The app shows your plan's numbers right after sign-in and keeps showing them, with what is used, on the Me screen. This page explains what each number means for your photos.
The free plan and every current Opensolr plan include 500 AI requests a month; opensolr.com/pricing offers bigger allowances, and the API quota page explains how requests are counted. A request is counted only when a model really ran: a picture, words or a search Opensolr already answered come from its cache and cost nothing.
Without it no photo is read: photos are indexed by date, camera, place, file name and your own words, and found by those words. See without photo recognition.
Descriptions only, never pictures.
Resets every month.
Creating the phone's index fails when the account has no room left.
One AI request covers ten photos, so Photos per month is the monthly AI allowance times ten, and Photos left this month does the same with what is left of it. A plan with no monthly cap shows No monthly cap.
Opensolr keeps what it read: a picture it has already read comes from its cache, so a reinstall, a lost index or a Reset never pays for reading the same pictures again. A reinstall reads the whole index back into the phone's copy once, and that one read counts against search bandwidth.
On a plan without vector search, see what works and what does not.
At 90% of the disk space, of the month's search bandwidth or of the month's AI requests, and again at the limit, the app posts one notification and shows the same warning in the Account stats group of the Me screen. A plan without photo recognition is said there too: Photos are not recognised on your plan. Each notification is posted once; the monthly ones come back every month.
Nothing stops. New photos are still indexed with everything the phone knows about them (date, camera, place, file name, your words), only without being read and without a vector; the Sync screen says how many. At the first sync after the allowance resets, or after an upgrade, those photos are read. A photo already in the index keeps what was read out of it, as long as it is the same file. Search runs on words only meanwhile.
A notification that opens your Opensolr account; the Sync screen says the index reached its disk space or bandwidth. Tagging is not blocked: tags and names go on being saved on the phone while the index is closed, and go up on the first sync after the limit clears.
The setup screen says: Your Opensolr plan cannot hold another index. Remove an index you no longer use.
Nothing is lost. After an upgrade, or when the month rolls over, the next sync continues where the last one stopped. The notification and the Me screen open your Opensolr account on opensolr.com in your browser.
