SECOND BRAIN
Capture everything.
Notes, voice memos, decisions, writing samples, emotional context. Every input trains a living knowledge graph that your twin and agents draw from. Not a filing cabinet — a corpus.
LOOP ENGINEERING · SECOND BRAIN · AGENTS
Your second brain doesn’t sleep.
Parrallium learns how you think, write, and decide. Then it runs your recurring work overnight with a team of AI agents. You wake up to a briefing — not a longer to-do list.

HOW IT WORKS
Three layers. One system.
Other tools give you a notebook or a chatbot. Parrallium gives you a second brain that thinks, a twin that acts, and a crew that works — all connected in a loop.
AI TWIN
It becomes you.
Your twin learns your writing voice, decision patterns, taste, and boundaries. It doesn’t just know your facts — it knows your judgment. A twin with only your data makes generic choices. A twin with your instincts makes yours.
AGENT CREW
They do the work.
Scout researches. Miner clusters. Writer drafts in your voice. QA checks everything against your rules. Your twin delegates to the crew. You delegate to your twin. That’s the loop.
The night shift.
You log off. Your system clocks in.
11:38 PM
You close the laptop.
Your twin already knows tonight’s agenda — which loops to run, which sources to scan, which rules to follow. It’s been watching how you work for weeks.
1:12 AM
Scout finds signal in the noise.
4 subreddits, 2 X search streams, 3 RSS feeds. Hundreds of posts scanned. Scout surfaces 12 candidates. Miner clusters them into 3 pain points worth your attention.
3:47 AM
Writer drafts in your voice.
Two reply drafts and a thread outline, written the way you write — your sentence length, your opener style, your level of directness. QA checks each against your never-say list.
6:59 AM
Everything waits for your yes.
Nothing was sent. Nothing was posted. Every draft sits in your approval queue. Your twin got better overnight, but it still answers to you.
7:00 AM
Your briefing is ready.
Three things done. Two need your call. One thing learned about you. The loop closes — and opens again tonight.
LOOP ENGINEERING
Stop writing to-do lists. Start engineering loops.
A loop is a recurring autonomous workflow: a trigger, a job, a stopping condition, and an output. You engineer it once. It runs every night. It gets smarter every morning.
Overnight Research Loop
AVAILABLE AT LAUNCHMonitors your subreddits, X searches, RSS feeds, and HN keywords. Clusters pain points, surfaces trends, and drafts reply threads in your voice — ready in your approval queue by morning.
Every night, 11 PMMorning briefing + draft queue
Inbox Triage Loop
COMING SOONScans overnight email. Flags urgent items, drafts replies in your voice for non-urgent threads, and summarizes everything you missed into a 2-minute digest.
Every night, midnightInbox digest + reply drafts
Content Loop
COMING SOONTurns the week’s notes, bookmarks, and captured thoughts into post drafts that sound like you — thread-ready for X, newsletter-ready for email.
Every Sunday, 10 PM3 draft posts in your voice
Follow-up Loop
COMING SOONTracks unanswered outbound messages across email and DMs. Drafts gentle follow-ups in your voice so nothing slips through the cracks.
Every 48hFollow-up drafts queued
Autonomy is earned. Never assumed.
Your twin starts in draft-only mode. It earns autonomy through a trust ladder — every correction you make teaches it, and every level it unlocks requires your explicit approval.
Draft-first by default
Your twin proposes. You dispose. Nothing goes out, gets posted, or gets sent without your explicit yes.
Nothing irreversible without approval
v1 never sends, posts, or publishes anything. Everything lands in an approval queue. You review, edit, or reject.
Hard spend caps + full audit log
Set per-loop token budgets. Every overnight action is logged with full context — what the agent did, why, and what it cost.
Your data trains only YOUR twin
Your knowledge graph and voice profile are yours alone. Never shared, never used to train other users’ twins. Export or delete anytime.
I’m an indie developer in the Philippines. I built a multi-agent research team to scan markets for me overnight — four AI agents across Claude Code, Codex, and Cursor. Waking up to their briefings changed how I work. Parrallium is that system, productized. A second brain that doesn’t just store what you know — it acts on it while you sleep.

WHO IT’S FOR
Built for founders, creators, educators, and knowledge workers.
If your best work keeps losing to your recurring work, Parrallium is built for you.
Founders
Hand your twin the overnight market research: the subreddits, the X lists, the competitor threads you never get around to reading.
Creators
Turn the week’s notes and bookmarks into drafts that sound like you, waiting in a queue rather than a blank page.
Educators
Keep a living corpus of your material, and let the crew surface what changed in your field while you slept.
Knowledge workers
Triage the inbox, chase the follow-ups, and summarise what you missed — all before your first coffee.
What it’s designed to do
- Capture notes, voice memos, decisions, and writing samples into one knowledge graph
- Train a twin on your writing voice, decision heuristics, taste, and boundaries
- Engineer recurring overnight loops with a trigger, a job, and a stopping condition
- Review every output in an approval queue — nothing is sent, posted, or published for you
Founding-member feedback coming soon
Parrallium hasn’t launched yet, so there are no customer testimonials to show — and we won’t invent any. Real, consented feedback from founding members will appear here after the first invites go out in August 2026.
Questions.
Your second brain is waiting for a night shift.
