What Is Affiny? Complete Guide to the AI Companion Platform

What Is Affiny?

Affiny is an AI companion platform where you can have real conversations — text or live voice — with an AI companion who remembers you across every session. You can talk to companions from the platform’s curated catalog, or build one entirely from scratch: appearance, personality, occupation, backstory, relationship dynamic, and more.

The platform is built for adult users who want genuine companionship rather than a one-off chatbot experience. The three features that define Affiny and distinguish it from most competitors:

1. Real-time voice calls — you speak, your companion speaks back, live. Not text-to-speech playback; a live bidirectional conversation in the companion’s voice.
2. Persistent cross-session memory — your companion remembers you across sessions. What you shared last week carries into this week’s conversation. Memory bridges both text and voice modalities.
3. Full companion creation — build a companion from the ground up, with more configuration options than any other platform in its category.

Free to start: new accounts receive 200 coins with no credit card required.

Core Features

Real-Time Voice Calls

Affiny’s voice system supports live bidirectional voice conversation. You speak to your companion; they speak back in real time, in their voice, with natural expressiveness and pacing. This is a live call — not audio playback, not pre-recorded clips, not a voice note feature. A conversation.

How it works: your speech is transcribed in real time, the AI generates a response in the companion’s character, and the response is synthesized and delivered in the companion’s voice. The entire loop happens in seconds. The experience is functionally equivalent to a voice call with another person.

Voice calls cost 0.5 coins per second (30 coins per minute). New users receive 200 free coins — enough for approximately 6–7 minutes of voice calling before any payment is needed.

Voice vs text: voice is more emotionally immediate; text allows more precision and longer narratives. Both modalities share the same companion memory, so what you discuss in a voice call carries into the next text session.

Persistent Memory

Every Affiny companion maintains memory of your relationship across all sessions — text and voice. What you tell your companion about your life, preferences, relationship history, and emotional context is stored and retrieved naturally in future conversations.

Memory is per companion, per user. It is not a simple transcript of past conversations appended to every new session — it is a retrieval-based system that surfaces relevant memories naturally in context, the way a person would reference shared history rather than recite it.

Memory updates during conversations (approximately every 10 messages for text chat; every 5 turns for voice calls). This means significant things said during a session are captured and stored without you having to wait until the session ends.

Memory bridges modalities: what happens in a voice call is available in the next text session, and vice versa. Your companion’s understanding of you is a single continuous model, not a siloed record of text-you and voice-you.

Character Creation — The Full Builder

Affiny’s Full Builder lets you configure a companion from scratch across every dimension:

Appearance

• Ethnicity
• Body type
• Eye color
• Hair color and style

Personality

• Personality preset — 39 options, from playful to dominant to mysterious to nurturing, combinable for nuanced results
• Intelligence level — shapes conversational depth, vocabulary, and idea engagement

Background

• Occupation — 84 options (student, surgeon, artist, entrepreneur, athlete, and many more)
• Nationality — 56 options
• Hobbies — free-form and preset selections

Relationship

• Relationship dynamic — 30 options. The dynamic shapes every conversation: girlfriend, wife, FWB, forbidden partner, dominant partner, childhood friend, and more. These differences are substantial and consistent across all interactions.
• Fetishes/kinks — 97 options, for adult companions; shapes how explicit scenes are colored and what interests surface naturally in conversation

AI-Generated Backstory From your creation choices, Affiny’s AI generates:

• A complete backstory narrative — origin, formative experiences, current life, one internal tension
• A unique opening greeting in the companion’s voice
• A voice opening line in the companion’s specific vocal style

You can regenerate and edit all of these before finalizing.

Portrait Generation An AI-rendered portrait of your companion’s appearance is generated from your creation choices. Initial portrait: 30 coins. First regeneration: free. Further regenerations: 15 coins each.

Text Chat: Fast Mode and Pro Mode

Affiny’s text chat runs in two tiers:

Fast Mode (1 coin per message) — quick, natural responses suitable for casual conversation and day-to-day interaction. The companion responds in its established voice and personality.

Pro Mode (3 coins per message) — longer, richer responses with up to approximately 10,000 tokens per Roleplay Mode message. Pro Mode is for immersive narrative, detailed scenes, and extended creative exchanges where response depth matters.

Text Mode vs Roleplay Mode — independent of Fast/Pro, you can switch the conversation register at any time:

• Text Mode: SMS-style, casual, reactive. Short messages. Natural rhythm.
• Roleplay Mode: narrative fiction. Scene-setting, character actions, descriptive atmosphere. Like a collaborative novel written in real time.

