[Home](https://marolabs.kr/) / [Products](https://marolabs.kr/products/) / Maro Portal macOS # Maro Portal: your AI work, kept and checked AI tools forget. Every new session starts from zero, and the decisions behind your work disappear into old chats. Maro Portal is a local-first workspace for the Mac where the work you hand to AI, your conversations, and your decisions keep living. [Request access](https://marolabs.kr/request-access/)[FAQ](https://marolabs.kr/support/) ![Screenshot of the Maro Portal macOS app: the knowledge map, with six illustrated topic islands and a note preview panel](https://marolabs.kr/img/portal-map.jpg) ## What is inside Everything you hand off, decide, or learn stays as a record you can search, revisit, and build on. - **Central conversation**: One place to talk to Maro and hand off work, instead of starting a new chat for every task. - **Personal wiki**: Daily briefings, decisions, and research are kept as pages, each with its sources, revisions, and open questions. - **Knowledge map**: Records grouped into topics and links, with seven ways to look at them, so you can see what you know and how it fits together. - **Work routes and chronicle**: Every work stream shown as a route of steps, plus a chronicle that replays past work as a story with what was learned. - **Library**: One home for source material: a wiki shelf, a second brain, the knowledge map, a viewer for books, PDFs, photos, and video, and a knowledge garden. - **Work encyclopedia**: Rules, concepts, and lessons learned, sorted by category, so past mistakes become a checklist for later work. ## Six steps per task Every task has a beginning, a review, and an end. You can see which step it is on at any time. - **Born**: A task is opened from the conversation, with your request kept in its original wording. - **Checked**: Before it runs, the task is checked, so work starts from a clear request rather than a guess. - **Run**: An AI worker does the work in its own session. - **Evaluated**: A separate reviewer checks the result. The review receipt names the provider, and a partial pass stays partial. - **Harvested**: Outputs are filed in dated work folders, and lessons go to the work encyclopedia. - **Closed**: The task closes with its record. Nothing counts as done until it has been through review. ### Built around your records - **Model-neutral**: Providers are replaceable parts. Maro Portal connects to Anthropic Claude, OpenAI Codex, and an on-device model, and a task keeps its history when the model changes. - **Local-first**: A native macOS app with a local Node.js server on the same Mac. Your records stay in the app's data folder on your own Mac. - **Decisions on the record**: Decisions are logged with their original wording and where they were said, so later work can check what was actually decided. - **Lessons come back**: What went wrong is written down as a lesson and filed in the encyclopedia, so the same mistake is harder to repeat. ## Screens from the app Real screenshots of Maro Portal on the Mac. The interface is in Korean. ![Screenshot of the Maro Portal macOS app: the personal wiki index, a list of dated pages with a preview panel](https://marolabs.kr/img/portal-index.jpg) Personal wiki: decisions, research, and briefings kept as pages.

A separate reviewer checks the work before it closes, the review receipt names the provider, and a partial pass is never rounded up. ## Maro Writer No. AI drafts become part of the manuscript only when you adopt them, and the original is kept separately. Long-form and serialized fiction. It has chapter-by-chapter story memory, a glossary of several hundred martial-arts terms, a name finder, and genre-specific themes. Maro Writer has a Claude connection for co-writing. You choose AI-led, writer-led, or writing together for each work. Maro Writer grew out of Maro Portal's writing extension and became its own macOS app on September 29, 2026. ## Maro Portal ### Hand off work and get it back reviewed 1. **Open Maro Portal** on your Mac. The desk is the first screen. 2. **Connect the AI providers** you want to use: Anthropic Claude, OpenAI Codex, or an on-device model. 3. **Talk to Maro** in the central conversation and hand off a task. 4. **Follow the task** through its six steps. A separate reviewer checks it before it closes. 5. **Come back to it later** in the personal wiki, the knowledge map, and the chronicle. ## Maro Writer ### Start a work and write together 1. **Open the bookshelf**, enter a title and genre for a new work, then create and open it. 2. **Pick a co-writing mode** for the work: AI-led, writer-led, or writing together. 3. **Write chapter by chapter.** Select a passage to ask for changes right there, compare, and apply. 4. **Adopt only what you like.** Drafts join the manuscript when you adopt them; the original is kept separately. 5. **Use the genre tools.** The glossary and name finder sit beside the manuscript. ## Maro Portal | | | | --- | --- | | Operating system | macOS | | How it runs | Native app plus a local Node.js server on the same Mac | | AI | The providers you connect: Anthropic Claude, OpenAI Codex, or an on-device model | | Interface language | Korean | ## Maro Writer | | | | --- | --- | | Operating system | macOS | | How it runs | Native macOS app | | AI | Claude connection for co-writing | | Interface language | Korean | --- Maro Labs · South Korea · founder@marolabs.kr · https://marolabs.kr/ · Built with Claude ========== --- title: Security & data | Maro Labs url: https://marolabs.kr/security/ language: en alternates: ko https://marolabs.kr/ko/security/ ; ja https://marolabs.kr/ja/security/ updated: 2026-10-09 --- > How Maro Labs handles data: Maro Portal keeps records on your own Mac, AI calls go only to the providers you connect, work is checked by a separate reviewer, and AI drafts join a manuscript only when the writer adopts them.

