  • Catch overlap across ChatGPT, Claude, and Cursor

Built for the tools builders actually pay for

Track ChatGPT, Claude Code, Cursor, Copilot, Windsurf, Gemini, Devin, Zed, Replit, Bolt, Lovable, v0, Supabase, Vercel, Midjourney, Figma AI, Notion AI, and the tools you add yourself.

Import your stack your way

Start manually, paste invoice text, or upload screenshots for AI parsing. You do not need finance-grade setup to get value.

Self-serve by design

No approvals, no procurement workflow, and no enterprise admin layer between you and your stack decisions.

Recommended tool

Use SubHorizon with Windsurf when your stack still needs a dedicated IDE.

Track Windsurf in SubHorizon, then jump straight into the IDE if it is still the right fit for your stack.

The Root Problem

AI tool sprawl is normal. Paying blindly for it is not.

Builders rarely have a procurement system. They have receipts, scattered invoices, and a stack that mutates every month.

IDX_01

Stop bleeding money on overlap.

Paying for ChatGPT, Claude Code, Cursor, and Windsurf simultaneously? That is redundant logic. Catch duplicate spend before the next invoice.

IDX_02

Surprise charges destroy margins.

Monthly, annual, and credit-based plans live in different silos. Unify them into a single timeline to predict cash flow.

IDX_03

Context decays, subscriptions remain.

You start a trial for a prototype and forget it exists. Stop paying for yesterday's abandoned experiments.

The Workflow

A command center for your recurring AI spend.

Ingest your subscriptions, analyze overlap automatically, and execute cancellations before the next billing cycle.

STEP_01

Ingest your stack

Upload screenshots, paste invoice text, or add manually. Zero integration required.

STEP_02

Analyze overlap

Instantly identify redundant tools and pinpoint exactly where you are overpaying.

STEP_03

Execute cuts

Set notes, plan cancellation dates, and kill zombie subscriptions before they auto-renew.

Unified visibility

Monitor every AI subscription in a single view.

A consolidated dashboard for the tools you actively leverage, the ones requiring review, and those creating redundant capabilities.

Actionable intelligence

Identify financial waste automatically.

SubHorizon detects stack inefficiencies and flags redundant subscriptions where one tool provides the capabilities of two.

Inefficiency flagged

Review overlap before the next renewal.

Simultaneous subscriptions to ChatGPT, Claude, and Cursor detected. Evaluate which isolated models are strictly necessary for your current workflow.

POTENTIAL_WASTE: $240/year
ChatGPT and Claude both provide general LLM interfaces
Cursor natively integrates leading models into your IDE
Annual renewals require explicit review prior to execution
Preserve context

Document your cancellation rationale.

Attach context to subscriptions so you remember exactly why a tool was retained or scheduled for termination.

Frequently Asked Questions

Everything here is aimed at reducing friction for self-paying AI builders, not pushing them into a heavy setup.

KNOWLEDGE_BASE_v2.0
QUERY://Can I track AI tools manually?
RETURN://

Yes. Manual entry is a first-class workflow. You can start with the tool name, price, renewal date, and billing interval, then refine from there.

QUERY://Do I need to connect a bank account?
RETURN://

No. SubHorizon is meant to work without bank login. Builders can get value immediately from manual entry, pasted text, screenshots, and CSV imports.

QUERY://What if I pay in different currencies?
RETURN://

SubHorizon supports multi-currency tracking so you can see a mixed AI stack in one preferred home currency.

QUERY://Can I track annual renewals and trials?
RETURN://

Yes. Annual renewals, monthly subscriptions, and trials all belong on the same timeline because they compete for the same budget.

QUERY://Is this only for solo builders?
RETURN://

The landing page is optimized for self-paying builders, but the product also works for freelancers and small teams that need shared visibility without enterprise overhead.

QUERY://What kinds of tools fit best?
RETURN://

AI coding tools, model subscriptions, design assistants, and recurring creative tools fit especially well because the renewal cadence is frequent and the overlap risk is high.

QUERY://What is a vibe coding stack and why should I track it?
RETURN://

A vibe coding stack is the collection of AI tools you use to build software — Cursor, Claude Code, ChatGPT, Copilot, Windsurf, Gemini, and others. Tracking it matters because these subscriptions add up fast, overlap often, and renew on different cycles. SubHorizon gives you one place to see what you pay for and what to cut.
