No streaks. No optimizing.
Tell your AI about your day while the rain comes down. What you talk about becomes today's entry.
Rainku opens on rain, and your AI may speak first. Answer in the words you'd actually use. As you talk, the parts worth keeping are added to today's entry.
What you say
The entry you get back
A long day with nothing wrong in it, which is the kind that's hardest to name. What I ran out of this week wasn't energy — it was words. I spent five days explaining things to other people, and by Friday there was nothing left for the ones I actually wanted to talk to.
What I want from next week is small: one conversation where I'm not the one making it make sense.
Composed from the conversation, not from a template. Sign in to write your first entry with the free plan.
General chat tools can discuss almost anything, but they are not necessarily designed for long-term journaling. AI journals place more emphasis on continuity, revisiting past entries, and organizing your thoughts. Rainku also adds your conversations to your journal.
A journal is some of your most personal writing. Here is where it goes.
With the same Worldku account, and depending on your memory settings, your AI can recall what you talked about in Rainku and in other Worldku apps. Your journal is not part of that: to show your AI an entry, tap Share on the entry to send it to the chat.
Rainku runs in any browser. Nothing to install on Mac, Windows, or Linux. The same page works on phone and tablet. Available in six languages: English, 简体中文, 日本語, 한국어, ไทย and Bahasa Indonesia.
Rainku is free by default. The free plan comes with a weekly allowance. Pro gives you a larger weekly allowance, and Max gives you the largest. Both include access to backgrounds marked PRO. You can pay monthly or yearly for either plan; paying yearly costs less.
