167 hours of you, finally heard.

Your therapist sees you for 50 minutes a week. Lisner preserves the other 167.
Because sometimes you just need someone to listen. That's it.

You're on the list. We'll reach out quietly. ✦

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

The unfiltered weight of a 2am moment. The post-argument clarity that's gone by Friday. Reconstructed from memory, under observation, in a cognitive state nothing like when the insight occurred.

Therapy is powerful. But it runs on a 50-minute sample of a 10,080-minute week. Lisner captures the other 9,960 — 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."

How it works

Speak, don't type

One tap. Say what's on your mind. Lisner transcribes in seconds — on your device, without ever sending audio to a server.

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 tracker.
Not a monitor.
A listener.

Privacy isn't a feature we added after the fact. It's the constraint we designed around from day one — because a tool for mental health that isn't radically private isn't a tool. It's a vulnerability.

Your voice
Raw audio,
captured locally
On your device
Transcribed & secured
On-device AI only.
Nothing leaves this boundary.
The cloud
Never receives your
voice or raw thoughts

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

Audio never leaves your device. Transcription happens on your phone using on-device AI. No server ever hears your voice.

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's gone — from your device, from everywhere. No soft deletes. No cloud backup we're keeping.

Built in collaboration with the people who know this gap best.
