About this app

Pocket Search Engine provides a powerful semantic search tool that works entirely offline. Search through your collection of PDFs and HTML files without needing an internet connection.

For Researchers and Knowledge Workers: Whether you’re a writer, student, or journalist, effortlessly search within your curated knowledge base on your device, keeping your documents private and your searches secure.

Offline: Access information offline, from car manuals to survival guides. Ideal for situations where connectivity is a challenge, ensuring you have the answers when you need them the most.

Semantic and Syntactic Search:
Using semantic search (aka meaning-based search), the engine understands the meaning of your query. This means it looks beyond exact word matches to grasp the context and meaning—helping you find the right answers even when the phrasing isn’t identical. You can also perform exact keyword searches (syntactic) by enclosing your query in quotes if needed.

Offline & Privacy Focused:
Every search and data process is carried out locally on your device, eliminating the need for internet access and keeping your data private.

Pre-Populated Resources (Optional):
For added convenience, you can download a pre-populated database that includes resources like car manuals and survival guides. This way, even if you’re off the grid, you’ll have access to essential information right in your pocket.

By combining an internal database, smart search algorithms, and complete offline functionality, PocketSearchEngine brings you a powerful way to find the answers you need, wherever you might find yourself.

Ratings and reviews

the PDF indexing for files under 20MB is working great, but viewing specific sections is sometimes slow or shows a blank page. Larger files over 20MB index well, but viewing them is slow, which is expected. Overall, I'm happy with the indexing but want to see performance improvements for viewing.

This app is a hope to be king of local text searches on phone though currently it supports pdf. Though its at early stage yet as they say there is hope and this app is indeed for local text searches on phone. Kindly support the Dev by using the app and providing feedback. The dev is very responsive. I am sure this app is a king in making.

Once you add in your books, this is a great search so that really lets you quickly being up right where it is located and in which book.
