If you're looking for a teleprompter that adapts to your reading speed and helps with eye contact, SpeakAide is a good option. This AI-powered tool marries advanced teleprompter technology with an AI script generator. The teleprompter displays text on a screen at a speed you set, so you can concentrate on your audience without worrying about your script. That can help you overcome nerves and deliver a more natural tone to your presentation. The free version of the tool offers basic video recording abilities, but the premium version has more advanced editing abilities.
Another option is Descript, which seeks to make video and podcast editing as easy as editing a word processing document. Although it's more geared for editing, you can use the tool to edit for clarity and excise filler words, which can improve the quality of your delivery. This isn't a teleprompter per se, but the AI technology can help you improve your speaking and recording. Descript offers a free plan with limited features and paid plans starting at $12 per person per month.
