## 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

## Perplexity

Perplexity is an AI-native answer engine and autonomous research platform designed to replace traditional keyword search and fragmented browser tab workflows. Instead of returning a ranked list of blue links, Perplexity interprets complex natural-language queries, crawls live web indexes, academic databases, financial filings, and social discussions in real time, and synthesizes direct, structured answers anchored by numbered inline citations. Beyond conversational search, the platform has evolved into a broader agentic ecosystem encompassing Perplexity Computer for autonomous multi-step tasks and the Comet AI browser assistant.

Under the hood, Perplexity orchestrates its proprietary web-grounded Sonar model family alongside frontier third-party reasoning models—allowing paid subscribers to route queries through Claude Opus 4 and Sonnet 4, OpenAI's o3-pro and GPT series, or Google's Gemini models, or run parallel evaluations via Model Council. Its Deep Research mode autonomously decomposes intricate questions, conducts dozens of iterative searches across hundreds of primary sources, and compiles exhaustive, exportable briefing reports in minutes. Users can also organize ongoing projects inside Perplexity Spaces, which fuse uploaded private documents (PDFs, CSVs, docs) with live web grounding and custom system instructions.

Perplexity serves an expansive audience ranging from students and journalists to equity analysts, legal researchers, and software engineers. Individual users can rely on the free tier for everyday fact-checking, step up to Perplexity Pro ($20/month) for daily deep research and model switching, or subscribe to Perplexity Max ($200/month) for uncapped high-compute agentic runs. Organizations adopt Enterprise Pro ($40/seat/month) and Enterprise Max ($325/seat/month) for SOC 2 compliance, zero data training guarantees, and internal knowledge connectors, while developers integrate real-time grounded citations into custom software via the Sonar REST API.

**Pricing & Plans:** Offers a permanent Free tier with unlimited Quick Searches, 3 Pro Searches per day, and 1 Deep Research query per month; Perplexity Pro costs $20/month ($200/year) and Perplexity Max costs $200/month ($2,000/year) for individuals. Team plans start at $40/seat/month ($400/seat/year) for Enterprise Pro and $325/seat/month for Enterprise Max, alongside usage-based Sonar API billing.

- **Deep Research Autonomous Reports:** Executes multi-step iterative web and document research across hundreds of sources, cross-checking facts and generating structured, citation-backed analytical reports that can be exported as PDFs or shared as interactive Perplexity Pages.
- **Multi-Model Routing & Model Council:** Lets Pro and Max subscribers switch dynamically between Perplexity's in-house Sonar models and top external models (including Claude 4, o3-pro, and Gemini) or compare multi-model reasoning outputs side by side.
- **Perplexity Spaces & Hybrid RAG:** Provides dedicated project workspaces where users upload local PDFs, spreadsheets, and text files, configure custom assistant instructions, and run queries that combine private document retrieval with live internet search.
- **Perplexity Computer & Comet Assistant:** Extends Perplexity from passive Q&A into agentic execution, turning high-level user requests into completed workflows, multi-tab browser actions, and automated data synthesis via the Comet ecosystem.
- **Sonar Web-Grounded Developer API:** Exposes Sonar, Sonar Pro, Sonar Reasoning Pro, and Sonar Deep Research over standard HTTP endpoints so developers can embed low-latency, live-cited web intelligence directly into third-party applications.

**Strengths:** Every generated statement links directly to numbered, verifiable web or document sources, drastically reducing ungrounded LLM hallucinations.; Deep Research mode delivers comprehensive, multi-page synthesis reports at a fraction of the time required for manual desk research.; Broad model optionality lets subscribers use Sonar, Claude, OpenAI, and Gemini models under a single $20/month subscription.; Focused search scopes (Academic, Finance, Web, Social) and Spaces allow clean separation between general browsing and domain-specific knowledge work.

**Limitations:** The Free tier is tightly restricted to 3 Pro Searches per day and just 1 Deep Research query per month with no manual model selection.; Power users requiring heavy agentic Computer runs or uncapped o3-pro/Opus-level research must jump from $20/month Pro to the steep $200/month Max tier.; Synthesized summaries can still inherit inaccuracies if underlying top-ranked web sources contain outdated or biased reporting.
