Keep your work
flowing.

Deskflow Labs plans and builds software that eases information overload, improves efficiency, and reduces decision fatigue in everyday desk work.

We look for the small frictions in daily work and solve them as tools that fit naturally into your workflow — rather than adding more complex steps.

ABOUT

Starting from the small frictions inside real work.

Deskflow Labs’ products are not born from ideas on paper alone. They start from the frictions felt in actual desk work — running a business, e-commerce tasks, research in the browser, preparing documents, and back-and-forth with AI.

Each problem may be small, but repeated every day they drain a great deal of time and focus. Deskflow Labs builds software that reduces that burden so people can return to the work they actually want to do.

STORY

Why we started Deskflow Labs.

Working on a computer every day, I kept accumulating half-finished tabs, notes, saved documents, and conversations with ChatGPT — until simply finding the right information had become work in itself. I had added convenient tools, yet there was ever more to manage.

To improve that, I believe it matters more to reduce small burdens one at a time, without disrupting the usual flow of work, than to introduce some large system.

At Deskflow Labs, we build products that the developer actually uses, feels the problems in, and keeps improving. We value not the number of features, but the sense that work has become a little easier the longer you use them.

“Rather than adding more convenient features,
I want to remove the things that stop work.”

POLICY

To build tools you can keep using with confidence.

Processes such as backup, saving, organizing, and verification should run in the background as much as possible — so they never stop your work.

01

Least-privilege permissions

The permissions and information our software uses are limited to what a feature actually requires.

02

Clear about how data is handled

We explain, as clearly as possible, what is stored, what is sent externally, and what is processed only on your device.

03

Designed not to interrupt

We aim for designs where saving, organizing, and backup never interrupt the user’s work.

04

Continuous improvement

Development does not end at release; we keep improving over the long term based on real usage and feedback.

PRODUCTS

What Deskflow Labs builds

We solve problems that arise in desk work — organizing information, interruptions, and repetitive actions — by splitting them into small, purpose-specific products. Rather than bundling everything into one huge service, each is designed as a tool that fits naturally into its task. Today they are grouped into three: tools for work, something for time off, and support for your own activity.

TOOL

Tools for work

Tools that quietly remove what stops the flow of desk work.

Available · v1.1.4

Arrows Lite

Organize the work itself, not just tabs.

A Chrome extension for organizing the growing pile of tabs, in-progress pages, notes, and saved information as a flow of work. Save your working state and pick it back up later without getting lost.

Available

Windows Copy & Paste Mode

The basics, without second-guessing.

An extension that makes copy and paste in development environments like VS Code and Cursor feel closer to ordinary Windows applications. Even users unfamiliar with developer-tool conventions won’t get stuck on the basics.

Available · iPhone

Channel Timeline Viewer

Watch a channel in order, from the beginning.

An iPhone app that sorts a YouTube channel’s uploads from oldest to newest and remembers how far you have watched. It resumes to the second, without pulling you into recommended videos.

FUN

Time off

A small break to stop for a moment and switch gears.

Available · iPhone/iPad

ナンプレIQ (Sudoku IQ)

The difficulty itself is an IQ score.

A sudoku puzzle where your “certified IQ” rises the more you solve. Nine difficulty levels from IQ 80 to IQ 200, freshly generated puzzles that always have a single solution, hints that explain the reasoning, and a daily challenge.

SUPPORT

Support for your activity

Ways to make personal publishing and small businesses easier to keep going.

Available

note フォロバチェッカー (note Followback Checker)

See who follows you back, at a glance.

A Chrome extension that shows whether the people you follow on note follow you back. Results are grouped as mutual, not following back, or unconfirmed, and you tidy up one person at a time by hand. Your note data stays on your device and is never sent anywhere. This is an unofficial tool, not affiliated with note, Inc.

Available · iPhone/Android

Jewelry Sunflower ROOM Partner Club

Keep sharing on Rakuten ROOM and social media, without second-guessing.

A tool that supports manual posting on Rakuten ROOM and social media. It organizes the items that are easy to recommend, simulates estimated rewards, offers post templates, checks disclosure wording, and helps plan a posting calendar. It is a referral-support service run by Jewelry Sunflower, not an official service of Rakuten Group, Inc.
