About this app

Your journal shouldn't feel like homework.
Ostra is the voice diary that writes itself, and the AI journal that turns
how you talk into something worth reading. Just speak about your day, a
memory, or a feeling, and watch your words become a real diary entry in
seconds.

HOW IT WORKS
Tap the mic and speak freely. No prompts, no templates.
Choose your mode: clean transcription or AI-crafted narrative.
Your entry appears polished, titled, and organized by day.
Journaling in seconds, not minutes.

AI STORY MODE
Your voice memos become real writing. Ostra captures your tone and context, turning scattered thoughts into eloquent prose that sounds like you on your best day.

CLEAN TRANSCRIPTION
Prefer accuracy? Get word-for-word transcripts, great for quick notes,
meeting recaps, or stream-of-consciousness dumps.
YOUR VOICE, YOUR STYLE
Choose a narrative personality: reflective, witty, poetic, or straight to
the point. Ostra adapts its writing to match how you naturally express
yourself.

MOOD & MEMORIES
Every entry captures how you felt, not just what happened. Track your mood
over time, revisit gratitude moments, and use Ostra as a daily diary for
mental wellness and reflection.

DAILY CHRONICLES
Every day gets its own title and summary. Browse your life like chapters in
a book.

PRIVATE BY DEFAULT
Audio stays on your device. Text is encrypted. We can't read your diary
entries, and we don't want to.

FLEXIBLE PLANS
• Wanderer (Free): 30 min/month, transcription + 3 free story entries
• Dreamer ($4.99/month): 5 hrs/month, unlimited Story Mode

Need more minutes? Buy ink credit packs that never expire.
Your story deserves more than bullet points. Start speaking.
