Codex Labs: AI agents, automation, websites and apps
AI agents and automation for teams that have outgrown manual work
Answer calls, reply to enquiries and collect the details your team needs to follow up. We build voice agents, chatbots and connected workflows, plus websites, mobile apps and native macOS apps.
Start with one workflow. Add more as your business needs them.
We also build and run our own products: Synopt, CoolCurve, Preen and Submix.
AI & automation
Help more inquiries become conversations
Start with the part of your day that needs help. We set up the workflow around your business, connect your tools and offer ongoing support.
Missed Call Text Back
When a call is missed, an automatic text goes out. AI carries on the conversation, answers routine questions and collects the job details.
Web Lead Instant Response
Automatically respond to a new website inquiry, answer follow-up questions and collect the details while the customer is still interested.
AI Lead Qualification
AI screens leads against your service area, job types and timing rules, then passes qualified leads and exceptions to your team. No manual screening needed.
AI Voice Agents
Answer overflow or after-hours calls, handle common questions and collect details for a callback.
CRM Automation
Keep contacts, pipeline stages, reminders and follow-up tasks in sync across the tools you use.
AI Chatbots
Answer questions on your website or WhatsApp using your business information, with a handoff to your team.
Appointment Reminders & No-Shows
Automatically confirm bookings and remind customers the day before and a couple of hours before. Stop reminders on cancellation and update them if the booking moves.
Lead Follow-Up Automation
Automatically follow up with leads who received a booking link but haven't booked. Stop as soon as they book, reply or opt out.
Built with tools such as GoHighLevel, n8n and Retell AI. We choose the setup around your existing systems, contact permissions and the work your team needs to do.

Synopt
Endpoint-level observability for enterprise AI tool usage. A lightweight on-device agent captures telemetry from AI coding tools, scans for and redacts secrets at capture time, and ships usage, cost and security analytics to a dashboard, so engineering leaders can see how AI tooling is actually being used without collecting the prompts themselves.

CoolCurve
A native macOS app that gives Apple silicon Macs clear temperature monitoring and safe, precise fan control. Reads every hardware sensor and real fan RPM through the SMC, then replaces firmware-only behaviour with manual speeds, multi-point curves, and per-sensor rules.

Fintrail: AI Finance Tracking
An AI finance tracking app that reads bank SMS to categorize transactions, splits bills between friends, and tracks stock and cryptocurrency portfolios.
