Long videos. Made navigable.

Turn long YouTube videos into a Map you can navigate.

SourceLayer sits beside YouTube and turns long videos into clickable sections and ideas — each linked to the transcript, exact timestamp, and original source.

Built for people who actually use what they watch.

Keep the depth.
Lose the digging.

01

Learning something new

Turn a long tutorial into something you can return to. Navigate explanations, methods, examples, and recommendations.

02

Researching a decision

Find the thesis. Inspect assumptions. Jump to risks. Return to evidence.

03

Following a deep conversation

Give arguments, stories, examples, and conclusions a shape you can follow.

04

Returning to something valuable

You remember the idea. You don't remember minute 73. SourceLayer does.

From play button to useful idea.

Three steps.

01

Open YouTube

SourceLayer sits beside supported videos while you watch normally.

02

Analyse

Click Allow and analyse. SourceLayer builds the Map.

03

Navigate

Scan the sections, open an idea, and jump straight to its timestamp.

The video stays the source. SourceLayer gives you a better way through it.

“Honestly saves me so much time on long podcasts. If I remember something from earlier I can just find it again instead of scrolling around trying to work out where it was.”
Mina K.Verified SourceLayer user
“I use this for tutorials all the time now. Way easier when I need to come back a few days later and find one specific explanation.”
Omar H.Verified SourceLayer user
“Really useful for long videos and definitely saves me time. Took me a little bit to get used to the layout at first, but now I use it whenever I know I’ll want to come back to something.”
Ravi P.Verified SourceLayer user
“The timestamps are probably my favourite part. I’ll remember an idea but never remember where it was in a two-hour video. This fixes that.”
Ben C.Verified SourceLayer user
“Really useful extension.”
Aisha M.Verified SourceLayer user
“I didn’t really want another AI summary tool. I like that this keeps everything connected to the actual video so I can check the context myself.”
Ramon S.Verified SourceLayer user
“Absolute time saver.”

Built differently from a summary tool.

The source always wins.

Why not just use ChatGPT?

You can paste a transcript into ChatGPT and get an answer. SourceLayer gives the video itself a persistent structure beside the video.

Chat

Transcript → question → answer

SourceLayer

Video → Map → idea → context → timestamp → source

Chat gives you an answer. SourceLayer gives the source a structure.

Never lose the original

SourceLayer's Map is an interpretation. The original video remains the evidence.

Questions before you add it.

SourceLayer can give you a quick overview, but the Map is the core experience. It preserves the structure so you can decide what deserves your attention.

No. It helps you decide what to watch, where to go, and what to return to.

Creator chapters are useful when they exist. SourceLayer goes deeper by showing useful ideas and analytical objects inside the broader discussion.

Yes. Ideas remain connected to supporting transcript and timestamps so you can return to the original source.

SourceLayer is designed for long, knowledge-heavy YouTube videos with usable source material. Exact launch coverage will be confirmed in the released extension.

Yes. Free includes 3 full Maps every month, with the same core Map, timestamps, and supporting transcript experience. Pro increases the allowance to 100 Maps each month.

Check the extension listing and privacy policy before installing. They describe the permissions and data handling for the released version.
