📰 PDF Q&A Best Practice

  • OCR quality check (scanned PDF ঝামেলা)
  • Page reference demand করুন
  • "Quote the exact sentence" verify করুন
  • Cross-check hallucination possibility
  • লম্বা PDF → chunk-wise summarize → combined analysis

⚠️ Research Pitfall

  • AI citation hallucinate করতে পারে — always click-verify
  • Paywalled paper access-এ সীমাবদ্ধতা
  • Date bias (recent over-weighted)
  • Western source dominant
  • Translation loss

💡 Advanced Technique ⭐

  • Multi-tool pipeline: Perplexity → Claude (analyze) → Gamma (slide)
  • Iterative refinement: broad → narrow → deep
  • Counter-research: "Find strongest argument against my thesis"
  • Expert persona: "Analyze as a domain expert in X"
  • Time-boxed: "Only sources from last 6 months"

🗂️ Research Organize

  • Notion / Obsidian-এ knowledge base
  • Zotero / Mendeley reference management
  • Readwise — highlight sync
  • Every research output markdown-এ save
  • Tagged, searchable
