Handles text,\nimages (GPT-4o vision), and voice notes (OpenAI Whisper). Toxic / spam\ncomments are auto-deleted. Optional Supabase knowledge base lets the AI\nanswer from your documents instead of just the system prompt.\n\nAI agent receives the last 20 messages of conversation history\nautomatically - no memory configuration needed.\n\n### Credentials checklist\n- OpenAI API -> 4 chat models, 4 embeddings (optional, see below),\n 1 moderation, 1 vision, 1 Whisper\n- Nashir API -> 4 Reply nodes, 2 Delete Comment nodes, 4 Get History nodes\n- Supabase API -> 4 Knowledge Base nodes (OPTIONAL - leave unconfigured\n to run without the knowledge base)\n\n### Step 1 - Import this workflow\nn8n -> Workflows -> Import from File -> select the .json you downloaded.\n\n### Step 2 - Add the OpenAI credential\nOpen any of the 'OpenAI:' nodes -> Credentials -> Create New -> paste\nyour OpenAI API key. Reuse for the moderation / vision / whisper nodes.\n\n### Step 3 - Add the Nashir credential\nGet your key at: nashir.ai -> Settings -> API Keys.\nOpen any 'Nashir:' or 'Get History:' node -> Credentials -> Create New\n-> paste the key. Reuse across all Nashir nodes.\n\n### Step 4 - (Optional) Knowledge base\nIf you want the AI to answer from your own documents:\n 1. Create a Supabase project (free tier is fine)\n 2. Run the supabase-schema-setup.sql from the template page in your\n Supabase SQL editor\n 3. Open any 'KB:' node -> Credentials -> Create New -> paste your\n Supabase project URL + service_role key\n 4. Populate knowledge_chunks with your content\nIf you skip this step, the AI runs without the knowledge tool - it answers\nfrom your system prompt alone.\n\n### Step 5 - Copy the production webhook URL\nFrom the Webhook trigger node, copy the URL that does NOT end in '-test'.\nFormat: https://your-n8n.com/webhook/nashir-ai-reply\n\n### Step 6 - Connect to nashir.ai\nnashir.ai -> Chatbot -> Custom Integration -> paste the webhook URL,\nsave, enable the toggle.\n\n### Step 7 - Activate and test\nToggle this workflow ON in n8n. Send a test DM (text, image, or voice)\nto your connected Page or IG account. Check the Executions tab.\n" }, "typeVersion": 1 }, { "id": "sticky-mm", "name": "1.
