Paste the source
Bring the notes, outline, or Markdown you already wrote. Headings are optional but make the structure explicit.
Gixo Lumen · deterministic document conversion
Turn pasted text into a PowerPoint slide outline you can inspect before you download it.
Paste text or Markdown, use headings to mark slide boundaries, and see the resulting deck immediately. Bullets remain bullets; plain paragraphs are grouped into readable sections. Nothing is invented to fill a gap in the source.
Editable slides, not screenshots
Free preview, no account required
Structure read from your source
Your wording kept
PPTX and PDF export
Stable layouts export as editable PowerPoint text and shapes; complex slides export as images that keep their appearance, so their text cannot be edited separately.

Real slide text, tables, and extracted structure
Pasted text, Markdown headings, bullet lists, numbered lists, or blank-line-separated prose.

Input
Use # / ## headings for boundaries and - / * / 1. markers for bullets. A 60-slide cap applies.A converter, not a prompt box
Turn the structure you already have into a slide preview.
The best input is a text outline with headings and bullets. If you need the converter to infer a story from scattered notes, that is a generation job rather than a deterministic conversion job.
The conversion step is deliberately structural. It extracts the source, identifies headings and blocks, and splits long sections into readable slides — it does not paraphrase your source or invent a narrative around it. Rewriting, restructuring and theming are separate, opt-in steps you take afterwards in Lumen.

How it works
Three bounded steps from text or Markdown to slides.
Use simple markers
Use # / ## headings for sections and - / * / 1. markers for bullets. Plain paragraphs still produce bounded slides.
Review the deck
Review the slides and any warnings, then export to PPTX or PDF when the structure looks right.
Source rules
What the converter reads from text or Markdown.
Hash headings create slide boundaries, list markers become bullets, and unmarked prose is split by blank-line paragraph groups.
Headings
A # or ## heading creates a readable section boundary. A second-level heading starts a slide when the current slide already has content.
Lists
Bullet and numbered markers become slide bullets instead of remaining as ambiguous plain text.
Overflow
Long sections continue onto a titled continuation slide instead of being squeezed into one dense page.
Output behavior
What stays faithful, and what does not.
Preserved or represented
- Top-level and second-level Markdown headings
- Bullets and numbered lists
- Paragraph groups separated by blank lines
- Source wording without model-generated additions
Outside this batch
- AI-generated titles or summaries
- Rich Word or PDF layout
- Images or diagrams that were not present in the pasted source
Supported formats & specifications
The contract we can state today.
Benchmark pending for this input; limits are not guessed on this page.
| Aspect | What to expect |
|---|---|
| Input | pasted text or Markdown |
| Result | Full deck preview in the browser, including slide count, source-page count, and extraction warnings. |
| Free vs signed in | Preview is free without an account. Sign in to download PPTX or PDF, apply a brand kit or theme, or restructure the narrative with AI. |
| Measured limits | Benchmark pending for this input; limits are not guessed on this page. |
| Extraction | Structural, not generative: headings, blocks and tables are read from the source rather than rewritten. |
| Safety | Uploads are validated and bounded-parsed. URL conversion accepts public HTTP/HTTPS pages only. |
What conversion does, and what it leaves to you
Structure is extracted. Judgement stays yours.
Conversion reads the structure already in your source and lays it out as slides. The complete preview is free without an account; downloading, brand kits, theming, and AI restructuring begin after sign-in. Nothing is silently reworded between the file you brought and the deck you present.
A note about text structure: A clear outline gives the deterministic parser more useful boundaries; it will not invent missing titles, examples, or conclusions.
Details
What text or Markdown to PowerPoint conversion includes
See what the free converter does, what remains unchanged, and where the full Lumen workflow begins.| Topic | Details | What to know |
|---|---|---|
| Input | pasted text or Markdown | The source format determines which structural signals the converter reads. |
| Review | Every slide appears in the browser preview before export. | You can inspect the output before anything leaves the workspace, then edit the downloaded PPTX in PowerPoint. |
| Free preview | Full deck preview without an account. | Slide count, source-page count, and extraction warnings are visible before sign-in. |
| Export | PPTX and PDF after sign-in, with editable text and native tables on stable layouts. | Stable layouts export as editable PowerPoint text and shapes; complex slides export as images that keep their appearance, so their text cannot be edited separately. |
| Method | Structural extraction and slide assembly, not paraphrase. | The same source structure produces the same conversion behavior. |
Can I convert plain text to PowerPoint?
Yes. Paste plain prose into the converter. Blank-line-separated paragraph groups become bounded slide content; headings and bullets give you more control.
Do I need Markdown?
No. Markdown markers are supported, not required. The converter also accepts ordinary text and uses paragraph groups when there are no headings.
Will the text be summarized?
No. This path preserves the supplied wording and structure. AI restructuring is a separate, opt-in step you choose afterwards.
How many slides can the converter make?
The pipeline has a hard cap of 60 slides and warns when it truncates beyond that cap. File-size and timing figures are intentionally left off until benchmarked.

Ready to inspect the result?
Convert text or Markdown to PowerPoint and review the slides before you export.
Reviewing is the point: you can see whether the source structure made a useful deck before anything is exported, then edit the downloaded file in PowerPoint.
