Configuration

Everything here is explained in plain words, and the live preview shows each change as you make it. Keys stay on the computer running CustomChat. Use an environment variable, or paste one on the Model tab to save it in a private local file. It is never shown again.

Presets and saved statesStart from a ready-made look, or save and reload your own setups

A preset changes colors, fonts, background and shape in one click. You can still adjust anything afterwards. Changes save by themselves.

Portable appMove this app to another computer

Export app.yaml, the current model settings, saved look, prompts and configured local documents. Keys, accounts, conversations and personal uploads stay here. Review included documents before sharing. Python plugins and remote services still need their original setup.

Document freshnessKeep local evidence up to date

Local folders are checked when someone asks a question, at most once every 30 seconds by default. Changed, added and removed documents update the search index. No background polling or model calls. Set refresh_interval in the local source YAML to change the interval.

BudgetLimit public chat usage

Daily limits reset at midnight UTC and survive restarts. 0 means no quota. Model-call limits cover answer-pipeline calls, including follow-ups and provider fallback as one invocation. Failed attempts count. Configuration tests/generation and provider-side retries are not counted individually.

Questions per day, whole app Questions per user per day Model calls per day Dollar cap (USD)

Dollar accounting is not available yet. Setting any dollar cap blocks non-Demo answer-pipeline calls rather than guessing a bill. It does not limit owner-run configuration tests, external search fees or embedding costs. Set provider-side billing limits before publishing.
