Frequently Asked Questions

What is Mastersly?

Mastersly is a premium AI writing tool for adult erotic fiction. Unlike large language models trained on massive datasets, our model Eros 2 was trained on a select group of public domain stories and content written specifically to help train the model. The result is a focused, high-quality writing assistant for one purpose: creating erotic fiction.

How does the credit system work?

Credits are used to generate stories. The cost depends on the length:

• Short: 1 credit
• Medium: 2 credits
• Long: 4 credits

New users receive 20 free credits after completing age verification.

Do I have to pay to use the models?

You get 20 free credits to try the service after completing age verification. After that, credits can be purchased with Bitcoin or Lightning.

Do you store my stories?

No. Your stories are stored only in your browser's local storage. We never save your prompts or generated content on our servers. Clearing browser data will remove your stored story, so always download your work if you want to keep it.

What payment methods do you accept?

We accept Bitcoin and Lightning Network payments only. This helps protect your privacy.

What content is not allowed?

Our moderation system blocks content involving minors, non-consensual scenarios, real animals, incest between blood relatives, and extreme violence combined with sexual content. See our Terms of Service for details.

My prompt was rejected. What do I do?

If your prompt was incorrectly rejected, a small prompt will appear offering to report it as a false positive. Click Report to send it to our team for review. This helps us improve moderation.

How do I continue a story?

After generating your first part, use the Continue Story button to add more. You can add instructions in the prompt box before clicking Continue to guide the direction (e.g., "Now have them move to the bedroom" or "Include more dialogue").

How do I edit or redo a part?

Each story part has action buttons:

• Redo - Regenerates the part using the same prompt for a different take
• Edit - Loads the prompt into the editor so you can modify it, then click Replace
• + After - Inserts a new continuation after that specific part

What's the difference between length settings?

Length affects both output size and credit cost:

• Short (1 credit) - Quick scenes, single encounters
• Medium (2 credits) - Detailed scenes, longer narratives
• Long (4 credits) - Extended outputs with more depth and detail

Can I insert content in the middle of my story?

Yes! Use the + After button on any part to insert a new continuation after it. This is useful for adding scenes in the middle of your story without regenerating everything.

How do I verify my age?

After registering, you'll be prompted to upload a photo of your government-issued ID. Our system uses OCR to verify you're 18 or older. The process is automated and typically completes within seconds. If automatic verification fails, your ID may be queued for manual review.

Why do I need age verification?

Age verification is required to comply with laws regarding adult content. This protects minors from accessing inappropriate material and protects the service legally. We take privacy seriously - your ID is processed securely and not stored after verification.

How do I buy credits?

From your Dashboard, click "Buy Credits" to see available packages. We accept Bitcoin and Lightning Network payments via BTCPay Server. This provides privacy and avoids credit card processor restrictions on adult content.

• Starter: 175 credits for $15
• Standard: 400 credits for $30
• Author: 800 credits for $50 (best value)

Are refunds available?

Credits are non-refundable by default due to the nature of digital services. If you experience technical issues that prevented you from using purchased credits, contact support@mastersly.com and we'll work with you on a case-by-case basis.

How do I write better prompts?

Better prompts lead to better stories. Try to:

• Be specific about characters: names, appearances, personalities
• Set the scene: location, time, mood, circumstances
• Specify what you want: particular acts, pacing, tone
• Request style elements: "include dialogue," "focus on emotion"

Why is my generation shorter than expected?

Generation length depends on your selected preset. If you're getting shorter output than expected, try the Long preset (4 credits) which produces extended outputs with more depth and detail. Also, very specific prompts sometimes conclude naturally before reaching the maximum length.
