## Lettria

Lettria addresses the well-known limit of vector search: the moment a question needs several sources or a chain of relationships, plain similarity retrieval starts to fray. Lettria's answer is to build an ontology-powered knowledge graph over the organisation's own material — documents, tables, ERP exports, technical manuals — and then let AI systems retrieve through explicit relationships rather than fuzzy matching. The pitch is that vectors retrieve while graphs reason.

The product stack splits into two surfaces. Knowledge Studio is the graph-native document intelligence platform aimed at knowledge and business teams in regulated sectors such as finance, healthcare, legal and engineering, where traceability and audit-readiness matter. Perseus is the developer-facing layer for generating ontologies and knowledge graphs quickly and putting graph-based agents into production, keeping domain experts in the loop for review and version control.

Because answers carry their provenance — the documents and the reasoning path behind them — Lettria suits workflows that must survive regulatory scrutiny rather than casual Q&A. Deployment involves a sales conversation rather than self-serve signup, and the company also offers forward-deployed engineering and ontology expertise for complex rollouts.

**Pricing & Plans:** Contact for pricing — enterprise plans and demos are arranged through the sales team, with no public self-serve tier.

- **Ontology generation:** Auto-generate production-grade, version-controlled ontologies from domain data instead of hand-modelling them over months.
- **Text-to-Graph pipeline:** Convert messy documents, tables and exports into a clean, queryable knowledge graph that unifies structured and unstructured sources.
- **GraphRAG retrieval:** Multi-hop reasoning across connected knowledge with full provenance on every answer, designed for auditability.
- **Knowledge Studio:** A graph-native document intelligence workspace for regulated industries, focused on accuracy, compliance and traceability.
- **Perseus developer platform:** Infrastructure for building, versioning and shipping production-grade graph agents with experts reviewing the results.

**Strengths:** Answers carry provenance, which matters for regulated industries; Handles structured and unstructured data in the same graph; Ontology generation cuts months of manual knowledge modelling; Published benchmarks compare graph agents against vector retrieval

**Limitations:** Enterprise-only engagement; no self-serve trial or transparent public pricing; Value depends heavily on having substantial, well-defined domain knowledge to structure; Requires domain experts in the loop, so it is a project not a plug-in

## Notion

Notion started as a flexible document and note-taking tool and has grown into a full AI-native workspace used by individuals, startups, and large enterprises. It lets you build a single system of record where pages, databases, tasks, and wikis live together, then layer Notion AI on top so you can draft, summarize, translate, and query that content without leaving the app.

The platform's newer direction centers on agents and enterprise search. Custom agents can be built to handle recurring workflows — triaging product feedback, resolving support tickets, or automating weekly reporting — while unified search pulls answers from Notion and connected apps with citations. Because everything is stored in the same structured workspace, AI has real context to work from.

Notion is available on web, desktop, and mobile, and there is a generous free tier plus paid plans for individuals, teams, and enterprises. It is widely adopted, with the company reporting over 100 million users across more than 50 countries, and it is frequently used as a company-wide knowledge base and project hub.

**Pricing & Plans:** Freemium model: a free plan covers personal use and small teams, with paid Personal, Team, Business, and Enterprise tiers plus AI add-ons. Larger organizations typically contact sales for custom pricing.

- **Connected workspace:** Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
- **Notion AI assistants and agents:** Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
- **Unified enterprise search:** Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
- **Flexible databases and templates:** Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
- **Cross-platform apps and integrations:** Work on web, desktop, and mobile, and connect the tools your team already uses through integrations and the public API.

**Strengths:** Very flexible — docs, databases, and project management in one tool; Strong AI features for search, writing, and workflow automation; Generous free plan and broad template ecosystem; Available on web, desktop, and mobile with a mature API

**Limitations:** Flexibility means setup time can be significant for teams; Advanced AI and enterprise features sit on higher-priced tiers; Large workspaces can feel slow or cluttered without good structure
