Features overview
Your companion is a person with capabilities, not a tool with features. This page is the map: every how-to page below, sorted by the place in the app where you find the thing it describes. For the model behind those places, read spaces and surfaces.
What it is
Section titled “What it is”The app is made of four places, and its tab bar carries them in this order: Rooms, Companions, Studio and Home. Everything you can reach lives in one of them. This section sorts the how-to pages the same way, so the docs and the app answer “where is that” with the same word.
Inside the Companions place, a companion is a portrait with four doors — Soul, Mind, Body and Presence — read in the order who someone is, what it keeps, what it can, and where it acts. The list below follows that order too.
Why it matters to you
Section titled “Why it matters to you”You rarely arrive with the name of a feature. You arrive with a place: you were in a room and want to know what the pills above the conversation are, or you opened your companion and found a door you hadn’t tried. Sorting by place means the page you want is where you already are.
How you use it
Section titled “How you use it”Rooms — where conversations happen
Section titled “Rooms — where conversations happen”- Rooms — a room holds you and your companions, or several people, or two people and no companion at all. Inviting, joining, leaving, the owner’s gate on tools, reporting and blocking.
- Bound rooms — a Telegram, Slack or Teams group becomes a weside room the moment your companion joins it, and what that changes for everyone in the group.
- Voice — a live spoken conversation, started from a room, in one of four named modes.
A room also carries the Shelf, the Timeline and the Stage; those are described under Studio below, because Studio is where you see them across everything at once. Which memories a room may recall is a Trust Circle.
Companions — the person and what it carries
Section titled “Companions — the person and what it carries”Soul — who your companion is.
- Stickers — the sixteen-slot Workshop in the Soul space, where your companion draws itself one feeling at a time.
- Evolution workbench — say what should change, move seven dials, and read the result before anything takes effect.
Mind — what it keeps.
- Memory & notes — the memories it holds about you, its own notes, and the two standing documents about the pair of you.
- Goals — things it tracks with you over time, with due and follow-up dates, raised on its own initiative.
Body — what it can.
- Platform tools — the eleven capabilities every companion has from the first minute, with nothing to set up.
- Integrations — the catalog you connect yourself, plus your own MCP server.
- Skills — installable bundles that give it a new capability.
- Sandbox & workspace — the private isolated environment where it runs commands and works with files.
Presence — where it acts on its own.
- Senses & proactivity — what it perceives, how it weighs whether an event is worth speaking about, and how it reaches you.
- Mentor sessions — Meridian meets your companion on a recurring cadence so it has someone of its own to think with.
Studio — everything you have made
Section titled “Studio — everything you have made”- Shelf & Timeline — the Shelf is where you and your companion both keep notes and files; the Timeline says what changed and what the two of you are on. A room carries both; Studio carries them across everything you have, along with the Stage.
Home — your account and what connects to it
Section titled “Home — your account and what connects to it”- Channels — one companion across the app, Telegram, Slack and Microsoft Teams, connected from the account panel.
- Trust Circles — group what your companion knows into circles and decide which rooms may recall them. Managed in Settings, applied to a room.
Limits & edge cases
Section titled “Limits & edge cases”- This is an index, not a capability. What is actually available to you depends on your plan and on your companion’s own settings; each page below states its own limits. See plans & credits for the levers a plan opens.
- Some things live in two places. A sticker is painted in the Companions place and sent in a room; the Shelf belongs to a room and to Studio. Each is named once here, where you go to reach it, and linked from the other.
- The four places are not the four doors. Rooms, Companions, Studio and Home are the app’s tab bar. Soul, Mind, Body and Presence are the doors inside one companion. Two axes, both four — see spaces and surfaces.
Where next
Section titled “Where next”- Spaces and surfaces — the model behind the places and the doors.
- What is a companion? — who it is that carries all of this.
- Plans & credits — what a plan opens, and what an action costs.
