Pimjo

Freemium

All-in-one AI workspace giving teams unified access to 51+ frontier models like GPT-5, Claude, and Gemini with shared credits and collaboration.

Key features

  • Multi-Model Access: One account gives instant access to 51+ frontier LLMs including GPT-5, Claude, Gemini, DeepSeek, Grok, Mistral, and LLaMA.
  • Compare Mode: Run the same prompt across several models side by side to pick the best output for each task.
  • Document-Aware Chat: Upload PDFs, spreadsheets, docs, and code for grounded answers without copy-pasting content into the prompt.
  • Team Workspaces: Shared chats, roles, project context, and reusable prompts included on every plan for real-time collaboration.
  • Shared Credit Pool: Teams pay for shared usage credits instead of per-seat fees, so light users do not drive up cost.
  • Chrome Extension: Access Aymo alongside any web app for quick assistance without switching tabs.
  • Free Utility Tools: Bundled PDF summarizer, email writer, and marketing helpers usable outside the paid workspace.

Best for

  • Model Comparison: Marketers or engineers can A/B-test the same prompt across GPT, Claude, and Gemini before committing.
  • Team Knowledge Base: Shared project prompts and chats keep a distributed team aligned on tone, context, and templates.
  • Document Q&A: Analysts upload long PDFs or spreadsheets and query them conversationally in a single workspace.
  • AI Cost Consolidation: Replace multiple per-seat AI subscriptions across a small company with one shared credit pool.
  • Rapid Prototyping: Product teams iterate on marketing copy, code, or design briefs across many models in one thread.

pgvector

pgvector

Free

Open-source Postgres extension that adds a vector column type and vector similarity search for embeddings storage and nearest-neighbor queries.

Key features

  • Postgres Extension: Installs as a PostgreSQL extension (CREATE EXTENSION IF NOT EXISTS vector) to add a first-class 'vector' column type directly in the database.
  • Vector Column Support: Allows schema-level vector columns (e.g., vector(3)) enabling storage of fixed-dimension embeddings alongside relational data.
  • Nearest-Neighbor Queries: Provides SQL-accessible operations to insert vectors and query nearest neighbors for similarity search use cases from within Postgres.
  • Multi-language Client Libraries: Maintained official and community client libraries and bindings (Go, Python, Node.js, Rust, .NET, Elixir, C++, etc.) to simplify integration with application code and ORMs.
  • CI & Installer Support: Provides GitHub Actions setup and package installation instructions (e.g., package installs for Ubuntu/Postgres runner images) for automated CI or dev environment provisioning.
  • Open Source & MIT License: Source code and bindings are available under MIT, enabling self-hosting, modification, and community contributions.
  • Postgres extension installable via SQL: CREATE EXTENSION IF NOT EXISTS vector
  • Native vector column type (e.g., vector(n)) for storing embeddings
  • Nearest-neighbor / similarity query support using Postgres queries
  • Language client libraries for Go, Node.js/Deno/Bun/TypeScript, Python, Rust, C++, .NET, Elixir, Nim, and more
  • ORM/driver integrations (Go: pgx, pg, Bun, Ent, GORM, sqlx; Node examples include Prisma/Bun integrations)
  • Client APIs to create and manipulate vectors (constructors, toArray/values/to_vec helpers)
  • Packaging and CI helpers, including GitHub Actions setup and OS packages (example: postgresql-16-pgvector)
  • Examples and test workflows (create DB, run migrations, run language-specific tests/examples)
  • MIT open-source license and public GitHub repositories for source and examples

Best for

  • Semantic Search: Store text or image embeddings in Postgres and run nearest-neighbor queries to implement semantic document search within existing application databases.
  • Recommendation Engines: Keep item and user embeddings in the same Postgres instance to compute similarity-based recommendations with SQL queries.
  • Augmenting Relational Apps: Add embedding columns to existing relational schemas to combine vector search with relational filters and transactions.
  • CI/Dev Automation: Use provided GitHub Actions setup to install pgvector on CI runners or test databases during automated workflows.
  • Language-Specific Integration: Use official bindings (e.g., pgvector-go, pgvector-node, pgvector-python) to insert, index, and query vectors from application code and ORMs.
  • Prototyping Without New DB: Prototype embedding-driven features without deploying a separate vector database by leveraging existing Postgres infrastructure.
  • Semantic search over text/documents by storing and querying embedding vectors inside Postgres
  • Recommendation systems that compute nearest neighbors of item embeddings
  • Similarity matching for images, audio, or other embedded data types within an existing Postgres-backed app
  • Augmenting application databases for retrieval workflows without a separate vector DB
  • Integration into CI/CD workflows (GitHub Actions) and language-specific application stacks using provided client libraries
