About DeckEdit

DeckEdit was co-founded by Keith Li and Roy Law, CEO and co-founder of TeamNote, a Y Combinator-backed company. Keith is the Chief Agentic Engineer. He built the entire app using AI agents under his direct supervision. DeckEdit is now two free, fully local tools with one promise. Your files stay on your device. No hidden costs, no data collection, no compromises. See what's new

Two products, one promise

The problem

AI tools like NotebookLM produce beautiful slides, but they are exported as flat images. You cannot select the text, fix a typo, or restyle a heading. Most online deck editors solve that by uploading your file to a server, which is a privacy problem of its own.

The solution

DeckEdit covers both sides of that gap, locally. The NotebookLM Slide Converter rebuilds every slide as a real editable .pptx. The Free Online Presentation Editor lets you open any PDF or image deck and edit the text directly in the browser. The original layout and graphics are preserved. Nothing is sent to a server.

How it works

1. 1

   Upload

   Drop a PDF or image deck into DeckEdit. On-device detection finds every text region.

2. 2

   Edit or convert

   Edit text directly in the browser, or convert the deck to an editable .pptx with one click.

3. 3

   Download

   Save the result as .pptx, PDF, or image. Nothing leaves your device at any step.

Why DeckEdit

• 100% Local Processing: Your files never leave your device. All OCR and editing happens in your browser. No server uploads, no cloud storage, no privacy concerns.

• No Registration Required: Start using DeckEdit immediately. No email, no account, no trial period. Just drop your file and go.

• True Editable Text: Unlike screenshot-to-PDF tools, DeckEdit creates real text boxes you can click, edit, and format. Not background images with text overlays.

Who It's For

• Professionals who need to customize AI-generated presentations for client meetings or internal reports.

• Students and educators who want to fix errors or adapt NotebookLM study materials for their courses.

• Teams handling confidential documents who can't risk uploading sensitive content to cloud services.

Featured In

DeckEdit has never run a paid ad, never sponsored a creator, and never produced a marketing video of its own. Independent creators, tutorial-makers, and tech publications across English, Chinese, and Japanese have written about it on their own. The publications below are a small sample.

• Featured by Computer King Ada (電腦王阿達) as a recommended tool for converting NotebookLM slides to editable PowerPoint.

• Covered by Hong Kong Economic Times (HKET) as a privacy-first solution for document processing.

• Ranked as a top free alternative alongside Canva and Adobe in Tenorshare's 2026 conversion tools review.
