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 turns any supported document into clean, structured Markdown that ChatGPT and Claude read correctly.

Why prepare documents first
- AI reads clean Markdown structure far more reliably than raw extracted text.
- Repeated page headers, footers, and page numbers are stripped out.
- Tables and lists are rebuilt instead of collapsing into a wall of text.
- Every word of your content is kept — nothing is summarized or invented.
Questions
Which documents can I prepare?
PDF, Word (.docx), PowerPoint (.pptx), Excel (.xlsx), HTML, CSV/TSV, and plain text — up to 20 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.
