Captiongen

What is Captiongen?
Captiongen is a lightweight social media caption generator that turns a short description of your post into ready-to-paste text. You describe what the image or update is about, pick a tone, and the site sends that prompt through OpenAI's API to draft a caption. The live app at captiongen.stanleyzhao.com runs as a simple two-step form with no signup wall.
Most caption apps bundle scheduling, analytics, or hashtag research. Captiongen skips all of that and stays a single-purpose demo you can run in a browser or clone from GitHub. You supply your own OpenAI API key, so usage cost follows OpenAI's token pricing rather than a separate Captiongen subscription. The project is a fork of @nutlope's twitterBio template, adapted for Instagram-style captions instead of bios.
It fits social media managers, creators, and anyone who knows what they want to say but stalls on the actual line. The Funny style preset on the homepage targets lighthearted Instagram posts, while developers can deploy the Next.js source locally with npm, yarn, or pnpm.
Predis

What is Predis?
Predis turns product links, images, or short text prompts into platform-ready ads, UGC-style videos, and carousel posts for social channels. Pick Instagram, TikTok, LinkedIn, or Pinterest, generate creatives with its ad generator, then schedule and publish from one content calendar with brand kits and team approvals.
Canva-style editors make every post from scratch. Predis bundles generative ad images, video ads with voiceovers, competitor analysis runs, and auto-posting on higher tiers so agencies can manage multiple brands without juggling five tools. Customer stories on the site cite roughly 3X higher CTR on AI-generated ads and a 75 percent reduction in production hours.
Solo sellers start on Core with 1,300 monthly credits (about 86 AI images or 9 videos). Agencies pick Rise for four brands and auto-posting across 20 channels. Enterprise+ adds 10,000 credits, unlimited brands, and 600 competitor runs per month. A 7-day free trial covers the full workflow before you pick a paid plan.
