Your First Session

What Happens When You Run fai

You run:

$ fai

You see:

Fathym AI
─────────
Your workbench is ready.
Let's build something.

That's it. No setup wizard. No configuration. No API key prompts. Your AI is ready.

Your First Conversation

You: I'm building a REST API for a recipe app
AI:  Great. What framework do you prefer?
You: Whatever you think works best
AI:  I'll use FathymAPI - it's lightweight and fast for Deno.
     Starting with the recipe CRUD endpoints.
     [Generates project structure + initial routes]

Notice what happened:

  • You described WHAT you wanted
  • Your AI handled HOW
  • No boilerplate. No scaffolding commands. No decisions you didn't need to make.

Behind the Scenes

While you were building, your workbench was working too:

  • Saved your framework choice (FathymAPI) - won't ask again
  • Noted your style (concise instructions, trust AI's judgement)
  • Recorded the project context (recipe API, Deno runtime)

You didn't tell it to do any of this. It's automatic.

Where fai Makes the Difference

Your first session is roughly the same with any AI tool - you start building.

What changes is every session after the first.

Without fai (Session 2):

You: I'm working on that recipe API we started yesterday
AI:  What recipe API? Can you describe the project?
You: We're using FathymAPI, Deno, and I have 4 endpoints...
AI:  Got it. What patterns are you following?
You: [20 minutes of re-explaining]

With fai (Session 2):

$ fai

  Welcome back. Picking up where you left off.
  Your recipe API has 4 endpoints. Ready to add authentication?

<3 seconds. Full context restored. No re-explaining.

That gap widens every session. By Session 50, your AI anticipates your needs. Without fai, you're still re-explaining on Session 50.

See What Your AI Knows

After any session, open a second terminal:

$ fai --preview

This opens MCP Inspector in your browser. You can see every tool your AI can call, every piece of context fai captured, and the full project knowledge fai has built. Browse entries, call tools yourself, and verify exactly what your AI reads before it writes a single line.

After Your First Session

Tomorrow, you type fai again. No re-explaining. Your AI picks up exactly where you left off. That's the difference.
