A multi-agent AI answer engine. One conversational surface; twelve specialists behind the scenes.
What it is
Simplexicity is built around a simple idea: most AI tools force you to pick the right model, the right prompt, the right tool. We do that for you. A router reads each question and dispatches it to the specialist best suited to answer — search and source-extraction for research, sandboxed code execution for engineering, formal-reasoning models for math, image generation for visuals, document and slideshow generators for real downloadable artifacts.
Then a single voice answers — yours. The user never sees the orchestration. Just the right answer.
How it works
Capability tiers. Internally, each turn routes to one of seven tiers — Fast, Standard, Premium, Reasoning, Research, Image, Memory — depending on what the question needs. Casual questions get a fast direct answer; research questions fan out across multiple sources; engineering questions run real code in a sandbox.
Persistent memory. Three layers: a per-thread scratchpad agents share within one chat, a vector store of summary points across all your threads, and a structured user-facts table for things like name, preferences, and ongoing projects. All toggleable per-thread (incognito) or globally in settings.
Real artifacts. The document agent produces .docx files. The slideshow agent produces real .pptx decks with speaker notes and per-slide imagery. The image agent produces actual generated images. Files attach to the message as downloadable chips — you keep them.
Spaces. Project-scoped containers with their own system prompts. Threads inside a Space inherit the directive automatically — useful for "everything I write here should match this brand voice" or "this thread is for working on a specific paper."
Citations. Every research claim links back to its source. We extract content with full-page readers, not snippet APIs, so you see what the source actually said.
Plans
Plus — $25 / month. 1,500 credits/day. Standard-tier models, full memory, Spaces.
Pro — $50 / month. 5,000 credits/day. Premium, reasoning, and research tiers. Critic Agent for high-confidence mode.
Free AI products subsidize their cost by selling something — your data, your attention, your training signal. Simplexicity doesn't. Every plan is paid; every credit reflects real underlying inference cost; nothing about your conversations is sold to anyone. We'd rather have a smaller community of users who trust us than a larger one we have to extract value from.
