ToolAI Editorial · Checked on the official site on November 4, 2026 · 18+ adult content tool
AI Smut Writer is an adult-only AI fiction tool: you describe a scenario and characters, and the AI writes an erotic story that you can keep steering, edit or regenerate. The site labels itself 18+ Only · Adult Content. This guide does not reproduce explicit material; it explains how the product is organised, what the free daily credits cover and how to spend them sensibly. The tool profile and official link are on our AI Smut Writer page.
1. Story Mode vs Chat Mode
The top navigation offers two ways to work. Story Mode produces narrative prose from your prompt, and you can then ask for changes such as a different direction, more detail or a rewrite of one passage. Chat Mode is turn-by-turn interaction with a character. Below the prompt box the homepage offers four starting points:
- Smut Writing – write a scene or story from a short premise.
- Character Creation – build a character profile (background, personality, dynamics) before writing.
- Plot Brainstorming – generate premise and plot ideas.
- Editing Assistance – revise or polish a draft you already have.
2. The six writing models and their costs
The model selector in the prompt box lists six styles. Each shows a number, which is the credit cost per generation; heavier, more descriptive models cost more. A Thinking toggle sits next to the selector.
| Model | Style (as labelled) | Credits | Runs on 6 daily credits |
|---|---|---|---|
| Spark | Concise & Direct | 2 | 3 |
| Ember | Clean & Straightforward | 2 | 3 |
| Pulse | Fast & Raw | 2 | 3 |
| Velvet | Sensual & Intense | 3 | 2 |
| Muse | Elegant & Emotional | 4 | 1 |
| Ember Elite | Rich & Immersive | 5 | 1 |
The last column is simple arithmetic. Check the cost shown in the app before each run, because model names and prices can change.
3. Daily free credits and paid credits
On November 4, 2026 the homepage said: "Sign up now and get 6 free credits everyday", with "No credit card required". Earlier descriptions, including ours, mentioned 5 daily credits, so the allowance has changed at least once. If you need more than the daily refill, the site sells additional credits; we did not make a purchase and are not quoting a price.
Two practical points follow from the table: six credits give three short runs on a 2-credit model or one run on Ember Elite. Drafting on a cheap model and switching to a richer model only for the final scene stretches the free allowance furthest.
4. A practical first session
- Write a one-paragraph premise: setting, two or three fictional adult characters, tone and point of view.
- Use Character Creation first if the characters matter to you; a short profile keeps names and personalities consistent later.
- Draft on a 2-credit model (Spark, Ember or Pulse).
- Steer instead of regenerating: a specific instruction ("slow the pacing", "switch to her point of view") usually gets closer than a blind regeneration.
- Save what you like outside the site if you want a permanent copy.
5. Privacy and responsible use
The site states that "your stories and preferences remain completely private." That is the operator's claim; read its privacy policy for what is stored and for how long. A few rules worth following with any adult AI writer:
- Use fictional characters only. Do not write sexual content about real, identifiable people.
- All characters must be adults.
- Leave out your real name, workplace and other identifying details.
- Do not use a shared or work device.
