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.

Autophonix, LLC

Paid

Voice AI platform for building inbound and outbound phone agents, priced from 2 cents per minute with record-setting audio accuracy.

Multi-Transcript Audio Fusion: Combines several transcription models with direct audio-to-LLM input so noisy calls, accents and spelled-out identifiers resolve correctly instead of drifting off-script.
Three Flat Per-Minute Tiers: Spark (2c), Bolt (5c) and Storm (9c) trade latency against audio understanding and instruction following, and a workload can be moved between tiers at any time.
Inbound and Outbound Campaigns: Place or receive calls, or run bulk outbound campaigns with pacing and retries, including TCPA-compliant cold outbound via ThunderHuman.
40+ Language Support: Understands accents and mixed-language calls and switches language mid-conversation when a caller asks.
Native SIP Trunking and DTMF: Connects existing telephony without rebuilding routing and handles keypad input for IVRs and confirmations.
Knowledge Grounding: Agents answer from uploaded documents with built-in retrieval, with search testing before deployment.
Live Supervision: Watch calls in progress and whisper guidance to the AI mid-conversation without the caller hearing.
No-Code Platform plus REST API: Operators launch agents from a front end with A/B experiments and AI-graded test calls, while developers POST to /v1/calls against the same runtime.

24/7 Front Desk: Answering inbound customer support and reception calls around the clock without staffing a night shift.
Appointment Scheduling and Reminders: Running outbound reminder and rescheduling campaigns with pacing and automatic retries.
Parts and Inventory Lookup: Handling field-service calls where part numbers and addresses must be transcribed exactly under site noise.
Pre-Sales Qualification: Screening inbound leads and warm-transferring qualified callers to a human with context preserved.
Healthcare Call Automation: Running patient-facing phone workflows under a HIPAA BAA with US data residency.
Call Center Cost Reduction: Replacing outsourced per-minute agent spend with a 2-9 cent per-minute automated stack.
Embedded In-App Voice: Adding a voice agent inside a web or mobile product using the same runtime as the phone channel.
