About

Oqta

Features
Read full description

Oqta is an independent iPhone client for OpenRouter users who want model choice, clear costs, and local-first control. Connect your OpenRouter account with OAuth, or add an API key if you prefer. Then chat from a native iOS app built for people who switch models instead of staying locked to one assistant. With Oqta, you can: โ€ข Switch models quickly with favorites, search, and a curated picker โ€ข Chat with text models and send image or PDF attachments where supported โ€ข Generate images and videos through supported models โ€ข See model, provider, token, speed, and cost details when OpenRouter returns them โ€ข Use optional web search through OpenRouter or LinkUp after a clear consent step โ€ข Keep normal chat history local-first, use Private Chat when you do not want persistence, and export or delete your data from the device Oqta has no chat backend. Your OpenRouter user key or API key is stored in iOS Keychain and is not synced to iCloud. Messages, attachments, recordings, search queries, and generated media are sent only when you choose features that require OpenRouter, LinkUp, or the selected model provider. Oqta does not sell OpenRouter credits. OpenRouter account usage, model availability, provider behavior, pricing, and retention policies are controlled by OpenRouter and the selected model providers.

About

MelMat

You can't afford to be wrong. MelMat makes sure you aren't guessing. Ask any question and MelMat runs four leading AI research engines on it at once โ€” then synthesizes their answers into a single, structured brief: a clear summary, the key findings, the points where the engines agree, and the contradictions most tools quietly bury. Because the real risk isn't a wrong answer. It's a confident wrong answer. MelMat scores how strongly the engines agree and surfaces exactly where they diverge โ€” so you know how much weight a finding can bear before you act on it. Built for people who are accountable for being right: in healthcare, law, finance, real estate, consulting, and beyond. WHAT YOU GET - Four research engines on every query โ€” never a single point of failure - Structured briefs: summary, findings, points of consensus, contradictions, what to do next - A consensus score so you know how strong the signal really is - Grounded against authoritative public data sources, not just model memory - Mยฒ Chat โ€” ask MelMat anything, conversationally, anytime - Dig Deeper โ€” interrogate any brief: "show me where they disagreed," "what's the weakest claim," and more - Download or email any brief as a polished PDF MelMat is a multi-model synthesis platform. The engines are the inputs. The synthesis โ€” the judgment about what to trust โ€” is the product. Patent Pending.
