iSamurai

iSamurai is a browser-based suite for generating and editing images and transforming photos and video. It is best suited to creators and developers who need several media tools in one service. Choose it for its broad mix of image, face, character and motion features; check the video limits and credit reset rules before committing.

Overview

The range extends from prompt-based image work to video processing, with a REST API for developers who want to connect processing tasks to their own workflows. Free credits offer a way to try image features, but video face swap and head swap require a paid plan. The tier structure also matters: monthly credits reset each billing cycle, while daily-login bonuses and one-time booster credits do not expire.

Key features

Face swap works on photos, GIFs and videos, and Multiple Faces Mode can process several people in one image or clip. That makes the suite a stronger fit for varied media projects than a tool confined to single-face photos. Video access is tier-dependent: Kohai supports 480p with no length cap, while higher tiers raise resolution and some other limits. The stated one-minute maximum video length should be reconciled with the plan descriptions before choosing a tier.

Head swap replaces the entire head, including hair and head shape, and is paid-only. Character Swap replaces a person while preserving scene motion; Animate transfers motion from video to a still character. Free users get only a one-second 480p test clip for the character tools, so the free tier is a preview rather than a practical route to longer character work.

Imagine generates and edits images with text prompts, region inpainting and multi-image composition. Photo restoration and AI slow motion add useful adjacent tasks. Slow-motion ceilings vary substantially: Kohai, Kohai Maxi and Ninja reach 2×, Ronin reaches 4×, and Samurai offers up to 8×. That makes Samurai the clearest choice for users prioritizing slow-motion range.

The REST API uses API-key authentication and covers face swap, slow motion, image restoration and other processing tasks. It is a practical advantage for developers, though the plans give no separate API price. iSamurai says uploads are not used to train AI models, describes HTTPS/TLS, hashed passwords and API keys, and isolated processing containers. Media stays on the service until the user deletes it or the account; individual gallery files can be permanently removed upon deletion.

Pricing

The free plan costs nothing, billed $0/month, forever free. It provides 10 monthly credits and 10 more per daily login, photo face swap and restoration, image generation and editing, plus the one-second 480p character-tool test. Video face swap and head swap are excluded. It suits occasional image use and initial exploration, but the credit allowance and video restrictions make it a poor fit for regular video work. No credit card is needed to start.

Kohai costs $9.90 a month, billed $9.90/month or $89.91/year. It includes 150 monthly credits, 50 daily-login credits, 480p video face swap with no length cap, head and character swaps up to 10 seconds, and slow motion up to 2×. It is the entry paid tier for short, lower-resolution transformations. Kohai Maxi costs $15 a month, billed $15/mo or $135/yr, for 300 monthly credits with the same processing limits; it fits users who need more monthly volume rather than longer or higher-resolution clips.

Ninja costs $29 a month, billed $29/month or $261/year. Its 600 monthly credits and 60 daily-login credits accompany 480p, 60 fps video face swap with no length cap, head and character swaps up to 15 seconds at 480p, and 2× slow motion. Ronin costs $49 a month, billed $49/month or $441/year, and raises the allowance to 1,500 monthly credits plus 100 daily-login credits; it supports 720p video face swap, head and character swaps up to 30 seconds at 720p, and 4× slow motion. Ronin is the more capable fit when resolution and clip duration matter, while Ninja offers a lower-cost step up from Kohai.

Samurai costs $79 a month, billed $79/month or $711/year. It includes 4,000 monthly credits, 200 daily-login credits, video face swap up to 1080p with no length cap, head and character swaps up to 60 seconds at 1080p, high-quality mode, up to three extra reference photos and two videos processing at once. Its slow motion reaches 8×. Samurai Maxi costs $150 a month, billed $150/mo or $1,350/yr, with 12,000 monthly credits and the same stated limits. These upper tiers suit heavier workloads needing higher resolution, longer swaps or concurrent processing; the credit resets still make usage planning important.

Kunai costs $9.90, paid once for a 200-credit top-up, Katana costs $39, paid once for 1,000 credits, and Shuriken costs $59, paid once for 2,500 credits. Each is available only to paid subscribers, and top-up credits never expire. They can supplement a subscription without the monthly reset applying to those credits, but do not replace the paid-plan requirement for video face swap and head swap. Failed jobs are automatically refunded. A free trial is offered.

Platforms

iSamurai runs on web, Android and iOS, and offers an API. The browser-based suite suits users who want access without choosing a desktop operating system, while the mobile apps extend access to phones and tablets.

Who it's for

Content creators and meme or entertainment users can draw on the photo, GIF and video transformations alongside image generation and editing. Marketing teams and filmmakers may value the character and motion tools, but should match clip duration, resolution and credit volume to the right tier. Family archivists have photo restoration alongside creative tools. Developers have the API for integrating processing into applications or workflows. It is less suitable for someone who only wants a simple, low-cost video swap and does not need the wider suite.

Pros and cons

Broad media coverage: Photo, GIF and video face swap sit alongside image generation, restoration, character tools and slow motion.

Useful API access: API-key-authenticated processing can serve developer workflows as well as browser use.

Flexible credits: Daily bonuses and paid top-ups do not expire, and failed jobs are refunded; subscription credits do reset each billing cycle.

Free tier has a narrow video role: Video face swap and head swap require payment, and the character tools are limited to a one-second 480p test.

Plan limits require care: Resolution, swap duration, slow-motion range and monthly credit volume differ by tier, and the stated one-minute maximum video length sits alongside plan descriptions saying face-swap video has no length cap.

Alternatives

AI Face Swap Tools is the broader directory to consult when comparing options across the category. Remaker AI is worth considering for buyers who prefer credit packs that do not expire, including a 5.99 USD one-time 200-credit option. Avatarify is a lower-cost alternative for users focused on a mobile app, with a free app and a 3.99 USD monthly premium plan. LiveFaceSwap AI may suit users seeking live face-swap options across desktop platforms, with its Basic plan priced at $12 a month and billed $36 / 3 months.

YouInMeme is an alternative for users who want a small number of daily creations, with two free creations per day. AI Ease suits those looking for free basic image-related features, with a paid yearly membership. Jhroke Camera offers a free web-based Basic Mode with watermarked SD output and no commercial usage. Picsi.Ai is an alternative for single-face image swaps, with 10 daily free credits and GIF/video locked on its free tier. SwapFace may fit users seeking a one-time purchase, with its Basic plan at 9.99 USD once for benefits valid 30 days.

Verdict

iSamurai is a strong fit for creators and developers who want image tools, face and character transformations, motion processing and an API under one roof. Its breadth is the main reason to choose it; the tier-specific limits, resetting subscription credits and the tension between the stated video maximum and uncapped plan descriptions are reasons to compare carefully. If you need only occasional image work, start free; for regular video or higher-resolution swaps, choose a paid tier by its clip and credit limits rather than its headline price alone.
