How to choose (My Decision Heuristics)

Image create with Microsoft Copilot.

• If you live in Google Workspace: Start with Gemini AI Pro; upgrade to Ultra only if you really need Veo 3 or Deep Research at scale.
• If you want one tool that “just works”: ChatGPT Plus (or Pro if heavy usage + Sora needs).
• If you write long reports or refactor big codebases: Claude Pro/Max for extended thinking and big context.
• Design‑first visuals: Midjourney; for compliance‑friendly images inside one stack, DALL·E 3.
• Video pipelines: Runway (clear pricing, editor) or Veo 3 (highest fidelity + audio) if you can justify AI Ultra/API costs.
• Build MVPs fast: Lovable for full‑stack, v0 for high‑quality UI.
• Music: Suno for catchy vocals; Udio for detailed editing/stems.
• Evidence: Consensus (papers), Perplexity (live web + sources), SciSpace (agentic workflows).

ROI Quick Calculator (back‑of‑the‑envelope)

Formulas
– Monthly value of time saved = hourly_rate × hours_saved_per_week × 4.33
– Net ROI = (value_saved − tool_cost) ÷ tool_cost
– Break‑even hours/week = tool_cost ÷ (hourly_rate × 4.33)
– Cost per hour saved = tool_cost ÷ (hours_saved_per_week × 4.33)

Example A (ChatGPT Plus): hourly rate $50, saving 2 h/week, cost $20 → value = 50×2×4.33 = $433; net ROI = (433−20)/20 = 20.7×.

Example B (Runway Pro): hourly rate $40, saving 3 h/week, cost $28 → value = 40×3×4.33 = $519.6; net ROI = (519.6−28)/28 = 17.6×.

Tip: If net ROI ≥ 3× and outputs meet quality bars, standardize the tool in your workflow; otherwise, keep it ad‑hoc.

Final take: The right AI stack isn’t a trophy shelf, it’s a workflow. Start with one chat assistant and one specialist per need (image, video, code, music, research), measure outcomes (time saved, output quality, cost), then expand deliberately. If you’re weighing trade‑offs for your specific use case, drop a note in the comments—ask anything. Share your goal, constraints, and budget, and I’ll suggest a lean setup you can ship with today.
