AI Workflow Stack
AI Research Stack
Find, verify, summarize, and organize research faster
Minimal viable start
Overwhelmed by the full stack? Start with just Perplexity AI — it covers the most critical layer of this workflow.

Workflow map
How each core tool fits into the workflow — in order.
Cited web research and fast answer discovery.
Reasoning, synthesis, outlines, and draft generation.
Long-document reading, summarization, and careful rewriting.
Organize notes, sources, and research projects.
Budget paths
Start small. Expand only when the core workflow is running consistently.
Free / starter path
Good for testing the workflow. Upgrade when limits become a real bottleneck.
Full stack
Est. total: Free – $60/mo. Verify current pricing before committing.
Watch for overlap
Perplexity AI appears in both the starter and full stack. Do not pay for tools that solve the same layer as something you already have. Expand only when a real bottleneck appears.
What to buy first
- → Perplexity AI — Cited web research and fast answer discovery
- → ChatGPT — Reasoning, synthesis, outlines, and draft generation
- → Claude — Long-document reading, summarization, and careful rewriting
What to skip early
- – Gemini — Google ecosystem research and multimodal assistance.
Why this stack exists
An AI research stack for students, analysts, writers, and operators who need cited research, summaries, document analysis, and structured notes.
How to use this stack
Start with perplexity as the minimum viable tool. Add the remaining tools only when the workflow becomes frequent enough to justify more moving parts.
What to skip
Do not buy every tool at once. Start with the main workflow, test it for a few real projects, then add the supporting tools when they clearly save time or improve output quality.
Stack verdict
Start with the smallest stack that covers your current workflow. Add specialist tools only when a real bottleneck appears — not before.
