Features
A companion for every step of
your therapy journey
Lucca is there before, during, and after every session — helping you prepare, stay present, and make sense of what matters most.
Walk in feeling ready.
Review what matters, set intentions, and pick up right where you left off.
Session prep
Lucca reviews your recent sessions and suggests topics worth revisiting — so you never draw a blank when the session starts.
Where you left off
See what you discussed last time, what you committed to, and anything you jotted down during the week to bring up next time.
Goal check-in
See your active goals and milestones at a glance — understand where you are and what you might want to bring up today.
Stay present. Lucca remembers.
Lucca quietly captures everything so you can focus on being in the conversation.
One-click recording
Start recording with a single click. Lucca works in the background — no buttons to fiddle with, no interruptions to your flow.
Live transcription
Your session is transcribed automatically as it happens. Speaker identification keeps track of who said what.
Private by design
Audio is processed on your device and never stored. The transcript is encrypted the moment it's created.
Ambient recording that stays out of your way.
Therapy works best when you're fully present. Lucca captures the conversation with a subtle, ambient indicator — no awkward pauses to take notes, no scrambling to remember what was said.
- Subtle recording indicator — a gentle pulse, not a blinking red light
- Audio is transcribed in real-time, then immediately discarded
- Speaker identification distinguishes you from your therapist
Make sense of what just happened.
Lucca turns your conversation into structured insights you can actually use.
Session summary
A clear overview of what was discussed, the topics explored, and the emotional tone of the conversation. Any book, practice, or recommendation your therapist mentioned is kept where you can find it.
Shift detection
Lucca spots the moments that matter — the breakthroughs, the reframes, the new perspectives. We call them Shifts.
Emotional landscape
See the emotional arc of your session visualized — where things felt heavy, where there was lightness, and how the tone shifted over time.
Insights that meet you where you are.
After each session, Lucca generates a structured summary with themes, emotional tone, and detected shifts — all processed locally by AI running on your device.
- Session overview with key topics and emotional tone
- Automatic shift detection highlights meaningful moments
- Searchable, editable transcripts for every session
See the bigger picture emerge.
Patterns, progress, and growth — visible over weeks, months, and beyond.
Patterns across sessions
Lucca connects insights across sessions to surface themes you might not notice on your own — recurring topics, evolving perspectives, emerging strengths.
Weekly reflections
A gentle weekly summary that captures where you've been and where you're heading. Not a report card — just a quiet acknowledgment of the work you're doing.
Chat with Lucca Coming soon
Have a conversation with Lucca anytime. Reflect on a session, explore a feeling, or just think out loud. It's like journaling — but with a companion who knows your story.
Private. Completely.
This isn't a feature. It's a promise. Lucca runs entirely on your Mac and works with the Wi‑Fi off, so no sessions ever leave it.
AI that stays on your Mac
All of Lucca's AI runs on your Mac with local models. Your transcripts never leave it, not even as anonymized snippets.
Encrypted at rest
Every transcript is encrypted on disk with AES-256. Your sessions stay private even if someone else gets to your Mac.
No audio kept
Audio is transcribed as it happens and then discarded. There are no recordings on your Mac, only encrypted text.
No Wi‑Fi needed
Record and reflect with the Wi‑Fi off. There is no Lucca server holding your sessions, so there is nothing for anyone else to reach.
AI that adapts to your device.
Lucca detects your hardware and runs the largest model your Mac can comfortably hold. It starts at 16 GB of memory — and the more your Mac has, the deeper the analysis goes.
- 16 GB: The full Lucca experience — reflections, patterns, chat
- 24 GB: A larger model, for deeper and more nuanced analysis
- 32 GB+: Our largest model, with headroom to spare
The calm presence beside you.
Lucca is free to try. Just you, your therapist, and a companion who's ready to listen.
