eightytwenty

eightytwenty helps you plan and build slide decks for case competitions, pitches, class projects and finance pitches. It gives Claude a step-by-step playbook from experienced case competitors: the questions to ask before writing, a text plan you approve, the build, and a QA pass that includes a writing check so slides read like a person wrote them. While planning, Claude can search a library of more than 900 slide layouts and 39 whole-deck flows, drawn from strong case-competition and investment-banking decks. Every reference is an abstract wireframe with its layout, why it works and when to use it, so Claude rebuilds the idea in your own style instead of copying anyone's slide. Filters cover slide type (executive summary, market, financials, valuation, LBO returns and more), industry and deck style. Claude can also find a logo, icon or photo for a slide: public-domain logos, permissive icon sets and openly licensed photos, with a credit line only when the licence needs one. It is read-only and needs no account. It never sees your files or chat, only the search terms Claude sends.