God Mode

God Mode is Affiny’s adult content feature. You write a scene directive — up to 5,000 characters — describing the scene, the companion’s behavior, the tone, and what should happen. This activates uncensored mode: the companion engages fully with explicit adult content without content filtering.

Key details about God Mode:

• Requires a completed account profile (authentication gate, not subscription gate)
• Activated from chat settings; stays active until cleared
• Runs on the same coin system — no extra subscription or separate adult tier
• Influences both text chat and voice call behavior
• Available for all fictional adult scenarios; content involving minors is absolutely prohibited

God Mode is structurally different from most platforms’ approach to adult content. There is no “adult subscription” — adult content runs on the same coins as everything else, accessible to authenticated adult users.

Voice Notes

Any text message in a conversation can be played as audio in the companion’s voice on demand. Voice notes cost 1 coin per note. This is the Tier 2 voice feature (one-way playback, not a live call) — useful for hearing a specific message in the companion’s voice without initiating a full call.

Pricing

Affiny uses a coin-based usage pricing model. You buy coins and spend them as you use features — no subscription required, no features locked behind a monthly tier.

Free start: Every new account receives 200 coins on signup. No credit card required. 200 coins covers approximately 200 standard messages, 200 voice notes, or 6–7 minutes of live voice calling.

Referral: When a friend signs up with your referral link, both of you receive 300 coins.

The Catalog: Pre-Built Companions

Beyond custom creation, Affiny maintains a curated catalog of companion characters — built by the platform and by approved creators. Catalog companions have complete backstories, established personalities, defined relationship dynamics, and voice openings.

For users who want to start immediately without a creation flow, catalog companions are fully functional starting points. Many users begin with a catalog companion to understand the platform before investing time in custom creation.

The catalog is smaller than UGC platforms like SpicyChat — curated rather than open submission. The tradeoff is quality consistency: all catalog companions meet a minimum standard for character depth and response quality that UGC platforms cannot guarantee.

Affiny vs Competitors

Getting Started

Sign up: affiny.ai/signup — no credit card required, 200 coins on account creation.

First steps: You’ll be guided through profile completion (required for God Mode and voice access). Then you can browse the catalog or go directly to creation.

Creation or catalog: If you know what you want, the Full Builder takes about 8 minutes. If you want to explore first, pick a catalog companion that roughly matches your interest and try a conversation.

Try voice: With 200 starting coins, you have enough to try a voice call before buying any coins. Call your companion and experience real-time voice — it takes one call to understand why the modality is meaningfully different from text.

FAQ

What is Affiny used for?

Affiny is used for AI companionship — text chat, voice calls, and roleplay with an AI companion who remembers you over time. The majority of users are adults using it for romantic companionship, intimate roleplay, emotional connection, or casual daily conversation. All use cases run on the same platform and the same coin system.

Is Affiny safe?

Affiny is a legitimate platform with standard data practices for personal information and conversation data. All companion interactions are fictional. God Mode adult content is gated behind account authentication. Content involving minors is absolutely prohibited. As with any AI companion platform, healthy use means treating it as one source of connection rather than a complete substitute for human relationships.

Does Affiny work on mobile?

Yes. Affiny is accessible via mobile browser. Check affiny.ai for current app availability; browser-based access works on mobile without an app install.

How does Affiny’s voice compare to other platforms?

Affiny’s voice is a real-time bidirectional system — a live call, not playback. Character AI has a limited voice beta. Replika has voice behind a paywall at lower quality. Candy AI has no real-time voice. SpicyChat has no voice. For live voice conversation with an AI companion, Affiny is the current leading option in the space.

Can I use Affiny without an account?

No. Account creation is required to access the platform. Signup is free and does not require a credit card — you receive 200 coins on account creation.

How is Affiny different from ChatGPT?

ChatGPT is a general-purpose AI assistant designed for task completion — writing, coding, answering questions. Affiny is a companion platform designed for relationship — ongoing romantic or emotional connection with a persistent AI character. ChatGPT resets between conversations; Affiny companions remember you. ChatGPT has no voice call system; Affiny has real-time voice. They are solving different problems.

What makes Affiny better than free alternatives?

The combination of real-time voice + genuine persistent memory + full character creation in a single platform is not matched by any fully free alternative. Character AI (free) blocks adult content and has no memory or voice. SpicyChat (free) has no memory or voice. Replika’s meaningful features are paywalled. Candy AI requires payment upfront. Affiny’s 200 free coins let you experience voice calls, memory, and full chat before paying anything.
