## Which one, for what

### DeepTutor (B)

Good for: A learner, a teacher or a small group that wants a self-hosted tutor over their own documents, with quizzes, research reports, memory and IM companions, or for an agent that hands study tasks to it through the JSON CLI.

Ahead on:
- Reliability, 78 against 25
- Schema & documentation, 71 against 10
- Agent ergonomics, 63 against 0
- Security & auth, 51 against 0
- Payments & pricing, 60 against 30
- Maintenance & community, 84 against 60

Also in its favour:
- No key needed to call it
- Open source

Watch for: The default launch binds the backend to 0.0.0.0 with sign-in off and CORS open to any origin with credentials

### Del (F)

Good for: People who want tasks, notes, reminders and Gmail handled by text on the channel they already use.

Also in its favour:
- No incidents deducted, where DeepTutor loses 3 points for them

Watch for: No API, MCP server or A2A endpoint for an outside agent.

## Verdicts

**DeepTutor.** DeepTutor runs on the owner's machine under Apache 2.0, ships releases every few days with upgrade notes, and gives other agents a JSON CLI with resumable sessions. Its default launch binds all interfaces with sign-in off and permissive CORS, there is no security policy, and two CVEs in 2026 covered a shell-tool RCE and a multi-user MCP bypass, both fixed.

**Del.** Del is a hosted texting assistant and task workspace across iMessage, WhatsApp, Telegram, SMS, Discord and Slack, with a near-daily public changelog and a card-free 14-day trial. No outside agent can call it, no status page or security contact was found, and recent updates let some email actions skip approval.

## Before you call either

### DeepTutor

1. Run `deeptutor run <capability> "..." --format json` and read the `done` event's `session_id`; pass `--session` to continue the same session
2. Configure with `deeptutor config apply setup.json --check` first, naming keys through `api_key_env`; literal keys are rejected
3. Before exposing it beyond one machine, enable sign-in in `auth.json`, set exact `cors_origins` and set `BACKEND_HOST=127.0.0.1` where loopback is wanted
4. Run 1.4.10 or later. Earlier versions carry CVE-2026-51870 (shell tool RCE, fixed in 1.4.1) and CVE-2026-58168 (multi-user MCP bypass)
5. Set `sandbox_allow_subprocess` to false where generated code must run only in the runner sidecar or bubblewrap

### Del

1. Don't plan to call Del from another agent. It answers only the owner's messaging threads and web workspace.
2. Tell the owner web browsing tasks are limited to five a month on Standard and unlimited on Pro.

## Disclosure

- Del competes with LocalGhost, which Anchor Terminal's founder builds. It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default.
