## Isaac

Isaac is built around the idea that academic writing is not one task but a chain of them: finding sources, reading closely, taking notes, drafting, revising, and citing. Rather than stitching together a reference manager, a chat assistant, and a word processor, Isaac folds these into a single desktop workspace so the material you gathered stays within reach while you write.

At its center is an academic-tuned AI assistant. It can autocomplete sentences, paraphrase passages, summarize documents, and help produce a first draft, all while you keep control of the final text. A literature search feature lets you find relevant papers inside the app, and a reference management panel keeps them organized. You can also upload papers directly and ask questions about their contents, which shortens the loop between reading and writing.

The service is used by tens of thousands of researchers and is available in 16 languages, with data hosted on GDPR-compliant EU servers. Pricing runs from a free-forever tier with modest daily AI tokens up to paid plans with higher token allowances, file uploads in chat, and premium models.

**Pricing & Plans:** Freemium. Free: $0 forever, no credit card, 10 daily AI tokens and 100 MB file storage. Basic: about $8/mo billed annually, 50 daily AI tokens, 1 GB storage, file uploads in chat, and first-draft generation. Pro: about $16.66/mo billed annually (around $25 monthly), unlimited AI and chat, unlimited file storage, premium AI models, and priority support.

- **Academic AI assistant:** A ChatGPT-style assistant tuned for scholarly writing, with autocomplete, paraphrasing, summarization, and first-draft generation.
- **Literature search and references:** Search relevant academic literature inside the app, then keep sources organized in a reference list beside the editor.
- **Chat with documents:** Upload your papers and ask questions about them, so you can interrogate a source without leaving your document.
- **Workflow automation:** Automated functions help streamline literature reviews and other repetitive research tasks.
- **Unified writing workspace:** A distraction-free editor that keeps writing, sources, and AI support in a single desktop window.

**Strengths:** Brings literature search, referencing, and AI writing into one workspace; Free-forever tier for students who want to try it; Available in 16 languages; Data hosted on GDPR-compliant EU servers

**Limitations:** Desktop only — no mobile app yet; Free tier is limited to 10 daily AI tokens; No guarantee of originality; you still need to review cited output; Some workflow features are marked as coming soon

## 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
