NoLang Video manuals 
Without filming or recording, NoLang creates videos that show the pages of your procedure document while an AI voice explains the steps.
Choose "Explain all pages" and NoLang explains every page of your procedure document in order, without skipping.
You can fix the pronunciation of internal terms and machine names word by word and register them in the dictionary.
When a procedure changes, fix the script and confirm. People can watch the new version from the link you shared.
HOW IT WORKS
You can use procedure document and manual PDFs and PowerPoint (PPTX) files as they are. Word and Keynote files work once exported to PDF or PPTX.
STEP 01
Add your procedure document as a PDF or PPTX, and write who the video is for.
STEP 02
Choose whether to explain all pages, specify a script, or another method, then pick a voice and presenter.
STEP 03
Review the finished video, fix the script and subtitles, then distribute it with a share link or export it as MP4.
FROM PROCEDURE TO VIDEO
NoLang builds the video's structure and script from the pages of the procedure document you add. You choose how much of the procedure to explain, and in what wording, from four creation methods.
Explain every step without skipping pages Explains every page of your procedure document in order, without skipping. Suited to tasks where no step can be missed.
Read the script you wrote, exactly as written Write a narration script for each page, and NoLang reads it exactly as written. Suited to procedures where you don't want the approved wording changed.
Use your PowerPoint notes as the script NoLang reads the explanations you wrote in your PPTX speaker notes as the script, as written. PDF files are not supported.
Pick the key pages and keep it short Suited to short videos that give an overview before starting a task. You can choose lengths starting from 30 sec.
Shows which task the procedure is for, right at the start.
Explains what the task is for and who does it.
Checks tools, protective equipment, and materials before starting the task.
Shows how many stages the task has, up front.
Explains the steps one by one, in page order.
Explains why it is done that way, together with the step.
Shows what not to do, right next to the step.
Shows and reads aloud the criteria values, such as tightening torque and time.
Shows how to check that the task is complete.
With "Explain key points only," AI chooses which pages to use based on the content of your document. The table above is one example.
You can review and fix the finished script before publishing.
SHOOT ON YOUR PHONE
For tasks that don't have a procedure document yet, you can create from footage shot on a phone. Upload the video and choose a method, and AI turns it into a video manual with subtitles or narration.
Choose by how you filmed
Transcribes what you said while working and turns it into subtitles as is. You can set the transcription language and the number of speakers.
Method in the app Transcribe and add subtitles
Adds AI narration that matches the footage. The original audio is not used, so it also works for footage with machine noise.
Method in the app Add narration
Transcribes your footage and keeps only the key scenes in a short digest video.
Method in the app Summarize into a digest
Film the task on your phone. MP4, MOV, and WEBM videos are supported.
Upload your video under "From video" and choose how to create it. You can also describe what you want in text.
Review the finished video, then distribute it with a share link or export it as MP4.
FILM ONLY WHAT MOVES
You can combine both approaches in one video. Create the setup, order, cautions, and criteria from your procedure document, and add your own footage only for scenes where you want to show hand movements or how much force to use.
Assembly, inspection, cleaning, cooking, caregiving, and more
Business systems, apps, machine control panels, and more
Safety, hygiene, and quality standards, and more
After generation, add your footage with "Create scene from video" in the editor. You can also add arrows and callouts on top of the pages.
WHEN STEPS CHANGE
You don't have to remake the video from scratch every time a procedure changes. Just fix the script and confirm, and the video becomes a new version.
In the editor, rewrite the script for the steps that changed. You can also fix images and subtitles.
Use "Regenerate audio" to regenerate the narration for that scene. Audio can be regenerated scene by scene.
Press "Confirm this content" and the video is regenerated as a new version.
Viewing, the share link, and downloads switch to the new version. The video URL stays the same.
The day you revise your procedure document, your video can move to a new version too
Editing is done on a PC. Until you confirm, the shared video stays on the previous version.

LANGUAGES
With "Convert language," you can create a video in another language with the script and on-screen text translated. The original video stays, so you can compare the same procedure in two languages.
Supports 34 languages, including Vietnamese, Indonesian, Tagalog, Nepali, Burmese, Chinese, and English. The available voices depend on the language.
The narration and subtitles are in the language you choose. Images on your document pages and text inside slides are not translated.
You can fix the translated script in the editor. For safety-related procedures, it's best to have someone who knows the language check it.
