NSFW AI video generator options for adults: text prompts only, no photo uploads

An NSFW AI video generator is the riskiest tool in this niche. A feature that animates an uploaded photo can turn a picture of a real person into sexual video in seconds, so this page applies the strictest rule we have: a clip may start only from a text prompt or from an image the service itself generated. No uploads, no exceptions.

Three services pass, and the list may stay short. They are listed by how clearly the video workflow and the upload ban are documented, then by how openly clip costs are published.

• Nastia AI. Best for: The most clearly documented text-to-video workflow. The help center describes text to video as creating a short clip from a description, and image to video as animating one of your own generated images. The compliance page states that "Image and video uploads are disabled, and prompts naming public figures are refused." Prices are shown only after sign-in, and purchases are non-refundable except where law requires or a technical error prevented delivery.
• Secrets AI. Best for: Video alongside a memory-focused companion. The cheapest clip mode costs a fixed 600 Moments for 8 seconds, so a Premium grant of 8,000 Moments covers around 13 basic clips a month. The Privacy Policy states that users cannot upload files or images and that all images and videos are generated by the platform. The free tier has no video generation.
• Candy AI. Best for: Short clips as part of companion chat. Candy AI generates short videos of its characters and accepts no uploads, according to the Blocked Content Policy, which also bans images intended to resemble actual persons. Video costs tokens from the 100-token monthly allowance, but per-feature costs are not published on public pages, so the number of clips a month cannot be estimated.

There are two ways an AI service can make a clip:

• Text-to-video creates motion from a written description. Nothing real goes in, so nothing real comes out.
• Image-to-video animates a still picture. That is harmless when the picture was generated by the same service from a text prompt. It is dangerous when the picture is an uploaded photo, because the photo can show anyone.

This page accepts the first, and the second only for images the service generated itself. Nastia AI documents both modes and limits image to video to your own generated images. Secrets AI and Candy AI do not accept photo uploads at all, so their clips cannot start from a real photo. Their public pages do not describe the video workflow step by step; what is documented is the upload ban, quoted below.

The same three rules as for image generators apply here, with one addition: no photo-to-video, face swap or video-restyling feature that starts from user material.

1. Fictional adults only. Each service bans content involving or resembling minors in its own terms. Nastia AI names "childlike or "aged-up" characters" explicitly.
2. No uploads of other people's photos or faces. The rules we relied on:
   • Nastia AI: "All imagery and video are generated by AI. Image and video uploads are disabled, and prompts naming public figures are refused." The Synthetic Media Policy adds that the service "does not accept user-imported, uploaded, or external photographs as face references".
   • Secrets AI: "You cannot upload files or images to the Service". Prohibited: "Deepfakes or simulated intimate imagery of real individuals".
   • Candy AI: "Although users cannot upload or share content on the Services, ... We have a zero-tolerance policy for the creation or attempted creation of non-consensual intimate imagery and images intended to resemble actual persons ("deepfakes")."
3. No consent checkboxes. A service that lets you upload someone's photo after ticking "I have consent" does not pass, because the consent cannot be checked.

Many services with video features failed at least one rule. The common reasons were picture-to-video from an uploaded photo, tools that transform a video the user supplies, likeness uploads allowed with a consent prompt, real-person bans that skip public figures, terms that admit users under 18, and public catalogs that surface age-ambiguous tags. When another service documents text-to-video with a written upload ban, it can be added.

Secrets AI is the only service here that publishes a per-clip cost: 600 Moments for an 8-second basic clip, with 8,000 Moments a month on Premium ($19.99) and 15,000 on Ultimate ($39.99). Nastia AI shows plan prices only after sign-up and publishes no video cost. Candy AI's Premium includes 100 tokens a month, but per-feature costs are not public. None of the three lists video on its free tier.

Video is the most expensive feature on every service here. On Secrets AI, a top-up of 4,000 Moments costs $11.99 in the wiki's example. Unused grant Moments do not roll over, and Candy AI tokens expire when a subscription ends.

Video generation is where a budget runs out fastest, so read the refund terms before buying a top-up:

• Nastia AI: "All purchases are non-refundable, except where required by law or where a technical error prevented delivery."
• Secrets AI: spent and purchased Moments are not refunded except for billing errors; EU and UK users have a 14-day withdrawal right, reduced by what was used.
• Candy AI: a subscription refund only within 24 hours of payment, only for card payments, and not if more than 20 tokens were used.

Nastia AI stores generated media with its prompts, has no public feed, and lets you delete videos at any time. Secrets AI lists model training among data uses and deletes chat history immediately on account deletion. Candy AI may use de-identified chats for training and keeps account data for about three years after your last activity unless you ask for deletion. None of these statements means a third party never sees your prompts, so keep real names and identifying details out of them. More in the AI companion privacy guide.

• You want to see how video is made before paying: Nastia AI documents the workflow most clearly.
• You want to know exactly how many seconds you get: Secrets AI publishes per-clip costs.
• You mainly want a companion and an occasional clip: Candy AI or Secrets AI.

If a service you are considering offers to animate a photo you upload, treat that as a reason to look elsewhere, whatever its marketing says.
