The signature grid

Chapter II · What's inside

A complete sheet — and then some.

Every D&D 5e mechanic a player needs to keep their head in the game — complete with a calendar, interactive inventory, journal entries, party vaults, roll tables, shop generator, and so much more.

Grid Inventory

Drag, drop, and organize items on a visual grid. Items have real sizes. Containers can nest inside each other. Carry weight updates live.

II.

Full Spell Catalog

Every Player's Handbook spell plus Tasha's / Xanathar's / Fizban's additions, with damage rolls, save DCs, components, and class filters. Prepared vs. known rules enforced per class.

III.

Real-Time Party Sync

Share vitals, conditions, and loot with your whole group. And the DM gets extra tools! Push items, manage party inventory, and coordinate rests in real time.

IV.

AI Portraits & Icons

Generate unique character portraits and item icons on demand. Token-based, optional, and never required. Make them heroic, cursed, or somewhere in between.

Offline-First

Play with your characters anywhere. Once loaded, the app runs without a connection. Your data lives on your device and exports to plain JSON so you can take it with you.

VI.

Homebrew Workshop

Custom races, classes, subclasses, spells, items, feats, with full mechanical support that reflects in your sheet! Per-mechanic edition toggles let you mix 5e 2014 and 2024 rules for exhaustion, crafting, and bastions.

VII.

Calendar & Downtime

Track in-game days, run downtime activities, and craft items with Xanathar's rules. Magic item recharges when they say, and time moves when you say it does!

Premium

VIII.

Shop & Bastion

Generate randomized shops by settlement size and type. Build and upgrade your bastion stronghold with D&D 2024 rules. DMs can push items and loot directly to the party.

Premium

This started as a way to help my players visualize their sacks of equipment. It has since become a way to support the mechanics we often overlook, and to share ideas across the table. I want to extend that to every player — and to help any DM keep their players involved in their world.

Tabletop Inventory Manager is free to use, and Premium is a one-time purchase. $3.99, and all the extra tools are yours. It runs in any browser, on any device, with native versions coming soon. Your characters export to plain JSON, so you can migrate them to any device.

No subscription. No ads. No account required to play. Just a sheet that works the way the rules intend.

— Built by a single humble DM, for D&D players.

Chapter V · Rumors 'round the tavern

Likely to be asked.

If you have a question that isn't here, write to silosupport@gmail.com. It's me there. You will speak to a human~

Is this an official D&D product?

No. TTI is fan-made and uses the SRD 5.1 content under Creative Commons Attribution 4.0. Not affiliated with Wizards of the Coast.

Can I play offline?

Yes. Once the app loads, it runs without a connection. Party sync and AI generation require the internet; everything else does not.

Does TTI support 5.5e / 2024 rules?

Yes, via per-mechanic toggles in Settings: exhaustion (2014 vs. 2024), crafting (PHB vs. Xanathar's), death saves, bastion unlock level, and more. A unified edition switch is on the roadmap.

Can I add homebrew content?

Yes! The Content Workshop (premium) supports custom races, classes, subclasses, spells, items, feats, and backgrounds. Homebrew slots into character creation the same way official content does.

Is there a web version?

You're one click from it. Open the app in any modern browser; desktop, tablet, or phone. No install required.

iOS?

Planned after the Android launch stabilizes. The web version already works on iOS Safari. You can add it to your home screen and it behaves like a native app.

How do I get support?

Email silosupport@gmail.com. Bug reports, refund requests, feature ideas — all go to the same place. Response time is a day or two, usually faster.
