Double review
A focused VS Code extension for model-selectable chat, reviewable edits, and autocomplete.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Double is a VS Code extension for developers who want AI chat and code completion inside their editor. It suits solo developers and small teams looking for a focused set of coding-assistant tools: selectable language models, code-aware questions when they pass selected lines into chat, and suggestions as they type. The extension currently supports VS Code, with other editor extensions in development.
Its strongest distinction is the combination of chat and completion with a review step for generated changes. Double’s CodeSnap feature applies snippets to the open file as reviewable diffs, rather than describing edits as automatic. Autocomplete includes inline, mid-line, and multi-cursor suggestions, plus automatic imports for suggested dependencies. Chat replies can follow custom instructions, and chronological history supports continuing a conversation. This should suit developers who want to inspect suggested edits and keep chat tied to selected code. It is less suited to workflows that depend on the assistant understanding a broader codebase: the listed specifications say codebase context is not supported.
Double offers a free plan, but the published pricing document gives no plan or price details, so buyers should not assume what any paid tier includes. The listed deployment options are cloud and browser extension, while the documented editor support is VS Code; email is the listed support channel. Choose Double if model choice, in-editor chat, and varied autocomplete are the main requirements. Consider an alternative if codebase-wide context or support for another editor is essential.
