Chat.sh

About Chat.sh

Chat.sh is a knowledge base tool that places a help center in a folder on your own domain, such as yoursite.com/help, rather than on a separate subdomain. It uses AI search to read a question and write an answer with citations linking back to the source articles. The tool also stores every page as markdown, making content accessible to ChatGPT, Claude, and other systems via llms.txt.

Review

Chat.sh was built by Damon Chen after encountering keyword search limitations in Intercom's help center. The product launched with a live implementation at testimonial.to/guide, where the maker's own help center now runs. It's positioned as a one-time purchase with no subscription, which differs from most help center tools that charge monthly.

Key Features

• AI search that reads the question, writes an answer, and links to the articles it used as sources
• Help center lives at a path on your own domain (yoursite.com/help) instead of a subdomain
• Readable URLs and preview cards for every article when shared
• Every page can be copied as markdown or opened directly in ChatGPT or Claude
• llms.txt file that indexes every article URL for AI agents

Pricing and Value

Chat.sh uses a pay-once model with two tiers at launch. The $399 tier includes 1,000 AI credits per month, 3 teammates, and 3 inbox seats. The $799 tier includes 5,000 AI credits per month, 5 teammates, and 5 inbox seats. A launch discount code (PHLAUNCH) reduces these to $199 and $599 until October 2 at 12 AM PT. The maker has stated the price will increase by $100 each time a new component ships, and buyers who purchase now will receive the planned chat messenger and support inbox without paying again. How the tool handles monthly AI credit caps during traffic spikes has not been clarified in the launch materials.

Pros

• AI search cites the specific articles it drew answers from, which helps users verify information
• Content remains exportable as markdown files at any time via a simple wget loop
• The rewrite rule for routing /help lives in your own infrastructure, so you can repoint or remove it without contacting the vendor
• One-time payment replaces recurring subscription costs found in many help center tools
• Every article URL stays on your domain, which preserves links and search rankings if you migrate away

Cons

• The help center runs through a reverse proxy to Chat.sh servers, not as static files in your repo, so uptime depends on the vendor's infrastructure
• Monthly AI credit limits are fixed at 1,000 or 5,000, and the behavior when credits run out mid-month has not been documented
• Teams needing a chat messenger or support inbox right now won't find those features here yet; they are listed as upcoming, not shipped

Chat.sh suits small teams and solo makers who want a help center on their own domain without a monthly bill and who are comfortable with markdown-based content workflows. It's less appropriate for organizations that require static file ownership in their own repository or need a support inbox and in-app chat messenger today. The reverse proxy architecture means the tool's long-term availability depends on Chat.sh remaining operational, though the markdown export path reduces content lock-in risk.
