Instagram Caption Generator

Generate engaging Instagram captions with emojis and hashtags for any photo or topic. Use Claude AI to match your brand voice and style.

API Setup Required

AI tools need a backend API route to work. This prevents CORS errors from calling Anthropic directly from the browser.

Quick Setup (3 steps)

Create API route

app/api/ai/route.ts

Add your API key

.env.local → ANTHROPIC_API_KEY=sk-ant-...

Enable in component

AIToolBase.tsx → AI_ENABLED = true

app/api/ai/route.tsCopy & paste

import Anthropic from "@anthropic-ai/sdk";
import { NextRequest, NextResponse } from "next/server";

const client = new Anthropic({
  apiKey: process.env.ANTHROPIC_API_KEY,
});

export async function POST(req: NextRequest) {
  const { system, prompt } = await req.json();
  const msg = await client.messages.create({
    model: "claude-sonnet-4-20250514",
    max_tokens: 1024,
    system,
    messages: [{ role: "user", content: prompt }],
  });
  const text = msg.content[0].type === "text"
    ? msg.content[0].text : "";
  return NextResponse.json({ text });
}
