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
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.
A converter, not a prompt box
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 on the canvas.

How it works
Bring the notes, outline, or Markdown you already wrote. Headings are optional but make the structure explicit.
Use # / ## headings for sections and - / * / 1. markers for bullets. Plain paragraphs still produce bounded slides.
Review the slides and any warnings, then export to PPTX or PDF when the structure looks right.
Source rules
Hash headings create slide boundaries, list markers become bullets, and unmarked prose is split by blank-line paragraph groups.
A # or ## heading creates a readable section boundary. A second-level heading starts a slide when the current slide already has content.
Bullet and numbered markers become slide bullets instead of remaining as ambiguous plain text.
Long sections continue onto a titled continuation slide instead of being squeezed into one dense page.
Output behavior
Supported formats & specifications
Benchmark pending for this input; limits are not guessed on this page.
| Aspect | Current behavior |
|---|---|
| Input | pasted text or Markdown |
| Result | Full editable 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
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.
Current public contract
| Aspect | Current behavior | Why it matters |
|---|---|---|
| Input | pasted text or Markdown | The named source front-end determines which structural signals are read. |
| Review | Every slide is editable on the canvas before export. | You can inspect and correct the output before anything leaves the workspace. |
| Free preview | Full editable 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. | Slides are rebuilt as real objects rather than flattened page images. |
| Method | Structural extraction and slide assembly, not paraphrase. | The same source structure produces the same conversion behavior. |
Yes. Paste plain prose into the converter. Blank-line-separated paragraph groups become bounded slide content; headings and bullets give you more control.
No. Markdown markers are supported, not required. The converter also accepts ordinary text and uses paragraph groups when there are no headings.
No. This path preserves the supplied wording and structure. AI restructuring is a separate, opt-in step you choose afterwards.
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.

Reviewing is the point: you can see whether the source structure made a useful deck, and fix it on the canvas, before anything is exported.
