have to do the work.
while you're here: the other open ones#
if you searched "open teleprompter" you might have been looking for something else, and it's worth naming them.
Open Teleprompter by Eyevinn is a web-based teleprompter under Apache 2.0 that splits the controller from the display, so an operator drives the scroll on one screen while the talent reads another. that's the traditional studio shape, in a browser. it's a small, young repo.
Imaginary Teleprompter is the long-running one. GPL-3, web technologies, with desktop builds for macOS, Windows, Linux, and FreeBSD. it has been around for years and has the feature depth to show for it. development has slowed, which happens.
open prompter is the iOS one, MIT, and it takes a different position from both: the script is a file in a folder you already own, not text you paste into a box.
different licences, different platforms, same instinct. none of us think a scroll offset is worth a monthly fee.
what it costs the developer#
the fair question is what giving it away costs, so here it is.
the direct cost is small and constant. $99 a year to Apple, a domain, and time. no servers, because the app makes no network calls of its own, so there's nothing to pay for and nothing to keep up at 3am.
the real cost is that there's no revenue to buy time back with. paid apps convert support requests into a reason to keep working. a free one converts them into evenings. that's the trade, and it's why free projects go quiet. not because the developer stopped caring. because the maths ran out.
i mention it because the honest version of this argument includes the failure mode. if you want free tools to keep existing, the thing that keeps them existing is people using them, telling other people, filing decent bug reports, and occasionally buying the developer a coffee. none of that is required. the app doesn't ask, doesn't nag, and doesn't check.
the actual argument#
it's not that software should be free. it's that the price should have something to do with the cost.
a teleprompter has almost no marginal cost. no inference, no storage, no bandwidth. when a product like that carries a subscription, the subscription is priced off how badly you need the flip, not off what the flip takes to provide. that's rent, and rent is what a category collects when nobody has shipped the free version yet.
so: the free version. mirror on both axes, voice-tracked scrolling, a Bluetooth remote, front-camera recording, six reading fonts, and the full beam-splitter workflow. no account, no tier, no trial that expires.
point it at the folder your scripts already live in and read.
