Instruction precedence
Safety and the current request always outrank stale context, memory and model defaults.
More than a model in a chat window.
Rangabot coordinates private models, approved knowledge, selective memory and bounded local tools—then exposes enough of the process to earn trust.
Mind
The model speaks. Rangabot decides what it should know.
A model-independent control plane compiles the current request, recent context, relevant approved memory and capability boundaries into one inspectable answer contract.
Bounded context
Only useful recent conversation is carried forward, avoiding unlimited prompt growth.
Truthful capability
Unavailable actions and live information are stated honestly instead of being simulated.
Memory
Remember deliberately. Forget completely.
Memories are explicit local records with origin, confidence and controls. A normal conversation does not silently become a permanent fact.
Approval first
The user decides what becomes reusable memory.
Topic-aware selection
Unrelated personal facts stay out of the prompt and response.
Inspectable control
Review, edit, export, supersede or delete local memory.
Scholar
A private library that knows where an answer came from.
The Knowledge Vault extracts supported documents locally, combines keyword and embedding search, and gives the model bounded source passages for teaching and synthesis.
Hybrid retrieval
Keyword precision and semantic similarity work together with a visible fallback.
Source locators
Answers cite the document, passage and available page or section context.
Evidence separation
Vault-supported claims remain distinct from downloaded-model background.
Analyst · experimental
Ask in ordinary language. Inspect the calculation.
With explicit read-only access, Rangabot identifies when computation is required, compiles a constrained analytical plan and explains the verified local result.
Permission boundary
A file must be allowlisted and attached to the current conversation.
Bounded execution
Only validated read-only SQL runs inside local DuckDB resource limits.
Visible receipt
Dataset, query, row count, timing and fingerprints stay available for review.
Builder
Bring the right piece of a repository into the conversation.
Rangabot searches only approved folders, skips common secret and dependency paths, and attaches bounded file previews to local-model chat.
Scoped repository access
Approvals are explicit, reversible and stored only on the local device.
On-demand context
There is no hidden background repository index.
Creation with checks
Word creation gathers requirements in chat, validates output and can render local previews.
Available, experimental and planned abilities are labelled separately. Visit Evidence for exact results or Path to Mastery for criterion-level progress.
