## Software

- [Copilot Pacer](https://nirlotan.com/CopilotPacer/): Free, open-source macOS menu-bar and Windows system-tray app that answers "will my GitHub Copilot credits last the month?". It compares the Copilot credits you have used with a healthy pace that counts only your working days (weekends, public holidays for 200+ countries and personal days off excluded), and shows a ring that turns green (on pace), amber (within tolerance, 5 points by default) or red (over pace, with one notification a day). Shows a daily budget and an end-of-cycle forecast. Works with Copilot Individual, Business and Enterprise. Talks only to GitHub; no analytics or telemetry. Supports corporate proxies (PAC/WPAD). Built with Tauri and Rust. Source: https://github.com/nirlotan/copilot-pacer
- [GlideDeck](https://nirlotan.com/GlideDeck/): Zooming presentation app for Windows and macOS. Lay a talk out on one canvas and fly the camera between frames. Native, written in Rust, imports and exports PowerPoint, works offline. Source: https://github.com/nirlotan/GlideDeck
- [SocialVec](https://github.com/nirlotan/SocialVec): Python library of social entity embeddings, learned from which accounts people follow together. Install with `pip install socialvec`.
- [Likewise](https://likewisechat.com/): Web app for chatting with an AI persona who shares your taste in music, shows and teams, and one who does not.

## Copilot Pacer details

- How the healthy line works: healthy % = working days elapsed (including part of today) ÷ working days in the billing cycle × 100. Daily budget = (100 − used %) ÷ working days left.
