A tool built for independents and small teams who want to move fast without sacrificing quality.
Know exactly which deal to close next. Build a visual pipeline, send proposals in one click, and never miss a follow-up again.
Get paid faster. Create professional PDF invoices in 2 clicks, track overdue payments automatically and manage multiple bank accounts.
See every project at a glance. Kanban board, dated milestones and file attachments — all linked to your client and invoice.
Stop the back-and-forth emails. Give clients a branded portal to view projects, chat in real time and access their invoices — all in one place.
Everything connected — that's the point
Your data flows between modules automatically. A lead converts to a client, a client gets invoiced, invoices link to projects, projects feed your analytics. No copy-pasting, no CSV imports — one source of truth.
Plus: Notes, Email Marketing, Mindmaps, Calendar sync, Cloud Storage, Analytics, and more.
A single workspace to run every part of your business, from lead to invoice. No more tab-switching or stacking subscriptions.

vs. paying for each tool separately
Krolyx ships with a Model Context Protocol server, embedded agents and native RAG. Your data, your tools, ready for Claude — and any agent that follows.
Install the Krolyx MCP server and your AI suddenly speaks fluent CRM, invoicing and projects. Read, write, automate — under your auth, your permissions.
Krolyx runs natively on macOS and Windows — same workspace, same permissions, faster shortcuts and offline-friendly drafts.
Native AI flows triggered from any record. Draft proposals, qualify leads, summarise threads — with the context already in your workspace.
Notes, proposals, invoices, threads — all chunked, embedded and ready to power answers grounded in your reality.
And they don't talk to each other. KROLYX replaces them for far less — all your data in one place, talking to itself.

I was juggling 7 tools to manage 12 clients. Half my day went into copy-pasting data and apologising to clients I forgot to follow up. KROLYX is the tool I wished I had. Dozens of others use it now — I'd be glad to count you among them.
