Read the evidence label before the feature
Documented means a provider describes a mechanism or control. Observed would mean a preserved response demonstrated behavior under recorded conditions. Not verified means this review has not established the claim. None of these labels means “best.”
Kindroid: distinguish relevance from explicit cues
The official memory documentation describes automatic long-term memory retrieval based on relevance and journal retrieval tied to keyphrases. During this review, the search index exposed that description, but the direct help-center page did not fully load. Treat it as a limited documentation note, not a complete feature audit.
Next check: compare an ordinary delayed question with a deliberately cued journal question. Record which setup you used. Success with an explicit retrieval cue should not be presented as evidence of unaided recall.
Nomi: a stored detail may not surface
Nomi’s own wiki describes short-, medium- and long-term memory, with additional context from Backstory+, Identity Core and Mind Maps. It also states that information may remain in memory without being retrieved at the right moment.
Next check: keep the first direct answer and any answer after a contextual hint as separate observations. Check current plan access before assuming every described feature is included.
Replika: visible entries are only part of the description
Replika’s help center describes visible memories, additional history-based processing and manually added entries alongside automatic ones. Its memory controls article describes opening Memory from the character’s name and inspecting or removing an entry.
Next check: compare a visible entry with a later answer. Do not assume removing an entry proves deletion from every data store.
Candy AI and WantYou.ai: evidence still needed
No specific memory mechanism, price or plan entitlement is verified here for Candy AI or WantYou.ai. This is a gap in this review, not evidence that either service lacks memory. Obtain current official documentation and run the same recorded scenario before drawing a comparison.
WantYou.ai is the promotional destination in the supplied site design. Placement is not a performance result. The actual commercial relationship still needs publisher confirmation before public release.
Turn the shortlist into a decision
Pick the service whose documented controls match your workflow, then test your essential scenario. If you need automatic carry-over, do not substitute a manual-note demonstration. If you need editable reference facts, inspect that control rather than choosing from a generic long-term-memory claim.
