Sharing AI work online is still surprisingly clunky. You screenshot a messy terminal, crop out your credentials, and end up with something that looks like it was captured on a potato. Not exactly slide-deck worthy.
That’s what caught my attention about this one. The author built a slick little browser tool that turns raw agent session transcripts into clean, polished, shareable images.
What agentpng actually does
This Redditor created agentpng specifically to solve the “how do I share this cool agent session” problem. Think of it like those gorgeous code snippet image generators (Carbon, Ray.so, etc.) but built for the messy back-and-forth of agentic AI conversations.
You paste in your transcript, and out comes something presentation-ready.
🧩 Supported sources
The tool isn’t locked to a single ecosystem. The creator built it to handle output from:
- Claude Code — session transcripts
- Cursor — CLI chats
- Kiro — including Kiro specs
- Codex — OpenAI’s coding agent
So if you’re bouncing between tools (which most people are), you’re covered regardless of which agent you were running.
🖼️ Where the output shines
According to the original poster, the generated images work particularly well for:
- Social media posts (X/Twitter, LinkedIn)
- Slide decks and presentations
- Documentation or tutorials
- Any place where you want to show, not just tell, what an agent did
The key thing here is format. Raw CLI output looks like noise to most people. A clean, formatted image communicates the same information in a way that actually lands.
⚡ The workflow in practice
Using agentpng takes maybe 30 seconds:
- 🗂️ Copy your agent session transcript (from CLI output or a saved file)
- 📋 Paste it into agentpng.dev
- 🎨 Get back a styled, shareable image
- 📤 Drop it into your post, deck, or doc
No account, no upload, no backend. It runs entirely in the browser.
Pro tip
If you’re documenting an agentic workflow for a team or client, this is a much better move than screenshotting raw terminal output. The formatted image makes it obvious what the agent did, what tools it used, and how the conversation flowed. Much easier to scan.
What’s worth noting
The tool is both free and open source. The code lives on GitHub under the creator’s account (siegerts), so if you want to self-host it, fork it, or contribute, that’s all on the table. Running it entirely in the browser is a smart privacy call too: your agent transcripts never touch a server.
On the flip side, the post is fairly early-stage with just a couple of upvotes and no community comments yet. There’s no word on whether it handles very long transcripts gracefully, or how much formatting customization is available. Worth testing with your own sessions to see where the edges are.
If you’ve used Carbon or Ray.so for code snippets before, this takes the exact same idea and applies it specifically to the agent-chat format. It fills a gap that’s been quietly annoying anyone who shares AI dev work publicly.
