One integration to keep it going.

See the stack Get early access

Your agent. Your model. Your tools.

One integration. The whole connection.

Good connections.
Better follow-through.

The model is only part of the product. Harny connects the accounts, context, and action history your agent needs to work for a real person.

01 / CONNECT

Start with their world.

Bring together what your app knows and what each user chooses to connect. Keep every person’s context scoped to them.

Users · source connections · app context
02 / CONTEXT

Skip the cold start.

Pull the context that matters for the next request. Give your agent something better than another blank slate.

Persistent context · retrieval · relevance
03 / CONTINUITY

Put the past to work.

Record what your agent did, tried, or failed at. Give its next move a history to work from.

Action records · history · inspection
Your product. Your calls.

You choose the model, build the experience, and control what your agent does. Harny supplies context and keeps the outcomes your app reports. Your agent does the acting.

For you and your coding agent

Ship the agent.
Skip the plumbing.

Start with one user. Add context or connect a source. Assemble what your agent needs, then report what it did.

Use the API yourself or let your coding agent help wire it up. Your users approve the accounts they connect.

Building with a coding agent?

The integration guide covers keys, user setup, source connections, context assembly, and error recovery. API, SDK, and MCP setup are part of the early-access onboarding discussion.

Users still authorize their own accounts. Google sources also need approval for your app during early access.

Built around your business

Already have a product?
Give it Harny.

Add an agent to the consumer product you already run. Keep the user relationship and the experience you built.

Established consumer-app teams

Pick up where the user left off.

Your users already have a history with your product. Bring that context and their connected accounts into your agent.

Talk about your app

Independent builders

Small team. Serious ambition.

Put your time into the agent people will use. Start with early access to the infrastructure behind it.

The practical bits

Fair questions.
Straight answers.

Accounts, access, pricing, and who controls what.

Which accounts can users connect?

Gmail, Google Calendar, Google Drive, Notion, and Slack are in the integration lineup. We’ll confirm which providers are enabled for your app during onboarding. Google sources need app approval during early access.

What does the user authorize?

Each user approves access to the accounts they connect through your product. Harny’s connectors are read-only. Your app controls and remains responsible for its agent’s actions. Read the privacy policy →

Can I inspect the context?

Yes. The console lets you inspect assembled context, check source connections, and manage apps and keys. We’re also building an Actions view to track failures and inspect individual action records.

What happens after I request access?

We review your request, work through your integration, and help set up your app. If you need Google sources, we handle your app’s approval as part of onboarding.

How does pricing work?

Free during early access. We’ll announce paid tiers at launch. Tell us what you’re building and how many users you expect.

Where are the technical and legal details?

Start with the integration overview or benchmark methodology. For the terms of integration, read the Developer Agreement. See also the website terms and privacy policy.
