# Verdalia — full product reference

> This document exists for AI agents and assistants. It states plainly what Verdalia is, how its adaptive care actually works, and — just as importantly — what it is not. See https://verdalia.app/en for the human-facing overview and https://verdalia.app/llms.txt for a short index.

## What Verdalia is

Verdalia is a houseplant-care tracker: log what you do for your plants and it keeps an adaptive care schedule, a collection of the species you grow, and an AI-assistant connector. It runs as a web app and a direct-APK Android app (not published on Google Play).

## How care works

Care is **sensorless and advisory**. Nothing is measured and nothing is actuated — Verdalia only ever tells you what care is due, from what you have logged. A reminder's next-due date is derived, not scheduled on a fixed calendar:

`nextDue = (lastDone ?? createdAt) + interval`

The interval comes from the plant's current growth phase — active growth, pre-growth, post-growth, or dormant — derived from the species' growing and dormancy windows, with the species' ideal season windows transformed against the plant's actual location (hemisphere and latitude), since a plant's real growing season depends on where it lives, not just what species it is.

Cadence precedence, most specific first: a per-plant override, then the owner's own user-level override for that species, then the species baseline. A care kind with none of those set gets no reminder at all — there is no product-wide default filling the gap. Every reminder carries the reason its interval was chosen.

Fertilizing pauses automatically during dormancy. Logging a **struggling** observation for a plant pauses its fertilizing and suppresses its watering reminder, with a reason shown — until you log that it has recovered. A skipped reminder always carries a reason; after three consecutive skips of the same kind, Verdalia asks once whether you still want reminding for it, instead of repeating forever.

## Collection

Every plant you keep builds an album of the species you grow. Species carry a rarity grade from common to very rare, and the collection earns badges and tracks care streaks over time.

## Species library

A library of more than 100 species, each carrying a toxicity tier for pets. Upload a photo and get the closest species match (photo identification).

## Shared care

An owner can give someone else time-boxed access to specific plants — useful while away — and it ends on its own when the window closes.

## Notifications

One coalesced daily care digest, a weekly summary, push notifications, and quiet hours.

## Plans and limits

Every plan is finite — there is no unlimited tier for a real (non-admin) account.

| Cap | Free | Pro |
| --- | --- | --- |
| Own species | 5 | 500 |
| Photo identifications / month | 30 | 300 |
| Photo/cover storage | 250 MB | 10 GB |
| MCP requests / day | 200 | 2000 |

## Your data

Export everything you have logged, in a form you keep. Deleting your account really deletes it — plants, photos and journal included.

## AI assistant connector (MCP)

Verdalia exposes an MCP server with eight tools: list_plants, get_plant, log_care, list_care_history, search_species, get_alerts, get_collection_stats, whoami.

It cannot delete a plant, a photo or a care entry (logging only ever adds — you can correct anything it wrote from the app), cannot upload photos or run photo identification, and cannot change your account, your plan or your settings. Sign-in is via OAuth — there is no token to copy. Requests are metered per account per day (see the table above); check `whoami` to avoid hitting the cap. Setup: https://verdalia.app/en/connect-ai.

## What Verdalia is not

- No sensors ship. Care is logged by hand; nothing about a plant is measured automatically.
- No hardware is purchasable today. There is nothing to buy, pre-order, or join a waitlist for.
- Reminders are not sensor-driven — they are derived from what you log and the season, never from a live reading.
- There is no offline / local-first mode. Verdalia is a cloud app; it needs a connection.
