Search for a tool or task, check its pricing, and open its official website. Freemium means a free plan with paid upgrades.

Free self-hosted UI · model costs
Chat with AI models in your own browser-based workspace.
Use the self-hosted UI with its required branding under the current license. There is no included paid-model allowance: cloud APIs, servers and storage can cost extra. Removing branding or qualifying enterprise uses may require a separate license; do not assume the current release is unrestricted BSD.

Free three searches/day · paid Pro
Search the web with AI and see the sources behind answers.
The hosted Free plan includes three searches a day. Pro costs USD 15/month and Max USD 60/month, with model-specific caps. Eligible verified student emails may qualify for USD 9/month Pro; confirm eligibility and billing at the provider.

Free 1,000 credits/month · paid upgrades
Turn web pages into text and data for AI apps.
The hosted Free plan includes 1,000 credits each month. Hobby is USD 19/month billed monthly or USD 16/month billed annually for 5,000 monthly credits. Endpoint credit charges vary; optional paid-plan top-ups and extra usage can add charges.

Free assistant software · provider costs
Connect an AI assistant to the tools and conversations where you already work.
The MIT-licensed assistant software is free to run on your own machine. Cloud models, connected services and hosted machines can require payment; subscriptions or API keys are supplied separately.

Free agent software · provider costs
Use a desktop AI agent with persistent context and integrations across communication platforms.
The MIT-licensed agent can run locally without a software license fee. Model APIs, optional Nous Portal subscriptions, search or other services, and cloud machines may charge separately. A free agent is not free access to every model.

Free self-hosted builder
Prototype AI workflows visually and connect components into runnable applications.
The published Langflow builder has a free self-hosted option. Your server, database, external model APIs and integrations may cost money. Any managed cloud allowance is a separate provider plan, not unlimited free model usage.
