## Side Reader

Side Reader is a Chrome extension that opens PDFs in the sidebar of ChatGPT, Claude and DeepSeek so you can read and interact with them side by side: summarize, translate, explain or ask about any passage without leaving the chat.

**Preços e planos:** Freemium. The core Chrome extension is available to install, with a paid upgrade for extended usage; check the extension listing for current limits.

- **Read PDFs beside the chat:** PDFs render directly in the sidebar next to the chat, so your document and the AI conversation are visible at the same time.
- **Summarize, translate and explain:** Summarize a whole document, translate it, or have passages explained in simpler terms using the AI you are already signed into.
- **Custom action button prompts:** Built-in buttons cover the common actions, and you can edit their prompts to make the AI respond in the format and tone you need.
- **Screenshot questions for non-selectable content:** Ask about charts, scans or regions that cannot be selected by taking a screenshot question instead.
- **Local storage and a proper reader:** Files stay local in your browser and are not stored by Side Reader, and PDFs keep zoom, page navigation and width controls.

**Pontos fortes:** Keeps the PDF and the AI conversation visible in the same window; Works with ChatGPT, Claude and DeepSeek rather than locking you into one model; Local-only file storage — documents are not kept on Side Reader servers; Customizable action prompts for repeatable workflows

**Limitações:** Requires an active ChatGPT, Claude or DeepSeek session to do the AI work; Chrome only — no Firefox, Safari or Edge-specific edition; Very new/small product, so the feature set is still evolving

## ZeroGPT

ZeroGPT is an AI content detection platform with a text AI detector, AI image and video detectors, AI humanizer, plagiarism checker, and a set of writing tools including paraphraser, summarizer, grammar checker, translator, and citation helper.

**Preços e planos:** 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.

**Pontos fortes:** 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

**Limitações:** 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
