How did I feel at the beginning?
A moment of joy, an uneasy feeling, something left unsaid. HeldLine: Boundary connects these moments into a journal you can return to as your feelings change.
START WITH A FEW WORDS
Choose an emotion label and add a short note. You do not need a polished diary entry. You can keep journaling entirely in your own words, without AI.
KEEP YOUR FIRST FEELING
Connect later experiences and changes to the original note. A chronological tree lets you revisit how you felt then without replacing it with how you feel now.
TURN CONVERSATIONS INTO REFLECTIONS
Optional AI chat suggests emotion labels and short notes from what you share. You can change the labels yourself. AI interpretations are suggestions, not diagnoses or verdicts.
FIND WORDS FOR A REPLY
When you want to decline or ask for time, create a draft from your situation or conversation. Edit it and copy it when ready.
RETURN AT YOUR OWN PACE
Weekly reflections and optional reminders help you revisit your notes. Check the next reminder and send a test notification in Settings.
Use Boundary to write about relationships, notice what triggers anger, or keep track of feelings and thoughts while learning about cognitive behavioral therapy. It does not provide treatment, diagnosis or professional advice.
FREE JOURNALING AND AI CREDITS
Manual notes, follow-ups, reading your history and on-device weekly reflections are free. There are no ads.
Each AI chat reply, reply draft or analysis uses 1 credit.
Start with 20 credits. From the next day, recover 2 credits per day, up to a recovery balance of 7, even on days you do not open the app.
For more AI use, choose an 8-credit or 50-credit pack, or Standard with 100 credits per month. Purchased top-up credits do not expire. Unused subscription credits do not roll over to the next period. Daily recovery continues with a subscription.
See the purchase screen for local prices and renewal terms. Subscriptions renew automatically and can be managed or cancelled through the App Store. Connection issues or service-wide safeguards may temporarily limit AI availability.
PRIVACY
Your journal and conversations stay on your device. With your consent, AI features send your input and relevant conversation or notes to an external AI service. HeldLine does not collect conversations or keep them on its servers. Information needed to verify purchases and credit balances is managed separately from conversation text. Reporting an AI response sends only the selected response and your reason. See our privacy policy for details.
