The manual · Heureka Bench for macOS and Windows

Everything Bench can do,
arranged by what you are
actually trying to do.

Heureka Bench is an electronic lab notebook with a research agent living inside it. Your projects are folders on your own disk. ARC reads, writes, analyses and keeps them in order.

How Bench works

What a workspace is, where your files actually live, and what things cost — the questions worth answering before anything else.

  • What a workspace is
  • What a project is
  • Local project or cloud project?
  • What uses credits
  • What things actually cost

and 7 more

 01

Your research record

Every project is a folder on your own disk. Bench organises it; it never takes it hostage.

  • A workspace of projects
  • Files, opened in the right viewer
  • Project rationale
  • Experiments and templates
  • To-Dos the agent can see

and 4 more

 02

ARC, inside the project

Not a chat window pasted over a folder. A collaborator that lives in the record, with the tools to change it.

  • A conversation per project
  • ARC at Home, across the whole workspace
  • Background work you can always see and stop
  • Plan mode
  • Hand it specific files — including ones outside the project

and 8 more

 03

Writing and documents

An editor with the agent wired into the text itself — and a hard rule that it never changes a saved file behind your back.

  • The markdown editor
  • Inline edit verbs
  • Edits that cannot clobber you
  • Add references
  • Review doc — propose and accept

and 6 more

 04

Data and analysis

Run it on your laptop, or hand it to the cloud and close the lid. Either way the result comes back into the project.

  • Run Analysis
  • Cloud jobs
  • Raw sequencing data, pre-processed
  • Code, read and run
  • Chemical structures

and 4 more

 05

Running the lab

Inventory, colonies, provenance, schedules — the operational half of research, in the same app as the science.

  • Inventory
  • Animal colonies
  • Provenance
  • Scheduled tasks
  • The Activity board

and 1 more

 06

Working with others

Local-first does not mean alone. Sync what you choose, share what you mean to, talk without leaving the notebook.

  • Cloud projects and two-way sync
  • Pings — talk to your lab inside Bench
  • Shared inventories, colonies and data spaces
  • When access changes
  • Your team

and 2 more

 07

Trust and control

Your data stays on your machine unless you send it somewhere. When it does move, Bench shows you the receipt.

  • Local-first, in the literal sense
  • The agent never silently changes a saved file
  • Privacy Mode
  • The receipt, not just the promise
  • Sharing starts off

How to read this

As a manual

Every entry says where the feature lives in the app, so you can go and use it. Search with /, or open every feature A–Z if you already know what you are looking for.

If you are new

Start at 00 — How Bench works. It answers what a workspace is, the difference between a local and a cloud project, and exactly what does and does not use credits. The sections after it follow the way research actually runs.

On accuracy

Bench ships often, so this is kept current rather than pinned to a version. Every page carries the date it was last checked against the app.
