paperdebugger
PaperDebugger is a Chrome extension that integrates AI-powered writing assistance directly into Overleaf, helping researchers improve academic papers through intelligent suggestions, critique, and revision workflows. It uses a custom multi-agent orchestration engine (XtraMCP) to simulate research, critique, and revision cycles without modifying the original document.

What paperdebugger is
TypeScript-based browser extension with Go 1.24+ backend (Gin/gRPC microservices), MongoDB persistence, and OpenAI API integration. Features JWT/OAuth authentication, custom MCP orchestration engine, and Protocol Buffer APIs for structured multi-step reasoning workflows in academic writing contexts.

Best use cases
Implementation considerations
- Backend self-hosting requires Go 1.24+, MongoDB, and OpenAI API credentials; development setup documented in DEVELOPMENT.md but production hardening steps not detailed in excerpt.
- Chrome extension dependency limits reach to Chrome-based browsers; Firefox, Safari, or mobile workflows require separate tooling.
- XtraMCP orchestration engine (referenced in docs/xtramcp/readme.md) is custom and not yet widely tested in production; verify performance and failure modes in your domain before large-scale adoption.
- JWT/OAuth authentication assumes Overleaf or self-hosted identity provider integration; non-standard auth schemes may require custom backend modification.
- Data isolation: extension reads LaTeX content; verify logging, caching, and API call handling meet your institutional data governance policies.
When to avoid it — and what to weigh
- Need non-LaTeX document support — PaperDebugger is purpose-built for Overleaf/LaTeX. Google Docs, Word, or plaintext workflows are not supported; consider alternatives like Grammarly or native LLM plugins.
- Require strong production SLA or enterprise support — README indicates the team is actively working to improve 'long-term reliability' and notes they are 'hoping to iron out issues this month.' Production-critical workflows should verify stability and support terms first.
- Cannot accept AGPL-3.0 licensing obligations — The project is licensed under AGPL-3.0, which requires derivative works and network-distributed versions to be open-source. Proprietary or closed-source modifications trigger copyleft obligations; requires legal review for commercial integration.
- Heavy reliance on offline or air-gapped environments — The system requires OpenAI API calls and backend connectivity. Fully offline operation or restrictive network policies will block core functionality.
License & commercial use
AGPL-3.0 (GNU Affero General Public License v3.0). This is a copyleft license requiring that any derivative work, modification, or network-distributed version must also be open-source under AGPL-3.0 and provide source code to users upon request. Purely internal use (self-hosted) on private networks is permitted; public-facing services or redistributed binaries trigger disclosure obligations.
Commercial use of the unmodified software as-is (via the Chrome Web Store) appears permissible as a user. However, any proprietary modifications, custom backend integrations, or resale of derived versions triggers AGPL-3.0 copyleft obligations—source code must be made available to users and licensees under the same terms. Requires legal review before integrating into commercial products or services. No proprietary commercial license noted in the repository.

Extension reads LaTeX content from Overleaf and sends it to backend for AI processing; data residency and retention policies not disclosed. JWT/OAuth authentication is in place, but no mention of encryption in transit, input validation rules, or audit logging. Self-hosted deployments inherit their operator's security posture. No public security policy, responsible disclosure process, or third-party audit record referenced. Treat as emerging tooling; conduct security assessment before handling sensitive research or confidential manuscripts.
Alternatives to consider
Overleaf native AI features or ChatGPT plugins
Overleaf may add built-in AI writing tools; ChatGPT's web plugin ecosystem avoids extension installation and AGPL licensing but lacks LaTeX-specific orchestration.
Grammarly or ProWritingAid
Established writing assistants with broader document format support, stronger SLAs, and simpler licensing, though less suited to academic multi-step reasoning workflows.
Custom internal LLM integration (Claude API, Llama fine-tuning)
Full control over model, data, and licensing, but requires engineering effort to build Overleaf-specific UI and MCP-style orchestration; no turnkey product.
