Last week, Ankihub suggested that I do an optimization. I did it through them and not the usual optimization and I noticed that my good interval with fuzz were around 3-4 days.
I then optimized a few days later on anki directly. My good intervals bounced back to what I am normally used to (5-8 days).
My question: Is going through optimization using Ankihub different than conventional Anki settings? It seems weird that my good settings’ interval was specifically like that only after using the prompt from Ankihub
I’ll help you understand if there’s any difference between optimizing through AnkiHub versus directly through Anki. Let me search for information about this topic first.

AnkiHub Optimization vs Anki Optimization
Based on the information available, there’s no official documentation indicating that AnkiHub’s optimization process differs from Anki’s standard database optimization.
The database optimization in Anki is primarily about improving database performance by cleaning up unused space and rebuilding indices - it shouldn’t directly affect your review intervals.
The difference in intervals you’re experiencing (3-4 days after AnkiHub optimization vs. 5-8 days after Anki optimization) is interesting and could be due to several factors:
-
Card scheduling protection: While AnkiHub is designed to protect your card scheduling (as mentioned in their FAQ), there might be edge cases where optimization through different paths affects review timing differently.
-
Fuzz factor: Anki applies a small random “fuzz” to prevent cards introduced at the same time from always coming up for review together. This fuzziness can vary between 0.8x-1.2x of the intended interval.
-
Interval modifier: The interval modifier in your deck settings (found under Deck Options > Advanced) might have been inadvertently changed during one of the optimization processes.
-
Coincidental timing: The change in intervals might be coincidental with other changes to your study patterns or deck settings around the same time.
If this issue persists, I’d recommend:
- Checking your deck options to ensure the interval modifier is set to your preferred value
- Monitoring if the pattern continues after future optimizations
- Reaching out directly to AnkiHub support if the issue persists
Since this appears to be a unique situation without direct documentation, you might want to create a specific support ticket with the AnkiHub team to get their official response on whether their optimization process differs from standard Anki optimization.
Hello,
I would be happy to help. 
The optimization function is the same.
The same optimization protocol runs regardless, and is a function of FSRS. AnkiHub doesn’t have any effect on it, other than suggesting that you optimize as a reminder. Any changes that were made are due entirely to the FSRS algorithm, as a rule
Please let me know if that answers your question, and if there’s anything else I can help with.
