## 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

## StealthWriter

StealthWriter is built around two steps: scan and rewrite. The detector highlights sentences that still read as AI-written, and the humanizer then rewrites the text to smooth those passages out. Because you can run the detector again afterwards, it works as an iterative loop rather than a one-shot button, which makes it more practical for longer articles where only a few paragraphs sound robotic.

The tool targets people who draft with large language models but publish under their own name: bloggers, marketers, copywriters and researchers. Output can be tuned by rewriting level and, at the sentence level, by picking from alternative phrasings. Processing is quick — typically a matter of seconds — and the free tier with 10 daily humanizations and 1,000 words per input is enough to test whether the tone matches your writing style. Paid plans raise both the daily allowance and the maximum input length, which matters if you humanize long-form content regularly.

StealthWriter is a service of AiVantage LLC. On privacy, the company states that text submitted for humanizing or scanning is not stored after processing, not shared with third parties and not used for training. It is best treated as a drafting and polishing assistant: it improves how naturally AI-assisted text reads, but you should still review facts, claims and citations yourself before publishing.

**Pricing & Plans:** Freemium. The free plan costs $0 and includes 10 humanizations and 10 AI scans per day with up to 1,000 words per input. Paid tiers are Starter at $20/month (50/day), Plus at $50/month (150/day), Pro at $100/month (350/day) and Scale at $400/month (2,000/day), each allowing 5,000 words per input, with discounts for annual billing.

- **AI text humanizer:** Rewrites AI-generated drafts with natural phrasing, rhythm and flow, and lets you pick light, medium or aggressive rewriting depending on how much change you want.
- **Built-in AI detector:** Scan text before and after humanizing to see which sentences still look machine-written, with colour-coded sentence-by-sentence highlights.
- **Alternative rewrites per sentence:** Click any sentence to see alternative rewrite options and fine-tune the output until it matches your own voice.
- **Fast batch processing:** Returns humanized text in seconds, with word limits per input ranging from 1,000 words on the free plan up to 5,000 words on paid tiers.
- **Volume-friendly quotas:** Daily allowances scale with your plan, from 10 humanizations a day on the free tier up to 2,000 a day on the Scale plan, for high-volume content workflows.

**Strengths:** Free plan lets you test the humanizer and detector at no cost; Detector and humanizer in one workflow makes quality checking easy; Sentence-level alternative rewrites give fine control over tone; Three rewrite strengths suit different content types

**Limitations:** Monthly quotas are metered per day, so bursty heavy users may hit limits; Humanised text still needs a human read-through for factual accuracy; Result quality varies by language and by how obviously AI-written the source is; No built-in grammar or plagiarism checker beyond the AI detector
