I spend hours everyday researching AI products. Why am I only hearing about plandex now? Looks very promising, I’ll give it a try. Please up your marketing game, the product looks solid!

> It seems that much like Aider, you use separate models for creating code edits and validating them. That's right. To apply edits, Plandex first attempts a deterministic edit based on the edit snippet. In some cases this can be used without validation, and in others a validation step is needed. A "race" is then orchestrated with o3-mini between an aider-style diff edit, a whole file build, and (on the cloud service)…
What are the main differences from aider?
- Plandex is more agentic—it can complete a complex task, updating many files, all in one go.
- Changes are applied to a sandbox by default rather than directly to project files, helping you prevent unintended changes.
- Plandex can automatically find the context it needs in the project.
- Plandex can execute commands (like installing dependencies, running tests, etc.) and auto-debug if they fail.
- Plandex should be more reliable on file edits—it uses an enhanced version of aider's diff-style edit that is resilient to multiple occurrences, but it also has validation, a whole file fallback, and on the cloud service, a custom fast apply model is also added to the mix. Will be publishing benchmarks on this soon.

Thanks, I appreciate the feedback. > Oddly, in the default mode out of box it does not want to discuss the plan with me but just jumps to implementation. It should be starting you out in "chat mode". Do you mean that you're prompted to begin implementation at the end of the chat response? You can just choose the 'no' option if that's the case and keep chatting. Once you're in 'tell mode', you can always switch back t…
Here's what happened: 1. It started formulating the plan 2. Got error from provider (it seems model set sometime randomly resets to default?!?) 3. After I switched to different provider, I want it to continue planning, so I use \continue command 4. But when it gets \continue command it starts writing code without asking anything! 5. In the end it was still in chat mode. I never switched to tell mode, I just wanted it…
The model pack shouldn't be resetting, but a potential gotcha is that model settings are version controlled, so if you rewind to a point in the plan before the model settings were changed, you can undo those changes. Any chance that's what happened? It's a bit of a tradeoff since having those settings version controlled can also be useful in various ways.
This feedback is very valuable, so thanks again!

Are you getting paid to research AI products in some capacity or is this a personal interest and time investment?
