Whyston

Whyston generates consulting-grade presentations directly in PowerPoint. Describe your presentation in a sentence — or answer a few quick questions — and Whyston builds a complete, structured deck and inserts the slides straight into PowerPoint.

What you get

• AI deck generation — a structured SCQA narrative, MECE pillars, and action-title slides.
• Native PowerPoint charts — bar, line, pie, and waterfall, fully editable in PowerPoint.
• Chart overlays — brackets, delta braces, callouts, CAGR and trend arrows, reference lines.
• AI image generation — on-brand editorial, vector, or photographic visuals.
• Evidence upload — attach a PDF, DOCX, or PPTX and Whyston extracts it into a structured brief.

Works on PowerPoint for Windows, Mac, and the web. Sign in with email, Google, or Microsoft SSO.

Account and pricing

Whyston requires a Whyston account. A free tier is available; continued or higher-volume use requires a paid Whyston subscription. See whyston.com for current plans and pricing.
