## Speedwrite

Speedwrite began as an automatic text generator for producing unique writing from source material and has evolved into an AI humanizer. Its premise is that AI drafting tools like ChatGPT, Claude and Gemini all produce the same recognizable voice, and readers have learned to spot it. Speedwrite takes that generic voice and rewrites it into prose that reads like a person wrote it, one paragraph at a time.

The mechanism matters: unlike paraphrasers that act like a thesaurus with a randomizer and swap words while keeping sentence structure, Speedwrite rewrites whole sentences, reorganizing ideas and varying sentence length and rhythm. Press Predict again on the same paragraph and you get a different version, so two people working from the same input get different results. It also cleans up rough or ungrammatical English into clear, fluent writing while keeping the facts you supplied.

It is aimed at marketers, professionals, bloggers, SEO and social teams, and non-native English writers who draft with AI and want the output to sound less templated. A free account lets you start rewriting, with subscription plans for heavier use. The tool reads and writes English.

**Pricing & Plans:** Speedwrite is free to try: create an account and start rewriting. Subscription plans are available when you need more capacity. See the site for current plan details.

- **AI humanizer rewriting:** Rewrites AI-generated paragraphs so they read like a person wrote them, not a chatbot.
- **Paragraph-level regeneration:** Each press of Predict produces a new version with different sentence shapes and rhythm.
- **Sentence-level rewriting:** Reorganizes ideas and varies sentence length rather than swapping individual words.
- **Rough-draft clean-up:** Turns messy or ungrammatical English into clean, fluent writing while keeping your facts.
- **Multi-source input:** Works on text from ChatGPT, Claude, Gemini, an old article or your own notes.

**Strengths:** Rewrites whole paragraphs rather than swapping synonyms; Produces a different version on every press of Predict; Works on text from any AI chatbot or your own notes; Useful for cleaning up messy drafts and non-native English

**Limitations:** Currently English-only; It is a prediction, so you should read and fix output before use; The site also carries affiliate buying guides, which can feel off-topic

## 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
