## pdf.net

pdf.net positions itself as a single browser tab that replaces a stack of desktop PDF utilities. Upload a file — or pull one in from Google Drive — and you can edit text directly on the page, drop in images, sign, annotate, redact, watermark, protect with a password, merge, split, rotate, reorder or Bates-number the document without installing anything. A converter section spans roughly thirty pairings, moving between PDF and Word, Excel, PowerPoint, CSV, JPG, PNG, HEIC, EPUB, Markdown and plain text, including niche jobs like pulling bank statements into spreadsheets.

Alongside the classic utilities, the platform exposes a compact AI layer. Chat with PDF lets you ask natural-language questions about an uploaded document, the PDF Summarizer condenses long files into key points, Generate PDF turns a written description into a formatted document, and AI Form Filler reads an existing document to populate a form's fields. These AI options are the reason the product also appears in AI writing and summarizer directories, though the bulk of the value is still conventional PDF tooling.

It is an independent product rather than an official Adobe or Google offering, and the site states that data is encrypted with AES-256 at rest and TLS in transit on Google Cloud, with files retained in your account until you delete them. The interface is mobile-friendly and available in several languages.

**Pricing & Plans:** Freemium with a subscription for output. Uploading, editing, signing and rearranging a PDF can be done without an account, but downloading a finished file or running a conversion requires a pdf.net subscription. Exact plan prices are shown on the site's own pricing page.

- **Full PDF editing toolkit:** Edit text, fonts, sizes and colours directly in the document, insert images, add page numbers, watermarks and Bates numbering, rotate, extract or rearrange pages, and split or merge files.
- **Broad format conversion:** Convert between PDF and Word, Excel, PowerPoint, CSV, JPG, PNG, HEIC, EPUB, Markdown and text, including bank-statement-to-spreadsheet and PDF comparison workflows.
- **Signing, security and redaction:** Type, draw or upload a signature, request signatures by email, add password protection, black out sensitive content and make flat or scanned forms fillable.
- **AI document tools:** Chat with a PDF to ask questions about its contents, summarize a long document into key points, generate a formatted PDF from a description, or have AI populate a form automatically.
- **Privacy and cross-platform access:** Files are encrypted with AES-256 at rest and TLS in transit on Google Cloud, and the editor works the same on desktop, tablet and phone with Google Drive import.

**Strengths:** Very wide feature set covering editing, conversion, signing and security in one browser tab; Editing, signing and page management can be tried without creating an account; AI features such as chat, summarization and form filling sit alongside practical PDF utilities; Responsive interface with Google Drive import and support for unusual input formats like HEIC and Markdown

**Limitations:** Downloading or converting a file requires a paid subscription, so free use is limited to in-browser editing; Large files and longer conversions depend on server processing time; The AI toolset is smaller than the number of classic PDF utilities, so it is not a dedicated AI document assistant

## 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
