Get the self-hosted versionAI that earns its place
Less data entry. More useful context.
Use AI where it saves time or helps you make a decision. Every core journal feature keeps working when AI is turned off.
Scan the bag, skip the typing
Photograph a coffee bag and turn its label into structured bean details, ready to review and save.
Research the missing context
Fill in beans, roasters, and machine settings from relevant sources instead of hunting them down yourself.
Dial in the next brew
Compare a brew with your matching history and get one evidence-grounded adjustment to try next.
From photo to coffee record
Start with a bag, not an empty form.
Scan the label, review the extracted origin, process, roast, and tasting notes, then keep everything linked to every brew you make.
Optional and server-side. Self-host your journal, choose an OpenAI-compatible endpoint, and inspect the raw inputs and responses behind every request.
AI recommendations
Make the next brew a controlled experiment.
Ask for an opinion on a draft or a logged brew. Roastbook compares the same bean, method, and exact gear setup to find a useful next move.
- Get a clear diagnosis grounded in up to 50 matching brews.
- Change one small thing while keeping the rest of the recipe constant.
Statistics
Turn a year of brewing into answers.
See quality, consistency, taste, rhythm, recipe performance, gear usage, and costs—not just a count of cups.
- Filter trends by date, bean, method, recipe, rating, or gear.
- See how changes to grind, dose, pressure, and time affected the cup.
Café visits
Remember the cafés worth returning to.
Keep your coffee life away from home in the same journal: what you ordered, where you went, what it cost, and how it tasted.
- Link drinks to saved cafés and beans, with ratings and tasting notes.
- Map visited places, favorites, and the cafés still on your list.
Gear management
Save your setup once. Reuse it everywhere.
Catalog brewers, machines, grinders, baskets, scales, and accessories, then connect the exact setup to every brew.
- Group equipment into gear sets that fill a new brew in one tap.
- Keep documented machine settings and brew history with the gear itself.
More coffee. Less setup.
