Show HN: Atombot – atomic-lightweight AI assistant for local models and GPT‑5.4

[gwangee]

Atombot(repo: https://github.com/daegwang/atombot) is a tiny self-hosted personal AI assistant I built because I wanted something I could understand and extend end-to-end.

Core functionality is ~500 lines (vs ~400k in OpenClaw). It includes:

- Persistent memory with searchable daily history logs

- Telegram gateway (allowlist-based access)

- One-time + recurring reminders

- Provider-first onboarding that auto-detects Ollama / LM Studio / Codex

Atombot also supports GPT‑5.4 via Codex CLI, so you can select easily during onboarding.

Feedback welcome. Stars appreciated!
