FAQ 01
What is SecondBrain Cloud?
It is a private AI operating system: a knowledge vault that turns your sources into cited, searchable memory, plus a team of always-on AI agents that work that memory for you 24/7.
Everything you read, write, and decide becomes a private, searchable memory. Then a team of always-on AI agents works that memory for you, around the clock, with cited answers and zero hallucinated facts.
Ingest queue
Memory pages
Cited answer
Answers stay connected to the sources, notes, and decisions behind them.
SEE IT IN ACTION
Each agent specializes. Together they orchestrate. Every answer is grounded in your private vault and cited. Pick a workflow and watch it work — live, with sample data, no signup.
PRODUCT THESIS
A private layer for research, notes, files, calls, and decisions, worked by a team of autonomous agents. Searchable, connected, cited, and always-on.
PRIVATE MEMORY
Every source you save strengthens a private vault only you can query.
24/7 AGENTS
Specialized agents prep your calls, triage your inbox, and watch your numbers.
GROUNDED ANSWERS
Every answer traces back to your sources, and flags what it does not yet know.
LIVING GRAPH
People, topics, sources, and decisions connect into a navigable graph.
THE LOOP
Capture what matters, structure it into memory, then let agents query it, research it, and act on it, with citations every step.
Sources, notes, files, and calls land in one clean lane.
Durable pages with summaries, links, and evidence trails.
Concepts, people, and decisions become a connected graph.
Agents answer, research, and act on your memory 24/7.
HOW IT WORKS
01
Drop in sources, notes, calls, and decisions — or let an agent ingest them for you.
02
SecondBrain turns them into linked, cited memory that compounds over time.
03
Always-on agents recall, research, and act on that memory while you sleep.
SecondBrain keeps your sources, summaries, links, and answers connected so important context is never lost.
Save links, PDFs, notes, documents, and transcripts with their source trail intact.
Convert raw material into summaries, topics, decisions, and linked pages.
Get grounded answers with the pages and sources behind each response.
See people, concepts, sources, and decisions as connected memory.

The essentials on private memory, source-backed answers, graph navigation, and what makes SecondBrain different.
It is a private AI operating system: a knowledge vault that turns your sources into cited, searchable memory, plus a team of always-on AI agents that work that memory for you 24/7.
A chatbot forgets between sessions. SecondBrain keeps durable, linked memory and runs autonomous agents on it around the clock, so the work continues even when you are offline.
Prep your meetings, research topics across the web and your vault, triage your inbox, monitor your metrics, and draft content in your voice, all grounded in your private knowledge with citations.
No. Every answer is grounded in your vault with source citations, and the agent explicitly flags what it does not know yet instead of guessing.
URLs, text, markdown, PDFs, DOCX, and TXT files, plus call transcripts. You add them, or an agent ingests them for you.
Founders, operators, researchers, creators, and teams who need reliable recall from their own material and a tireless agent to act on it.
Early users ingesting transcripts, papers, meeting notes, and raw thought streams — turning them into cited, linked, timeline-aware knowledge.
“I stopped losing context between projects. My second brain answers questions I didn't know I'd already solved six months ago — with citations.”
“The timeline preservation is the killer feature. Every ingested source stays dated and linked — it's a git log for my thinking.”
“Ingested three years of meeting transcripts in an afternoon. The knowledge graph surfaced connections I never noticed.”
“The [[slug]] citations changed how I trust LLM output. I click through and verify before I ship. That's non-negotiable for me now.”
“It feels like a premium AI memory workspace rather than another note app. Minimal, fast, and the graph view is genuinely useful.”

“We replaced a Notion wiki maintained by three people with this. Ingestion is automatic, truth stays compiled, nobody argues about structure.”
“My MacBook feels like a command center now. Dashboard at a glance, query when I need it, wiki when I'm reading deeply. That's the whole stack.”
“The ingest queue watching sources turn into connected memory pages is oddly satisfying. It's the only SaaS I've opened a second tab just to watch.”
“I pasted a 90-minute YouTube transcript and got back a structured wiki with entities, events, and relations. That workflow used to take me a full Sunday.”
“Premium feel without the bloat. It respects my keyboard, my data, and my time — which is rare for AI tools in 2026.”
