About
The Cognitive Arsenal
Jalaran is a unified AI workspace that bridges daily productivity with specialized professional work — 85 modules across 13 arsenals, in one disciplined environment.
What is Jalaran?
Jalaran is a personal productivity SaaS built for engineers and analysts who are tired of juggling fragmented tools. Instead of switching between separate AI chat interfaces, analysis dashboards, news aggregators, and note apps — Jalaran brings them all into one organized workspace.
The name jalaran — from Javanese — means the cause, the reason, the underlying logic behind things. The product's core premise: your tools should be the underlying logic of your workflow, not friction inside it.
The Arsenal
Always open
The two that stay pinned: a conversation with room for every problem at once, and a reading feed that condenses your sources instead of adding to them.
Where the day is organised
Notes, tasks and a calendar that share one set of records, so your board and your week can never quietly disagree.
Where things get made
The modules that produce an artifact — trained models, converted files, narration, an animated character, a finished episode and the package that publishes it.
Work that runs itself
A reason-and-act agent that drives read-only tools across your own data to finish a multi-step goal, and shows every step it took.
The testing arsenal
Purpose-built for QA professionals — test strategy, player-experience risk, structured bug reports, execution tracking, and browser suites that run on a schedule.
The career toolkit
An end-to-end funnel for landing the role — opportunities, applications, the people who refer you, documents, interview practice and the negotiation at the end.
The knowledge desk
The research desk: long-form drafting, PDF reading, a Zettelkasten vault, references, recall, reflection, and language tools for English and Indonesian alike.
The strategy suite
A strategy-and-risk toolkit tuned for Indonesia — frameworks, valuation, metrics, argument analysis, ESG, regulation, tax and contracts.
The signals bench
Hardware and signals work — datasheet answers with real page citations, firmware that knows its memory budget, spectra, fault simulation and calibration drift.
The data lab
Classical statistics done honestly: tests with their assumptions reported, forecasts measured against a naive baseline, and figures that export as vector for print.
The dev toolchain
A local toolchain — write it, fix it systematically, verify it, and check the schema underneath before it reaches production.
The security bench
Find what should not be there: personal data in documents, secrets in source, and the ISO 27001 controls you have never actually assessed.
The Builder
Jalaran is designed and engineered by Hendry Rama Sethiawan — a full-stack software engineer and AI/ML practitioner based in Indonesia.
This project is a direct product of the problem it solves: a single workspace built for the way engineers actually work — context-heavy, tool-switching, and data-driven.
