unbeatable for on-device and edge retrieval — brute-force only, so know where the ceiling is, and know it's still alpha.

our verdict

unbeatable for on-device and edge retrieval — brute-force only, so know where the ceiling is, and know it's still alpha.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
