## AltPlot

AltPlot turns fanfiction into an interactive, email-based experience. 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

## Undetectable AI

Undetectable AI focuses on a single practical problem: content that sounds machine-made can be penalized, flagged or distrusted. The platform's detector highlights which sentences a scanner would most likely mark as AI-generated, showing percentages before the humanizer even runs. Once flagged, the humanizer rewrites those segments with varied sentence structure, richer vocabulary and adjusted tone, aiming to keep the original meaning intact while producing writing that reads naturally.

Beyond the core text tools, the product range has expanded into media forensics. There are detectors for AI-generated images, voice, video and deepfakes, plus specialty utilities such as a fake PDF detector, a receipt checker and other document-verification tools. A Chrome extension brings detection and rewriting into Gmail, Google Docs and any other page you are typing on, and an API is offered for teams that want the humanizer embedded in their own workflows.

The platform reports more than 24 million users and supports 50+ languages, though English yields the most accurate results. Business Solutions add stricter data-retention controls, white-labeling and non-expiring credit packs for higher-volume clients. A free tier is available with limited words, and the vendor advertises a money-back guarantee when humanized output is still flagged.

**Pricing & Plans:** Freemium. A free trial covers a limited number of words (currently 250). Paid monthly plans start around $9.99 for 10K words and scale to roughly $42.50 for 50K words, while annual billing discounts those rates by about half (roughly $5.00-$21.25 per month). Custom business tiers add non-expiring credits, redistribution rights and priority support.

- **AI Detector:** Scans up to 5,000 words at a time and highlights the specific sentences most likely to be flagged as machine-written, so you can see your text the way a detector sees it.
- **AI Humanizer:** Rewrites AI-flagged passages with different sentence rhythms, vocabulary and tone, keeping your meaning while making the prose read like human writing.
- **Media authenticity checks:** Detectors for AI images, voice recordings, video and deepfakes, plus specialty document tools for checking whether a PDF or screenshot has been manipulated.
- **Chrome extension:** Detect and humanize directly inside Gmail, Google Docs or any web page without switching tabs.
- **API and business options:** An API lets teams plug humanizing into existing pipelines, while business plans offer white-labeling, higher volumes and non-expiring credits.

**Strengths:** Detector and humanizer live in one workflow, so you can flag and fix text without switching apps; Wide language coverage (50+ languages) with strong English accuracy; Extra media tools (image, audio, video, deepfake, fake PDF) beyond plain text; Chrome extension makes it usable inside the tools people already write in

**Limitations:** Detector results are probabilistic and can disagree with other detectors or with human reviewers; Free tier caps out at roughly 250 words, so any real workload needs a subscription; Word limits still apply even on paid tiers, so heavy publishing volumes require enterprise pricing; Humanized output sometimes needs a light manual edit to preserve nuance and technical accuracy
