Onboard AI - AI Code Assistants Tool

Overview

Onboard AI is a lightweight, GPT-powered code-assistant that "turns any GitHub repo into a subject‑matter expert" by cloning a repository and exposing a chat interface you can ask about structure, functionality, and where to make changes. The Product Hunt launch describes it as a quick way for newcomers and maintainers to locate code paths, debug, and generate context-aware suggestions using the repository as the knowledge source. ([producthunt.com](https://www.producthunt.com/posts/onboard-ai)) Operationally, Onboard works by indexing or cloning a target GitHub repository and answering natural‑language queries with repo‑specific context (it advertises GPT under the hood). The makers also highlighted multi‑repo sessions — the ability to add multiple repositories and documentation into a single chat — and a free tier for public repositories (a frequently cited limit is public repos under ~100MB). Note: third‑party monitors have reported the getonboard.dev site as intermittently unavailable, so availability may vary. ([producthunt.com](https://www.producthunt.com/posts/onboard-ai))

Key Features

• Clone and index a GitHub repository for conversational queries about its code. ([producthunt.com](https://www.producthunt.com/posts/onboard-ai))
• GPT-powered chat that answers where functionality lives and how code paths work. ([producthunt.com](https://www.producthunt.com/posts/onboard-ai))
• Multi-repo sessions: combine several repos and docs into one chat context. ([linkedin.com](https://www.linkedin.com/posts/greptile_secure-soc2-compliant-ai-chat-with-any-github-activity-7107495576597848064-cNGr?utm_source=openai))
• Open‑source reference / early code visibility referenced in the product launch. ([producthunt.com](https://www.producthunt.com/posts/onboard-ai))
• Free access for public repositories (historical limit noted around 100MB). ([linkedin.com](https://www.linkedin.com/posts/greptile_secure-soc2-compliant-ai-chat-with-any-github-activity-7107495576597848064-cNGr?utm_source=openai))

Use Cases

• Onboarding new engineers to a large codebase by asking targeted, repo‑aware questions.
• Locating where a particular feature or API call is implemented in a repo.
• Triage: paste an error or describe a bug and ask which files likely contain the root cause.
• Preparing PRs by asking where a change should be made and what tests might cover it.
• Exploring open‑source projects before contributing, without reading the entire codebase.

Pricing

Free: $0

• Use with public GitHub repositories (free tier noted historically for repos <100MB)
• Chat-based repo Q&A powered by GPT
• Open-source project link available from launch notes

Product Hunt and maker posts list Onboard as free (public repos under ~100MB). Official site (getonboard.dev) has been intermittently unreachable; private/repo-based paid tiers were not listed in available sources. Confirm current limits and private‑repo pricing on the product site or contact the team. ([producthunt.com](https://www.producthunt.com/posts/onboard-ai))

Alternatives

• Mutable.ai
• ExplainGithub
• DeepWiki (by Cognition)
• Cursor
• Bito

Onboard focuses on quick, repo‑scoped conversational search and is positioned as a lightweight GPT chat over cloned GitHub repos. Alternatives like Mutable.ai and DeepWiki emphasize persistent AI wikis or knowledge bases; Cursor and Bito provide IDE/PR‑centric coding assistance and generation. Evaluate whether you need an ephemeral chat over a repo (Onboard) versus a long‑term indexed knowledge base or IDE integration. ([producthunt.com](https://www.producthunt.com/posts/onboard-ai))
