Mehtagent Lite

Mehtagent Lite is a small Mac app that runs your AI for you, whether that is Claude, Codex, Gemini or one of hundreds of other models. You tell it what you want to make and it starts your AI in the right folder. Then it shows the work as a conversation between you and the AI, with the files it made listed beside it.

We built Lite at SimPPL as a smaller view of Mehtagent, the app we use every day to run Claude Code. Everything Lite does, the full version also does. Lite shows less of it at once and uses plainer words.

What you can do with it

Ask for something. The Home page has one box. Write "a one-page site for my bakery" or "a proposal for this funding call", press Start, and choose the folder (Lite suggests one and says why), and Claude starts there. If Claude stops to ask you something, a card on Home says so, with Answer and Done.

Follow the work. Each conversation shows your messages and Claude's replies. Between them is one short line for each batch of steps, such as "looked at 3 files · wrote index.html", and a click on it shows the steps themselves. In the panel beside it you see the files Claude made and the pages it looked up. You can add files with the + button, by dropping them on the page, or by pasting an image.

Answer Claude's questions. When Claude asks permission before it changes a file, Lite shows the same question as a card, with a button for each choice. It waits for your click before it answers Claude.

Funding. This is one place for your proposals and their deadlines and for the people you're meeting next, with what to ask them. It also keeps drafts of the outreach emails you plan to send, ready for you to edit. There is a box where you describe your work, and Claude looks for open funding calls that fit it.

Ship. Put a website or small tool online with Vercel. Lite walks you through three set-up steps and then makes a preview, which gets its own vercel.app address so you can check the site before anyone else sees it. When you click Put this version live, Lite makes that exact preview the live site.

Keys, in one place. Claude uses your Claude account, so it needs no key. Mehtagent uses an OpenRouter key, if you add one, to write short summaries of your conversations and for a few small helper tasks. You paste that key once into Setup, and after that Setup shows how long ago you added it and keeps the key itself hidden. You can also set a spending cap, and Lite stops using OpenRouter once the last seven days of spending reach it.

What you need

Install

  1. Download the newest Mehtagent-Lite disk image from this project's page on GitHub, under Releases.
  2. Open it and drag Mehtagent Lite onto Applications.
  3. Before you open Mehtagent the first time, open Terminal and run xcode-select --install. If a window offers to install the command line developer tools, click Install and wait for it to finish. If Terminal says they are already installed, go on to the next step.
  4. Open Mehtagent Lite from your Applications folder. This early build isn't notarized by Apple yet, so the first time macOS may say it can't check the app. If it does, open System Settings, then Privacy & Security, and click Open Anyway.
  5. A small diamond appears in the menu bar and the dashboard opens in a window. The first time, Setup asks where your projects live, and that's the first thing to answer before you start.

The tutorial in TUTORIAL.md walks through your first request, from the Home box to a preview link.

Where your work goes

Your conversations, settings and keys are stored on your Mac. Your keys are kept in files that only your user account can read. Some things do leave the Mac, as they would without Lite. What you ask Claude goes to Anthropic, and a site you preview or put live goes to Vercel. If you've added an OpenRouter key, the text Mehtagent summarises goes to OpenRouter. Once a day the app sends your code and a hashed id for your Mac to SimPPL's licence server. If you agree to share usage, it also sends counts, such as how many conversations you had, and never what you wrote.

Moving to the full version

Lite shows the simple view only. The full version adds the terminals, the watchdog (which nudges Claude when a long task stalls), usage records and backup sync. It needs a licence: reply to your invitation to ask for one. Once it is on, Setup's View row switches between the two, and your folders, conversations and settings stay where they were.
