## Constellab

Constellab is a sovereign European data and AI platform for life sciences and digital health, developed by Gencovery and designed 'by scientists, for scientists'. It acts as an all-in-one innovation hub that consolidates, transforms and valorises scientific data, connecting teams, datasets and instruments so research can move from raw data to insight without stitching together disconnected tools.

The platform is built around the idea of a digital lab: a modular environment assembled from reusable bricks, each adding a capability such as omics analysis, microbial genomics or biomath conversion. Teams combine these bricks into tailored workflows, then run, share and reuse them. Related apps, including community-built tools, extend the ecosystem further.

Sovereignty is central to the proposition. Constellab can run in the cloud, on-premises or at the edge, keeping sensitive data under the organisation's control, and every step of a workflow is traceable to support reproducibility. A companion community platform shares knowledge and best practices, while the open-source foundations are published on GitHub. Pricing is arranged with Gencovery based on user type and deployment.

**Pricing & Plans:** Constellab is priced on request. Gencovery offers flexible options that differ for individuals, organisations and academic users, and by deployment model (cloud, on-premises or edge). Contact the team for a tailored quote.

- **Customisable Digital Labs:** Assemble analysis pipelines from reusable method bricks so scientific workflows are reproducible and easy to share across teams.
- **Data Consolidation & Harmonisation:** Bring together data from instruments, files and external sources into one governed, traceable environment.
- **Sovereign & Secure Deployment:** Choose cloud, on-premises or edge deployment so sensitive life-sciences data stays where governance requires.
- **Project, Search & Analytics Suite:** Manage research projects, search across datasets and run analyses from a unified workspace built for scientific teams.
- **Traceability & Governance:** Track how data moves through every step of a workflow to support reproducibility and regulatory expectations.

**Strengths:** Purpose-built for life-sciences and health data rather than general-purpose analytics; Modular brick architecture makes digital labs configurable to very specific domains; Sovereign deployment options keep sensitive research data under organisational control; Strong traceability supports reproducibility and governance requirements

**Limitations:** Pricing is not published publicly and requires contacting sales; The platform is broad, so small teams may only use a fraction of its capabilities; Best suited to life-sciences and health organisations rather than general business use; Self-hosting on-premises or at the edge adds infrastructure overhead

## LightPDF

LightPDF positions itself as an all-in-one document workspace rather than a single-purpose converter. The classic side of the product covers the essentials most people need every day: viewing and editing PDF text and images, converting between PDF and Office/image formats, OCR for scanned files, merging, splitting, compressing, watermarking, signing and annotating. Because everything runs in the browser with companion apps for Windows, Mac, iOS and Android, the same account and files travel with you across devices.

The AI layer is where the product has expanded most. An AI agent lets you chat with an uploaded document, ask follow-up questions and trace answers back to citations, while a separate chat experience works on YouTube videos. Document translation preserves the original layout across 20+ languages, including scanned and image-based PDFs, and structured data extraction turns invoices, receipts, bank statements and purchase orders into editable spreadsheets. Rounding out the suite are an AI PPT generator, mind-map and summary generation, watermark and sticker removal, text and logo erasing, document enhancement for scanned pages and an AI invoice generator.

Pricing follows a freemium model with a free tier (10MB file limit, watermark on some exports) and paid plans that add unlimited file sizes, batch processing, cloud storage and monthly AI credits. Individual subscriptions start around $5.99 per month, with a yearly option near $15.99 and a one-time lifetime plan; credits are consumed per AI action, so heavy AI users can top them up. Team, business and education plans are available on request.

**Pricing & Plans:** Freemium. A free plan covers basic PDF tools with a 10MB file cap; paid plans start around $5.99/month, with a yearly tier and a one-time lifetime option. AI features consume monthly credits that differ by plan.

- **AI document agent and chat:** Upload a PDF and ask questions in natural language, follow up on details and see which passages the answers came from. A separate chat mode works with YouTube videos.
- **Layout-preserving translation:** Translate whole documents, including scanned and image-based PDFs, into 20+ languages while keeping the original formatting and layout intact.
- **AI data extraction to spreadsheets:** Convert invoices, receipts, bank statements and purchase orders into structured, editable Excel files automatically.
- **Full PDF editing and conversion suite:** Edit text and images, OCR scanned pages, convert to and from Office formats, then merge, split, compress, watermark, sign and annotate.
- **Cross-platform access:** One account works on web, Windows, Mac, iOS and Android, so documents and paid features follow you between devices.

**Strengths:** Very broad toolkit that covers both everyday PDF chores and advanced AI document tasks; Free tier is usable for light jobs, and the paid plans are cheaper than many competing PDF editors; Layout-preserving translation and AI data extraction handle scanned documents that trip up simpler tools; One subscription covers five platforms, including desktop and mobile apps

**Limitations:** Free plan caps files at 10MB and adds watermarks on some outputs; AI features run on a credit system, so heavy usage means top-ups or a higher tier; Advanced AI operations like text editing or logo removal consume credits quickly
