AI Companion Memory: Compare Recall with a Repeatable Test
Treat memory as something to check, not a guarantee printed on a landing page. A useful trial distinguishes facts from the current chat, saved character instructions and recall after a later session.
Shortlist from existing editorial reviews. Scores are estimates; only explicitly dated source checks are verified. Read the evidence policy.

Run these checks before choosing
- Give three harmless fictional facts and record them outside the app.
- Change topic, start a later session if available and ask neutral recall questions.
- Correct a fact once and check whether the correction persists; stop if private data is needed to make the test work.
Billing, platform and policy evidence
Nomi AI: sources and limitations
| Check | What the source establishes | Evidence and date |
|---|---|---|
| Price | The terms describe recurring subscriptions and paid add-ons, but this check does not establish a current comparable monthly charge. Confirm the total and interval on the selected subscription screen. | Quote required Official source |
| Free access | The official home page offers a free start without a credit card. It does not establish unlimited access to every voice, media or group-chat feature. | Documented Official source |
| Cancellation | Cancel through the purchase platform. The web route is Profile, Subscription, Manage Subscription, then Cancel Subscription. Store purchases use Apple or Google controls. Benefits last to period end; deleting the app is not cancellation. No account action was tested. | Documented Official source |
| Privacy | The notice covers chat and customization content, service and legal disclosures, and account deletion in about 28 days after confirmation. Support archives have exceptions; no-sale wording is not proof of confidential chat. | Documented Official source |
| Platform | The cancellation guide documents web, iOS and Google Play purchase routes. Availability and displayed prices can differ by store region. | Documented Official source |
| Age and suitability | The terms require users to be at least 18 and prohibit relying on Nomi for medical, mental-health or other professional advice. | Documented Official source |
Who should skip it: Skip Nomi if you need a guaranteed memory result, medical advice or a verified monthly quote without checking your own plan. Keep sensitive information out of the trial.
Kindroid: sources and limitations
| Check | What the source establishes | Evidence and date |
|---|---|---|
| Price | The help center lists Standard at $13.99/month web and $15.99/month app. Combined monthly totals are $38.98/$44.98 with Ultra and $98.97/$113.97 with Ultra plus MAX. Regional charges can vary; checkout was not completed. | Documented Official source |
| Free access | The help article describes limited Lite access and a separate three-day premium trial requiring payment details that renews unless canceled. Web trial signup also requires phone verification. Recheck availability before starting. | Documented Official source |
| Cancellation | Web subscriptions use Billing in settings; store purchases use the relevant store. Each add-on is a separate subscription: canceling Standard or Ultra can reduce service while a higher add-on still bills. Review every active tier; no cancellation was operated. | Documented Official source |
| Privacy | The legal notice describes chat and media retention until AI/account deletion, service-provider processing and legal exceptions. It reserves decryption for specified legal or enforcement purposes; public/shared content may survive deletion. Encryption is not a confidentiality certification. | Documented Official source |
| Platform | The subscription help documents web, iOS and Android access and billing. Subscription status follows the login account, but changing purchase platforms requires the old subscription to expire. | Documented Official source |
| Age and suitability | The Terms of Use require at least 18 or the local age of majority, whichever is greater. Kindroid is not medical care or an emergency service. | Documented Official source |
Who should skip it: Skip paid Kindroid tiers if you cannot distinguish the base subscription from recurring add-ons. Do not buy a costly memory tier solely from an advertised capacity or directory score.
Replika: sources and limitations
| Check | What the source establishes | Evidence and date |
|---|---|---|
| Price | The subscription help says pricing is shown in the app and relevant store. Compare the chosen tier and renewal interval; do not treat a legacy Pro price as the current Ultra or Platinum charge. | Quote required Official source |
| Free access | The trial FAQ says there is no free premium trial and describes free chatting. The subscription guide calls Free Use limited and subject to availability; neither statement establishes free access to every paid feature. | Documented Official source |
| Cancellation | The cancellation guide documents Settings, Subscription, Cancel subscription, but requires the purchase platform to manage billing. It separately covers Apple, Google and PayPal; deleting the app does not cancel. No account action was tested. | Documented Official source |
| Privacy | The policy permits de-identified conversation processing by third-party AI providers for replies, contractually excluding their model training. It describes internal safety training, messages retained up to 60 days after termination, and some account/financial records retained at least ten years. Not a confidentiality audit. | Documented Official source |
| Platform | The official home page describes native iOS and Android access and labels its browser link Web App (Legacy). Do not assume the newest app features are identical in the legacy browser client. | Documented Official source |
| Deletion | The erasure help describes sending a support request from the registered email and receiving confirmation. This is a documented route, not a deletion test or a promise to override every retention exception. | Documented Official source |
Who should skip it: Skip a Replika upgrade if you cannot identify the tier and billing owner. Do not use companion conversation as confidential record storage or a substitute for qualified professional help.
Candy AI: sources and limitations
| Check | What the source establishes | Evidence and date |
|---|---|---|
| Price | The public offer displays monthly, quarterly and annual USD charges. This is a public-page check, not a completed checkout; confirm the renewal amount and local taxes. | Documented Official source |
| Free access | The terms generally allow 5 free messages. Paid text access and token allowances are described separately; free messages do not establish free media. | Documented Official source |
| Cancellation | The terms direct users to Settings / Unsubscribe. Access lasts through the billing period, after which remaining subscription tokens expire. This route was not operated in an account. | Documented Official source |
| Privacy | The privacy notice describes de-identified interactions used for model development and human review. Financial records have a stated 10-year retention period; account deletion is not a promise to erase every record. | Documented Official source |
| Platform and region | The public site provides browser home-screen installation instructions. The terms prohibit access from China and Singapore; do not bypass those restrictions. Native app-store availability was not verified. | Documented Official source |
Who should skip it: Skip Candy if you require confidential conversations, access from China or Singapore, or media without a separate token allowance.
Know when to stop
Do not pay if the renewal amount, feature allowance or cancellation route remains unclear. Use fictional details during a trial. A feature advertised by a provider is not proof of quality, privacy or suitability for you.

Frequently asked questions
How can I test AI companion memory?
Give three fictional facts, change topic and return later if possible. Ask neutral recall questions without supplying clues and record corrections separately.
Is a long chat context window the same as persistent memory?
No. Information available within one conversation is different from saved instructions or recall in a later session.
Should I use private facts for an AI memory test?
No. Fictional details are sufficient to test recall. A correct answer does not establish privacy, reliable retention or secure deletion.
