Fully automated diary
Connect your tools, and deariary turns your daily activity into a personal diary. Every morning, automatically.
Woke up to actual sunshine for the first time in weeks. 14°C, clear sky, a Saturday that already felt like a gift. I went for a run along the river and the cherry blossoms are starting to open. Just a handful of petals, but enough to make me stop and take a few photos.
Met Mika for lunch at the new Thai place. We'd been meaning to go for a month, and it didn't disappoint. I'll definitely be back. Shared a photo on Bluesky afterward, which got a few likes. Small joys.
Your activity is scattered across a dozen apps. A personal diary would tie it all together, but who has time to write one every day?
Meetings in Calendar, messages in Slack, code in GitHub. The pieces exist. No one is putting them together.
Keeping a diary has no ROI. Blogs build careers, tweets build audiences. A private diary? You never start.
You tried. The streak died in a week. Writing every day is a second job.
Your fullest days vanish first. Too busy living to write it down. The best memories have the shortest shelf life.
What if you never had to write at all?
Link Google Calendar, Slack, GitHub, and more. Each service captures its piece of your day: meetings, conversations, commits, game sessions. Together, they form the full picture.
Overnight, deariary collects your activity and AI weaves it into a diary. Your Calendar meetings, Slack conversations, and coding activity become one story, not scattered fragments.
Share any entry via link. Or do nothing at all. Just let it accumulate. One day you'll look back and find years of your life waiting there, like a Google Maps timeline you never had to maintain.
— No writing required. No prompts. No habits to build.
You already use apps that track what you watch, listen to, play, and share. deariary turns that activity into a diary, automatically. Pick the use case that fits your life and see how it works.
More coming soon: Fitness diary, reading diary, and more.
No single app knows your whole day. deariary combines them all into one diary. The more you connect, the richer the story becomes.
Coming Soon: Notion ·Strava ·Trello ·GitLab ·Mastodon
Set it up once and never think about it again. No habit to build, no streak to maintain. Your diary just appears every morning, like a gift from yesterday.
Weekly and monthly summaries surface patterns you'd never notice day-to-day. Time Jump lets you revisit any day from 1 month, 1 year, or further ago.
Share any entry via link with an expiration of 24 hours, 7 days, 30 days, or permanent. Revoke anytime. Your diary, your rules. See a real profile →
Your data is stored as Markdown + YAML. Export everything, delete everything, leave anytime. We don't hold your data hostage.
deariary generates your diary in three distinct formats. Pick the one that fits you.

The best Saturdays aren't the most exciting ones. They're the ones where nothing feels rushed.
The afternoon was all errands: dentist (all clear), groceries, and an ambitious attempt at homemade pasta. It actually turned out okay. I might be getting better at this cooking thing.
Dinner with Sho and Aya at the Italian place near the station. We talked about summer plans and whether anyone actually finishes the books they buy. (Nobody does.) Ended the night with Stardew Valley on Discord. Sho and I finally completed the Community Center. A satisfying end to a satisfying day.
5 km along the river. 14°C, clear. First real spring morning. Cherry blossoms opening. 3 photos. Picked up dry cleaning. Knocked out 2 Todoist tasks before 9.
New Thai place. Really good, will go back. Posted a lunch photo on Bluesky (8 likes). Caught up on Slack, replied to 4 threads.
Dentist all clear. Made pasta from scratch for the first time. Verdict: not bad, actually.
Italian place with Sho and Aya. Home by 22:00. Stardew Valley on Discord with Sho. Finally finished the Community Center.

I had wanted this for years: a way to turn daily data into a written record automatically. Nearly a decade ago, I was already building small tools around the GitHub Events API to generate monthly summaries of what I had done.
They worked, but they never lasted. Every version still depended on manual updates, and eventually I would stop. I kept running into the same wall: building something is easy compared with building something that keeps working with your real life.
Then I built a private LLM-powered prototype, and it genuinely moved me. For the first time, the output felt alive rather than mechanical. With my background in ETL and data integration, the architecture for deariary clicked almost immediately.
The space is still early, but the timing is right. LLMs make iteration fast enough to ship and improve in real time. After years as a full-stack engineer in startups, I wanted to turn what I know into something genuinely useful. deariary is that attempt: a diary that exists without asking you to become a disciplined diarist.
