The lab notebook for synthetic and cell biology
Plan, run and analyze experiments in one notebook.
Turn an existing protocol or methods section into a draft you can review. Run it at the bench, record what changed, and keep the results beside the question that started it.
Running a lab? See what Gelly does for PIs or book a 30-minute walkthrough.

How Gelly is organised
Three parts of an experiment, one record.
Plan research
- Talk an experiment through with a voice colleague that read your papers
- Literature from Europe PMC and PubMed, with your highlights
- Hypotheses with reasons, and the test that would settle them
Execute experiments
- A protocol from a methods section or a sentence
- Bench mode on the phone, hands-free, with timers
- Inventory, equipment booking and deviations in the run log
Analyze data
- Gel photos: band sizes and amounts
- FCS files and FlowJo gates, compared by group
- Microscopy counting and tracking over time
Example notebooks
See what a finished notebook looks like.
Exported Gelly notebooks that follow one question from the papers to the result. Open one, read it like a paper, then copy it into your own Gelly.
Inventory
Know what's in the freezer before you open it.
Reagents, samples, plasmid stocks and consumables with their freezer, box and slot. Scan a bottle to add it; before a run, the protocol tells you what to gather and what to order.
Mac and Windows
The phone runs the bench. The desktop does the heavy work.
Search everything with ⌘K, drop FCS folders and microscopy stacks, read papers beside your notebook, and let Claude Code or Codex work in your notebooks.

For lab heads
Know what your lab did, and why.
When a student leaves, their protocols, runs and deviations stay with the lab. You see every running experiment, who changed what, and which results an AI helped with.
Pricing
A predictable seat. Pay for results you keep.
Free for one person. Labs pay a small seat per person, and AI results only when they keep them: a protocol you accept, an answer you save, a minute you talk.

- Encrypted shared pagesShare a protocol as a web page. The key stays in the link, the server can't read it.
- Choose your AI modelPick per question: GPT for the strongest reasoning, or DeepSeek V4.1 Flash hosted in Paris to keep data in the EU.
- Plasmids, antibodies, organismsReal map files, RRIDs and Cellosaurus lines as notebook cards.
- Lecture captureRecord a talk, transcribe it and enhance your notes from it. In the next release.
- Signed, timestamped recordsEvery block says who added it, and which model wrote AI content.
