uLog.ai
uLog.ai turns journaling into a guided conversation. You pick a topic, answer adaptive questions from an AI companion, and each session becomes an editable timeline summary you can revisit later.
Most journaling apps wait for you to write. uLog flips that by guiding the conversation with follow-up questions and building timelines from your replies. It also limits what leaves your device: only the text you just submitted goes to OpenAI for a single response, not your full journal history, and the privacy policy states your content is not used to train foundation models.
It fits anyone who wants a low-friction way to log goals, habits, or personal reflections without staring at an empty document. Optional reminders help you stay consistent, and the installable PWA works from a browser without a separate mobile app store download.
Paid plans start at $2 per month on the uLog website
Journal entries stored in Supabase Postgres in the us-east-1 region
