InVideo starts from a prompt: you describe a video and it assembles one from generated shots, stock, an AI voice and music. That is a real product, and it is not the same product as this one. Montaj is an InVideo alternative for the case where the footage already exists , you filmed it , and what you need is the subtitles written, the dead air gone and the audio cleaned, on your device, with nothing uploaded.
You have no footage and no intention of filming any. You want a video produced from a script, with generated shots, stock and an AI voice.
Choose Montaj if…
You filmed the video yourself and the work left is captions, cutting the pauses and cleaning the voice track.

The honest summary: InVideo wins whenever the raw material does not exist yet: script, shots, voice and music, all produced for you. Montaj wins whenever it does exist and is sitting on your device, where the remaining work is labour rather than creation.
Source material
Why people look for an InVideo alternative
The usual reason is not a missing feature. It is a mismatch: someone arrives with a clip they filmed on their phone and finds a tool designed to invent one. Generated shots and an AI narrator are not much use when the whole point is that it is you on camera.
Montaj assumes the opposite. Your face, your voice, your room, your device, and the AI is pointed at the chores instead of at the content. Nothing is uploaded to make that happen.
Winner: Montaj when the footage already exists
Privacy
InVideo vs Montaj on where the work happens
InVideo runs in a browser and on its own servers, which is the only way a generation pipeline of that size can work. Montaj runs its models on your device.
On-device transcription, then word-by-word karaoke subtitles with word-level timing.
One-tap silence removal across the clip, reversible and non-destructive.
Neural audio denoising tuned for voice, no upload involved.
Fully offline once the models are cached. The one-time model download is the only network call.
Winner: Montaj. Your video never leaves your device
Honest limits
Where InVideo wins
If the video does not exist, Montaj has nothing to offer you. InVideo will write the script, choose or generate the shots, narrate it and score it, in a browser or on a phone, with a team watching if you want one.
Montaj has no generation of any kind, no stock, no synthetic voice, no templates. It is vertical 9:16 only, single-user, and does not yet save projects, closing one loses it.
Winner: InVideo, when you have nothing to edit yet
The verdict
These two are not substitutes, and picking between them is really picking what kind of video you are making. If you have nothing filmed and you need something on screen by tomorrow, InVideo writes it, generates it and voices it, and Montaj is useless to you. It has no footage to work with. If you did film it, and the job is captions, dead air and a voice that sounds like a room rather than a microphone, generation is beside the point.
It depends which half you want. For generating video from a prompt, InVideo is the tool and Montaj is not a substitute. For editing footage you filmed , captions, silences, audio , Montaj is the strongest on-device InVideo alternative, free and with no watermark.
Does InVideo edit my own videos?
You can bring your own media in, but the product is built around producing video from a prompt or a script rather than around detailed editing of your footage.
Can Montaj generate a video from a script?
No. Montaj has no video generation, no stock library and no synthetic voice. It edits footage you already filmed.
Is there an editor that works without uploading my footage?
Montaj runs transcription, subtitles, silence removal and audio denoising on your device, so nothing is uploaded, and it works offline after the one-time model download.
