## What is AI Mushroom Field Notes?

This app does not judge whether a mushroom is edible. Never use it to decide whether a mushroom is safe to put in your mouth.

AI Mushroom Field Notes is for observing, collecting and keeping the mushrooms you meet on a forest walk, a camping trip, or an ordinary stroll. It is not a tool for naming things. What a photo can show is the nearest family or genus, and the app will not declare a species.

[The nearest relatives, from a photo]
- From a photo you take, or one from your album, the AI inside your phone suggests family and genus candidates, such as "close to Amanitaceae / Amanita"
- Only two ways of saying it: "close" and "possibly close". No percentages
- When it does not know, it says so honestly: "could not find a close relative". It will not invent an answer

[Keep the day you met it]
- Save the photo and the date as an observation note
- A candidate can be attached to the note with a tap, but it is never treated as a confirmed species
- Location is not used. Your places are never recorded without you

[A field guide you can simply read]
- 15 families and 18 genera, written from scratch in Japanese and English
- Appearance / season / where you may meet it / clues for telling them apart / how it lives / a small surprising fact / a word from Sakura
- Every page names its sources (ja/en Wikipedia, GBIF Backbone Taxonomy)
- The guide can be read without taking any photo

[About look-alikes]
- Mushrooms that look alike in colour and shape can belong to completely different groups
- Even specialists will not declare a species from a single photo
- Neither will this app. That is why it is built not to answer too much

[Made to be safe to use]
- The judgement runs inside your phone only. Photos and notes are never sent anywhere
- No account needed
- No ads
- The guide and your notes are free, and stay free

[One-time Premium]
- Not a subscription. One payment opens the photography tips and observation hints for every group
- On a new phone, use "Restore purchase"
