rtex: turn a script into a reel with Nei’s real avatar and automatic review
rtex turns a script into a vertical 9:16 reel with multiple segments, Nei’s real avatar, and automatic review.
rtex is an INEMA tool that turns a script into a reel: a short vertical video about a single topic. The presenter is Nei’s real avatar, made with HeyGen. The video combines on-screen panels, captions that highlight each word as it is spoken, and a closing card with an opinion question. Before publication, a validator, an automatic critic, and a quality check review the script and video.
For people creating content, rtex organizes the message into stages: it opens with an idea, shows evidence with a source, explains the steps of a method, includes a caveat, and ends with a summary line and a question for the audience. This gives the reel a defined format and helps check that each part is in order. The code is open to study and adapt, but making a video requires installed tools and your own HeyGen avatar.
To get started, you can use the HeyGen studio with your avatar and voice. If you already have a video of yourself or your avatar speaking the script, you can use that option and skip the studio; the spoken content must match the script by at least 85%. Keep in mind that setup depends on software and resources installed on the computer, and the avatar step can take minutes or hours. The rtex guide explains the steps.
