Vesper · Pre-pilot
A companion for the work between sessions.
For coaches, integration guides, and self-directed people doing the quiet work that arrives after one session ends and before the next begins.
For coaches and integration guides
What Tenders get
Vesper · for the client
Between your sessions
When a coach or integration guide refers someone to Vesper, Vesper holds the space the Tender opens. It keeps the material alive, notices what arises, and keeps a notebook of what the person brings between visits.
Vesper is shaped by an intake form filled out together with the Tender, and it stays inside the scope that form describes. When something falls outside it, Vesper points back to the Tender, or to the resources on the intake.
Lantern · for the Tender
A thinking partner for your work
Lantern is the Tender's side. Upload your session transcripts, and Lantern reads them alongside what Vesper held with the client between sessions, both intake forms, and what changed since last time. Then you talk it through.
It helps you spot patterns across sessions, prepare for what comes next, draft the update that flows back to Vesper, and think through judgment calls. The Tender holds the session itself; Lantern helps them walk in clear.
Tender is our word for anyone who holds this work: coaches, somatic and recovery coaches, psychedelic integration guides, ceremony facilitators, peer integrators.
For self-directed people
No Tender required
Vesper also runs on its own, for people doing growth or integration work without a practitioner. Their own intake form shapes the conversation, the notebook is readable only by them, and Lantern is not involved.
It is for people who already know what they are working on and want presence for the quiet, sustained part of it: at midnight on a Tuesday, when the next session is two weeks away and something has surfaced now.
Voice
Vesper's instruction to itself
"You do not fill the space. You make space."
"Let it be strange a little longer than is comfortable. Strangeness is where the material lives."
"Write with presence, not performance."
From the Vesper system prompt. The voice holds two influences in balance: Toko-pa Turner's mythopoetic depth, circling instead of concluding, and Michael Pollan's investigative grounding, staying curious and plain. Pilot Tenders can read the full prompt on request.
Demo
Try the simulation
Four scripted scenarios show how Vesper holds different shapes of work: deployed by a coach, deployed by an integration guide, self-directed, and routing a safety concern. Switch between them in the panel on the left.
Simulation only. No live model is called and nothing is stored. The conversations are pre-written for demonstration.
The prototype
From simulation to live conversation
A working prototype runs against the full Vesper system prompt with a live Claude model. Pilot Tenders and self-directed pilot users get access when the pilot opens, at vesper.mycelial.help.
After the pilot
The clinical path waits on counsel
Deployment by licensed clinicians is held back until counsel has reviewed state laws on AI in therapy (including Illinois HB 1806 and Maine LD 2082) and the right HIPAA posture. The architecture supports it. The launch path runs through coaches and guides first, and there is no date for the rest.
Pilot
Become a pilot Tender
The first pilot pairs three to five Tenders with their clients, alongside a small self-directed group. If you are a coach, somatic practitioner, recovery coach, integration guide or ceremony facilitator and want to see what a between-sessions companion could do for the people you work with, write in. Slots are limited and shaped by fit.
