If you're looking for something to replace LaunchBrightly, WorkStreamer Guide could be a good option. The service can help you create training materials by taking screenshots automatically with a Chrome extension. It's geared specifically for creating user guides, with features to update text and styling, blur private information and export guides in different formats. Pricing starts at $20 per month for the Pro plan, so it's relatively affordable.
Another option you might want to consider is HelpLook. The service can help businesses build a help center site with FAQs, user guides and troubleshooting sections. It's got features like search engine optimization (SEO), a knowledge base portal and AI-powered support for common questions. HelpLook's goal is to help reduce the support burden and increase self-service, which dovetails with the idea of keeping your help center fresh and consistent. Pricing ranges from free to $29/month for the Professional plan.
