Prepare any document for AI

PDFs, Word files, slide decks and spreadsheets often break when you paste them straight into AI — columns interleave, tables collapse, and the AI answers from garbled text. LessTokens rebuilds any supported document as clean, structured Markdown you can review, then take to the AI tool you already use.

Beary is waiting for a document. Choose or drop a file to begin.

Documents and screenshots use this same picker: PDF, Word, OpenDocument, PowerPoint, Excel, HTML, CSV/TSV, TXT, Markdown, JSON, XML, YAML, LOG, PNG or JPG · up to 100 MB

You can also paste a copied screenshot anywhere on this page with Ctrl/⌘+V.

Prepare once, then take it to the AI you choose

LessTokens prepares the document. You review what came through. Then you copy or download the Markdown and bring it to your own AI tool.

  1. 1. Prepare

    Upload a supported document. LessTokens rebuilds it as clean, structured Markdown.

  2. 2. Review

    Check the result and any warnings before you rely on it. Warnings stay attached to the copied and downloaded file.

  3. 3. Copy or download, then bring it to your AI

    You choose the destination, and you perform the final paste or upload yourself.

Markdown is plain text. You can copy it, or download it as a .md file. Whether a given destination accepts pasted text or a .md upload depends on what that tool currently supports.

Intended for AI tools that accept pasted text or Markdown files. Which tools those are, and how each one handles a particular document, is something LessTokens cannot verify for you.

Nothing is sent automatically. LessTokens does not transmit your document to an AI provider — the last step is always yours.

You might take the result to ChatGPT, Claude, Gemini, NotebookLM or Codex — examples of destinations you could choose, not measured or recommended ones. Those names are examples only. LessTokens is an independent tool, is not affiliated with, endorsed by or sponsored by their owners, and has not verified how any of them accepts or handles a converted file. What each one supports can change over time.

Why prepare documents first

  • Clean Markdown structure carries headings, tables and lists that raw extracted text loses.
  • Repeated page headers, footers, and page numbers are stripped out.
  • Tables and lists are rebuilt instead of collapsing into a wall of text.
  • Nothing is summarized or invented — but parts of a document may not convert cleanly, and anything we could not read is disclosed for you to check.
  • Whatever we could not read cleanly is disclosed, so you know what to check before relying on it.

Questions

Which documents can I prepare?

PDF, Word (.docx), OpenDocument Text (.odt), PowerPoint (.pptx), Excel (.xlsx), HTML, CSV/TSV, TXT (.txt), Markdown (.md), JSON, XML, YAML (.yaml/.yml), and LOG files — up to 100 MB per file.

Is my file private?

Files are processed temporarily, never used to train AI, and automatically deleted within 60 minutes. See the privacy policy for the full detail.

File retention

Uploaded originals and conversion results are temporary. They are not kept as a permanent document library.

  • Uploaded originals are used only to produce your Markdown result and are deleted as soon as processing ends, or within 60 minutes at the latest.
  • Conversion results and job records are available for up to 60 minutes, then expire and are automatically removed from the active database.
  • We do not keep a permanent document library. Limited provider-managed infrastructure snapshots may retain residual copies for up to 5 days before automatic expiry.
  • Uploaded originals are held in temporary local storage only while the job is processed. Recurring cleanup removes any expired temporary upload left by an interruption.
