The problem
Your AI stack is more complex than it needs to be.
Sound familiar? You're not alone. Teams everywhere are drowning in fragmented AI tooling.
Tab-switching hell
You jump between ChatGPT, Claude, and Gemini all day. Context is lost, conversations are scattered, and comparing outputs means copy-pasting between windows.
Cost blindspots
Every provider bills separately. You have no visibility into total AI spend, no way to compare cost-per-output, and rate limits surprise you at the worst times.
Prompts live in Slack and Notion
Your best prompts are buried in shared docs and message threads. No version history, no way to track what changed, no single source of truth.
Vendor lock-in
Your codebase is tightly coupled to one provider. Switching models means rewriting integrations, changing SDKs, and hoping nothing breaks.
Every model.
One conversation.
Switch between GPT-5.3, Claude Opus 4.6, Gemini 3 Pro, Grok 4, and 20+ models mid-conversation. Compare outputs side-by-side, attach files, and keep full history — all without juggling browser tabs.
Version control
for prompts.
Track every change with git-style version history. Compare diffs between versions, branch experiments, and roll back with confidence. Share prompt links with your team and publish to the community.
Deploy custom
AI agents.
Build specialized agents with custom instructions and tool access. Pair any agent with any model, share them across your organization, and iterate without redeploying infrastructure.
One API.
Every provider.
Integrate AI into your products through a single REST API. OpenAI-compatible endpoints let you switch models without changing a line of code. Route, log, and monitor every request.
const response = await fetch(
"https://api.grimoire.tech/v1/chat",
{
method: "POST",
headers: {
"Authorization": "Bearer YOUR_API_KEY"
},
body: JSON.stringify({
model: "gpt-4o",
messages: [{
role: "user",
content: "Hello"
}]
})
}
)How it works

Connect your API keys
Bring keys from OpenAI, Anthropic, Google, and 20+ providers. No middleman, no markup — you keep full control of your costs and rate limits.
Set up your workspace
Create and version prompts, configure custom agents, and invite your team. Everything in one organized workspace with role-based access.
Start shipping
Use the chat interface, deploy agents, or integrate via our REST API. Switch models mid-conversation and ship AI features at twice the pace.
Built different.
Not another AI wrapper. Grimoire gives you the infrastructure to own your AI stack.
Bring Your Own Keys

Organizations & Workspaces
Manage teams with role-based access, shared prompts, and workspace-scoped agents. Built for collaboration from day one.

Your API keys and conversations never leave your control. We don't train on your data, and you can self-host for complete sovereignty.
Trusted by engineering teams.
“We replaced three separate AI subscriptions with Grimoire. One interface for every model, version-controlled prompts our whole team can iterate on — it paid for itself in the first week.”
Sarah Chen
Head of AI Engineering, Meridian Labs
“The BYOK model was the deciding factor. We keep full control of our API keys, costs, and data. No vendor lock-in, no surprise bills — just a clean interface on top of the providers we already use.”
Marcus Rivera
CTO, Arcline Systems
“Grimoire turned prompt engineering from a solo activity into a team sport. Version history, shared workspaces, and the API gateway let us ship AI features at twice the pace.”
