Feynman vs Hyper: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Feynman and Hyper — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Feynman
Companion
Open-source AI research agent that reads papers, ranks literature, drafts research and plans experiments from the terminal or a local workbench.
Key features
- Cited Research Briefs: Asking a research question returns a synthesized brief where each claim is tied to the paper or web source it came from, rather than an unsourced summary.
- PaperRank Scoring: Ranks papers on a topic with transparent evidence for citations, methodology, reproducibility and provenance so reading order is a decision you can inspect.
- Paper Access Resolver: Resolves a single DOI, arXiv ID, OpenAlex ID, PMID, PMCID or title against OpenAlex, arXiv/alphaXiv, DOI and Europe PMC, with optional full-text fetching.
- Local Science Workbench: `feynman serve` opens a standalone app with projects, sessions, chat, notebooks, compute, artifact previews and provenance in one place.
- Claim Auditing and Replication: Compares a paper's stated claims against what its code actually does, and generates replication plans with compute targets and gated experiment steps.
- Local and Hosted Models: Works with hosted providers via OAuth or API key and with local runtimes including LM Studio, Ollama, vLLM and a LiteLLM proxy.
- Skills-Only Install: The research skill library can be installed on its own into Claude, Codex or OpenCode projects without the terminal app or bundled runtime.
- Science Artifacts: Reports, data files, spreadsheets, notebooks, LaTeX, chemistry sketches and genomes are browsable together with versions, lineage and execution logs.
Best for
- Deciding What to Read: Ranking a fresh literature pile on a topic by reproducibility and methodology instead of citation count alone.
- Writing a Literature Review: Producing a review that separates where the field agrees from where questions remain open, with citations attached.
- Verifying a Paper's Claims: Auditing whether the results a paper reports are supported by the code and data it released.
- Planning a Replication: Turning a published finding into a concrete replication plan with a compute target and staged experiment steps.
- Running Deep Research Passes: Launching a multi-agent deep dive on a topic that synthesizes findings and verifies them before reporting.
- Keeping Research Local: Running the whole pipeline against a local model so unpublished work and private data never leave the machine.
- Adding Research Skills to a Coding Agent: Installing the skills bundle into an existing Claude or Codex project to get research workflows without a second app.
Hyper
Hyper
A company knowledge layer that learns from Docs, Slack, Email and Calendar to power smarter, context-aware AI across teams.
Key features
- Unified Knowledge Ingestion: Continuously imports and indexes data from Docs, Slack, Email, and Calendar to build a central, searchable company knowledge graph.
- Contextual AI Plug-ins: Provides an interface and connectors so teams can inject company-specific context into external or internal AI models, improving accuracy and relevance of responses.
- Persistent Institutional Memory: Retains historical context across conversations and workflows so the system remembers past decisions, preferences, and policies without manual re-entry.
- Real-time Sync and Updates: Keeps ingested sources up to date with near real-time synchronization so answers reflect the latest documents, messages, and schedule changes.
- Access Controls & Security: Enables role-based access and privacy controls to ensure sensitive documents and communications are only used where permitted.
- Searchable Knowledge Retrieval: Offers semantic search and retrieval of relevant docs, messages, and calendar events to surface precise context for queries and automations.
- Workflow Automation: Leverages stored knowledge to trigger or assist with routine tasks (e.g., follow-ups, meeting summaries) and reduce manual work.
- Integration Framework: Supports connectors and APIs to integrate with common productivity tools and plug the company brain into existing AI assistants or platforms.
- Ingests and learns from Docs, Slack, Email and Calendar
- Creates a centralized, searchable company knowledge layer
- Integrates/"plugs into" existing AI systems to provide context and memory
- Context enrichment for downstream AI responses and workflows
- Connectors to common collaboration sources (Docs, Slack, Email, Calendar)
Best for
- Onboarding Acceleration: New hires query the company brain to get accurate, contextual answers about processes, past decisions, and team norms without repeatedly asking colleagues.
- Customer Support Enablement: Support agents retrieve up-to-date product docs, past tickets, and policy notes to craft faster, consistent responses to customers.
- Meeting Summaries & Action Items: Automatically summarize calendar events and linked documents, then surface follow-ups and owners based on historical context.
- Internal Knowledge Discovery: Employees search across Slack, emails, and docs to find precedents, design decisions, or technical notes relevant to current projects.
- Automated Follow-ups: Use contextual knowledge to draft or schedule follow-up emails and tasks after meetings, ensuring continuity and reducing manual tracking.
- Compliance & Audit Readiness: Aggregate and index communications and documents to simplify internal audits and demonstrate policy adherence with searchable records.
- Developer and Product Support: Engineers and PMs query past architecture decisions, bug histories, and release notes to speed troubleshooting and planning.
- Provide company-specific context to LLMs and AI assistants
- Centralized knowledge retrieval and enterprise search across Docs, Slack, Email and Calendar
- Faster onboarding by surfacing institutional knowledge
- Automated summarization and context-aware drafting for email and meetings
- Enriching customer-support or internal automation agents with up-to-date company info
