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.
Webpages, PDFs, YouTube, ideas. No more scattered tabs.

Saving is only useful when you can find it again.

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

One place to come back to

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

As your library grows, KeepFlash helps structure emerge.

AI tags reuse your existing categories first. Auto Wiki groups related saves into Topic Pages, compiled pages you can read, revisit, and keep asking about.

Keep working

Read, annotate, write notes, and ask AI 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

Ask AI with saved sources and get answers with citations

Use the note or Topic Page as context instead of starting from a blank prompt.

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

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