## note.md

note.md positions itself as an "academic IDE" for researchers. Rather than juggling Zotero for references, Obsidian for notes, a PDF reader for papers and a separate writing app, it puts sources, highlights, notes and citations in the same window. PDFs are imported into a source library, highlights and annotations stay attached to the exact passage, and citations can be generated as BibTeX or APA straight from PDF metadata with a link back to where the highlight came from.

The app stores everything as GitHub-flavored markdown files on disk, supported by LaTeX math, complex tables and bidirectional links that build a visual knowledge graph you can also export in a Neo4j-friendly format. Writing happens in a block-based editor with slash commands for citations, source images and links, so the act of writing continuously expands the graph of your reading.

Its differentiator is privacy and local AI. Semantic search, automatic indexing of figures and tables, Matrix extraction (filling research tables from your library) and Evidence Scan (checking a claim against supporting and contradicting passages) all run on-device using local models. The developer is explicit that nothing you read or write is uploaded. The company is ARSoftware UG, based in Germany, and the app is distributed through the Mac App Store; note.md is currently macOS-only and a younger product than the established alternatives.

**Pricing & Plans:** Freemium via the Mac App Store. The full writing workspace — local markdown editor and vault, Reading Studio, smart citations, source management and Graph View — is free forever. Premium unlocks the local-AI workflows (semantic search, automatic indexing, Matrix extraction, Evidence Scan) at $8.99/month, $49.99/year or $99.99 lifetime, with verified student pricing at $4.99/month or $29.99/year.

- **Reading Studio:** A side-by-side dual-pane reader that puts the PDF and your markdown editor next to each other, so highlights and annotations become part of your notes as you read.
- **Citations anchored to passages:** Generate BibTeX or APA citations from PDF metadata, with every citation linked back to the exact highlight it came from so you can return to the passage months later.
- **Local semantic search:** A premium feature that searches your library by meaning rather than exact keywords, powered by on-device models so nothing is uploaded.
- **Knowledge graph and Neo4j export:** Bidirectional links between notes and sources build a visual relationship graph that can be exported in a Neo4j-friendly format.
- **Evidence Scan and Matrix extraction:** Local AI treats a sentence as a claim and surfaces supporting, contradicting and nuanced passages; Matrix extraction fills editable research tables straight from your own library.

**Strengths:** Genuinely local AI: indexing, retrieval and inference run on your Mac rather than in the cloud; Plain markdown and PDFs on disk, so your data stays portable and readable in any editor; Citations, highlights, notes and sources live in one window instead of four tethered apps; Transparent technical write-ups documenting chunking, ranking and known failure modes

**Limitations:** macOS only, so Windows and Linux researchers are excluded; A younger app than Zotero or Obsidian and lacks their two decades of templates and plugins; No Word or Google Docs integration, and the local AI workflows sit behind the Premium tier

## 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