Your records stay in the app's data folder on your own Mac. - **You choose where AI calls go**: AI calls go out only to the providers you connect: Anthropic Claude, OpenAI Codex, or an on-device model. - **History survives a model change**: Providers are replaceable parts. When the model changes, a task keeps its history. - **Your manuscript stays yours**: In Maro Writer, AI drafts join the manuscript only when you adopt them, and the original is kept separately. ## How work is checked - **Separate reviewer**: Work is checked by a separate reviewer before it closes. - **Named receipts**: Each review receipt names the provider that did the review. A partial pass is never rounded up to a full one. - **Decisions are traceable**: Decisions are logged with their original wording and where they were said. ## This website - This website is static HTML, with no sign-up, no forms, and no advertising or tracking scripts. - We are contacted by email only, at founder@marolabs.kr. - The company is listed by country (South Korea); no personal home address is published.

It makes Maro Portal and Maro Writer for macOS, and works through a record, review, decide loop. Built with Claude. [Home](https://marolabs.kr/) / About # About Maro Labs A Korea-based software studio, founded in April 2026, making AI-native workspace tools for macOS. Maro Labs was founded in South Korea in April 2026 by Maro. Building software with AI every day, we kept running into the same problem: the tools lost context along the way, and the decisions behind the work disappeared into old chats. Maro Portal began as the workspace we needed for our own work: one place where tasks, conversations, and decisions stay on the record and nothing closes without review. A question in May about how to start a martial-arts novel grew into its writing extension, and in September 2026 into a separate app, Maro Writer. We believe everyone who does serious work with AI needs the same thing: context that stays, work that is checked, and decisions that can be traced. ### The problem we work on - **Context gets lost**: Each AI session starts fresh. Plans, constraints, and earlier decisions have to be explained again, or they quietly get dropped. - **Work is scattered**: Results live across many chats, tools, and folders. It is hard to see what was done and why. - **AI work is hard to check**: When several AI tools work on one project, it is hard to review what each produced and keep them moving in one direction. ## Record, review, decide Every piece of our work runs through the same six-step loop inside Maro Portal. It is recorded, checked by a separate reviewer, and closed only with a decision on the record. Maro leads and decides; AI workers plan, build, and review in parallel. - **Born**: A task is opened from the conversation, with your request kept in its original wording. - **Checked**: Before it runs, the task is checked, so work starts from a clear request rather than a guess. - **Run**: An AI worker does the work in its own session. - **Evaluated**: A separate reviewer checks the result. The review receipt names the provider, and a partial pass stays partial. - **Harvested**: Outputs are filed in dated work folders, and lessons go to the work encyclopedia. - **Closed**: The task closes with its record. Nothing counts as done until it has been through review. ### On the record (October 8, 2026) closed work records : 470 closed after review : 424 test files : 493 product build receipts : 117 ## How we build - **Evidence first**: Look at the real thing, then reason, then conclude. A claim of "done" is checked again, not taken on trust. - **Done means usable**: If a feature works but is hard to use every day, it is not finished. Done is usable, correct, safe, and verifiable together. - **Use what exists**: Before building something new, find what is already there. Wiring comes before new parts. - **Calm above, busy below**: The first screen stays quiet. The complicated work happens under the surface, and you go to it only when you need to decide something. - **Rules guide, bans are explicit**: Rules give direction rather than lock things down. What must never happen is written out plainly. - **Failures are assets**: A failure is recorded, not hidden: what was expected, what happened, and the smallest check that would have caught it. ## Built with Claude Claude is our main tool. Over 70% of our important work, meaning direction, design, planning, and the key reviews, runs on Claude. Other AI tools take the rest, mainly implementation and second reviews. Claude is also connected inside both apps: as a provider in Maro Portal, and for co-writing in Maro Writer. Maro Writer was specified in a Claude Code session on September 27, 2026. ### Model-neutral by design Maro Portal treats AI providers as replaceable parts, so other models also implement and give second reviews. ## Company facts Company : Maro Labs Founded : April 2026 Founder : Maro Based in : South Korea Team : Founder-led, working with parallel AI workers What we make : AI-native workspace tools for macOS Products : [Maro Portal](https://marolabs.kr/products/maro-portal/), [Maro Writer](https://marolabs.kr/products/maro-writer/) Contact : [founder@marolabs.kr](mailto:founder@marolabs.kr) Languages : Korean, English (website also in Japanese) ## Want to use Maro Portal or Maro Writer?
