Draw AV systems with signal logic built in

HTIFA is the local-first pro AV schematic editor built for audio-visual integrators. Sketch signal flow for any AV installation, snap devices from structured libraries, export drawing packages and publish readonly review links when a project needs sign-off.

Workflow

From napkin sketch to drawing set

Everything an integrator does in a schematic, without fighting a generic diagramming tool.

Library

Snap devices with ports that matter

Drop displays, DSPs, codecs, switchers, microphones and control processors from generic presets or downloadable library packs.

✓Port domains prevent incompatible patching
✓Pack devices preserve connector, cable and protocol metadata
✓Custom devices stay editable for project-specific equipment

Canvas

Route, tag, group and adjust

Create normal wires or tagged links, group equipment by area, then tune orthogonal routes with manual offsets and alignment tools.

✓Wire and tag connections are selectable drawing objects
✓Groups stay independent of the devices inside them
✓Minimap, zoom, snap and undo support dense rooms

A review package, one click away

When the schematic is right, produce a readonly share link, watermarked PDF or personal BOM CSV. Pro removes the PDF watermark and adds shared-page BOM downloads.

✓Free includes personal BOM CSV download
✓Pro removes the HTIFA watermark
✓Free accounts include 5 lifetime share links

Built for AV

Purpose-built, not repurposed

Generic diagram tools do not speak signal flow. HTIFA does.

AVoIP & signal-domain routing

Route audio, video, power, control-net, AVoIP (Dante, AES67, NDI), control-io and other AV/IT paths with connector, cable and protocol compatibility checks.

BYOK AI device builder

Bring your own AI key to draft device definitions from datasheet notes. HTIFA keeps designers in control and treats full routing advice as beta.

Device library packs

Start with generic devices, then install free or Pro-gated library packs with real port maps, hardware metadata and cached offline access.

Watermarked PDF and Pro exports

Generate PDFs with title blocks, revision metadata and signal legends. Free includes personal BOM CSV download; Pro removes the HTIFA watermark and lets reviewers download BOMs from share pages.

Review links

Publish readonly browser snapshots for clients and teammates. Free accounts include 5 lifetime shares; Pro removes the share limit.

Local-first control

Drawings autosave in the browser with JSON import/export, undo history and local library-pack cache before anything is shared.

Engineering canvas

Work with groups, tagged connections, minimap, zoom-to-cursor, snap-to-grid, alignment tools and manual route offsets.

Title block metadata

Keep client, project, drawing, revision, drawn-by and checked-by fields with the schematic for consistent PDF output.

Local work stays local

Anonymous drawings autosave in the browser until you publish a share link or use an account workflow.

Pro is for shared handoff

Free can download a personal BOM CSV. Pro removes the HTIFA PDF watermark and lets reviewers download BOMs from share pages.

AI is BYOK

The datasheet assistant uses the designer's own AI key and produces editable drafts, not automatic authority.

Pricing

Start local. Upgrade for real handoff.

No card required to draw locally or download your own BOM. Pro removes the PDF watermark and adds library packs, shared-page BOM download, BYOK AI and unlimited shared diagrams.
