Export to a self-hosted HTML site, Markdown for your docs site, or both

What you get

AI-written prose for every endpoint, request body, and response shape
Working curl examples with realistic sample payloads
Parameter tables with descriptions auto-generated from schema
Error code reference with likely causes and fixes
Clean static HTML output (host anywhere)
Markdown output for Docusaurus / Mintlify / GitBook / your own static site
Supports OpenAPI 2.0 and 3.0, JSON or YAML

Pricing

Free — 1 generation per month, full feature set
Pro — $19 / month (₹1,599 in India) — unlimited generations, specs up to 10 MB

Best for

API teams who hate writing docs but ship endpoints constantly
Indie hackers who want documentation-as-marketing for a launching API
Internal tools teams documenting APIs for partners or other teams
Anyone migrating off ReadMe, Stoplight, Mintlify, or Apidog and looking for a one-shot AI generator instead of a CMS

Built and operated by an indie founder in Pune, India.

Questions & Answers

As answered by people managing Request inspector and Docsmith.

What makes your product unique?

Docsmith's answer:

Docsmith is the only OpenAPI documentation tool that writes the prose for you. Competing tools (ReadMe, Stoplight, Apidog) give you a polished editor, but you still hand-write every endpoint description, every parameter explanation, every error-code reference. Docsmith reads your OpenAPI 2.0 / 3.0 spec and AI-generates the full content in under 60 seconds — endpoint descriptions, parameter tables, working curl examples, and an error-code reference — then exports clean static HTML or Markdown you self-host. No CMS to maintain, no team subscription, no vendor lock-in.

Why should a person choose your product over its competitors?

Docsmith's answer:

Three reasons.

Speed — a 200-endpoint spec becomes complete documentation in under a minute, versus the days it takes to write manually.
Ownership — output is plain HTML and Markdown you fully own. Host it anywhere, edit it freely, no platform fees if you scale.
Price — Pro is $19/month with unlimited generations. Compare against ReadMe (~$200+/month) or Stoplight (custom enterprise pricing).

Best fit when you want documentation-as-a-deliverable rather than documentation-as-a-CMS.

How would you describe the primary audience of your product?

Docsmith's answer:

Indie API builders and small API teams that ship endpoints faster than they document them. Typical users:

Solo founders launching a SaaS API and needing public docs day-one
Internal-tools teams documenting a service for partner integrations
Open-source maintainers who need current docs at every release

The common pattern: a working OpenAPI spec already exists, the team cares about good docs, but writing prose for every endpoint is a tax they don't want to pay.

What's the story behind your product?

Docsmith's answer:

Docsmith started after the founder spent two full days writing endpoint descriptions for a 40-route OpenAPI spec — work that an LLM can do in 90 seconds with better consistency.

The first version was a personal CLI script. After a few API teams asked for it, it became a hosted product with email-only auth, two pricing tiers (Free + Pro), and a 60-second turnaround promise.

Built and operated solo by Bikram from Pune, India. Launched April 2026.

Which are the primary technologies used for building your product?

Docsmith's answer:

Frontend: Next.js (App Router), TypeScript, Tailwind CSS
Hosting: Vercel
AI: Anthropic Claude API for the prose generation
Storage: Cloudflare R2 for generated artifacts
Billing: Razorpay (India), Stripe (rest of world)
Bundling: JSZip for the downloadable archives
Auth: Email-only, no SSO

The stack is intentionally boring — the value is in the prompt engineering and the spec parser, not the framework choices.

Who are some of the biggest customers of your product?

Docsmith's answer:

Docsmith launched in April 2026 and is not yet citing production customers by name. Once we have explicit permission from users to feature them as case studies, this section will be updated.
