Read Aloud now highlights the paragraph it is reading, and a better memory brings the journal entries that matter into your chats.
Talk through what's on your mind with an AI companion that actually remembers your story. Onsen is a free mental wellness app for chat, journaling, therapy-inspired experiences, and self-awareness, all in a private, non-judgmental space available 24/7.
"This app has done more for me in 3 days than my therapist has done in months."
54% of users felt happier within 3 months, measured by the Oxford Happiness Questionnaire.

Onsen is a wellness companion designed to support self-reflection, emotional well-being, and mindfulness. It does not provide medical advice, diagnoses, or treatment. The content within the app is for informational and self-improvement purposes only and should not be considered a substitute for professional medical or mental health advice. If you have any health concerns, please consult a qualified healthcare professional.
A new Read Aloud player follows along as it reads, and a better memory lets your chats draw on the journal entries that matter to what you are saying. Pictures, check-ins and several experiences get smarter too.
- New Read Aloud player. Tap or drag the bar to jump to any point, see how long the reading is, pick a speed from 0.75x to 1.5x, and skip back or forward 10 seconds, even while the voice is still loading or paused. Every control works with VoiceOver.
- Follow along. While Onsen reads a reply or a journal entry aloud, the paragraph being read is highlighted and kept on screen. Tap any paragraph or list item to hear it from there. Meditations Onsen speaks show their progress from the start.
- Better memory. When you chat, Onsen searches your journal for the entries that match what you are saying, puts your recent ones first, and draws on several different entries instead of many pieces of one. The gratitude letter uses the same search, and brings up fewer entries it has already shown you.
- Full chats. As a chat nears its limit, a note shows how many messages are left. When it is full, a card says so with a Start a new chat button, and a help sheet explains how to carry on: add the chat to your journal, then start a new one. Onsen remembers your journal, so nothing is lost.
- Messages that fail. If a message does not send, the chat shows "That message didn't send" with a Retry button, and it stays there when you come back to the chat. If a welcome cannot load, you can retry or leave.
- Easier reading. Replies and entries have more space around headings, lists, quotes, code and tables, and the last line of a paragraph in a long page no longer goes missing.
- Pets in your pictures. Journal pictures now draw your pets as the right animal, with their breed and colour when you have written about them, and pictures start sooner.
- Check-ins. After a check-in, Onsen's take is a short card. Each point ties to your journal, and it compares with your previous check-in.
- Experiences. Clear Negative Thoughts has been rewritten, with replies laid out like a chat. The gratitude letter offers fresh categories each time and keeps its quotes short. Mood check-in replies come in short paragraphs, with your name and your moods in bold. Creating your avatar keeps more of the details you describe, and the voice step for a custom personality lists the HD voices first.
- A better balanced safety system. Onsen still responds to real risk, with emergency help when someone is in danger, and no longer brings up crisis support in conversations that don't need it. If the safety check flags one of your messages, the chat now says so, with a Show my message button, and you can edit the message and send it again.
- More reliable. An entry's title and tags get a second try when the first fails, a reply that stalls is cut and tried again, and Read Aloud tries again when its voice is slow to start.
- Fixes: a voice preview now plays the voice you picked, an experience opened from a notification can be saved to your journal, a message sent as the connection drops is no longer sent twice, your answers in check-ins and experiences go to the right place, Did it today works on the day a practice is made, and What's New no longer appears for new accounts. A shared entry opened before installing Onsen now opens after you sign up.
