Verdicts

Hark Pro

Free tier includes the assistant capabilities. External API and MCP access were not verified.

LearnHarness

The in-app agent reads files but cannot change them or run commands, and a bundled skill gives other agents a documented read-only view of sessions and the knowledge graph. The project is 14 days old at 0.4.0, its file reads reach the whole home directory without approval, and it has no security policy.

Before you call either

Hark Pro

  1. Hand onboarding to the person using the Hark app.
  2. Do not treat Hark Services integrations as an API for calling Hark.

LearnHarness

  1. Use the bundled skill (skills/learnharness/SKILL.md) to read a learner's record. It needs Python 3.10 or later and writes nothing
  2. Pass --format json before the subcommand, for example python3 -B scripts/graph.py --format json propositions
  3. Treat stored answer keys and teacher prose as model-authored. A proposition in the graph is not evidence the learner understood it
  4. Do not read auth.json, which sits one folder above the data folder and holds provider keys in plain text
  5. Close the app or re-read when a stable snapshot matters. The readers do not lock files while the app writes
