Capturing your thought

Done
On device
167 hours a week your
therapist can't see
0 seconds to capture
a thought before it's gone
100% your voice never leaves your device
complete privacy, by design

The thoughts that matter most never make it to the room.

In behavioral health, so much lives in the space between visits — the quiet details, the moments you try to remember but can't fully reconstruct. The unfiltered weight of a 2am realization. The post-argument clarity that's gone by Friday.

Therapy is powerful. But it runs on a 50-minute sample of a 10,080-minute week. Lisner captures the other 10,030 — not by tracking you, but by giving your own words a place to land.

"I cancelled again today. Third time with the same friend. I keep telling myself I'll feel more like it next week and I'm starting to think next week is just a story I tell myself."

Captured in 11 seconds. On your device. Waiting for when you're ready.

How it works

Speak, don't type

One tap. Say what's on your mind. Your words stay private — nothing is ever sent to a server without your choice.

Patterns, not homework

Your thoughts are organized automatically — by theme, emotional signal, what keeps returning. No categories. No homework.

Speak any language

Lisner understands you in the language your thoughts actually arrive in. No translation. No switching. No cognitive overhead.

Yours until you decide

Everything stays private on your device by default. You choose what to share, with whom, and you can change your mind at any moment.

Not a chatbot.
Not a tracker.
Not a monitor.
A listener.

Privacy isn't a feature. It's the foundation — because a tool for mental health that isn't radically private isn't a tool.

Most AI wellness apps send your words to the cloud to be processed, stored, and used to train models. Lisner doesn't. Your voice is transcribed and understood on your device — nothing leaves it until you choose to share. That's a difference of architecture, not policy.

Your voice
Raw audio,
captured locally
On your device
Transcribed & secured
On-device processing.
Stored locally or in your private iCloud.
The cloud
Lisner servers never receive your voice recordings. Text is only transmitted when you explicitly share with your therapist.

No passive collection. Lisner only captures what you actively choose to record. Nothing runs in the background — ever.

Your voice never leaves your device. Transcription happens completely offline. Your text transcripts are stored locally and in your private iCloud backup—we have zero access unless you explicitly share with a care provider.

You control what's shared. If you ever want to share a thought with someone you trust — it's your choice. And you can change your mind instantly.

Delete is permanent. When you delete a thought, it is immediately deleted from your device and synced out of your private iCloud. We keep no backups.

Your progress travels with you.

Switching therapists shouldn't mean starting over. With Lisner, your thought history — themes, patterns, insights — moves with you. It's always your choice.

Patient-owned data

Your thought history lives on your device. It belongs to you — not your therapist, not us, not a health system.

Seamless therapist switch

Disconnect from one therapist, connect to another. Your full history moves with you.

No vendor lock-in

Your progress isn't trapped in someone else's system. Export your data. Switch providers. Your mental health journey is yours to keep.

Let your therapist know.

One tap sends them a note with everything they need to get started.

Built with the clinicians who know this gap best.

Lisner is being shaped in active collaboration with licensed clinicians across ADHD, anxiety, depression, trauma, and bipolar specialties. Early design partners have direct input on what the product becomes — before it reaches the world.

"I'm exploring how technology can thoughtfully support the therapeutic process while keeping the therapeutic relationship at the center of the work. Lisner helps bridge the gap between sessions — without getting in the way of it."

The things people ask first.

Is Lisner really private?
Yes — by design, not by promise. Your voice is recorded and transcribed on your phone. Nothing is sent to a server, and nothing is shared with anyone, until you explicitly choose to. There's no background tracking and no passive data collection.
Is Lisner an AI chatbot that talks back?
No. Lisner doesn't give advice, diagnose, or hold a conversation. It's a private place for your own words — it captures what you say and helps you see the patterns over time. It's a listener, not a chatbot.
What does it cost?
The app is free to download and use. There's no subscription and nothing to cancel.
Is Lisner HIPAA compliant?
Yes. Lisner is built on HIPAA-compliant infrastructure, with compliance verified by Accountable HQ, and a BAA is available for clinical partners.
Do I need a therapist to use it?
No. Many people use Lisner just for themselves. If you do see a therapist, you can choose to share what you've captured — with a single toggle you control, and can switch off at any time.
Can I delete my data?
Anytime, completely. Your entries live on your device and are yours to delete. If you'd shared with a therapist and then disconnect, your shared data is removed — a clean break, always. Questions? privacy@lisner.ai.
