Turn every podcast into a brain you can search.
Earmark transcribes any YouTube video, podcast, article, or X post — then extracts a timestamped knowledge card, follows the people you care about, tracks the stocks and funds they mention, and synthesizes where it's all heading.
Magic-link or passkey — no password required.
▶ The one-minute tour — narrated, with sound.
You can't listen to everything. Earmark does.
It's a personal intelligence layer over the firehose of podcasts, interviews, and posts — equal parts structured knowledge cards, one-tap clipping, and a research terminal. Paste a link and Earmark does the listening, the note-taking, and the connecting, so the signal compounds instead of scrolling away.
Everything it does (See demo)
One tool to capture, dissect, track, and synthesize the media you learn from.
Timestamped knowledge cards
Every video becomes an executive summary plus claims, concerns, frameworks, action items, and verbatim quotes — each citing a clickable [HH:MM:SS].
One-tap Snips
Grab any moment as a shareable clip card with a branded image and a 1080² audiogram video — perfect for sharing the exact 45 seconds that mattered.
Share & listen to any card
Publish an episode’s full knowledge card at a public link with its own OG image — and hit play to hear the executive summary, TL;DR, and key takeaways in a warm AI voice, in the app or on the share page.
Follow the people you trust
Person pages compound everything someone has said across every appearance — their main points, concerns, and best quotes, in one evolving profile.
Stocks & watch list
Cashtags like $NVDA link to live price, chart, and the exact timestamped clips where they were mentioned. Three sub-lists, sorted by mentions, with import/export.
Funds & live SEC 13F
Follow 13F managers and read their latest EDGAR filings and holdings with quarter-over-quarter deltas — or populate any fund’s status and portfolio from the open web.
Concepts “Landscape”
A Claude Opus 4.8 synthesis across your entire library: the themes gaining momentum, where the conversation is heading, and the live tensions between sources.
Narratives — highlight to distill
Highlight any phrase in a knowledge card or transcript and save it to a curated, priority-ranked store — the lines worth memorizing, emphasizing, or folding into your thesis.
Interactive knowledge graph
An animated, Obsidian-style graph of how your concepts and core-memory categories connect — through the episodes, people, and tickers they share. Drag, zoom, hover, and click through.
Ingest anything
YouTube, podcast RSS, web articles, and X posts — each is probed, then transcribed or text-extracted into the same structured knowledge card.
Translate to English
One click renders any foreign-language episode’s card — headline, summary, and points — in fluent English, and saves the translation to memory.
AI chat & voice
An Opus-4.8 assistant that knows your whole library and the platform, plus a real-time voice assistant you can simply talk to.
Groups & Suggest sources
Organize people into topics, then let AI surface the leading voices, scholars, and sharpest critics worth following — add any of them in one tap.
Channels — scout before you ingest
Add a YouTube channel and Earmark summarizes what it focuses on and lists its top videos relevant to your concepts — without transcribing anything. A button suggests similar channels grounded in your landscape.
Core memory
Save any insight, synthesis, or translation to a personal brain that bridges to your Obsidian vault and Claude Code for deeper work.
Agentic CLI & MCP
Push and pull from the command line or your AI harness — a scoped token lets Claude Code, Claude Desktop, and Cursor add episodes and pull knowledge cards as you. Developer preview.
Passwordless & private
Magic-link and passkey sign-in, role-based access, and an owner audit log. No passwords to leak — your library stays yours.
Community & Trollbox
Publish a submission to the public Community feed for others to discover — anonymously — and trade takes in the live Trollbox.
AI video summaries
Generate an AI-hosted video recap — a HeyGen avatar reading a Claude-written script — for any episode or your whole Concepts Landscape.
Teams
Create a team, invite members by email, and share submissions into a private space — full knowledge cards, snips, and a merged timeline of what the team is learning from.
See it in action
Real screens from the app — not mockups.
Every minute, dissected and timestamped
An executive summary up top, then the claims, frameworks, and verbatim quotes — each one a clickable jump back into the source. No more re-scrubbing a three-hour episode.
A living synthesis of your whole library
Opus 4.8 reads across everything you’ve ingested and tells you what’s rising, where it’s heading, and where your sources disagree — refreshed as you add more.
Follow the smart money, from the filings
Live EDGAR 13F holdings with quarter-over-quarter deltas, cross-linked to the episodes and tickers where each manager actually came up.
The tickers they keep bringing up
Cashtags detected across your library, ranked by how often they’re mentioned, with live quotes and the clips behind every call.
People that compound over time
Every appearance folds into one profile — their through-lines, their best quotes, and the latest research on what they’re saying now.
How it works
Paste a link
Drop in a YouTube, podcast, article, or X URL. Earmark grabs captions or audio and transcribes it with timestamps — captions first, so it’s free when it can be.
AI extracts the knowledge
Claude turns the transcript into a structured card — summary, claims, frameworks, quotes — every line citing the exact second it was said.
It compounds
Snip moments, follow the speakers, track their tickers and funds, and read a living synthesis of where your whole library is heading.
