## DECipher

Global development organisations sit on decades of documented field experience, but that knowledge is scattered across thousands of reports that almost nobody has time to read. DECipher, developed by the Institute for Development Impact (I4DI), turns that archive into something you can question. It draws on more than 13,000 documents from the Development Experience Clearinghouse, covering roughly 75 years of USAID-funded work, and returns recommendations matched to the prompt a practitioner actually wrote.

What separates it from a general-purpose chatbot is CREW AI, a set of cooperating LLM agents. Rather than one model answering everything, specialised agents cover methodology, technical design, project implementation, monitoring evaluation and learning, rules and regulations, and communication. The system is transparent about which models it uses, listing Mistral Mamba-Codestral-7B and the Llama 3.1 family, and each agent contributes its own slice of domain knowledge to the final answer.

The intended audience is NGOs, government agencies, implementing partners and independent consultants who need defensible answers rather than plausible-sounding ones. I4DI positions DECipher as a public good offered free of charge, with the goal of giving small grassroots organisations access to the same research capacity as large institutions. Because the underlying corpus is a specific institutional archive, it is strongest on USAID rules, program design conventions and evaluation practice, and it should be treated as a research accelerator rather than a substitute for formal compliance review.

**Pricing & Plans:** DECipher is offered free of charge as a public good, per I4DI's own description. No paid tiers are published on the site.

- **13,000+ document knowledge base:** Draws on USAID's Development Experience Clearinghouse, spanning about 75 years of funded development projects, studies and evaluations.
- **CREW AI multi-agent system:** Specialised LLM agents each handle a domain, so methodology, compliance and communications questions get purpose-built reasoning rather than one generic answer.
- **Domain agents for real workflows:** Dedicated agents cover methodology and sample sizing, technical design, project implementation, MEL and KPIs, USAID rules, and communication support.
- **Transparent model stack:** The platform openly names the models behind its agents, including Mistral Mamba-Codestral-7B and the Llama 3.1 family, so users know what is generating answers.
- **Built for scale:** Designed to absorb growing datasets and user numbers as new development learning becomes available.

**Strengths:** Free to use, positioned explicitly as a public good; Grounded in a real institutional archive rather than open-web scraping; Multi-agent design produces specialist answers instead of one generalist response; Model stack is disclosed rather than hidden

**Limitations:** Knowledge is centred on USAID documentation, so non-USAID contexts are covered unevenly; No published paid tier or SLA, so enterprise support expectations should stay modest; AI output still needs verification against current official guidance

## Semantic Scholar

Semantic Scholar was launched by the Allen Institute for AI as an attempt to solve a very specific problem: scientific output grows far faster than any individual researcher's ability to read it. Instead of matching literal keywords, the platform applies natural-language processing and graph analysis to figure out what a paper is actually about, who it builds on, and which citations inside it mattered — surfacing papers a keyword search would never rank highly.

The catalog spans more than 240 million publications from journals, conference proceedings, preprint servers and repositories, with records combining metadata, abstracts, references, citation counts and extracted entities such as methods, datasets and figures. On top of the core search experience sit features like one-sentence AI TLDRs, Semantic Reader (an augmented PDF reader that surfaces inline citations, definitions and figures while you read), author and venue pages, research feeds, and a Scholar's Hub for tracking the people and topics you care about.

Everything on the site is free to use, and a developer API gives researchers, students and engineers programmatic access to the same corpus — the API now supports paper search, better documentation and improved stability. Because it is a non-profit academic project rather than a commercial product, there is no paid tier: the value proposition is depth of coverage and semantic relevance, not premium features.

**Pricing & Plans:** Completely free. Semantic Scholar is operated as a non-profit academic project by the Allen Institute for AI, with no subscription tiers — accounts, search, Semantic Reader and the developer API are all available at no cost.

- **Semantic search across 240M+ papers:** Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
- **AI-generated TLDR summaries:** Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
- **Semantic Reader:** An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
- **Citation context and influence signals:** See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.
- **Free developer API and Scholar's Hub:** A documented public API exposes search and metadata endpoints at no charge, while Scholar's Hub lets you follow authors, topics and citation alerts.

**Strengths:** Free to use with no paywall, subscription or credit limits; Very broad coverage spanning 240M+ papers in all scientific fields; Semantic ranking and AI TLDRs surface relevant work that keyword search misses; Semantic Reader adds inline citations, definitions and figures during reading

**Limitations:** Indexing lag means the newest preprints are not always immediately available; TLDR summaries are machine-generated and can oversimplify nuanced findings; Full text is frequently limited to what publishers or repositories expose; Not a citation manager: no built-in PDF library, BibTeX export workflow or note system
