You press a hotkey, an overlay appears, and you can paste or send prompts instantly. No subscription, no account, no data leaving your machine.</p> <p>It started because Logitech killed Logi Prompt Builder. Hardware locked, closed source, gone. That felt wrong. So I built what that should have been.</p> <p>What it does:<br> **<br> Press a hotkey, overlay appears, type or paste your prompt, send.** Works with OpenAI, Anthropic, Google, xAI, or any OpenAI-compatible API. Or run it fully local with the built-in llama.cpp engine (auto-downloads, auto-unloads, no setup).</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2F3c7lxxvluscjb7grtf9q.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2F3c7lxxvluscjb7grtf9q.png" alt=" " width="773" height="1021"></a></p> <p>U might like it bc:</p> <p><strong>- Time saver, and flow maker.</strong></p> <ul> <li>22 built-in prompts plus a tab system and prompt builder</li> <li>4 languages (EN, FR, ES, CN)</li> <li>MIT licensed.

I build my own tools and share them when they feel useful. T+ is one of those tools.</p> <p>If you try it, let me know what you think.
