AI Carousel Caption & Template Editor Workflow Overview This workflow is a caption-only carousel text generator built in AlekSystem. It turns any raw LinkedIn post or text input into 3 short, slide-ready title + subtext captions and renders those captions onto image templates. Output is a single aggregated response with markdown image embeds and download links. Workflow Structure Input:** Chat UI trigger accepts text and optional template selection. Core AI:** Agent cleans input and returns structured JSON with 3 caption pairs. Template Rendering:** Edit Image nodes render title and subtext on chosen templates. Storage:** Rendered images uploaded to S3. Aggregate Output:** Aggregate node builds final markdown response with embeds and download links. Chat Trigger (Frontend) Trigger:** When chat message received UI accepts plain text post. allowFileUploads optional for template images. SessionId preserved for context. AI Agent (Core) Node name:** AI Agent Model:** Mistral Cloud Chat Model (mistral-small-latest) Behavior:** Clean input (remove stray formatting like \n and ** but keep emojis). Produce exactly one JSON object with fields: postclean, title1, subtext1, title2, subtext2, title3, subtext3. Titles must be short (max 5 words). Subtext 1 or 2 short sentences, max 7 words per line if possible. Agent must return valid JSON to be parsed by the Structured Output Parser. Structured Output Parser Node name:** Structured Output Parser Validates agent JSON and prevents downstream errors. If parsing fails, stop and surface error. Normalize Title Nodes Nodes:** normalize title,name 1, normalize title,name 2, normalize title,name 3 (and optional 4) Map parsed output into node fields: title, subtext, safeName (safe filename for exports). Template Images Source:** Google Drive template PNGs (download via Google Drive nodes) or provided upload. Keep templates high resolution and consistent aspect ratio. Edit Image Nodes (Render Captions) Nodes:** Edit Image 1, Edit Image2, Edit Image3, Edit Image3 (or Edit Image3/Edit Image4 as available) MultiStep operations render: Title text (font, size, position) Subtext (font, size, position) This is where caption text is added to the template. Upload to S3 Nodes:** S3 Upload rendered images to bucketname using safeName filenames. Confirm public access or use signed URLs. Get S3 URLs and Aggregate Nodes:** get s3 url image 1, get s3 url image 2, get s3 url image 3, get s3 url image 4 Merge + Aggregate:** Merge1 and Aggregate collect image items. Output Format:** output format builds a single markdown message: Inline image embeds `` Download links per image.

Clean the user input (remove stray newlines and markup but keep emojis). Return a single JSON object with postclean, title1/subtext1, title2/subtext2, title3/subtext3. Titles must be short (max 5 words). Subtext should be 1 to 2 short sentences, useful and value adding. Respond only with JSON. Key Features Caption only output: 3 short slide-ready caption pairs. Structured JSON output enforced by a parser for reliability. Renders captions onto image templates using Edit Image nodes. Uploads images to S3 and returns markdown embeds plus download links. Template editable: swap Google Drive background templates or upload your own. Zero guess formatting: agent must produce parseable JSON to avoid downstream failures. Summary A compact AlekSystem workflow that converts raw LinkedIn text into a caption-only carousel with rendered images. It enforces tight caption rules, validates AI JSON, places captions on templates, uploads images, and returns a single ready-to-post markdown payload. Need Help or More Workflows?
