Why ReadMe is not a general help center
ReadMe is a strong API documentation platform. But if your customers are not developers reading OpenAPI specs, you need a help center built for everyday users: searchable articles, AI answers, and a widget in your product.
ReadMe is built for developer documentation
ReadMe is designed around API references, code samples, and OpenAPI/Swagger imports. If your customers are business users, marketers, or non-technical teams, they need how-to articles and FAQ pages, not endpoint documentation.
Pricing jumps fast
ReadMe Starter is $79/month for basic docs. Business with AI features is $499/month. Helpable Pro is $79/month with AI answers, unlimited team members, and a customer-facing help center. You get Calli AI included, not as a $420 upgrade.
No embeddable widget for support
ReadMe does not offer a floating help widget for your product. Helpable gives you a widget with one script tag. Customers search articles and ask Calli questions without leaving the page.
No contact inbox or escalation
ReadMe is documentation, not support. There is no built-in contact form, no inbox, and no escalation path when a customer cannot find an answer. Helpable includes a contact inbox with full AI conversation context attached to every submission.

When ReadMe is the right choice
If you are building developer-facing API documentation with interactive code samples, request/response explorers, and OpenAPI spec imports, ReadMe is purpose-built for that use case. Helpable is not an API doc tool.
When Helpable is the right choice
If your customers are not developers, or you need a general help center alongside your API docs, Helpable delivers AI answers, SEO, a widget, and a contact inbox at a fraction of ReadMe Business pricing. Many teams use ReadMe for API docs and Helpable for everything else.
ReadMe pricing vs Helpable: what you actually pay.
ReadMe Starter is $79/month for basic API documentation. Business is $499/month and includes AI features. Helpable Starter is $29/month with 2,500 Calli AI answers included. Pro is $79/month with 10,000 AI answers and unlimited team members. If you need both API docs and a help center, Helpable Pro plus ReadMe Starter ($158/month combined) costs less than ReadMe Business alone.

Contact inbox with context

“We kept ReadMe for our API reference but added Helpable for everything else: onboarding guides, billing FAQs, troubleshooting. Calli handles 40% of customer questions now.”
Ryan D., Head of Developer Relations, Apitrace (API monitoring platform)
“ReadMe is fantastic for our developer docs, but our non-technical customers were lost. Helpable gave them a proper help center with AI search. Support tickets from business users dropped by half.”
Priya N., Support Lead, Linkforge (Link management SaaS)
Is ReadMe a customer help center?
ReadMe is primarily an API documentation platform. It excels at developer-facing reference docs with code samples and request explorers. For general customer help with how-to articles, FAQs, and AI self-service, Helpable is the better fit.
Can I use both ReadMe and Helpable?
Yes. Many teams use ReadMe for API reference documentation and Helpable for general customer support articles. They serve different audiences and work well together.
How does Helpable pricing compare to ReadMe?
ReadMe Starter is $79/month, Business is $499/month (includes AI). Helpable Starter is $29/month with AI included, Pro is $79/month with unlimited team members. Helpable includes AI on every plan, not as a premium tier upgrade.
Does Helpable support API documentation?
Helpable is a general-purpose help center, not an API documentation tool. You can write guides about your API, but it does not import OpenAPI specs or render interactive endpoint explorers. For that, use ReadMe alongside Helpable.
Will my articles be found by ChatGPT and Perplexity?
Yes. Helpable generates FAQPage, HowTo, Article, and BreadcrumbList structured data on every article. Combined with sitemaps, hreflang, and custom domain support, your content is visible to AI-powered search tools.
