The aisle test
Reading a label isn't a diagnosis
Tiny print. A language you don't fully read. An ingredient name you're not sure is a synonym for wheat or not. For celiac disease and lactose intolerance, guessing wrong isn't a bad meal — it's real symptoms. Knowbite isn't a medical device — it's built by someone who lives with this, for people who need a straight answer, fast.

Where the data comes from
Backed by the world's largest open food database
Knowbite runs on Open Food Facts — 4 million+ products, kept current by a global community, not a single company's catalog.
Scan something we don't have yet? Report it in one tap and it goes on the list for future coverage.
Where we're live
Estonia, Latvia, Lithuania — Poland, Czechia and Slovakia next
Knowbite works wherever the underlying product database has coverage. We're focused on the Baltics first, with Poland, Czechia and Slovakia rolling out right after.
Questions
Is Knowbite free to try?
Yes. 2 free scans without an account, and 2 more after you sign up — no card required.
What does Knowbite check for?
Gluten and lactose, from barcode and ingredient data. It’s informational — it doesn’t replace reading the label yourself or checking with a doctor.
What if a product isn't in the database?
You’ll see a clear "not found" screen and can report it in one tap, so it gets added for next time.
What does "can’t verify" mean?
Sometimes there isn’t enough data to check an allergen with confidence. Rather than guess, Knowbite says so honestly instead of showing a false safe or unsafe.
