Datify VS Caviste

Caviste's answer:

Caviste turns a photo into a stocked cellar, then tells you when to open each bottle.

• The label scan reads the label itself, with no catalogue to match against: estate, cuvée, appellation, region, vintage and grape varieties come back from the photo. When the label keeps the grapes to itself, they are inferred from the appellation.
• The drinking window is computed on five levels: named estate, appellation (Champagne cuvée tier included), region, grape, then corrected by the vintage. It can be rewritten bottle by bottle.
• A cellar map drawn as your racks really are, so every bottle has a slot you can find again.
• A sommelier that only suggests what you own: describe tonight's menu in one sentence and it picks up to three bottles from your own cellar, explains each pairing and tells you which rack to look in.
• Free CSV import and export, both ways, so the cellar is never locked in.

Caviste's answer:

• No catalogue dependency. The scan reads the label, so a small grower or an old vintage does not have to exist in someone's database to be recognised.
• A drinking window you can audit and correct. It is computed rather than looked up, and the app says which level it came from. When someone rewrites a window, that correction is measured against the table, so the table improves from use.
• Your data leaves as easily as it arrives. CSV export is free, there are no ads and nothing is resold.

Pricing is 2.99 EUR a month or 24.99 EUR a year, and the free tier keeps 30 bottles for as long as the account exists.

Caviste's answer:

Private wine owners with roughly 30 to 500 bottles who have lost track of what they have and when to drink it.

Not professionals: Caviste manages a personal cellar, not a winery or a merchant's stock. In practice that is an enthusiast who buys a few cases a year, keeps them for years, and wants to stop opening bottles too early or too late.
