If you already use PlantNet, you know its strengths: it's completely free, has no ads, and is backed by a French research consortium (Cirad, Inria, IRD, and INRAE). It identifies close to 60,000 species from a photo of a leaf, flower, bark, or fruit, and every submission feeds real citizen-science databases. For putting a name to a wildflower on a hike, little beats it.
The reason people go looking for alternatives to PlantNet is almost always the same: PlantNet stops at the name. It has no care instructions, no watering reminders, no frost alerts, and no way to ask "okay, now what?" That's not a flaw — it was built as a botanical identification tool, not a gardening assistant. But if you want the care half of the job, you need a different app. Here are the honest options for 2026.
Quick comparison
| App | Best for | Care guidance? | Price | Platforms |
|---|---|---|---|---|
| PlantNet | Free, science-grade ID of wild & native plants | No — ID only | Free, no ads | iOS, Android, Web |
| Growli | ID plus care, diagnosis & reminders | Yes — full care + chat | Free | iOS, Android |
| PictureThis | Largest catalogue for ornamentals & houseplants | Yes — static care tips | Paid (~$30/yr) | iOS, Android |
| Seek (iNaturalist) | Free, private, gamified ID for families | No — ID only | Free | iOS, Android |
| Plantum | Budget all-rounder: ID + diagnosis + reminders | Yes — care assistant | Freemium (paid) | iOS, Android |
No single app wins every column. PlantNet and Seek are the free ID purists; Growli, PictureThis, and Plantum add the care layer PlantNet leaves out. Below is where each one actually fits.
Growli — the care upgrade after ID
Growli is an AI gardening assistant that does what PlantNet deliberately doesn't: it stays with you after the photo. Snap a picture to identify a plant or diagnose a sick leaf, then keep asking questions in plain English — "why are the tips browning?", "is this safe around my cat?" — and get answers back in conversation rather than a static page.
Pros:
- Photo ID, leaf-symptom diagnosis, and a conversational chat in one app.
- Care reminders, frost alerts, and a daily plan tailored to your plants and location.
- UK-localized using RHS guidance, not just US defaults — genuinely useful for en-GB gardeners.
- Built-in ASPCA pet-safety data, so you can check cat and dog toxicity before buying.
- A library of roughly 11,700 species, 4.6 stars on the App Store, and 7,000+ growers.
- Free on iOS and Android.
Cons:
- It's care-first, so if you only ever want to name wild plants and never grow anything, PlantNet alone is lighter.
- Younger than PlantNet, so its wild-flora dataset skews toward cultivated and houseplants rather than rare natives.
Who it's for: anyone who identifies a plant and then wants to keep it healthy. Growli is the natural next step from a pure identifier — see our plant care app buyer's guide for the full feature checklist.
PictureThis — the biggest catalogue, but paid
PictureThis is the market leader for cultivated houseplants and garden ornamentals, with one of the largest trained catalogues and a very polished interface. It adds care tips and a paid disease-ID feature, so it covers more than PlantNet — but the useful parts sit behind a subscription of roughly $30 USD / £25 GBP per year after a free trial.
Pros: excellent on ornamentals and hybrids; fast, beginner-friendly UI; care tips per species.
Cons: aggressive paywall and frequent auto-renewal complaints; care advice is a static FAQ, not a dialog; weaker than PlantNet on wild species. For a deeper look, read our head-to-head PictureThis vs PlantNet comparison.
Who it's for: houseplant collectors who want the broadest catalogue and don't mind paying.
Seek by iNaturalist — the closest free match
If what you love about PlantNet is that it's free and privacy-friendly, Seek is the nearest alternative. Made by iNaturalist and supported by the California Academy of Sciences and the National Geographic Society, Seek identifies roughly 80,000 species of plants, animals, and fungi. It requires no account and collects no personal data by default, and it gamifies identification with badges — great for kids and families.
