Aside

Aside Computer Inc.

Freemium

A Chromium desktop browser with a built-in agent that signs in and completes real work across your logged-in sites.

Agentic Browsing: The agent operates your logged-in websites directly - clicking, typing and navigating - so tasks that need no public API still get done.
Local Memory: Browsing history is distilled into on-device memory files so the agent already knows which tools and accounts a recurring task involves.
Agent Password Manager: Credentials are autofilled into pages through hardware-backed encryption and Secure Enclave storage, never handed to the model.
Human Approval Gates: Sensitive steps such as payments, posts and outbound messages pause for your confirmation before the agent proceeds.
Access Audit Log: Every credential use and scoped permission grant is recorded so you can see exactly what the agent touched and when.
Routines: Scheduled recurring tasks, such as a 9am daily briefing, run on their own and drop results back into the browser.
Bring Your Own Model: Connect an existing ChatGPT or Claude subscription or your own API key rather than paying twice for inference.
Sandboxed Execution: Filesystem and network access are isolated with guardrails so agent runs cannot reach beyond what the task needs.

Operations Backfill: Push the same record update through several internal dashboards that have no shared API.
Recruiting Prep: Reopen a candidate profile viewed yesterday and assemble interview notes from the sites already visited.
Inbox and Comment Triage: Draft replies, follow-ups and comment responses across email and social accounts under review.
Daily Briefing: Schedule a routine that gathers overnight metrics and trending topics into one morning summary.
Sales Research: Work through prospect sites and CRM screens to collect context before an outreach sequence.
Spreadsheet and Document Work: Have the agent edit local files and web spreadsheets as part of a longer task.

Paid

API for a specialized AI agent that navigates any web property and reliably completes checkouts, subscriptions, invoices, and orders.

Composable Transaction Workflows: Assemble the specific steps a flow requires — shipping, 3DS, login, coupon — while always landing on a cleared transaction.
PCI-Compliant Payment Stack: Built-in card handling and payment execution so cards never touch your servers and transactions actually clear.
Idempotent, Retry-Safe Execution: Every step is designed to survive retries without double-charging or partial orders, with conditional branching for real-world edge cases.
Universal Web Coverage: Runs against any web property — e-commerce checkouts, custom carts, intranet portals, vendor portals, login-gated flows.
Async API with Webhooks: A single POST /checkout returns a taskId; STARTED, COMPLETED, and FAILED webhook events keep your app in sync with agent progress.
Payment and Shipping Profiles: Reusable buyer, card, and shipping profiles let one API call target arbitrary product URLs across sites.

Embedded Checkout in AI Apps: Give a chat or agent product the ability to actually buy the item it just recommended, without building site-specific integrations.
Automated B2B Procurement: Have an agent submit orders and pay invoices across dozens of vendor portals with different login and PO flows.
Subscription Sign-Up Automation: Programmatically enroll users into third-party subscriptions when a first-party API doesn't exist.
Retail Price-Trigger Buying: Auto-execute purchases the moment a monitored product hits a target price or restocks on any supported site.
Agent-Driven Bill Pay: Let agents pay recurring invoices on portals that require login and manual navigation.
