what AI can build

Install an open-source IDE assistant, connect model APIs or a local model, index the repo, and generate code/edit suggestions.

You can use open-source editor agents and local/API models, but Copilot's value is editor integration, model routing, GitHub context, completions, and managed usage.

the prompt

Catalog estimate
Build me a local-first coding assistant setup to replace GitHub Copilot. Requirements:

- Do not build or train a model. Set up the open-source Continue extension in
  VS Code, configured against models I control.
- Chat and edit model: Claude or GPT over API, key referenced from my
  environment, never committed. Autocomplete model: a small local coder model
  served by Ollama, so completions are free and work offline.
- Deliver the actual Continue config file with both models wired, plus
  sensible keybindings for inline edit and chat.
- Enable Continue's codebase indexing for repo-aware answers; document where
  the index lives and how to rebuild it.
- Add scripts/ai-review.sh: pipes `git diff` to the API model (key from .env)
  and prints a short pre-commit review.
- Everything local except the chat-model API calls; turn off the extension's
  telemetry in the config.
- Out of scope: writing an editor extension from scratch, GitHub PR-bot
  features, team seat management.
- README: Ollama install and model pull commands, where keys go, and an honest
  note that local autocomplete is slower and dumber than Copilot's, that is
  the trade for free and private.

questions

Can AI replace GitHub Copilot?

Possibly for a narrower core workflow, but this catalog judgment is not a verified build. Expected gaps include: native GitHub/IDE integration, fast completions. Validate the prompt against your own acceptance criteria before committing.

How much does GitHub Copilot cost?

GitHub Copilot is listed at about $10/month (Pro, checked 2026-07-30), or $120 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.

What do I lose by replacing GitHub Copilot?

Honestly: native GitHub/IDE integration; fast completions; model routing; code review/security features; managed billing; team controls. If any of those are load-bearing for you, keep paying.

Is there an open-source alternative to GitHub Copilot?

Yes — Continue (Open-source coding assistant extension that connects to local or hosted models.). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
