Perplexity AI

FREEMIUM

Overview Perplexity is not just a chatbot—it is an AI-powered "Answer Engine" that replaces traditional search. Instead of giving you ten blue links to click through, Perplexity reads the internet for you and delivers a concise, accurate answer with footnotes and citations for every claim. Why Use Perplexity? If you need factually accurate information fast, Perplexity is the gold standard. It combines the power of multiple leading AI models (like GPT-4o, Claude 3.5, and its own Sonar models) with real-time web indexing. It is essentially a research assistant that never sleeps. Key Capabilities: Deep Research: A powerful mode that autonomously performs dozens of searches, reads hundreds of sources, and generates comprehensive reports or articles on complex topics. Trustworthy Citations: Every sentence generated is linked to a real source (news sites, academic papers, blogs), allowing you to verify facts instantly—solving the "hallucination" problem of other AIs. Model Switching: Pro users can toggle between different "brains" for their search, choosing between GPT-4o, Claude 3.5 Sonnet, or Perplexity's own Sonar Reasoning (based on Llama 3/DeepSeek). AI Shopping: A new 2025 feature that acts as a personal shopper, finding the best products, comparing prices, and even allowing one-click checkout via PayPal integration.

Obsidian Canvas

FREE

Overview Obsidian Canvas is the ultimate "Space for Thinking." Unlike online whiteboards (like Miro) that lock your data in the cloud, Obsidian Canvas is local-first. It creates an infinite spatial interface where you can drag and drop your existing Markdown notes, PDFs, images, and websites to visualize complex connections. It is the missing link between linear note-taking and visual brainstorming. Why Use Obsidian Canvas? If you are building a "Second Brain," Canvas is essential. It allows you to visualize your knowledge graph without writing a single line of code. Because it stores data as open JSON/Markdown files on your hard drive, it is future-proof and private. It is widely used by AI researchers to map out prompt chains, structure large writing projects, and organize complex research data that needs to be cited and linked. Key Capabilities: Markdown Native: Every "card" on the canvas can be a fully functional Markdown note. You can edit the text directly on the canvas, and it updates the file in your vault instantly. Embed Everything: It’s not just for text. You can embed live websites, YouTube videos, PDFs, and audio files directly onto the board, creating a multimedia dashboard for any project. Infinite Spatial Canvas: There are no borders. You can zoom out to see the "Big Picture" of a novel’s plot or zoom in to write the specific details of a single chapter. Privacy & Longevity: Unlike SaaS tools that can shut down or sell your data, Obsidian Canvas files sit locally on your device. You own 100% of your data, making it the safest place for sensitive intellectual property.
