<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>anotherpaulg</author><text>You could try using aider [0], which is my open source ai coding tool. You need an OpenAI API key, and aider supports any of the GPT 3.5 or 4 models. Aider has features that make it work well with existing code bases, like git integration and a &amp;quot;repository map&amp;quot;. The repo map is used to send GPT-4 a distilled map of your code base, focused specifically on the coding task at hand [1]. This provides useful context so that GPT can understand the relevant parts of the larger code base when making a specific change.&lt;p&gt;[0] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;paul-gauthier&amp;#x2F;aider&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;paul-gauthier&amp;#x2F;aider&lt;/a&gt;&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;aider.chat&amp;#x2F;docs&amp;#x2F;repomap.html&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;aider.chat&amp;#x2F;docs&amp;#x2F;repomap.html&lt;/a&gt;</text><parent_chain><item><author>rickstanley</author><text>Hello, I would like to take this opportunity and ask for help here, about using A.I. with my own codebase.&lt;p&gt;Context:
