Most teleprompter apps look identical in a screenshot: big text, a scroll speed, a record button. The differences only show up once you are standing in front of a camera with something to say, which is a bad time to discover them.

Here is what actually separates them.

Does it follow you, or do you follow it?

This is the big one. A fixed scroll speed means you spend the take keeping up rather than speaking. Look for voice following — text that moves at the speed you are talking. Everything else on this list matters less.

Can you read it comfortably?

Check the font choices, not just the size. Faces designed for reading ease make a real difference over a long script, and if anyone on your team is dyslexic it is not a nice-to-have. Talk2Camera includes Lexend and OpenDyslexic for exactly this reason.

Does it record, or just prompt?

Plenty of prompters are only prompters: you run a second app to record, and now you are managing two things at once and hoping neither drops a frame. A prompter that records is one fewer thing to go wrong.

What happens when you need the rear camera?

Most apps stop the recording. If your videos ever involve showing something, check this before you commit — it is the difference between one clean file and a stitching job. This is what mid-take camera switching exists for.

What does it do to your file?

Ask whether a plain trim re-encodes. Many apps re-encode everything, which costs a generation of quality for no reason. A good one tells you before you export whether it is copying your frames or making new ones.

What does it cost, and what is free?

Look for what the free tier actually does rather than how long it lasts. Recording, the prompter, trimming, captions and export are free forever in Talk2Camera; the paid tiers exist for things that cost us money to run, like 4K encoding and AI.

If you want to compare the whole list against what any given app does, the feature list says which platform does what, including where the two differ.
