A searchable, askable personal knowledge library

Turn scattered links, PDFs, videos, and notes into a library you can actually use later.

Save webpages, files, YouTube videos, and quick thoughts into KeepFlash. AI tags what you keep, connects related material, and can compile clusters into Topic Pages so your next writing, research, or study session starts with context.

No card required · 150 notes free · PDF annotations and YouTube video notes included
Capture first

Webpages, PDFs, YouTube, ideas — no more scattered tabs.

When you find something worth keeping, save it into KeepFlash. Search, annotate, ask, and organize later — you don't need to decide where it belongs upfront.

KeepFlash
Everything flows into one searchable library
Links, files, videos, and notes all land in one place you can search and ask.
Links

Save readable webpages with source retained

Articles, references, and pages are saved with their original link and content.

PDFs

Upload documents and annotate them

Papers, reports, and files can be highlighted, annotated, and revisited.

Videos

Save YouTube videos with transcript and chapters

Watch transcripts, jump to chapters, and take notes alongside the video.

Notes

Write quick notes and connect them to saved material

Drafts, clues, and ideas captured quickly, then linked to your library.

From bookmarks to knowledge base

Saving is not the end — being able to find it again is the point.

KeepFlash preserves the source, body, annotations, tags, and context so you can get back to the right paragraph, video segment, or note later.

Fragments
Saved in different places
Saved before, hard to find again
You remember it mattered, but not where it went
KeepFlash

One place to come back to

Search across links, PDFs, videos, and notes
Keep reading, annotating, and revisiting in context
Self-organizing

As your library grows, KeepFlash helps structure emerge.

AI tags reuse your existing categories first; Auto Wiki discovers related material and compiles it into Topic Pages you can read, revisit, and keep asking about.

AI tags

New notes land with useful tags

KeepFlash prefers your existing tags and only creates new ones when the note clearly needs them.

Auto Wiki

Related notes can become Topic Pages

When patterns emerge, Auto Wiki can group source notes and compile a page you can read, revisit, and ask about.

Related topics

The connections come back to the note

Topic chips keep the trail visible, so saved fragments become a connected library instead of another pile.

Keep working

Read, annotate, write notes, and ask AI — all in the same context.

Open any saved item and continue editing notes, annotating PDFs, viewing video transcripts and chapters, or handing the current content to AI as context.

Block editor

A rich editor that feels natural for real notes

Use headings, lists, callouts, media blocks, and slash commands in one calm editing flow.

Read in context

Highlight a PDF or jump through transcript and chapters

Stay close to the material while reading, annotating, and revisiting the important parts.

Ask with context

Send selected content into AI chat and get answers with citations

Use the note itself as context instead of starting from a blank prompt.

Find it again

When you remember "I saved that before," KeepFlash helps you get back to the thread.

Use keywords, semantic search, tags, related topics, and AI chat to bring scattered material back into your current research, writing, and study.

Connected notes

Move between linked ideas without losing the trail

Follow highlights, notes, and related references as if they were spread across the same desk.

Quiet retrieval

Find the line, clip, or note you remember keeping

Search and return to the right material without rebuilding the context from scratch.
