Supplementary information, rethought

Frustrated spending weeks making your Supplementary
Information?

SynthWriter turns your lab notebook and characterization data into a validated, journal-formatted SI document — in the time it takes to review it, not retype it.

What SynthWriter does to a paragraph like this

Your notebook + raw data

1a: white solid, mp 142-144. 1H NMR (CDCl3) 7.3 (m, 4H), 3.9 (s, 3H)… HRMS calc 254.1 found 254.0989. still need IR + 13C for JACS

Warning Missing IR Missing 13C Needs review

SynthWriter

Publication-ready SI text

1a. White solid (142–144 °C). ¹H NMR (400 MHz, CDCl₃) δ 7.34–7.28 (m, 4H), 3.91 (s, 3H)… ¹³C NMR (101 MHz, CDCl₃) δ 165.2, 159.8… IR (neat) ν_max 1708, 1608 cm⁻¹. HRMS (ESI) m/z calcd for C₁₅H₁₄NO₂ [M+H]⁺ 254.1176, found 254.1179.

JACS format Complete Validated

That paragraph used to take you three days.

Reformatting the same ¹H/¹³C/IR/HRMS block by hand for every journal's house style.
Cross-checking which fields are required for a novel vs. known compound — and catching it only at proofs.
Retyping lab notebook shorthand into formal, third-person SI prose, compound by compound.
Losing an evening to Word or LaTeX formatting instead of writing the paper.

The fix

Everything between your bench and your SI

Digital Labbook

Photograph a notebook page. SynthWriter reads the stoichiometry, reagents, and procedure straight into a structured experiment record — cross-checked against the limiting reagent automatically.

Journal-aware formatting & validation

Pick a target journal — JACS, Angewandte, RSC — and every NMR, IR, and HRMS line is formatted to its house style. Missing or inconsistent data is flagged before you submit, not after review comes back.

Chemistry-aware engine

Built on a real cheminformatics core, not text templating: e.g. correctly splits diastereotopic and ring-shaped carbon environments that generic tools get wrong, and resolves a chemical name straight to structure, formula, and molecular weight.

One-click export

Markdown, LaTeX, or DOCX — ready to paste straight into your manuscript or submission portal.

Local-first & portable

Your data lives in your browser, not our servers. Export a full project bundle any time and take it with you.

The workflow

From bench to submission in three steps

1
Capture

Photograph your notebook page, or type it in — either becomes a structured experiment record.
2
Validate

SynthWriter checks every compound against your target journal's requirements and flags what's missing or inconsistent.
3
Export

Download a publication-ready SI document in Markdown, LaTeX, or DOCX.

Stop retyping. Start submitting.
