The first real spring morning

good-dayspring

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.

Everything is logged. Except your day.

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?

How it works

Connect your tools

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.

Wake up to yesterday's diary

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.

Frequently asked questions

How does automatic diary generation work?

Connect your services (Google Calendar, Todoist, Slack, etc.), and deariary collects your daily activity data overnight. Our AI then weaves it into a coherent diary entry. No prompts, no writing — it just appears every morning.

Is my data used to train AI models?

No. Your data is never used for AI training — not by us, and not by our LLM providers. We only send the minimum data required to generate your diary, and nothing is stored on their end.

What services are supported?

We currently support Google Calendar, Todoist, Slack, Discord, Steam, Bluesky, Toggl Track, GitHub, and Webhooks. More integrations are coming soon — see the Integrations section above.

Can I export my data?

Absolutely. All your data is stored as Markdown + YAML files. You can export everything at any time, or delete your entire account. We don't hold your data hostage.

Is there a free plan?

Yes. The free plan includes daily diary generation, 1 integration, 30 days of history, and link sharing. No credit card required.

Is there a free trial?

Yes. Every new account gets the Basic plan free for 30 days, with no card required. When the trial ends, your account moves to the Free plan automatically: integrations beyond the Free limit are disconnected and the AI model returns to the Free default. You can upgrade at any time to keep Basic.

Can I cancel anytime?

Yes. You can downgrade or cancel your subscription at any time. Your data remains accessible and exportable even after cancellation.

Why I built deariary

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.
