OneOver
What is OneOver?
OneOver is a creative studio that puts multi-model chat, image generation, video, voice, and music in one browser workspace. You can run GPT, Claude, Gemini, Grok, and dozens of other models in a single thread, attach PDFs and images, flip on web search, and swap models without losing context. Guests get five chat messages before signup, and new accounts receive 50 one-time starter credits.
Where most tools make you pick one provider and buy separate subscriptions for images or video, OneOver routes everything through one shared credit balance. Subscription refills, plan bonuses, and pay-as-you-go packs all spend across chat, diffusion, video, speech, music, and playground mini apps. Switching from GPT-5.4 Nano to Claude Opus 5 is a dropdown change in the same conversation, not a copy-paste hop between sites.
Creators and marketers use OneOver to draft copy, iterate visuals, and turn prompts or photos into short clips from one library. Developers can hit the same model routes through a REST API with streaming support. Pro and Studio also ship seat-based team plans that pool monthly credits with member soft limits and one invoice.
Helicone
What is Helicone?
Helicone is an open-source AI gateway and observability platform for production LLM apps. Point the OpenAI SDK at https://ai-gateway.helicone.ai and you can call 100+ models from OpenAI, Anthropic, Google, and other providers while Helicone logs latency, token usage, cost, and errors automatically.
Most model routers charge a markup and bolt observability on later. Helicone combines routing with monitoring: automatic provider failover, cross-provider caching, granular rate limits, session tracking, and a unified dashboard for debugging prompts. The credits product advertises 0% markup on model usage, so you pay provider rates plus standard payment processing rather than a platform surcharge.
Helicone's Hobby plan includes 10,000 monitored requests per month with a 7-day retention window, while Pro and Team tiers add longer retention, higher ingestion limits, prompts, datasets, and gateway features like caching and automatic fallbacks. The company is open source with self-host and managed cloud options, and the homepage notes Helicone joined Mintlify in 2026.
