None of these are bad.
But none of them is this.
Honest comparison of the most common ways people try to make a machine understand them.
You have probably tried several of these options. This is not a parade of green checkmarks. It is a table showing what each product does, what it doesn't, and a sincere section on what Afini still doesn't offer — because we have no intention of reselling you the same thing with fresher wrapping.
ChatGPT + Memory
Chatbot with partial memory. Users talk about themselves; the model picks what to retain.
Claude with Projects
Context per project. No central profile; each project starts nearly from scratch.
16Personalities Premium
Personality test with generic reports. Marketing polish over MBTI.
Character.ai / Replika
Affective conversational companion. Optimized for emotional retention.
Afini.ai
Quantified, portable cognitive profile. 5 tests + 11 conversations. Any AI reads it.
What they measure (really)
| ChatGPT + Memory | Claude with Projects | 16Personalities Premium | Character.ai / Replika | Afini.ai |
|---|---|---|---|---|
| Nothing structured. Remembers fragments (loose preferences, your dog’s name). | Context of the current project. No cross-project profile. | Four letters (MBTI renamed). Generic reports per type. | Conversation history + affective bonding. No psychometric model. | Big Five (IPIP-NEO 60/120/300) + attachment (ECR-R) + humor (HSQ) + values (AVI-25) + time (ZTPI) + cognitive/aesthetic style. 25 axes. |
Psychometric basis
| ChatGPT + Memory | Claude with Projects | 16Personalities Premium | Character.ai / Replika | Afini.ai |
|---|---|---|---|---|
| None. | None. | Controversial. MBTI lacks recognized statistical validity in academic psychology. | None. | Big Five (academic consensus). Empirical norms over 1,461,383 real respondents. |
Portability to other AIs
| ChatGPT + Memory | Claude with Projects | 16Personalities Premium | Character.ai / Replika | Afini.ai |
|---|---|---|---|---|
| None. Memory is not exportable in a format another AI can use. | None outside the project. You can copy prompts, not a profile. | None. Your "type" is not a protocol another AI understands. | None. Conversations are tied to the product. | Full. Self-contained JSON with interpretation protocol. Works in Claude, GPT, Gemini, DeepSeek, Kimi, local. |
Use of your data
| ChatGPT + Memory | Claude with Projects | 16Personalities Premium | Character.ai / Replika | Afini.ai |
|---|---|---|---|---|
| By default, yes. Opt-out exists but most users do not activate it. | No training on consumer user data. But context lives inside Anthropic. | Your answers feed their commercial research and recommendations. | Training on conversations (with relative anonymization). | Never. Explicit contract. Your data trains nobody. |
What survives cancellation
| ChatGPT + Memory | Claude with Projects | 16Personalities Premium | Character.ai / Replika | Afini.ai |
|---|---|---|---|---|
| You lose the memory. No export. Cancelling means a reset. | You keep projects while you keep paying. Cancellation archives them. | You lose the dashboard. The MBTI type in your head is worthless. | You lose the "relationship" and the conversational history. | Your profile remains yours (portable JSON). Whichever AI you pick still understands you. |
Languages
| ChatGPT + Memory | Claude with Projects | 16Personalities Premium | Character.ai / Replika | Afini.ai |
|---|---|---|---|---|
| ~95 interaction languages; memory is mixed. | Multilingual via prompt; no consistent UI. | 49 interface languages. | English-first; other languages uneven. | 6 languages (ES, EN, FR, DE, IT, PT). Fewer than 16Personalities. We say it out loud. |
Annual price
| ChatGPT + Memory | Claude with Projects | 16Personalities Premium | Character.ai / Replika | Afini.ai |

What we still don't give you (and won't pretend to)
Three concessions worth saying out loud before the user discovers them alone:
We are not a mass product.
16Personalities offers 49 languages and is taught in universities; ChatGPT has 800 million users. Afini runs in 6 languages and is built by a 2025 Spanish S.L. based in Bilbao. We give you rigor and portability, not scale.
There is no native mobile app.
We run on responsive web. Long tests (120 or 300 items) are better on desktop. If you were expecting iOS and Android with notifications and widgets, that is not here yet.
We do not replace a therapist.
Afini gives you a quantified cognitive map. That is not therapy, coaching or clinical diagnosis. If you are in acute emotional distress, this is not what you need — and anyone selling a psychometric profile as a substitute for professional care is lying to you.
If all of the above still sounds fair:
15 minutes for the first test. From €14.99/mo. Cancel whenever.
