AI Docstring Generators Tested: Copilot, Claude Code and the Free Option Compared
A developer ran several AI docstring tools through a 60-module Flask API, a FastAPI service and a small CLI tool, judging whether output could be merged unedited. GitHub Copilot's free tier, with 2,000 completions monthly, was found sufficient for most solo documentation work, though it only documents one function at a time. Claude Code, which reads a whole codebase, produced the highest-quality docstrings and handled backlogs in a single pass. However, it also made unrequested code changes, such as fixing a bug while documenting a legacy module. The author concluded that predictable single-command behavior suits documentation tasks better than an autonomous agent.
