## Avoid.so

Avoid.so targets a very specific problem: you have text that was drafted by ChatGPT, Claude, or another model, and AI detectors are flagging it. The service runs that text through a humanization pass that restructures sentences, varies rhythm, and replaces phrasing patterns that detection models associate with machine authorship. The result is meant to read as if a person wrote it, while preserving the original claims and intent.

The workflow is simple and credit-based. You paste or upload your content, pick an output language and a quality or speed profile, then run the rewrite. One credit corresponds to one word, and different plans come with different monthly word quotas. The free account includes a starter pool of words with per-request caps, while paid tiers scale from tighter monthly allowances up to effectively unlimited processing with a queue after a high-speed threshold.

The company advertises accuracy claims such as a 99.8% bypass rate and supports 50+ languages. Whether that holds for your specific detector and content is best tested on your own samples before committing. As with all humanizers, read the rewritten text before you publish it, and be aware that using such tools may violate the academic-integrity or editorial policies of the institutions you are submitting to.

**Pricing & Plans:** Freemium. A free account includes a starter word allowance. Paid plans are billed monthly or annually (annual saves 50%) and range from a low-cost Basic tier with a modest monthly word quota up to an Unlimited tier; listed prices include roughly $4.99/month Basic, $14.99/month Pro, and $29.99/month Unlimited, with a lower effective rate on annual billing.

- **AI detector bypass:** Rewrites content to get past major detectors including GPTZero, Originality.AI, Turnitin, Copyleaks, ZeroGPT, and QuillBot.
- **50+ language support:** Humanizes text in dozens of languages while attempting to preserve cultural context and nuance in each.
- **Meaning preservation:** Aims to keep your original message, tone, and intent intact while altering surface-level writing patterns.
- **Fast batch processing:** Processes thousands of words in seconds, with an API for teams that need to humanize content at scale.
- **Multiple quality and pass-rate modes:** Lets you trade speed against a more aggressive rewrite depending on how strict the target detector is.

**Strengths:** Covers most of the popular detectors in one tool, so you do not need several accounts; Genuinely large language coverage at 50+ languages; Word-based credit model is predictable and easy to reason about; Free starter words let you test it against your own detector before paying

**Limitations:** Success rate claims come from the vendor and will vary by detector and content type; Using humanizers can breach academic-integrity or editorial policies, so check the rules that apply to you; Still worth reading the output; aggressive rewrites can flatten your writing style

## 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
