Frond

Frond is a digital herbarium for anyone who collects plants — botanists, foragers, gardeners, hikers, and the merely curious.

Record a specimen the way you would in a field notebook: photograph it, note where and when you found it, describe the leaf shape, the habitat, the smell of the crushed stem. Frond keeps each entry as a proper record rather than a photo buried in your camera roll.

WHAT YOU CAN DO

- Build a specimen catalog with photos, dates, locations, and detailed field notes
- Get identification help from AI — describe or photograph a specimen and receive a considered answer, not a one-word guess
- Search and browse your collection as it grows
- Keep everything on your device, in your hands

BRING YOUR OWN KEY

Frond uses your own Google Gemini API key for identification. You paste the key once; it stays on your device and is never sent anywhere except Google's API. No account, no sign-up, no subscription, no server of ours between you and your data. Free tier keys work fine.

You can also add specimens entirely by hand and skip the AI altogether.

ONE-TIME PURCHASE

Frond is free to try. A single unlock removes the limits — pay once, keep it. No subscription, no ads, no upsells.

FOR THE FIELD

Built for people who actually go outside: a clean, legible interface that works in bright sun, records that make sense six months later, and no distractions between you and the plant in front of you.