Pros: completely free, no ads, no sign-up, strongly private; identifies wildlife as well as plants; educational and fun.
Cons: ID-only, like PlantNet — no care instructions, reminders, or diagnosis; deliberately points you to iNaturalist for anything deeper.
Who it's for: naturalists, teachers, and families who want free, private identification and don't need care features.
Plantum — budget all-rounder
Plantum bundles identification, one-shot diagnosis, and a care assistant (watering reminders, plant logging, a light meter) into one app. It identifies over 33,000 species. There's a free tier with unlimited IDs but only a single health diagnosis; the full care features are subscription-based, typically around $29.99 per year, with frequent promotional and lifetime deals.
Pros: more care features than PlantNet at a lower everyday price than PictureThis; light meter is a nice touch.
Cons: best features are gated; smaller catalogue than PictureThis; care depth is lighter than a dedicated assistant. See where it lands in our best plant identifier app roundup.
Who it's for: budget-minded growers who want ID and basic care in one place.
How to choose
A short, honest decision rule:
- "I just want free, science-grade ID of wild plants." → Stay on PlantNet, or add Seek as a second opinion.
- "I want to identify a plant and keep it healthy." → Growli — it adds the care, diagnosis, and reminders PlantNet skips, and it's free.
- "I mostly photograph houseplants and want the biggest catalogue." → PictureThis, if you'll pay.
- "I want care features on a budget." → Plantum.
- "I need pet-safety checks or UK/RHS guidance." → Growli.
Many growers keep two apps: a free identifier like PlantNet or Seek for wild plants, and a care-first app for the plants they actually own. For the fundamentals once you've made your pick, start with our plant care hub.

Frequently asked questions
Is PlantNet free?
Yes. PlantNet is completely free, ad-free, and has no paywall or in-app purchases. It's run as a citizen-science project by a French research consortium — Cirad, Inria, IRD, and INRAE — and funded through institutional and research-grant support rather than subscriptions. Every identification you submit helps train its model and can feed public biodiversity databases. There is no premium tier to unlock.
Does PlantNet tell you how to care for plants?
No. PlantNet is an identification tool only — it names the plant from a photo but does not provide care instructions, watering schedules, reminders, or symptom diagnosis. That's by design; it was built as a botanical ID app, not a gardening assistant. If you want care guidance after identification, an app like Growli or PictureThis adds that layer, while Growli's is conversational and free.
What's better than PlantNet?
It depends on the job. For pure free identification of wild plants, nothing is meaningfully better — PlantNet is best in class, with Seek by iNaturalist a close free alternative. But if you want the step PlantNet skips — care, diagnosis, reminders, and pet-safety checks — Growli is the strongest upgrade, since it pairs photo ID with conversational care guidance and is also free.
Is there a free alternative to PlantNet with care features?
Yes. Growli is free on iOS and Android and combines photo identification and leaf diagnosis with care reminders, frost alerts, a daily plan, and conversational follow-up questions. It also includes ASPCA pet-safety data and UK-localized RHS guidance. Unlike PlantNet, which stops at the name, Growli covers the ongoing care of plants you already own — without a paywall on the core features.
How accurate is PlantNet compared to other apps?
PlantNet is highly accurate on wild flowers, weeds, trees, and native species, because its dataset is built from outdoor citizen-science observations and it lets you photograph multiple organs — leaf, flower, bark, or fruit — to narrow the result. It's weaker on cultivated houseplants and hybrids, where catalogue-heavy apps like PictureThis often do better. It shows ranked candidates with confidence scores rather than a single guess.
Which PlantNet alternative is best for houseplants?
For naming houseplants, PictureThis has the largest cultivated-plant catalogue, though it's paid. For actually keeping houseplants alive — watering reminders, diagnosis of yellowing or browning leaves, and pet-safety checks — Growli is the better fit and is free. PlantNet itself is weaker on cultivated indoor plants than on wild species, so a care-focused app is usually the better indoor companion.
