Playful tools, clear boundaries, thoughtful design.

People have compared names, played FLAMES, asked symbolic questions, and shared couple photos for generations. Love Meter brings those familiar activities into one modern, accessible site. The goal is not to turn love into a number. Love Meter creates a moment to smile, start a conversation, remember a schoolyard game, or reflect on a question from a different angle. A playful interface, transparent method, and shareable result make the experience easy to understand.

Love Meter also responds to a common problem with online compatibility tools: unclear randomness presented as insight. When Love Meter uses a fixed algorithm, it says so. When Love Meter uses AI, it says so. When a result may vary, the page explains why. This distinction lets visitors decide how to interpret the output. Love Meter never hides a prediction behind technical language or claims that a model can verify affection, loyalty, compatibility, or the future.

The name Love Meter accepts two names and returns a Love Score, Chemistry Score, Couple Type, short explanation, and share card. FLAMES Calculator performs multiset letter cancellation and circular elimination for Friends, Love, Affection, Marriage, Enemies, or Siblings. Love Oracle uses lunar time values or three chosen numbers to select one of six reflective signs. These three Love Meter experiences are deterministic and store their algorithm versions.

Love Meter by Photo accepts one shared image or two separate images from a signed-in user. It describes visible color, framing, style, and atmosphere through a multimodal model. Love Meter by Photo does not identify private traits or judge the real relationship. The four tools share a visual language and result flow while preserving the differences between name calculation, a traditional letter game, a symbolic method, and image analysis.

Every Love Meter flow provides the basic result for free. The free reveal is not a blurred preview: it includes the main score or sign, the relevant secondary value, a concise explanation, a public result link, and a downloadable sharing card. Name, FLAMES, and Love Oracle can be used without an account. Love Meter by Photo requires sign-in because analysis and later paid readings need authenticated ownership.

An optional Love Meter AI reading costs 100 credits. Credits are sold in one-time packs through Stripe or PayPal, with no subscription and no automatic renewal. The server deducts credits atomically, prevents duplicate charges with idempotency keys, streams the report, saves the completed content, and refunds credits after a generation failure. This Love Meter model makes the price visible before generation and keeps the original free result intact.

Love Meter uses Unicode normalization and SHA-256 seeding for the name calculator, explicit multiset removal for FLAMES, and a documented six-position cycle for Love Oracle. These methods can be tested with fixed vectors and edge cases. Love Meter records the algorithm version on every result, allowing shared links to retain their meaning even if a later implementation changes. AI does not secretly select any of these free outcomes.

Text readings use an OpenAI-compatible streaming interface with a primary DeepSeek model and an OpenRouter fallback. Love Meter by Photo uses separate OpenRouter multimodal models for free analysis and paid interpretation. Prompts prohibit unsupported judgments about feelings, loyalty, personality, or future outcomes. Love Meter streams visible report text and progress stages, never hidden model reasoning. Model errors trigger a safe failure state and credit restoration.

A public Love Meter result contains only share-safe fields such as a score, result type, secondary label, short summary, and branding. Raw names, Love Oracle questions, photo bytes, claim secrets, and full paid reports are not returned by the public API. Anonymous results use an unguessable token and a separate browser-held secret for later account claiming. Private Love Meter readings verify ownership on every request.

Love Meter does not persist photo bytes server-side. The browser sends base64 image data directly for the requested analysis and can retain an optional IndexedDB copy for up to 24 hours so a paid reading survives a payment redirect. That local cache is deleted after successful report generation or expiration. Users can delete their account and associated server-side data from Profile.

Love Meter will not claim that a score proves affection, that a photograph reveals loyalty, that FLAMES predicts marriage, or that Love Oracle guarantees an event. Love Meter results are prompts, labels, and stories built for entertainment. They should never replace consent, direct communication, observed behavior, professional advice, or attention to safety. Repeating a result until it becomes comforting does not make it more true.

A good Love Meter experience leaves someone feeling curious rather than controlled. Share cards avoid exposing private inputs. Accessibility choices include keyboard support, clear labels, touch targets of at least 44 pixels, and reduced-motion behavior. Love Meter is designed to welcome international text even though the first release is English-only. The next-intl architecture and centralized messages make future languages possible without scattering English copy throughout components.
