Best AI tools to swap
anything in a video in 2026
Six tools that replace a person, a product or a setting in a clip you already have, side by side: what each one does, what it costs to start and what you get free. Facts are sourced from each vendor's own page, with the date we read it.
For creators and sellers who reuse footage instead of reshooting
What to compare before you pick one
The same four questions apply to every tool on this page.
What you can swap
Inflyu, Luma, Pika and Higgsfield cover people, objects and settings. Runway Aleph is built around objects, and Akool Character Swap around people. Read the first column before you upload a clip.
What stays from your clip
Most tools say the original motion or timing stays. Inflyu also splits a clip at its cuts and edits each shot, so test a clip with several cuts if yours has them.
Subscription or per clip
Runway, Higgsfield, Luma, Pika and Akool sell monthly plans. Inflyu sells credit packs you pay for per clip, with a monthly plan as an option.
What the free tier covers
Free access ranges from a one-time bundle of credits to a watermarked plan to none at all. Read the free-tier column before you upload a clip.
How swapping in a video works in Inflyu
Three steps, and you see the price before you spend a credit.
Upload the clip
Add a video you have the rights to, and say what to replace: a person, an object or the background.
Add a photo or describe it
Give a photo of the new person, product or place, or describe it in words, and look at the free preview picture.
Check the price, then run
The editor shows the credits before you run it, and a failed run is refunded.
Side by side
We make Inflyu, so it is first and marked. Every other fact comes from the vendor's own page, linked in the cell and dated 24 Oct 2026. Prices change, so confirm on the vendor page before you pay.

What an Inflyu swap costs, by clip length
An object swap is priced per shot and length, so the figure here is the lowest: one shot, one edited frame. A person swap is a flat price by length. Dollar amounts use the Power pack rate, the cheapest per credit. The editor shows the exact credits before you run.
| Clip length | Object swap (from) | Person swap |
|---|---|---|
| 4s | 11 credits ($1.16) | 12 credits ($1.27) |
| 6s | 16 credits ($1.69) | 17 credits ($1.79) |
| 8s | 21 credits ($2.22) | 21 credits ($2.22) |
| 15s | 37 credits ($3.90) | 38 credits ($4.01) |

Questions
What is an AI video swap tool?+
It replaces a person, an object or the background in a video you give it with something from a reference photo or a description, while the rest of the clip stays as filmed. You upload the clip, say what to replace and what to put there.
Which tool is best for swapping something in a video?+
It depends on what you swap and how you pay. Runway Aleph, Luma Modify Video, Pika Swap Anything and Higgsfield Genjutsu sell monthly plans; Akool Character Swap focuses on people; Inflyu charges per clip. We make Inflyu, so check the linked vendor pages for the others.
How much does it cost to swap something with Inflyu?+
An object or background swap is priced per shot and length, starting at 11 credits for 4s, 16 credits for 6s, 21 credits for 8s, 37 credits for 15s. A person swap is flat: 12 credits for 4s, 17 credits for 6s, 21 credits for 8s, 38 credits for 15s. At the Power pack rate the shortest object swap is about $1.16.
Can I try Inflyu video swap for free?+
Partly. A new Inflyu account gets 20 free credits once, no card required, and running a job needs a verified email. A swap also gets a free preview picture first, and when the picture looks good, one free short video with a locked end. The full video needs a credit pack.
Is a video swap the same as a face swap?+
No. A face swap changes only the face on the person in the clip, while a video swap can replace the whole person, a product or the setting. For face-only tools, see the comparison of AI face swap video tools linked below.
Do I need a subscription for Inflyu?+
No. Credit packs are one-time purchases that start at $1.99, and pack credits never expire. If you would rather refill each month, monthly plans exist too, and unused monthly credits do not roll over.
How current are the competitor prices on this page?+
Each competitor fact links to the vendor page it came from and shows the date it was read, most recently 24 Oct 2026. Plans and credits change often, so confirm on the vendor page before you pay. If a fact could not be confirmed on a vendor page, it is left out.
What does Inflyu not do well?+
Object and background swaps run shot by shot only on a clip of 4 seconds or more, a person swap replaces the whole person rather than pasting a face, and small logos and fine print may not come out exact. You name what to replace in words, so a very crowded shot gives weaker results. Use only clips you have the rights to.
