Instead of browsing a static archive, you describe what you want — the relationship between the characters, such as friends, enemies, romantic, siblings or parent-child — and submit a request. Within 24 hours a custom-written first chapter arrives in your inbox. The story does not stop there. You reply to the email with your input, choosing from predefined buttons or writing free text to steer where the narrative goes, and a continuation arrives within another 24 hours. That loop can repeat as many times as you want, so the plot develops according to your decisions rather than a fixed script. The first chapter is offered free, and the account area refers to an 'Altplot Unlimited' subscription for readers who have already received chapters and want to keep going. The project is built by a small independent team. **Pricing & Plans:** AltPlot offers the first chapter for free. Continued stories are tied to an 'Altplot Unlimited' subscription mentioned in the account area; the site does not display a public price list. - **Custom-written stories:** Each chapter is written specifically for your request rather than pulled from a shared library, with the relationship dynamic you choose. - **Email-based interaction:** You receive chapters by email and reply directly to influence the story, so no separate app or login flow is needed to keep reading. - **Flexible input modes:** Steer the plot either with predefined buttons for quick choices or with free text when you want to describe something specific. - **Fast 24-hour turnaround:** Both the first chapter and each requested continuation are delivered within a 24-hour window. - **Unlimited continuations:** The interaction loop can be repeated as many times as you like, letting the narrative grow indefinitely under your direction. **Strengths:** Truly bespoke chapters rather than generic template stories; Simple email workflow with no complex interface to learn; Fast delivery promise of 24 hours per chapter; Free first chapter to try before subscribing **Limitations:** Pricing for ongoing stories is not published on the site; Delivery time depends on demand and takes up to a day per chapter; Available only in an email-based format; Text output quality depends on the underlying generation and editing process [Profile (Markdown)](https://openaitools.app/tool/altplot.md) ## PromptBase PromptBase occupies the 'prompt layer' of the AI stack. As generative models became widely available, the hard part shifted from access to knowing what to type, and PromptBase turned that gap into a marketplace. Buyers get tested wording that reliably produces a particular result; sellers get paid for prompt engineering work they would otherwise give away. The catalogue is broad rather than deep in any single niche. There are categories for art styles, portraits, product shots, logos, icons, apparel designs, marketing copy and even prompts intended to help build small apps or landing pages. Each listing is tied to a specific model family, which matters because a prompt tuned for one image model often behaves differently in another. As a marketplace, PromptBase's value depends on its community. Sellers are incentivised by revenue share, which keeps fresh prompts coming, while buyers rely on sample images and seller reputation to judge quality before purchasing. The model is paid rather than free, and the site runs behind standard bot protection. **Pricing & Plans:** Paid marketplace. Most prompts are sold individually at low per-item prices set by their creators, with subscription options available for buyers who want ongoing access or credits. Pricing is not disclosed on the public page and may vary by listing. - **Curated prompt catalogue:** Thousands of ready-to-use prompts organised by model and by output type, from illustration styles to marketing copy. - **Model-specific sections:** Listings are grouped by the model they were built for, so you can filter to the tool you actually use. - **Sample output previews:** Each prompt is shown with example outputs, making it easy to judge the style before spending anything. - **Creator seller programme:** Anyone can upload prompts for sale and earn revenue share on every copy sold. - **Pay-per-prompt or subscribe:** Low per-prompt pricing plus buyer subscription options cover both occasional and high-volume users. **Strengths:** Saves time you would otherwise spend on trial-and-error prompt writing.; Sample images make quality easier to judge before buying.; Organised by model, so findings map to the tools you already use.; Creators can monetise prompt work directly. **Limitations:** There is no free tier for buying prompts - you pay per prompt or subscribe.; Quality and usefulness vary between sellers, so results depend on the individual listing.; A prompt that works well in one model is not guaranteed to behave identically elsewhere.; Popular prompts are widely sold, so exclusivity is limited.
