I turned my open-source paper-reading CLI into a desktop app — and gave it an honesty rule

说明与用途

PaperLens Pro 将 CLI 论文阅读工具转变为桌面应用，支持批量处理、预览和导出，并执行诚实规则，若信息缺失则标记为"不清楚"。

问题

Users needed a more efficient way to read and summarize multiple research papers without generating fabricated information.

结果

PaperLens Pro enables efficient, honest summarization of multiple research papers with batch processing, preview, and export features, while preventing fabricated content through an explicit "unclear" rule.

工作流

• Install the source package and run the double‑click launcher.
• Add PDFs via drag‑and‑drop, folder selection, or individual files to the queue.
• The app extracts text (pypdf), truncates to 12,000 characters if needed, and sends it to the chosen LLM backend with a strict prompt.
• The LLM returns a Markdown report with five sections: TL;DR, key contributions, method, key results, reproduction notes.
• The app displays the report in‑app and allows one‑click export to a single .md per paper or a combined file for Obsidian, Notion, or a lab wiki.
• If the PDF has no extractable text, the app informs the user that OCR is required.
• The user can configure API keys for Ollama, Groq, or any OpenAI‑compatible endpoint in a local settings file.
• The app respects the honesty rule: if the paper text does not cover a requested detail, the report contains "unclear" instead of fabricated content.
• The user can tweak the prompt or build a standalone executable with PyInstaller if desired.

Every week, my "to read" folder gained ten PDFs and lost none. The classic fixes didn’t work for me: pasting papers into a chat window one at a time is slow, and the summaries I got back had a worse problem — they sounded confident about things the paper never said.

The CLI worked. But it only worked for people comfortable in a terminal, one paper at a time, with no way to see a queue, preview a report, or export a whole batch into notes.

The one design decision I care most about is in the prompt. It instructs the model: if the paper’s text doesn’t cover something, write "unclear" — do not fill the gap with something plausible.

PaperLens Pro is delivered as a source package with double-click launchers, not a signed installer.
