Chronock combines scheduling and cross-calendar sync in one workspace. It checks availability across connected Google and Outlook calendars, turns open time into a booking page, and syncs events between work, personal, and project calendars to prevent double bookings. Guests see only bookable times, while you can review every connected event in one Integrated Calendar. Start free with no credit card.
I’m Takahiro Ikeuchi, a solo product engineer from Tokyo 🗼 and the maker of Chronock.
I started building Chronock after repeatedly running into the same problem in two different roles.
As a CTO, I spent a lot of time coordinating recruiting interviews. As a coach, I also needed to schedule meetings with people outside my organization. Native calendar features often felt too limited, while broader scheduling suites could be difficult to justify on price. At the same time, keeping my work, personal, and project calendars aligned often meant paying for and managing another tool.
That led me to a simple idea: scheduling and calendar sync are not really separate problems. They are both about keeping your availability trustworthy.
Chronock brings them together in one workspace:
- Create booking pages that check your Google and Outlook calendars
- Sync events between work, personal, and project calendars
- Review connected events in one Integrated Calendar
- Find and share open-time candidates when a booking link is not the right fit
As a Japanese maker, I also wanted multilingual support—including Japanese—to be part of the product from the beginning, rather than an afterthought.
I wanted to create a focused and accessible utility without treating quality as optional.
I’ve spent more than 10 years working as a full-stack engineer and now describe myself as a product engineer. I’m interested in the entire process, from UI design and frontend development to backend systems and cloud infrastructure.
Chronock is built AI-natively. I use coding agents such as Codex and Claude Code throughout development, but I don’t equate AI-native development with handing off engineering judgment. Architecture, design, security, testing, and the final quality bar still require deliberate care.
For me, the real value of AI is not only speed. It helps a very small team avoid unnecessary compromises and stay close to the people using the product.
Chronock is still at an early stage, and this launch is an opportunity to learn. There’s a free plan, and no credit card is required.
I’d especially love your feedback:
- What is the hardest part of managing multiple calendars today?
- Do you prefer sharing a booking link or proposing a few specific times?
- Is anything about Chronock’s setup or positioning unclear?
Thank you for taking a look. I’ll be here throughout the launch and would be happy to answer any questions.

Who hunted Chronock?
Chronock was hunted by Takahiro Ikeuchi. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
