KeepFlash is an AI-powered alternative to traditional bookmark managers and read-it-later apps. It saves the readable content behind webpages alongside PDFs, YouTube videos, files, images, and notes in one searchable library. AI-assisted tags and Topic Pages help structure emerge without forcing users to design folders first. Users can run keyword or semantic search, annotate PDFs, navigate video transcripts and chapters, link notes, and ask questions across selected sources with citations kept in view. KeepFlash is designed for researchers, writers, students, and knowledge workers who need to reuse what they save, not just collect it. A free plan is available with 150 notes, two Spaces, PDF annotations, video notes, AI credits, and up to three Topic Pages.

Questions & Answers

As answered by people managing Eightify App and KeepFlash.

Which are the primary technologies used for building your product?

KeepFlash's answer:

KeepFlash is built with Next.js, React, and TypeScript. It uses PostgreSQL with Prisma for structured data, Meilisearch for full-text search, BlockNote for block-based editing, and AI models for tagging, summarization, semantic retrieval, and source-grounded answers.

How would you describe the primary audience of your product?

KeepFlash's answer:

KeepFlash is designed for researchers, writers, students, deep readers, and knowledge workers who regularly save material for future projects. It is especially useful for people who need to return to exact passages, annotations, video segments, and connected ideas instead of maintaining a simple list of links.

What makes your product unique?

KeepFlash's answer:

KeepFlash keeps the original source context instead of storing only a bookmark. Webpages, PDFs, YouTube transcripts, files, images, and notes live in one searchable library. Editable AI tags, bidirectional links, Spaces, and source-backed Topic Pages help users turn saved material into reusable knowledge.

Why should a person choose your product over its competitors?

KeepFlash's answer:

Choose KeepFlash when you want one workflow for capture, reading, annotation, search, and reuse. It saves readable page content, supports PDF annotations and video transcripts, and combines keyword and semantic search with AI answers that keep supporting sources visible. A free plan is available, so users can evaluate the complete workflow before upgrading.

What's the story behind your product?

KeepFlash's answer:

KeepFlash grew from a simple problem: saving information is easy, but returning to it with the original context is hard. It brings webpages, PDFs, video transcripts, files, and personal notes into one library so saved material can support future research, writing, and learning.
