Can I code Clay?

A personal contact list with notes and reminders to stay in touch is genuinely simple CRUD. Automatically enriching contacts with data pulled from elsewhere and suggesting who to reach out to is where the real depth starts.

Why CanICodeThis says Borderline

  • Contacts with notes, tags, and a 'last contacted' date are ordinary CRUD
  • A reminder to follow up if you haven't spoken to someone in N days is one scheduled email, similar to this register's own reminder patterns
  • For a manually-maintained personal CRM, this is genuinely a weekend build

What you give up building Clay yourself

  • Automatically enriching a contact with their recent job change, social activity, or public info needs real third-party data API integrations, each with their own cost and reliability
  • AI-suggested talking points based on someone's recent activity is a genuine, separate feature beyond storage and reminders
  • Importing and de-duplicating contacts from multiple sources (phone, email, social) is fiddlier than it first appears

How to build your own Clay

Build me a personal CRM: contacts with notes, tags, and a last-contacted date, with an email reminder if you haven't reached out in a set number of days. SQLite behind a small API, single-user login. Skip automatic contact enrichment and AI suggestions for v1 — manual notes are a real, achievable starting point.

What it actually costs to build

Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.

AI agent — with a subscription (Claude Pro/Max, Cursor, etc.)$0 marginal
AI agent — pay-per-use API, no subscription$43–$86 one-time
Hosting, once it's running$0/mo (free tier)
Domain name, if you want your own~$12/yr

Clay costs $149/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 1 month.
