Callirra

Callirra is a unified AI media generation workspace that brings the industry's leading image and video models under a single account, a single credit balance and a single interface. Positioned as a cost-efficient alternative to stacking multiple model subscriptions, it aggregates MiniMax H3, Seedance 2.x/2.5, Kling 2.6/3.0, Veo 3.1, Gemini Omni, GPT Image 2.5 (Flare and Sunburst), Nano Banana 2 and Pro, Seedream 5 Pro and Lite, and roughly 40 catalog entries, letting users switch generation engines in one click without re-uploading assets or managing separate bills. The target audience spans first-time creators testing AI generation with free weekly credits, active solo creators and marketers who need a steady output budget, and studios or teams requiring high-volume, high-priority rendering with commercial usage rights. Core features include text-to-image and text-to-video generation, first/last-frame conditioning, up to 9-16 reference images, 480P to 4K output, transparent backgrounds, watermark-free paid exports, a shared asset library, reusable prompt packs, 200+ ready-made prompt templates, an Image Prompts Studio, Context-IR shot expansion, a separate wide-limit Seedance route with broader moderation and a 20,000-character prompt ceiling, and 18 free credits in the first week followed by 15 every week. Content features include worked showcase scenes with published prompts and settings, a prompt atlas hosted on GitHub, pre-generation credit cost transparency, and a dedicated landing page per model. User experience emphasizes one workspace, one bill, no hidden fees, instant cancellation in Billing, a 7-day refund on unused credits, and every result saved to a personal library. Technical features include identical accounts, balances and prices across the web generator, HTTP API, CLI and MCP server, auto-translation and tagging, priority queues supporting 2-12 concurrent generations, secure checkout through Visa, Mastercard, Apple Pay and Google Pay, and automatic credit refunds for failed generations.
