NDLedger

If you have ever had a brilliant idea during an AI conversation only to lose it in a sea of chat history, NDLedger is the solution you have been looking for. NDLedger is an external memory tool designed specifically to capture, organize, and preserve the valuable insights that emerge from your conversations with AI tools like ChatGPT, Claude, Gemini, Grok, and Perplexity. Instead of letting your best thinking disappear into a chronological list of chats, NDLedger automatically extracts every decision, commitment, task, insight, and pivot from your conversations and stores them in a structured, searchable library. The process is remarkably simple: you paste a transcript or record audio directly in your browser, and the system handles the rest. Claude Haiku reads the session, identifies the key pieces of information, and assigns each one to one of seven predefined categories. Your original transcript is deleted immediately after extraction, so your privacy is protected from the start. NDLedger is built for solo founders, neurodivergent entrepreneurs, and knowledge workers who do their best thinking in conversation and need a way to make that thinking stick. There is no tagging, no note-taking, and no system to maintain. You just add conversations, and your library builds itself. Browse by topic, search across everything, or explore connections in an interactive mind map. NDLedger transforms scattered chat history into an organized knowledge base that grows with you.

AI-Powered Insight Extraction

NDLedger uses Claude Haiku to read every conversation you paste and automatically extract the most important pieces of information. The AI identifies decisions, commitments, tasks, insights, and pivots, then assigns each one to a relevant category. This happens without any manual input from you, so you never have to tag, sort, or organize anything yourself. The extraction is thorough and designed to capture the essence of your conversation.

Audio Recording with Automatic Transcription

You are not limited to pasting text transcripts. NDLedger also lets you record audio directly in your browser. Whether you are brainstorming out loud, dictating notes from a meeting, or capturing a spontaneous idea, the built-in recorder works seamlessly. OpenAI Whisper handles the transcription automatically, turning your spoken words into text that Claude can then analyze and extract insights from, all in one smooth workflow.

Interactive Mind Map

Your insights do not have to live in isolation. NDLedger includes an interactive mind map that visually connects topics and ideas across all your sessions. This feature helps you spot patterns, relationships, and connections that you would never notice by scrolling through a linear chat history. The mind map makes your knowledge visible and explorable, turning a collection of notes into a dynamic web of ideas.

Full-Text Search with Filtering

Finding a specific decision or task from weeks ago is as simple as typing a keyword into the search box. NDLedger offers full-text search across every insight you have ever extracted. You can also filter by type to narrow your results to only decisions, only tasks, or only insights. This makes it incredibly fast to locate exactly what you need without digging through endless chat logs.

Solo Founders Capturing Product Decisions

As a solo founder, you make dozens of product decisions during AI brainstorming sessions. A feature priority, a pricing strategy, or a technical direction can get lost in the flow of conversation. With NDLedger, you paste your chat transcript and every decision is extracted and stored. Weeks later, when you need to recall why you chose a particular approach, you can search by topic or filter by decisions to find the exact reasoning, saving hours of frustration.

Neurodivergent Entrepreneurs Managing Ideas

For neurodivergent entrepreneurs, traditional note-taking systems can feel overwhelming and hard to maintain. NDLedger removes that burden entirely. You do not have to remember to tag, categorize, or organize anything. You simply have your conversation, and the system does the rest. The structured output helps reduce cognitive load, and the mind map provides a visual way to see how your ideas connect, making it easier to navigate complex thinking.

Knowledge Workers Synthesizing Research

Knowledge workers often use AI to explore topics, summarize research, or debate ideas. These conversations are rich with insights, but they are hard to revisit later. NDLedger turns those sessions into a permanent, searchable reference library. You can quickly find a key insight from a conversation you had three months ago, filter by tasks to see what actions you committed to, or explore the mind map to discover how different research topics relate to each other.

Teams Preserving Strategic Discussions

Even if you work alone, you may have strategic discussions with AI about business direction, marketing campaigns, or operational improvements. NDLedger ensures these discussions are not wasted. Every pivot in your thinking, every commitment you make to try a new approach, and every insight that shapes your strategy is captured. You can revisit your strategic evolution over time, ensuring that your best thinking from every conversation is preserved and accessible.

Which AI tools does this work with?

NDLedger works with any AI tool you use. You can paste transcripts from ChatGPT, Claude, Gemini, Grok, Perplexity, or any other conversational AI. The system is designed to process text from any source, so you are not limited to a specific platform. You can also record audio directly in the browser, which works for any kind of verbal brainstorming session.

Is my data private?

Yes, your privacy is a core part of NDLedger. The original transcript you paste is deleted immediately after the extraction process finishes. Only the structured insights are stored in a database that only your account can read. The system uses row-level security to ensure that no one else can access your data. NDLedger never shares, sells, or trains on your data.

What if the extraction misses something important?

While Claude Haiku is highly effective at identifying decisions, tasks, and insights, no automated system is perfect. If something is missed, you can always add it manually by editing the extracted insights. The goal is to capture the vast majority of valuable information without any effort on your part, but you retain full control to refine your library as needed.

How do I delete my data?

You can delete your data at any time directly from your account settings. NDLedger gives you full control over your information. When you delete data, it is permanently removed from the database. There are no complicated processes or waiting periods. Your privacy and ownership of your insights are fully respected.
