Tools for agents

Tools worth giving your agents.

A curated, opinionated directory of tools that integrate cleanly with AI agents and earn their place in an agentic workspace. Some we build at Spark, others are external. Each entry says what it's for and why it's the one we'd reach for.

T / 01

Unformal · Spark Build

Use case

Conversation-first data collection: AI-driven interviews that replace forms and surveys for client intake, user research, and employee feedback.

Why this one

API-native with full REST access, webhooks, and real-time event streams, so an agent can spin up interviews and pull structured insight back without human setup. ~89% completion vs ~23% for traditional forms.

T / 02

Slideless · External

Use case

Turns AI-generated HTML into shareable presentation links, so research and analysis land as readable decks instead of text dumps.

Why this one

Agents publish a deck with a single command, automating generation through distribution. Per-recipient tracking and version history that a wall of text can't offer.

T / 03

Patch · External

Use case

Clients comment directly on a live site; an agent turns those comments into pull requests for developer review.

Why this one

Built to orchestrate agent-driven development: feedback in, PRs out, with developers keeping full control through review before anything ships. Kills the scattered-feedback-to-code grind.

T / 04

Recommand · External

Use case

Peppol-certified e-invoicing: send and receive electronic invoices and procurement documents over the Peppol network, end to end.

Why this one

A clean REST API an agent can drive directly, open-source, end-to-end encrypted, and cheap (free up to 25 docs/month, volume-based after). Does exactly the one job a Peppol integration needs.

T / 05

Infisical · External

Use case

Secrets management: central store for API keys, certificates, and credentials, replacing scattered .env files across every environment and workload.

Why this one

Identity-based auth lets an agent fetch secrets just-in-time without a human pasting keys, the safe way to give agents real access. API-first, open-source, with rotation and an audit trail.
