## FormalizeIt

FormalizeIt targets a very specific annoyance: you know what you want to say, but the draft in your compose window sounds blunt, careless or too casual for the recipient. The add-on drops a button into Gmail's compose toolbar; press it and your text is sent to OpenAI, which returns a rewritten version that reads as more professional and more respectful while keeping the original intent. It is deliberately minimal — there is no dashboard, no template library and no tone picker, just one action on the draft you already wrote.

Because the extension uses OpenAI directly, you register with OpenAI and paste your own API key. That means your usage is billed by OpenAI rather than by the developer, and the extension itself can be installed at no cost. The trade-off is that you need an OpenAI account and basic comfort with API keys before it is useful.

The listing is small and has not been updated since August 2023, so treat it as a single-purpose utility rather than a maintained email suite. It handles the common case well: quick politeness and professionalism upgrades on short business emails, replies to managers or clients, and any situation where an informal draft needs to be presentable before it goes out.

**Pricing & Plans:** The extension is free to install. You supply your own OpenAI API key, so any model usage is billed by OpenAI at their standard API rates; the developer does not charge a subscription.

- **One-button rewrite in Gmail:** A magic-button action is added to the Gmail compose window, so you can rewrite the draft you are already writing without switching tabs or copying text elsewhere.
- **Professional and polite tone output:** The rewrite targets professionalism and respect, turning terse or overly casual phrasing into wording better suited to colleagues, managers and clients.
- **Powered by your own OpenAI key:** You connect the extension to OpenAI with your own API credentials, keeping usage costs transparent and under your control.
- **No learning curve:** There are no settings to configure beyond the API key and no new writing interface to learn — it works inside the Gmail compose box you already use.
- **Chrome-native install:** Installs from the Chrome Web Store as a small extension with a light footprint, and the developer discloses that it does not sell or misuse your data.

**Strengths:** Free to install and stays inside the Gmail compose window; Requires no new writing tool or workflow to learn; Uses your own OpenAI key, so costs stay transparent; Developer discloses that data is not sold or reused outside core functionality

**Limitations:** Requires an OpenAI account and a manually configured API key; No tone, length or style controls — one fixed professional rewrite; Last updated in August 2023 and has very few users, so long-term maintenance is uncertain

## ZeroGPT

ZeroGPT is best known as an AI content detector, but the site has expanded into a full writing and verification toolkit. The core AI/GPT detector lets you paste text or upload a file and returns a highlighted analysis showing which sentences look machine-written, with a percentage gauge and an automatically generated PDF report you can use as documentation.

Around that core sit several companion detectors and writers. The AI image detector and AI video detector extend checking beyond text; the plagiarism checker scans against billions of sources; and the AI humanizer and paraphraser rewrite text into a more natural style. A grammar checker, summarizer, translator, dictionary, word counter, citation generator, and AI email helper round out day-to-day writing tasks. The company says its multi-stage DeepAnalyse model is trained on internet text, educational datasets, and proprietary synthetic AI datasets, covers over 35 LLM families, and reports 98.4% detection accuracy with a false positive rate under 1%.

Access is freemium: the main tools work free in the browser, with MAX and EXPERT subscriptions for heavier use and premium features, and a separate API for organizations that need large-scale integration. ZeroGPT also runs on WhatsApp and Telegram through a bot, letting you chat, detect AI text, summarize, paraphrase, translate, and check grammar without leaving the messaging app.

**Pricing & Plans:** Freemium with paid tiers. Core tools such as the AI detector, summarizer, and grammar checker are usable free in the browser, while MAX and EXPERT subscriptions unlock higher limits and premium features, and API access is sold separately for organizations.

- **AI and ChatGPT detection:** Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report.
- **AI image and video detection:** Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals.
- **Plagiarism checking and humanizing:** Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning.
- **Writing and productivity tools:** A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer.
- **API for organizations:** A documented REST API exposes detection, plagiarism, paraphrasing, summarization, grammar, chatbot, and translation endpoints for organizations that need to embed ZeroGPT at scale.

**Strengths:** Free browser access to the core AI detector, summarizer, and grammar checker; Sentence-level highlighting with an overall percentage and exportable PDF reports; Extends beyond text to AI image and video detection, plus plagiarism checking; Broad companion toolkit: humanizer, paraphraser, translator, dictionary, citations, email helper

**Limitations:** AI detectors can produce false positives, so results should be treated as a signal rather than proof; The strongest features sit behind MAX/EXPERT paid tiers and API access is a separate purchase; Character limits apply to the free detection box; No detection tool can guarantee correctness across every model and language
