Build it once. Use it everywhere you work.
Your Callstand holds how you do your work. Connect it to Claude, ChatGPT or your own tools, share it with your team, and every answer comes back your way.
Your know-how, ready for your AI.
A generic AI gives everyone the same answer. Your Callstand teaches it the calls you'd make: what to do first, what to skip, and how the finished work should look. One account holds your own Callstand and every Callstand people share with you.
Areas
The things you know well, like "Cold email" or "SEO content". Up to five, each described in your own words.
Calibrations
Callstand writes realistic requests and an AI answers them. You say what's off and what you'd do instead. That's how it learns your way.
Your own material
Optional extras that sharpen it: the rules you follow, real examples of past work, and answers to questions you get asked a lot.
From empty to in your AI, usually in an afternoon.
Create your Callstand
Give it a name and add an area. Describe what that area covers. That's the whole first step.
Calibrate it
Generate a test case, read the answer, and write what you'd change. Ten per area gets it ready, and you can keep going to keep improving it.
Test it
Try a real request and see a generic AI's answer next to your Callstand's, side by side. Anything off becomes another calibration.
Publish
One click and it's live. Edits stay in a draft until you publish again, so what you use every day never changes by accident.
Connect it
Add Callstand to Claude, ChatGPT, Cursor or any MCP app once, or use your API key in your own tools.
Share it
Send your link to teammates. They request access, you approve, and your Callstand shows up in their AI too.
Plan it. Make it. Check it.
Your AI picks the right one for what you asked. You don't have to name it.
Tell me what to do, in order
A prioritized plan: what to do first, what to skip, and why.
Do it the way I would
The finished piece, ready to use: the email, the outline, the brief.
Tell me what's wrong first
Paste your work and get what to fix, what's fine, and what to stop worrying about.
Inside the tools you already use.
Claude and ChatGPT
Add Callstand once with one link. Then ask in the chat you already use, and your AI checks your Callstands on its own.
Claude Code, Cursor and Codex
Paste the same link and your API key into the app's MCP settings. No sign-in page needed.
Your own tools
Call any Callstand you can use over a simple API from n8n, Zapier, scripts or your own product.
Your team, and the people you trust.
- Share yours with a link. Teammates open it, sign in, and ask for access. You approve each person, or let anyone with the link in.
- Use theirs next to yours. Paste a teammate's or an expert's link in your dashboard and request access. Once approved, it shows up in your AI alongside your own.
- See who uses it. Your dashboard lists everyone with access and how often they've used it.
- Remove anyone, any time. One click and their tools stop reaching your Callstand right away.
Simple numbers. No subscription.
- $0.50 per call, on any Callstand, whether it's yours or one shared with you. Calls come out of prepaid credits (50 credits each).
- $5 in credits to start, so you can connect your AI and try it right away.
- Building starts free. Every account gets 60 calibration test cases and 10 side-by-side tests free, enough to build a full Callstand. After that, a test case costs 2 credits and a test costs the same as a call.
- Everyone pays for their own calls. When a teammate uses your Callstand, it comes out of their credits, not yours.
You stay in charge.
- Nobody gets access by default. Only you, and the people you approve.
- Your material stays yours. People get answers, never your notes, examples or calibrations, and your Callstand won't reveal them if asked.
- Pause it whenever you want. Every call stops instantly, and resumes just as fast.
- Honest when it doesn't know. Ask about something outside your areas and it says so instead of guessing.
Questions
Is this just a chatbot with my name on it?
No. It answers from what you taught it: the calibrations you wrote, the rules you follow and the examples you added. You can test it against a generic AI side by side and see the difference before you publish.
Do I need to code?
No. You set it up by describing your areas and saying what you'd change in example answers. The API is there if you want it, not required.
Which AI apps does it work with?
Claude, ChatGPT, Cursor, Claude Code, Codex and any app that supports MCP. On ChatGPT Plus and Pro, OpenAI currently limits custom apps to read-only actions; Business and Enterprise workspaces can use everything.
Who pays when a teammate uses my Callstand?
They do, from their own credits. Using your own Callstand comes out of yours.
Can I charge people for using my Callstand?
Callstand doesn't handle payments between people. Everyone pays Callstand the same $0.50 per call, and you decide who gets access.
How many Callstands can I have?
One of your own per account, with up to five areas, plus as many as people share with you.
What happens when I run out of credits?
Calls stop with a clear "add credits" message, and nothing is charged. Top up from your dashboard and you're back.
