TALLYSCOPE — by Ostiumlab
Every particle counted, every count verifiable.
Computer-vision counting for nanoparticles, colonies, and crowded microscopy fields — with a confidence interval attached to every result, not just a number.
Built for the person who has to defend the number.
Materials scientists sizing nanoparticles from TEM and SEM images. Microbiology teams counting colonies on crowded plates where manual counts disagree with each other. Anyone who's submitted a particle count in a report and been asked "how sure are you?"
We needed a count we could stand behind.
Manual counting doesn't scale, and most automated counters give you a number with no sense of how much to trust it. TallyScope reads its own scale bar, flags particles it hasn't seen before, and turns every correction you make during review into a verified accuracy score with a confidence interval.
A number without its uncertainty isn't a result.
TallyScope has been validated at 98–100% count accuracy across colony, nanoparticle, and crowded-field tests — and where per-particle sizing gets noisier in dense clusters, that's stated too, not smoothed over.
