Decks that make an argument.

The storyline is settled before a slide is opened, every title is a claim, the charts come out of your own model, and the deck is inspected before you see it.

01What it does

It settles the argument before it opens a slide.

A deck fails in the outline, not the layout. So the storyline comes first, and every slide after it is built, compared and inspected.

01Storyline first

The argument first. Then the slides.

It locks what the room has to believe, gives every beat an action title, and only then composes. The structure is visible before anything is laid out.

  • Audience, length and outcome settled up front
  • One action title per beat
  • The structure is visible before anything is composed

02It compares options

For the slides that carry the most weight, it builds genuinely different versions and looks at both before keeping one. Comparing beats iterating when the space is wide.

The runner-up’s better ideas are kept

03One visual system

Palette, type and spacing committed to once, from your brand kit or an image you like.

The same system on all fourteen slides

04Charts from the model

Figures come out of your workbook. Diagrams stay editable.

The deck and the model cannot disagree

05It looks at its work

Overlaps, clipped text and contrast failures are found in the rendered pixels.

A whole-deck audit at the end

06What you actually say

Notes carry the point of each slide, the number worth repeating, and the way to the next one.

02LumenAgent in LumenSlides

It builds the deck, and stops to ask.

It reads your library, locks the storyline, compares two covers with its own eyes, and waits for you before it clears a slide you made. Decline and it builds around them.

Clear the six slides that are already here?

The storyline replaces them end to end. Keeping them means the new deck is appended after the old one instead.

03The full toolkit

Everything LumenSlides does, and all of it free.

No slide limits, no watermark, no upsell halfway through a deck.

Storyline

The part that decides whether it lands.

  • A claim per slide, not a label
  • The argument ordered before any layout
  • Held to the length you asked for
  • Templates for a structure that fits

Design

One system, obeyed throughout.

  • Themes from your brand kit or an image
  • Backgrounds and covers made for this deck
  • Brand templates across every slide
  • Type and palette committed to once

Compose

Real slides, real content.

  • Layouts composed, not poured into placeholders
  • Charts and tables from your workbook
  • Diagrams that stay editable
  • Images, icons and graphics: yours, stock, or generated on Pro and above

Judge

Options beat iterations, on Lumen Expert and Ultra.

  • Genuinely different versions of pivotal slides
  • Judged side by side on rendered pixels
  • Smart blocks: real composed options
  • The best kept, runner-up ideas included

Polish

It looks at what it made.

  • Overlaps and clipping found by rendering
  • Contrast checked, not assumed
  • Hierarchy and spacing fixed after seeing it
  • A whole-deck audit at the end

Present & hand on

Out of the editor.

  • Speaker notes and transitions
  • Presenter view with timing
  • .pptx and .pdf export
  • An appendix workbook or a written version

04Works with the rest

A deck is the last step, not the only one.

The deck, the memo and the model all carry the same numbers.

  1. Reads

    The revenue model

    Chart figures come out of the workbook rather than being retyped from a screenshot.

  2. Reads

    Last quarter’s board pack

    A 60-page PDF, read for the metrics and the commitments already made.

  3. Built here

    Fourteen slides

    Storyline, theme, composed slides, rendered checks and speaker notes.

  4. Hands off

    The appendix workbook

    Backup figures built by LumenSheets, so the room can be shown the working.

05Questions

Common questions

Does it just fill in a template?

No. It settles the storyline, generates a theme from your brand kit and composes each layout for its content. Templates are a starting structure only.

Where do the chart numbers come from?

Your own workbook, read directly rather than from a screenshot or a figure in the prompt, so the deck and the model cannot disagree.

Will it delete the slides I already made?

Not without asking. Clearing a deck pauses for approval, and declining builds the new slides after yours.

Can I export to PowerPoint?

Yes. .pptx and .pdf, with the speaker notes attached.

What does it mean that it “looks at” the slides?

The deeper engines render each slide and inspect the pixels, so overlaps, clipped text and contrast failures are caught, not reasoned about.

Walk in with the argument made.
