No cloud. No exceptions.
CoSci runs on your machine. Your unpublished data, hypotheses and grant ideas never leave it — online mode sends only what you approve, only to the provider whose key you supplied.
CoSci is an open-source research co-scientist that runs the full research cycle locally — idea to manuscript — grounded in real scientific tools, gated by the scientific method, and always under your approval.
Runs offline & online · your data never leaves · open source under AGPL-3.0
The wedge
Cloud AI-for-science trades away privacy, rigor and control. CoSci is built on exactly those three.
CoSci runs on your machine. Your unpublished data, hypotheses and grant ideas never leave it — online mode sends only what you approve, only to the provider whose key you supplied.
Every literature sweep and citation check hits real databases through ToolUniverse. Claims are audited against references that actually exist — grounded, not generated.
Sensitive actions are enqueued, not executed. Three task classes — needs input, needs approval, AI-can-execute — keep you in command of every step.
An experiment can't be marked Ready until it has hard kill-criteria and named artifact risks. The discipline of the scientific method, encoded as a gate.
Idea → question → mechanism → experiment → belief update → manuscript, all versioned and auditable. Your research memory compounds instead of scattering across chats.
A built-in heuristic engine runs with zero keys. Add an LLM and real tools when you want them; CoSci uses the best provider available and falls back gracefully.
The lifecycle
Not a point tool — CoSci walks every stage with you, and versions all of it.
Throw in a rough idea; get ranked candidate questions.
Narrow to one specific, doable question worth answering.
Lay out competing explanations, not a single guess.
Design the test — gated by hard kill-criteria.
Record real observations against your predictions.
Revise confidence as evidence comes in.
3-agent proposal & manuscript packets, with a critic.
Everything lands in a versioned wiki + canvas memory.
The hinge of the whole thing: an experiment can't be Ready without hard kill-criteria and named artifact risks.
Grounded in real science
Literature sweeps, citation checks and protein/structure context reach real sources through the ToolUniverse layer. Real and cited.
A complete worked example
One reproducible run in the repo does the whole loop with real tools:
$ uv run python walkthrough_conflict.py incubate idea ................. ok literature sweep .............. ok real resolve proteins (UniProt) .... ok RpoB DnaB Mfd Rep domains + PDB (InterPro/PDB) .. ok killer experiment ............. ok kill-gate passed proposal + citation gate ...... ok 2024–26 refs → test-results/conflict-walkthrough/REPORT.md
How it works
One machine, your keys (or none), the whole workflow.
Double-click start.command (or run it). First run builds the UI, seeds a profile, and opens the cockpit at localhost:8799.
./start.command
Point it at the Claude or Codex CLI, Gemini, or DeepSeek. No key? The heuristic engine runs fully offline.
RC_OFFLINE=0 # or 1 for hard offline
Capture an idea, incubate it, sweep the literature, build mechanism context, design the killer experiment — with you in the loop.
open http://localhost:8799
No price, no trial, no bot in your lab. CoSci will be released under AGPL-3.0 — local-first, bring-your-own-key, or fully offline. The private beta is open now.

Yes. CoSci is local-first: it runs on your machine and stores everything in a local SQLite database. Nothing is uploaded anywhere by default. In online mode, only the content you approve is sent — and only to the AI provider whose API key you configured.
It's designed not to. Literature sweeps and citation checks go through ToolUniverse to real databases (PubMed, Europe PMC, Semantic Scholar, UniProt, InterPro, PDB). A citation-existence gate audits each claim against references that actually exist, so 'it won't invent a paper' is a concrete promise, not a hope.
No — a built-in heuristic engine runs the whole workflow offline with no keys at all. Add a provider (the local Claude/Codex CLI, Gemini, or DeepSeek) when you want stronger reasoning and real tool calls. CoSci picks the first available provider and falls back automatically.
It walks the full research cycle: incubate an idea into ranked questions, sharpen one, lay out competing mechanisms, design a killer experiment behind a kill-criteria gate, record observations, update beliefs, and draft proposal/manuscript packets — all versioned in a wiki + canvas memory. A reproducible worked example (a DNA replication–transcription conflict) ships in the repo.
Working scientists — grad students, postdocs and PIs — who want an AI collaborator they can trust with unpublished work. It's especially aimed at life sciences, but the workflow is domain-general.
Yes — CoSci is released under AGPL-3.0. You can read it, build it, and self-host it. It's an actively developed project provided as-is.
Not yet. The local-first app is the product today. Managed cloud sync and a shared lab/team workspace are on the roadmap — the same 'your data stays yours' story, for people who'd rather not self-host.
