Afini vs Pi
Pi is friendly. Afini knows you.
Pi was born as a "personal AI" with emphasis on empathic conversation. It got popular; in fact, too much — Inflection AI, the company behind it, was effectively "acqui-hired" by Microsoft in March 2024. The product lives on, with less focus. Afini goes to the bone: we do not sell friendliness, we sell a quantified profile. Friendly AI is everywhere; AI that actually knows you, less so.

How your data is processed
Axis by axis
| Afini.ai | Pi | |
|---|---|---|
| What the product is | Quantified cognitive profile + personalized AI. 5 validated psychometric tests and 11 guided conversations that combine into a profile that travels with you. | Conversational AI designed for empathic interaction ("personal AI"). No tests, no structured profile. |
| How it knows you | Your profile is injected as a system prompt on every conversation. The AI does not "remember scattered bits": it reads your full profile before answering. | Conversational memory retaining fragments over time. Warm tone and open questions. No visible or editable profile. |
| Integrated psychometric tests | IPIP-NEO (Big Five, 1.46 M respondents), ECR-R (attachment), HSQ (humor), ZTPI (time), AVI-25 (values). Five instruments with published validation. | None. Learns from conversation without validated instruments. |
| Sycophancy safeguards | The proxy injects an anti-sycophancy block with 5 explicit directives. If your profile scores high on Agreeableness and Neuroticism, a formula kicks in to disable flattery. | The empathic tone IS the product. Structurally, Pi validates more than confronts. No explicit user control over how much it flatters. |
| Privacy and training | Your data does not train Afini or Anthropic. Explicit contract. Tests are anonymous by default; the profile is yours and exportable. | Data on Microsoft/Inflection infrastructure after the 2024 deal. US jurisdiction. Evolving policies. |
| Profile portability | Portable JSON with an interpretive protocol. Inject it into Claude, GPT, Gemini, DeepSeek or your own infra. €249 one-time or included in the annual plan. | No export of the "model understanding" in a portable format. |
| Underlying AI model | Claude Sonnet 4.6 on Essential; Claude Opus 4.6 on Premium and Professional. Anthropic model, injected via our own proxy. | Inflection engine (Pi 3.0+). After the Microsoft deal, core staff moved to Microsoft AI. Engine’s future evolution, uncertain. |
| Price | €14.99/mo (Essential), €29.99/mo (Premium), €49.99/mo (Professional). Portable JSON: €249 one-time or bundled with annual plans. | Free · Paid plans poorly advertised and in flux after the Microsoft deal. No profile export (does not exist). |
| Languages and norms | 6 languages with informal register: Spanish, English, French, German, Italian, Portuguese (Brazil). Empirical percentiles normed by country where data exists. | Multilingual, English-heavy. No country-level norms. |
| Company behind | Bilbao AI S.L. — Spanish company, Holded invoicing with TicketBAI/BATUZ. Privately held, no VC rounds. An identifiable human to talk to. | Inflection AI (founded by Mustafa Suleyman and Reid Hoffman). In March 2024 Microsoft paid ~$650 M to license the tech and hire the team — Suleyman now leads Microsoft AI. Pi still runs; the original company is a shell. |
Where Pi wins
No sugarcoating. Selling a cognitive profile requires admitting other products do some things better. Here they are.
Conversational warmth
Pi sounds like a friend. If all you want is to vent to someone patient, Pi does that job better than Afini — which comes with a profile and uncomfortable questions.
Zero entry barrier
You open Pi and talk. Afini asks you to complete tests and conversations before handing you a profile. More initial friction, yes; also more substance later.
Where Afini wins
Verifiable claims. No "we are the only ones who truly understand you". Numbers, formats, protocols.
Visible, editable profile
You see your profile as data: 30 Big Five facets, 2 attachment dimensions, 4 humor styles, 10 values, 5 time orientations. You can review, recalibrate and export it. Pi does not show what it "knows" about you.
Operating, focused company
Afini is Bilbao AI S.L., with a roadmap and people working on the product full-time. Pi is what remains of Inflection after losing its founders and core team to Microsoft.
Engine you choose, indirectly
Your profile is portable. If Afini disappears tomorrow, you take the JSON and drop it into any LLM. Pi ties you to Inflection’s evolution (or extinction).
What each plan costs in Afini
Questions you are asking yourself
- Does Pi still exist?
- Yes, as of April 2026, though its future is hazy. Microsoft hired the core team in 2024 and Suleyman now runs Microsoft AI. The product is still operational but development has slowed. Keep that in mind before investing your time (and your intimacy) in the platform.
- Can Afini be as warm as Pi?
- If your profile shows anxious attachment, high Agreeableness and low conflict tolerance, Afini will adjust tone to that warmth. If you are more skeptical and cynical, the AI will be drier. Tone is not the product; it is a consequence of your profile.
- Should I worry about the Microsoft deal?
- Depends on how much you care about product continuity and data jurisdiction. The deal is not a clean acquisition: tech licensing and staff hiring. That usually ends up being a de facto acquisition with residual maintenance. Not a great signal for an "intimate" tool.
- Will Afini last?
- We cannot guarantee survival (no one can). What we do give: the portable JSON. If Afini disappears, your profile survives because it lives on your machine and works in any LLM. The difference between building on Facebook and building on HTML.
- And if what I want is an AI that understands me emotionally?
- Pi will answer with generic warmth. Afini, with warmth calibrated by your profile — including attachment anxiety, Neuroticism, humor style and values. "Understand emotionally" is not the same as "sound kind": the first takes data about you, the second a system prompt.
