SlideSleuth makes the important slides inside online videos searchable, then combines visual analysis with the presenter’s matching commentary—so you (or your agent) can quickly understand what was shown, what was said, and why it matters.
Interactive demo opens without sign-in Desktop plans start at the founder launch price of US$4.99/month.
Demo video
The problem
You remember the presenter discussing a chart, diagram, or article you want to review, and need to find where it first appears. The time you waste finding the slide should be time spent understanding it.
A screenshot loses the presenter’s explanation. A transcript loses the chart, table, or diagram it was describing. Neither one on its own tells you what actually mattered.
Trying to understand a section by playing it again can cause the brain to “zone out,” when what you really need is to review the material from another angle.
Search can locate a video, and a transcript can reveal what was said—but the most important information may be a chart, diagram, or table that only ever appeared on screen.
Product
Slide Focus
SlideSleuth finds the timepoint of each information-rich slide, and analyses the visual content of the slide in the context of the presenter’s matching commentary.
Topic Focus
Topic Focus summarises the spoken commentary into the important subjects and key messages, then lets you jump directly to the sections where each is explained.
How it works
Paste the link to a supported public online video into the desktop app (currently only YouTube is supported).
SlideSleuth finds the precise slide start points, combines the video’s visual and spoken content to understand them, and summarises the spoken commentary into the video’s key topics and messages.
Review the results as a visual list that lets you jump to the right video moments whenever you need more context.
For you and your agent
Investigate the video yourself in SlideSleuth Desktop, or let a compatible AI agent use SlideSleuth’s specialised video-analysis tools on your behalf. It’s one underlying capability, available through two complementary workflows.
For you
Download the desktop app to explore the included examples. An active Plus or Pro plan lets you analyse public YouTube videos of your choice, then save, revisit, and export what you find.
Get the SlideSleuth desktop appFor your agent
Use SlideSleuth MCP to search and analyze all the spoken text, then follow time-stamped video links to the exact moments.
Agent access is local and enabled by default, with a user-controllable setting. SlideSleuth’s agent integration is tested for compatibility with the macOS ChatGPT app and the macOS Claude app. Other MCP-compatible hosts may work, but are not currently tested.
Whether you investigate the video yourself or delegate the work to an agent, SlideSleuth turns hours of video into evidence you can actually use.
Benefits
Reviewing material from a different angle—seeing a slide and its explanation together, rather than replaying the video again—helps ideas stick instead of becoming background noise.
Save useful videos, return to previous analyses, and keep important material within reach.
Turn your analysis into a cleaner document for reviewing, sharing, or keeping with your notes.
