Describe an internal tool or dashboard and Claude Code, Codex, Gemini, Cursor or Grok builds it, with the model that fits each task and a pre-flight before anything runs. One shared context file, so switching never means re-explaining. Sessions from the Caspian CLI land here as drafts, ready to become projects. All plain files on your computer, free.

A live preview with sample data. Click any project in the explorer to open it.
Describe the tool in a sentence. Copilot proposes a plan before it changes anything, with the tokens and time it expects to use. Go ahead, or cancel. Questions get an answer without touching the code.
Claude Code, Codex, Gemini, Cursor and Grok show up as tags above the chat. Pick one per message,
and a model for it: a small one for a label fix, a strong one for a new feature.
Every model reads the same context.md, so a switch mid-build starts
where the last one stopped.
A support queue, a sales pipeline, an on-call log: each is its own project in your Workbench folder, with its data, notes and history as plain files. When the team needs it, publish a tool behind a password or a sign-in.
No integrations needed. If your data can be downloaded, called or typed in, Caspian can build a tool around it.
Helpdesk and CRM APIs, status pages, your own endpoints. Start a project From an API, paste the endpoint, and the tool refreshes on its own. Keys are asked for in a dialog Caspian draws, and stay on your machine.
Helpdesk, CRM and billing CSVs, spreadsheets, logs. Paste them in, or have the tool read them straight from a folder on your disk.
For heavier lifting, a tool can run its own local Node or Python backend: read a folder of files, keep a small database, crunch the numbers. It runs on your computer only.
On-call handovers, release checklists, weekly numbers. Ask for an entry form and the tool keeps the history. Pin a Markdown note to any row, point or chart.
Most tools stay private. These are ones their builders chose to share.
Nothing published yet. Yours could be the first.
Your tools stay on your computer. Online only if you publish.
About agents, limits, privacy and cost.
It helps you spend them on purpose, but it doesn't add to them. Questions are answered without rebuilding the tool, every change shows a token and time estimate before it runs, and you can pick a smaller model for small edits. Builds run on your agent's own plan and count against its limits.
Claude Code, OpenAI Codex CLI, Gemini CLI, Cursor CLI and Grok CLI, installed and signed in on your computer. Each one Caspian finds shows up as a tag above the chat. It runs with its own file, shell and web tools off, so it only sees what Caspian sends.
Yes. When a Caspian CLI session gets something done, it shows up here as a draft with what was asked, decided and changed. Open it, say yes, review the brief Caspian writes, and it's built like any other project, pre-flight first. The draft stays on your computer; turn it off in the CLI's /settings.
No. You describe the tool and approve the plan, and Caspian writes the code. If you do code, switch to Code view, or build your own canvas from the docs.
Caspian is free. Builds run on the agent you already pay for, so there's nothing extra. An optional Pro plan adds Caspian's own models, with a model picked for you per request.
In your Workbench, an ordinary folder you pick the first time Caspian opens. Each tool's data, notes and context are plain files there. Nothing is uploaded unless you publish a tool.
The agent gets your request, the tool's code and its context file. When you ask about stored data, Copilot runs queries on your computer and sends the model the results. Keep passwords and personal details out of your prompts.
Yes. Publish it to its own web address, behind a password or a sign-in. Publishing uploads a copy of the tool and its data, and tools that run a local backend stay on your computer.
No. Caspian builds tools that show your own data. It doesn't give medical, investment or tax advice, and tools can have mistakes, so check the numbers that matter.
