Hi, I am Eldad, the maker of TrimDown. I kept hitting the end of the context window. The cause: large PDFs cost far more tokens than the same words in Markdown. So I started to convert my PDFs first. I wrote my long prompts in Word, to review them. Then I needed the AI's answer back as a client-ready Word document in my own template. I found nothing on the Mac that did that round trip. So I made it. What it does: - Imports Word, PDF, PowerPoint, Excel, HTML, EPUB, CSV, TXT, JSON, XML, a web page by address, or a scanned picture (on-device OCR) as clean Markdown. - Turns the model's Markdown answer into a real .docx in your Word template: fonts, heading styles, header, footer. Pictures and Mermaid diagrams go in as real pictures. PDF export too. - Live preview, find and replace, right-to-left text. Token counts (Anthropic token counting API, Claude Opus 5): - My own 3,000-word spec with 22 screenshots: 45,458 tokens as a PDF, 6,788 as Markdown. That is 85% fewer. - A real 27-page analyst report: 66% fewer. - A dense, almost all-text annual report: 17% fewer. That is the floor. Mac only (macOS 13 or later). Free download, free 30-day trial, then one purchase of US$ 29.99. Launch price: US$ 24.99 until 30 November. No subscription, no account, no cloud. Tell me which document you try first, and where the result is not good enough. I will answer every comment.

Why I started TrimDown in a crowded Markdown editor market

When working with Claude, Gemini and ChatGPT, I kept running into delays with the end of the context windows. I realized that I need to turn my input files - PDF, Word and URLs, into Markdown to substantially reduce the input without compromising the content. I also needed some of the output in Word in my own template, and no engine could do that.
I tried some simple Markdown editors - they were too simple for AI work and lacked features I needed, such as importing any format, a full synched preview, more editing tools. I tried the leading Markdown editors - they were too complex. And no one could output the AI results in my own Word template.
This led me to create TrimDown.
I would love to get your feedback and update it to fit your needs.
