The four tools, in plain English

ChatGPT (Web)

Great for longer, structured outputs, multi-section drafts, and polished reasoning.

Google Gemini (Web)

Excel-minded assistant: loves structure, checklists, visuals, and interpreting screenshots.

Microsoft Copilot (Web)

Business tone governor: de-fluffs text, standardizes bullets, and makes language stakeholder-safe.

Perplexity (Web)

Fast research with citations: scan, compare, and support claims with sources.

Use any one tool—or mix and match.

Crash Course: start now

1. Open ChatGPT, Gemini, Copilot, or Perplexity

2. Type a real task you have today (meeting agenda, reply to email, status bullets).

3. Paste context. Ask for a brief, bullets, table, or checklist.

4. Verify with evidence lines or citations.

5. Tighten tone to neutral, professional, and policy-safe.

You’ll feel the time savings immediately.

Settings that matter (web-only)

Custom Instructions (CI)

Tell the model what you value: accuracy, tone, brand rules, formats, date/time zone.

Memory

Save stable facts (team, projects, preferences) to reduce re-explaining.

Privacy & data controls

Turn off training where available. Redact sensitive data. Use placeholders for names, IDs, and amounts.

Model/version pickers

“Instant” for quick tasks. “Thinking” for multi-step reasoning or research.

Prompting Playbook (you’ll use this daily)

RCIES — Role, Context, Inputs, Examples, Success Criteria

Give the model a role, tell it what matters, paste inputs, show examples, and define success.

TCR — Task, Context, Rules

State the task, supply context, and set hard rules (word caps, tables, tone, evidence).

Iteration loop — Draft → Critique → Revise

Ask for a first draft, critique against your rubric, and iterate to final.

Chain-of-Tasks

Split complex work into steps; avoid “do everything in one go”.

Verification Patterns

• Citations or evidence lines after bullets.

• Counter-prompts (strongest objections + tests).

• Assumptions to verify (what, where, how).

File handling (corporate-ready)

PDFs

Extract page-referenced bullets, quotes ≤10 words, and page numbers.

Excel/CSV

Summarize trends without new math. Use present cells only. Keep no-new-numbers rule.

Slides/Docs

Convert to briefs, bullets, tables, and checklists. Ask for an outline by slide.

Everything audit-friendly.

Role-based workflows (copy/paste ready)

Sales & Customer Success

• Discovery → recap + next steps.

• Objection matrices with proof and tests.

Output shapes that drive action

• Tables with explicit columns (Owner, Action, Due, Evidence, Status).

• Checklists with owners and dates.

• One clear ask with a by-when.

Stakeholders won’t just read—they’ll act.

Governance and guardrails

• Policy first: follow your company’s confidentiality, data, and retention policies.

• Evidence: include source links, quotes, or page numbers.

• No-new-numbers: never invent figures; use only what’s provided.

• Assumptions: declare them and specify where/how to verify.

• Policy-safe rewrites: remove over-promises; use stakeholder-safe tone.

This is how you make AI corporate-ready.

Speed boosters you’ll reuse

• Tone presets (formal, neutral, friendly-professional).

• Word caps (briefs, emails, bullets).

• Tables on demand (name the columns up front).

• Date/time localization (DD-MMM-YYYY, your time zone).

Small rules. Huge speedups.
