What are credits and how are they used?

Credits are the unit of consumption for Fowel's review service. The cost scales with the size (complexity and volume) of the documentation changes in a pull request. This means a small README edit will use few credits and stay cheap, while a large overhaul of multiple API reference files will consume more credits. This model ensures you pay for the actual review work done.

What does the Free plan include?

The Free plan is designed for evaluation. It provides a one-time allocation of 20 credits that you can use to test Fowel on real pull requests in your repositories. It includes both automatic and manual review triggers and supports an unlimited number of repositories.

How does Fowel integrate into my workflow?

Fowel integrates as a GitHub App. You install it to your repository or organization with one click. Once installed, it automatically runs whenever a pull request is opened or updated that contains changes to documentation files (like Markdown or MDX). It posts its review comments directly on the PR, requiring no configuration files or changes to your CI/CD pipeline.

What specific factors does Fowel review in documentation?

Based on expert knowledge, Fowel reviews over 20 factors across several categories: Content Accuracy (outdated info, contradictions), Developer Journey (onboarding flow), Structure & Information Architecture (navigation, naming), Code Samples (runnability, syntax), Clarity & Style (jargon, ambiguous language), and Completeness (existence of tutorials, guides, references).

What file formats does Fowel support?

The page states that Fowel automatically detects Markdown and MDX files for review. It is designed for the documentation files commonly stored in software repositories.

How does the pricing work? Do credits expire?

Fowel uses a subscription and credit-pack model. Paid monthly plans (Pro, Max) come with a recurring allotment of credits (100 and 350 respectively). Credits from the monthly subscription do not roll over. However, you can purchase additional Extension Packs (10 credits for $15). Credits from these Extension Packs never expire and are available for active Pro/Max subscribers to manage busier periods.

How can I buy more credits (Extension Pack)?

Extension Packs can be purchased by active subscribers on the Pro or Max plans. You can adjust the quantity directly during the Stripe Checkout process. To buy an Extension Pack, you must be an active paid subscriber.

Fowel AI: Automated Documentation Review for GitHub Pull Requests

Fowel Overview

Fowel is an AI-powered GitHub application designed specifically to automate the quality assurance of documentation within the software development workflow. By integrating directly into the pull request (PR) process, it acts as a dedicated reviewer for all documentation changes, ensuring that docs are accurate, clear, and useful before they are merged and shipped. It analyzes content based on principles from expert technical writers, covering a comprehensive range of potential issues that traditional code review tools miss.

How to use Fowel

Using Fowel involves a straightforward three-step process integrated into your existing GitHub workflow. First, install the Fowel GitHub App to your repository or organization with a single click; no configuration files, CI changes, or setup scripts are required. Second, simply open a pull request that contains changes to documentation files (like Markdown or MDX). Fowel automatically detects these files. Third, within seconds, Fowel posts a detailed review directly on the PR. This review includes inline comments highlighting specific issues and a summary report, allowing developers to fix problems immediately.

Core Features of Fowel

Automated PR Reviews: Automatically reviews documentation in every GitHub pull request, triggered by changes to Markdown, MDX, and other doc files.
Comprehensive Quality Audit: Checks over 20 factors of documentation quality, including content accuracy, developer journey, structure & information architecture, code sample runnability, clarity & style, and completeness.
Inline Comments & Summaries: Provides specific, actionable feedback directly on the PR in the form of inline comments and a summary review.
Zero-Configuration Setup: Installs in 30 seconds as a GitHub App with no need for config files or CI pipeline modifications.
Credit-Based Scaling: Pricing scales with PR size, making small README updates cheap while larger doc overhauls consume more credits. All plans support unlimited repositories.

Use Cases for Fowel

Fowel is essential for any team that maintains API references, SDK documentation, internal wikis, or user guides directly in code repositories. It is particularly valuable for technical writing teams aiming to enforce quality standards, open-source projects seeking to improve contributor documentation, and engineering organizations where poor documentation leads to increased support costs, developer frustration, or failed AI agent integrations (RAG pipelines). It ensures documentation keeps pace with rapid code changes.

Advantages of Fowel

Fowel offers significant advantages over manual documentation review. It drastically reduces documentation review time by 80%, providing consistent, instant feedback 24/7. It prevents silent revenue killers like unclear API docs that cause developer abandonment, broken code samples that destroy trust, and vague references that cause AI agents to hallucinate. By catching issues early, it reduces support ticket volume and improves the overall developer experience. Its credit-based model is cost-effective, charging for actual review work rather than per seat or repository.

Pricing and Plans

Fowel offers a tiered, credit-based pricing model. The Free plan ($0) provides 20 one-time credits for evaluation, supporting auto & manual reviews and unlimited repositories. The Pro plan ($49/month) includes 100 credits per month and is recommended for growing teams reviewing docs weekly. The Max plan ($129/month) offers 350 credits per month for high-volume organizations. An Extension Pack ($15 per pack of 10 credits) is available for active Pro and Max subscribers to purchase extra, non-expiring credits during busy periods. Larger PRs consume more credits.
