Private Summaries, without uploading a thing

Extractive summaries built from the document's own sentences — zero hallucination, fully offline.

As a confidential professional, you understand the importance of protecting sensitive information. However, cloud-based AI summarization tools have become increasingly popular among professionals seeking to condense large documents into concise summaries. While these services can produce fluent and informative summaries, they often come with a steep price: uploading your document to the cloud, where it may be vulnerable to unauthorized access or manipulation. Moreover, some cloud AI summarizers rely on complex machine learning algorithms that can invent new information not present in the original document, compromising its integrity.

That's why we've created Secretary Bird, a private pdf summarizer designed specifically for confidentiality-bound professionals like you. Our browser extension analyzes documents 100% on-device, using an extractive summary approach that selects only the most important real sentences from your original text. Not only do these summaries preserve the document's authenticity and context, but they also come with a Pro version that adds plain-English summaries in plain sight – without ever leaving the machine. With Secretary Bird, you can enjoy the benefits of AI-driven summarization without compromising your data security or integrity.

How Private Summaries works

In Secretary Bird, our proprietary extractive summarization algorithm analyzes documents 100% on-device, without transmitting any data over the internet. This means that all summaries are generated locally, using only the information present within the document itself. Our approach is based on a simple yet powerful principle: rather than relying on machine learning models or hallucinations, we extract the most important sentences and phrases from each document, ensuring accuracy and reliability.

When you use Secretary Bird, you can expect to see a concise summary of your document, with all relevant information preserved in its original context. Each sentence and phrase is linked directly to the source passage, so you can easily refer back to specific points discussed in the conversation or research report. The deterministic nature of our algorithm means that it will never introduce false or fabricated information - every summary is grounded in the actual content of the document. In Pro mode, we take this capability a step further with abstractive summaries and ask-the-document Q&A functionality, allowing for even more nuanced exploration and analysis of your documents.

How to use it

How it compares

ChatGPT reasons more deeply and writes more fluently on public material. Where Secretary Bird differs is the architecture: for documents you're not allowed to upload. The document is never uploaded, so using it doesn't hand your client's data to a third party.
