No more juggling five apps. EVC brings your models, your code and your automations together.
Sign in with your Anthropic, OpenAI, xAI, Moonshot or Meta account, add a Z.ai or DeepSeek key, or use OpenCode without an account. MTPLX runs models right on your Mac.
EVC reads your project, edits files, runs the tests and commits. Every command, diff and line of reasoning stays visible in the conversation.
Open up to three sessions as columns, each with its own project and model. Claude fixes the front end while GPT sorts out the API and Grok debugs the iOS app.
Schedule a recurring task: EVC runs it on time, on the project and model you picked, then flags what needs your attention.
EVC remembers your preferences and the useful facts of each project, from one session to the next. You stay in control: every memory can be read, edited or deleted.
Skills, agents, commands, rules, hooks, output styles and MCP servers: create your own or turn on the built-in ones, project by project.
Sessions, tool calls and tokens per model, day after day, with a calendar of your activity.
iPhone & iPad
Start a session from the couch, approve an action on the train, review the result on iPad. EVC runs on your machine, whether a Mac, a Windows PC or a Linux server; the phone is just the remote.

Away from home, your iPhone reaches EVC through Tailscale.

FAQ
A “large language model”: the intelligence behind ChatGPT, Claude or Grok. EVC lets you use all of them in one app.
Those from Anthropic (Claude), OpenAI (GPT), xAI (Grok), Moonshot (Kimi), Z.ai (GLM), DeepSeek and Meta, OpenCode's free models, and the ones MTPLX runs on your Mac.
With MTPLX, nothing leaves your machine. With an online model (Claude, GPT…), your messages go to that provider, just like in its official app. EVC never stores your conversations on our servers. It only sends technical and usage statistics, with no content at all (details on the Privacy page).
You use your own accounts or keys. MTPLX is free, you just need a powerful enough Mac.
Install the iPhone app and scan the QR code EVC shows on your machine, whether it's a Mac, a PC or a server. At home it goes over your network; elsewhere, through Tailscale, which encrypts the connection.
EVC is in private beta. The invite code activates your copy of the app on your machine.
Yes. Windows has its own app. On Linux, EVC installs from the command line and you drive it from your iPhone, iPad or the Mac app.
