Write with focus. Add agency only when you want it.

PaperWriter begins as a free academic editor. If citations are missing, PaperWriter can find relevant sources for you, connect claims to inspectable evidence, and generate citations plus a References section for your manuscript after review. Work beside an agent when you want reviewable help, or start a separate autonomous project when you want the whole paper planned with you.

Thermal Stability of Mixed-Cation Perovskite Solar Cells

M. Santos · J. Lin · Last edited 2 minutes ago

Hybrid organic-inorganic perovskites have emerged as leading candidates for next-generation photovoltaics, yet their long-term operational stability remains the principal barrier to commercial deployment.

Recent studies suggest that partial substitution of formamidinium with cesium suppresses the photoinactive phase, extending device lifetimes under continuous illumination. We test this claim in mixed-halide compositions under elevated humidity.

One place to write. Three ways to work.

Editor

Free

Write directly

A serious editor for drafting, collaboration, version history, and export. No AI trial is required.

Agent Workspace

Optional

Work beside an agent

Keep the manuscript visible while an agent diagnoses problems and proposes bounded edits. You approve every change.

See Agent Workspace

Autonomous Writer

Credit based

Agree on the plan, then draft

Give Sol a separate project, review the evidence plan and outline, and approve the paper before full drafting begins.

Create account to start

Literature search and journal-copy preparation stay attached to the paper inside the workspace, where their records and decisions belong. Search results are candidates until you inspect and approve the supporting evidence.

Begin with your own words.

Create a paper for free. The more agentic paths remain optional.
