Sending invoices, tracking who's paid, and setting up recurring billing is a small but recurring chore for freelancers and small service businesses — enough of a chore that most people either overpay for accounting software they barely use or scrape by with a plain document template. InvoiceCave is a lightweight invoicing tool built for that gap: create invoices, accept payments through Stripe, track expenses, and manage a client portal, all with a genuinely usable free tier rather than a time-limited trial. Its standout feature is an AI chat interface — you can create an invoice or check payment status by describing what you want in plain language rather than filling out a form — plus direct integration with Claude and other AI coding tools via the MCP protocol, which is unusual positioning for an invoicing product and signals it's built with developer/AI-power-user workflows in mind. The free plan covers 3 customers and 5 invoices a month; the $4/month Pro plan raises that to 200 customers and 300 invoices with fuller accounting features, team members, and API access, and an Enterprise tier adds dedicated infrastructure and SLAs. It supports 30+ currencies and targets freelancers, consultants, and small agencies.

A free, open-source memory system for AI agents that remembers things the same reproducible way every time — instead of the usual approach where an agent's memory changes slightly each time it searches, which makes its behavior hard to trust or audit.
An AI inference API built specifically for speed — over 1,000 image, video, audio and language models served through one endpoint with sub-1-second latency and no cold starts.
