CtxVault vs. the Alternatives
An honest side-by-side, including where CtxVault doesn't win.
There are a few genuinely different ways to keep large pastes from flooding an AI CLI's context. None of them is strictly better on every axis, so here's a plain comparison instead of a sales pitch.
| Approach | Trigger & scope | What the AI actually gets | Local/cloud & cost |
|---|---|---|---|
| Save the file yourself, type the path | Fully manual · works anywhere you can type | Only what you type; the AI reads the file if the tool supports opening paths | Local, no extra tool involved · Free |
| @-file reference (Claude Code, Gemini CLI, Codex CLI) | Manual per paste, with autocomplete · only inside that CLI's own prompt | Full file content injected into the prompt (Claude Code, Gemini CLI); Codex CLI adds the file's path to the prompt instead, per its own docs | Local file read, built into the CLI you're already using · Free, included in the CLI |
| A classic clipboard manager | Automatic capture into history · system-wide by design | Whatever you paste, unchanged; these tools aren't built to shrink what lands in an AI's context | Varies by product, some are local-only, some sync history to an account · Varies, free tiers common, paid tiers usually add sync or longer history |
| CtxVault | Automatic, based on a size threshold · only intercepts paste in recognized terminal apps, everywhere else stays untouched | A file path; the AI reads the file's content on demand | 100% local, no clipboard content, no usage data, no telemetry · network calls are licensing-only: activate, deactivate, reactivate on device switch, periodic Polar check-in (up to every 5 days), plus an optional update check · €14,99 once, one active device |
Save the file yourself, type the path
The baseline option, and it works everywhere because it depends on nothing but you. It's also the most manual: you decide where to save it, you type the exact path, and if you get either wrong, the AI has nothing to read.
@-file references
Several AI CLIs support this natively. Claude Code's @path/to/file "includes the full content of the file in the conversation." Gemini CLI's @ commands "include the content of files or directories as part of your prompt." Codex CLI's mentions menu lets you "search for a file in the workspace and add its path to the prompt." It's fast and precise, but it's a feature of that specific CLI's interactive prompt, not a general clipboard behavior; see the full breakdown for the tradeoffs.
Clipboard managers
General-purpose clipboard managers exist to solve a different problem: finding and reusing something you copied a while ago. They're genuinely useful for that, and most run system-wide, well beyond the terminal. What they typically don't do is change the size of what actually gets pasted; the point of clipboard history is retrieval, not context management for an AI.
CtxVault
Built specifically for the terminal-and-AI-CLI case: content over your threshold gets written to a file automatically the moment you copy it, before you've decided where it's going. The terminal-specific part is what happens next: paste into a recognized terminal app and your terminal receives the file's path instead of the full text; paste anywhere else and nothing changes. €14,99 once, one active device, fully local.
